Affect regulation models posit that aversive affective states drive binge-eating behavior, which then regulates negative emotions. However, recent findings among individuals with binge-eating disorder (BED) suggest that food-related anticipatory processes may precede and potentially explain the negative affect thought to drive binge eating. Specifically, studies using ecological momentary assessment (EMA) demonstrate that the negative affective state of "Guilt" (from the Positive and Negative Affect Schedule) most strongly predicts later binge eating in the natural environment, and it has been hypothesized that planning a binge or feeling that a binge-eating episode is inventible may account for the increases in Guilt observed prior to binge episodes. In the present study, we tested the hypothesis that binge planning or inevitability may contribute to feelings of shame (a key facet of the broader Guilt construct), which then predict binge-eating episodes, using EMA in 43 individuals with BED. Consistent with hypotheses, feelings of binge inevitability and planning prospectively predicted binge-eating episodes. Further, binge planning predicted subsequent increases in shame. However, shame did not predict subsequent increases in binge planning. Finally, a mediation model revealed that binge planning (Time 1) predicted future binge eating (Time 3) directly and indirectly through increases in shame (Time 2). The results provide novel evidence that individuals with BED anticipate and actively plan for binge-eating episodes, and that binge planning may explain the increased shame/guilt typically observed before binge eating. Overall, accruing evidence suggests that negative affect, although predictive of binge eating, may be better conceptualized as a consequence of the anticipatory processes that lead to binge eating, rather than the starting point, at least among some individuals with BED. Future experimental research is needed to more conclusively test this hypothesis., Competing Interests: Declaration of competing interest None.

Binge eating (BE) is consuming large amounts of food in a short time, while experiencing loss of control over eating behavior. BE can be hereditary, and juvenile stress (JS) may contribute to its onset. We examined the impact of JS on BE-like behavior, in an animal model of intergenerational BE. Twenty-four female Wistar rats received 2-h access to palatable food (PF) three or five times a week (3 TW or 5 TW) for 4 weeks, followed by the open field test (OFT). At postnatal day (PND)27-29, female offspring either underwent JS (O-JSC) or not (O-CC). At PND51-53, offspring's stress levels were assessed behaviorally. At PND70-85, offspring received 2-h access to PF three times a week to assess their BE-like tendency. Hair samples were collected afterwards. Compared to 5 TW, 3 TW had a greater binge size. In the elevated plus maze and dark\light box, in O-JSC, offspring of 3 TW (O-3TW) spent less time in the open arms and lit area compared to O-5TW. O-3TW consumed more PF than O-5TW. O-JSC consumed more than O-CC. O-3TW-JSC had higher hair CORT levels than O-3TW-CC and O-5TW-JSC. This study highlights the interplay between maternal and offspring experiences, allowing for the study of underlying mechanisms., Competing Interests: Declaration of competing interest The authors do not have any conflicts of interest to declare., (Copyright © 2024 Elsevier Ltd.

Objective: "Feeling fat", the somatic experience of being overweight not fully explained by objective body weight, is considered to be an eating pathology maintenance factor. The traditional clinical understanding of "feeling fat" is based on the body displacement hypothesis, which suggests that negative emotions are projected onto the body and experienced as "feeling fat" in lieu of adaptive emotion regulation. A more recent theory suggests that "feeling fat" occurs in response to thought-shape fusion (TSF), a cognitive distortion in response to the imagined consumption of perceived fattening food. The present experimental study compared the roles of these two proposed mechanisms of "feeling fat" using self-report and psychophysiological measures., Method: Eighty-two women (41 with binge eating, 41 control participants) self-reported "feeling fat" and had their heart rate variability (HRV), a physiological index of emotion regulation, measured before and after imagined inductions. Participants imagined either a personalized negative affective experience or consuming a preferred, so-called 'fattening' food., Results: The TSF induction increased self-reports of "feeling fat" among participants with binge eating but not among control women. The negative affect induction did not increase self-reported "feeling fat" in either group. HRV did not significantly change in response to either induction for either group., Discussion: TSF may be a more potent precursor to "feeling fat" than negative affect for individuals with binge eating. This may suggest new treatment directions, such as cognitive defusion from TSF when patients experience "feeling fat." The utility of HRV in monitoring "feeling fat" is questionable., (© 2024 The Author(s). International Journal of Eating Disorders published by Wiley Periodicals LLC.)

Background: Body shame is an established antecedent and maintaining factor of binge eating, beyond global negative affect and body weight, and partly through the effects of dietary restriction. These associations have mainly been established in women and are understudied in men. Body image flexibility, a concept from Acceptance and Commitment Therapy, may be a protective psychological process against the effects of negative body image on binge eating., Methods: Using structural equation modeling and a non-clinical sample of 244 women and 185 men, this cross-sectional study tested an integrated model of the association between body shame and binge eating, mediated by dietary restriction and moderated by body image flexibility, controlling for depressive symptoms and BMI., Results: Body shame predicted binge eating in women but not in men, whereas depressive symptoms predicted binge eating in men but not in women. Body image flexibility moderated the association between body shame and binge eating in women., Conclusions: These cross-sectional findings highlight the importance of considering gender differences in current negative affect models of binge eating, and further support the role of body image flexibility in attenuating the influence of body shame on binge eating in women. Longitudinal studies are required to examine the temporal dynamics between these variables., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Objective: Binge eating is a mental health disorder related to weight gain, whose prevalence/correlation with weight excess in people with HIV (PWH) have been scarcely investigated.Design: A cross-sectional study of PWH who underwent the validated Binge Eating Scale (BES) questionnaire., Methods: We included adult PWH during routine visits from October 2022 to February 2023. The BES questionnaire was administered with the support of a psychiatrist (score <17 binge eating very unlikely, binge eating ≥17 possible/very likely). We performed a logistic regression for the binary outcome BES at least 17 and being overweighted/obese as effect measure of risk association, and then adjusted for possible confounders (as integrase inhibitor exposure) and performed a sensitivity analysis fitting the regression model including and excluding depression (which may drive binge eating)., Results: We included 1204 PWH, 75.2% men, median age 53 years [interquartile range (IQR): 44-60], 95.6% with undetectable HIV-RNA. As for BMI, we had overweight and obesity in 35.1 and 19.4% cases. Considering BES, 1089 (90.4%) PWH had a score less than 17, 115 (9.6%) at least 17. Multivariable analysis showed that obesity [odds ratio (OR) = 6.21, P  < 0.0001), overweight (OR = 2.21, P  = 0.006) and depression (OR = 1.98, P  = 0.028) were significantly associated with high BES score. By excluding depression, our results were confirmed, and obesity/overweight remained significantly associated with binge eating (obesity OR = 6.58, P  < 0.0001, overweight OR = 2.17, P  = 0.023)., Conclusion: Binge eating should be considered among possible causes of weight gain in PWH. Our results push towards an in-depth study of this topic for a better understanding of the phenomenon in PWH, possibly identifying subgroups of this population who could benefit from a psychoeducational/psychological intervention to preventing WG., (Copyright © 2024 Wolters Kluwer Health, Inc.

Dialectical Behaviour Therapy (DBT) has demonstrated effectiveness in reducing harmful behaviours associated with emotion dysregulation, including non-suicidal self-injury (NSSI) and binge eating. It has been hypothesized that the effects of DBT on NSSI and binge eating are the result of improvements in emotion regulation (ER); however, the extent to which changes in ER account for reductions in these behaviours is unclear. The present study leverages two unique clinical samples to examine the degree to which changes in ER influence changes in the frequency of NSSI and binge eating over the course of DBT. Participants included 189 Veterans receiving outpatient DBT and 117 civilians enrolled in a DBT Intensive Outpatient Program. Analyses examined changes in ER, binge eating and NSSI over the course of treatment, as well as the extent to which NSSI and binge eating frequency were influenced by changes in ER. In the Veteran sample, DBT led to improvements in ER abilities and significant reductions in NSSI and binge eating; however, changes in ER did not account for observed reductions in NSSI or binge eating. In the civilian sample, the effects of DBT on ER, NSSI and binge eating were nonsignificant. Our findings suggest that ER may not be the only mechanism through which DBT exerts its effects on NSSI and binge eating. The effects of DBT on ER and self-damaging behaviours may vary based on factors such as treatment setting, time in treatment and clinical severity of the sample., (© 2024 John Wiley & Sons Ltd.)

Borderline personality disorder (BPD) is characterized by unstable self-image, conflictual interpersonal relationships, emotional dysregulation, and marked impulsivity. One form of impulsivity commonly seen in BPD is binge eating; however, little is known about this maladaptive behavior in the context of BPD. In the eating disorder (ED) literature, multiple theories suggest binge eating occurs as a result of heightened levels of negative affect. Given that BPD and EDs share emotional dysregulation and impulsivity as maintaining mechanisms of each respective disorder, these theories of binge eating may provide a model for binge eating in BPD. Existing literature suggests feelings of emotional emptiness may precede binge episodes in those with EDs. The current study sought to explore feelings of emptiness as antecedents to binge eating behaviors in those with BPD traits. Using ecological momentary assessment, binge episodes, affect, and feelings of emptiness were tracked throughout the day for 14 days in undergraduate students with BPD traits ( n = 55). The current study found momentary feelings of emptiness at the time of the binge eating episode significantly predicted increased odds of a binge episode occurring. Additionally, momentary feelings of emptiness, as well as other negative affects, increase following a binge episode. Results suggest treatment of binge eating within BPD should include elements of acceptance of negative affects including emptiness, such as in dialectical behavior therapy distress tolerance skills training.

Objective: In cross-sectional and retrospective research, parental binge eating is associated with their children's eating psychopathology. The current study extended the evidence by cross-sectionally and longitudinally examining the relation between parental binge eating and binge eating and weight-control behaviors in the next generation of their adolescent children and young adult children in a population-based sample., Methods: Adolescents (Time 1: M = 14.5, SD = 2.0 years) (n = 2367), followed into adulthood (Time 2: M = 22.1, SD = 2.0 years), and their parents (n = 3664) were enrolled in EAT 2010-2018 and Project F-EAT 2010. The current study examined parental binge eating, and child binge eating and weight-control behaviors. Adjusted models covaried for child gender, age, and race/ethnicity., Results: Approximately 7% of adolescents at Time 1 had at least one parent who reported binge eating with no differences by child's age, gender, or race/ethnicity. Having at least one parent experiencing binge eating at Time 1 (vs. not) was associated cross-sectionally with adolescent children's use of extreme weight-control behaviors (9.6% vs. 4.8%; Risk Difference [RD] = 4.9%) and associated longitudinally with binge eating during young adulthood (21.1% vs. 11.6%; RD = 9.5%). Other associations did not reach statistical significance., Conclusions: Children of parents with binge eating appear to have elevated risk of extreme weight-control behaviors during adolescence and binge eating in young adulthood. Clinicians should assess whether eating psychopathology extends to other family members, and offer additional support to parents with binge eating. Further research is needed to identify risk factors in the children of parents with binge eating and to assess strategies for prevention., (© 2024 Wiley Periodicals LLC.)

Objective: Food addiction (FA) shows phenotypic and diagnostic overlap with eating disorders characterised by binge eating, though it is unknown how momentary processes driving binge-eating symptoms differ by FA. The present study examined the possible moderating influence of FA severity on momentary mechanisms underlying binge-eating symptomatology using ecological momentary assessment (EMA)., Method: Adults (N = 49, mean age = 34.9 ± 12.1, cis-gender female = 77.1%) who met criteria for FA and/or binge-eating disorder completed baseline measures including the Yale Food Addiction Scale (YFAS) followed by a 10-day EMA protocol. Generalised linear mixed models assessed main effects of YFAS, momentary antecedents (affect, impulsivity, food cue exposure, appetite, and eating expectancies) and two-way interactions between YFAS and within-person antecedents., Results: FA severity moderated momentary associations between food cue exposure and subsequent binge-eating symptoms: the association was stronger among participants with lower but not higher YFAS scores. No other interactions were significant., Conclusions: Some functional associations underlying binge-eating symptoms vary based on individuals' level of FA symptoms. Future research to further understand how observed associations may differ amongst diverse populations and over course of illness may also inform future prevention and interventions., (© 2024 Eating Disorders Association and John Wiley & Sons Ltd.)

Objective: Negative affect is central to eating disorder maintenance models; identifying mechanisms underlying this link may inform specific treatment targets. The current study evaluated which emotions (i.e., distress, fear, and moral emotions) were most strongly linked to feeling fat and tested feeling fat as a longitudinal mediator of the relationship between these emotions and restricting or binge eating (https://osf.io/3d5cq/)., Method: Community adults (N = 714, M[SD] age = 41.5[13.7], 84.6% female, 85.9% white) provided data at baseline, 3-month, and 6-month follow-up. Relative weights analysis examined which emotion categories exhibited the strongest longitudinal relationships with feeling fat. Cross-lagged panel models tested feeling fat as a mediator of the relationship between emotions and eating disorder behaviors., Results: Distress and moral emotions were the strongest emotional predictors of feeling fat. Feeling fat predicted binge eating (p's < 0.001), but not restricting (p's ≥ 0.832), in random effects cross-lagged panel models. Feeling fat partially mediated the longitudinal relationship between distress and binge eating (p = 0.044); however, this effect became nonsignificant after adjusting for BMI (p = 0.354). Feeling fat did not mediate relationships between moral emotions and binge eating or between either distress or moral emotions and restricting (p's ≥ 0.638)., Discussion: Feeling fat was associated with binge eating, not restricting, highlighting the importance of specificity in maintenance models. Because the mediating effect of feeling fat was accounted for by body size, factors associated with body size, such as internalized weight stigma, may be more relevant mediators of the relationship between negative emotions and eating disorder behaviors. Future research on feeling fat should adjust for body size., (© 2024 The Author(s). International Journal of Eating Disorders published by Wiley Periodicals LLC.)

Objective: Research demonstrates associations between poor social cognition and eating disorder (ED) pathology. Moreover, research shows that individuals with EDs struggle with emotion regulation. The present study replicates and extends the literature on social cognition and ED pathology, which previously focused largely on symptoms of anorexia nervosa among women while the present study focuses on symptoms of bulimia nervosa among undergraduate men. Further, this study tests the hypothesis that better emotion regulation mitigates the association between social cognition and ED pathology., Methods: At a single timepoint, undergraduate males (n = 520) completed a series of questionnaires, and a task assessing mentalising, a key element of social cognition., Results: Consistent with hypotheses, bulimic symptoms were associated with worse mentalising and worse self-reported emotion regulation. Moreover, the association between mentalising and bulimic symptomatology was conditional on emotion regulation, such that it was strongest among those with more difficulties regulating their emotions., Conclusion: Results are consistent with existing theories that highlight an interplay between interpersonal (e.g., mentalisation) and intrapersonal (e.g., affective functioning) factors in relation to ED symptomatology. Among undergraduate males, bulimic symptoms were associated with worse mentalisation. However, a good ability to regulate emotions interrupted this association., (© 2024 Eating Disorders Association and John Wiley & Sons Ltd.)

Objectives: Binge eating disorder (BED) is the most prevalent eating disorder associated with multiple adverse health effects, especially mental health issues, including substance use disorders and mood and anxiety disorders. Given these high comorbidities, the objective of our study was to examine whether bingeing behavior would lead to altered perception of reinforcing properties of EtOH and changes in well-being. Methods: We used a sucrose bingeing model based on an intermittent access paradigm with a two-bottle choice, without fasting, in male and female mice. We examined the effect of 2-week sucrose paradigm on ethanol-reinforcing properties using a conditioned place preference test (CPP). Well-being, anxiety- and depressive-like behavioral tests were performed to assess emotional state following 2 and 8-week sucrose bingeing paradigm. Results: Mice with intermittent access to sucrose developed a binge-like behavior assessed by higher sucrose intake and escalation rate during the 1st hour of access, in comparison with mice with a continuous sucrose access. We show for the first time that sucrose bingeing in mice modifies positive reinforcing effect of EtOH in a CPP paradigm without marked alteration of emotional state. Interestingly, prolonging sucrose access for 8 weeks revealed an exacerbated bingeing behavior in female mice, and some signs of emotional state alterations in female with continuous access. Discussion : In sum, our findings broaden the understanding of behavioral alterations associated with bingeing, highlighting the need to investigate addictive-like properties of palatable food both in male and female mice.

Background: When individuals follow a diet or limit their food intake, they activate cognitive restraint, which is defined as a mental effort to restrict dietary behavior with the goal of losing weight. As an example, fasting has also been associated with the recruitment of cognitive restraint, but further research is needed to fully understand its underlying mechanisms., Aims: The aim of this study was to examine the relationship between the duration of fasting and disordered eating, such as food cravings, binge eating, and potential changes in eating habits., Methods: An online survey was conducted among 853 first-semester university students to investigate their fasting practices and frequency over a three-month period prior to data collection. Participants who were on diets were excluded (n=214). After controlling the sample for biases, a comparison was made between 89 fasters and 369 non-fasters. The study compared levels of cognitive restraint, binge eating, food cravings, and consumption of 'forbidden' foods. A Poisson model was used to examine the association between hours of fasting and disordered eating traits. In the context of this study, the rate ratio was used to examine the relationship between fasting hours and disordered eating characteristics, such as binge eating and food cravings., Results: The study found that fasters experienced an increase in food cravings and binge eating. However, fasters consumed fewer bread slices than non-fasters. The rate ratio of fasting hours practiced is 115% higher among binge eaters (RR 2.15; CI95% 1.70-2.73) compared to those who did not binge. The rate ratio of fasting hours is 29% higher in participants with moderate binge eating (RR 1.29; CI95% 1.05-1.59), increasing to 140% (RR 2.40; CI95% 1.86-3.11) in people with severe binge eating. As for food cravings (state), the rate ratio was 2% higher (RR 1.02; CI 95% 1.01-1.03) for each increase in the unit of the scale., Conclusions: Our study has indicated that fasting is positively associated with increased levels of binge eating and food cravings., (Copyright © 2024 National Medical Association.

Introduction: Previous studies investigated the impact of weight-related abuse (WRA) on eating pathology. However, the circumstances of such an effect are still unclear. Our study aimed to examine the relationship between verbal WRA and binge eating (BE) behavior via attentional bias (AB) to threat cues and difficulties in emotion regulation., Method: We conducted a parallel mediation model. On the basis of the purposive sampling method, 183 individuals with obesity and overweight (70.5% female and 28.4% male; Mean age  = 32.78), from February to June 2019, were recruited from a nutrition clinic in Tehran. The participants completed the BE scale (BES), the weight-related abuse questionnaire (WRAQ), the difficulties in emotion regulation scale (DERS), and the dot probe task (DPT)., Results: AB to threat cues had a significantly negative association with verbal WRA and BE. Difficulties in emotion regulation showed a significant positive association with verbal WRA and BE. The parallel mediation model showed a direct effect of verbal WRA on BE. Moreover, the bootstrap analysis revealed that difficulties in emotion regulation could mediate the association between verbal WRA and BE., Conclusions: Our findings suggest that experiences of verbal WRA can contribute to cognitive bias to negative emotion, maladaptive emotion regulation strategies, and behavioral problems like BE., (© 2024 The Author(s).

Importance: Depression and eating disorders are heightened for adolescents with obesity. Clinical reviews alongside self-report questionnaires are important to ensure appropriate intervention., Objective: To evaluate changes in self-report symptoms of depression, eating disorders, and binge eating in adolescents with obesity during the Fast Track to Health trial., Design, Setting, and Participants: This was a randomized clinical trial conducted from 2018 to 2023. It was a multisite trial conducted at children's hospitals in Sydney, New South Wales, and Melbourne, Victoria, Australia, and included adolescents (13-17 years) with obesity (defined as adult equivalent body mass index ≥30; calculated as weight in kilograms divided by height in meters squared) and 1 or more related complications., Interventions: Duration was 52 weeks including a very low energy diet for 4 weeks followed by intermittent energy restriction (IER) or continuous energy restriction (CER)., Main Outcomes and Measures: Self-report symptoms of depression (Center for Epidemiologic Studies Depression Scale-Revised 10-Item Version for Adolescents [CESDR-10]; scores 0-30), eating disorders (Eating Disorder Examination Questionnaire [EDE-Q]; scores 0-6), and binge eating (Binge Eating Scale [BES]; scores 0-46) were assessed. Adolescents were screened for depression and eating disorders (weeks 0, 4, 16, and 52) and monitored for the onset of new symptoms of disordered eating during dietetic consults., Results: Of 141 adolescents (median [IQR] age, 14.8 [12.9-17.9] years; 71 male [50.4%]) enrolled, median baseline EDE-Q score was 2.28 (IQR, 1.43-3.14), median baseline CESDR-10 score was 9.00 (IQR, 4.00-14.50), and median baseline BES score was 11.00 (IQR, 5.00-17.00). There were no differences between groups for change in CESDR-10 (mean difference at week 52, 0.75; 95% CI, -1.86 to 3.37), EDE-Q (mean difference at week 52, 0.02; 95% CI, -0.41 to 0.45), or BES (mean difference at week 52, -2.91; 95% CI, -5.87 to 0.05). The within-group reductions at week 4 were maintained at week 52, for CESDR-10 and EDE-Q, indicating reduced symptoms of depression and eating disorders. Within-group reductions on the BES were maintained in the IER group only. Seventeen adolescents (12.1%) required support or referral for depression and/or disordered eating, including 7 (5%; 5 IER, 2 CER) adolescents who experienced the onset or reemergence of symptoms during the intervention., Conclusions and Relevance: Results suggest that many treatment-seeking adolescents with obesity self-reported symptoms of depression and eating disorders. Although symptoms reduced for most, some required additional support. Obesity treatment is an opportune time to screen and monitor for depression and disordered eating., Trial Registration: Australian New Zealand Clinical Trials Registry: ACTRN12617001630303.

Weight stigma, racism, and sexism (social devaluation due to body weight, race or ethnicity, and sex or gender), have been linked to increased maladaptive eating behaviors; however, no research has investigated the unique associations between different forms of stigma and eating concurrently. We analyzed within-group (by race/ethnicity and sex) effects of different forms of stigma on maladaptive eating behaviors to test whether there is some unique relationship between weight stigma and maladaptive eating across identities. Additionally, we explored differences by racial/ethnic group and sex, as well as BMI category, in levels of reported weight stigma, racism, sexism, and maladaptive eating. Participants (N = 1051) were recruited so that there were approximately even numbers of participants identifying as Black (33.3%), Hispanic or Latino (32.8%), and White (33.9%). Overall, participants reported similar amounts of weight stigma by race/ethnicity and sex, but different levels of racism and sexism. Weight stigma, but not racism or sexism consistently predicted binge eating and eating to cope across groups, controlling for education, income, BMI, and age. Restricted dieting, however, was only predicted by weight stigma for Hispanic/Latino and Black men. These findings suggest that weight stigma is a unique predictor of maladaptive eating, even when considering the effects of racism and sexism. This study provides evidence of a more focused model of weight stigma and eating outcomes, rather than a more general model of the effect of stigma on eating outcomes due to overall stress. Future research should investigate when and why weight stigma drives restricted dieting, since this relationship seems strongest in men, going against many common inclinations about weight stigma., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Objective: College men may be at risk for binge eating (BE) but are underrepresented in research. This study aimed to examine if body weight/shape concerns, perceived stress, and psychological distress significantly contributed to the likelihood of BE over the past 28 days. Participants: A racially/ethnically diverse sample ( N  = 873) of college men. Method: An anonymous online survey was administered. Logistic regression analysis was conducted to examine the hypothesized associations for the entire sample, and exploratory analyses were conducted within each racial/ethnic group. Results: The model explained approximately 25% of the variance in BE, with body weight/shape concerns as the only significant predictor in the overall sample and for the White, Black, and Asian subsamples; none of the variables were significant among Latino men. Conclusions: Body weight/shape concerns predict BE among diverse college men. The findings have implications for future research, as well as for prevention and intervention for college men.

Background: Food addiction (FA) research has primarily concentrated on binge eating as a symptom of this condition. However, FA may encompass various overeating behaviours, including compulsive grazing - the repetitive consumption of small amounts of food with loss of control. This study extends our previous research by including a clinical sample to investigate whether compulsive grazing exists in a population with higher prevalence and severity of FA. It also examines whether weight or sex moderates the severity or frequency of FA., Methods: Adults between the ages of 20 and 50 years with obesity were recruited from a weight-management clinic (n = 437). Participants completed an online questionnaire to assess various eating behaviours (binge eating, compulsive grazing, reward-based eating) and related personality measures (impulsivity, addictive personality traits). Multiple and logistic regression modelling were used with the Yale Food Addiction Scale symptom count and diagnosis as the dependent variables, respectively. A chi-square test of independence and an analysis of variance were used to determine sex differences., Results: Compulsive grazing was a significant factor in FA diagnosis and symptom severity, confirming earlier work. Binge eating was a significant factor in FA symptom severity. Additionally, females from a weight-management clinic sample were more likely to receive an FA diagnosis than females from the general population. No sex differences were found in males or in the symptom score option for FA., Conclusions: These findings suggest that various compulsive overeating patterns encompass FA. Individuals with obesity and co-morbid FA may require specialized treatments, which may benefit from sex-specific differentiations., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

Objective: Binge eating appears to be associated with impulsivity, especially in response to negative affect (i.e., negative urgency). However, negative urgency is typically assessed via self-report, which captures only some aspects of urgency and may be subject to bias. Few studies have examined impulsivity following experimental manipulations of affect in binge-eating samples., Method: In the present study, individuals who engage in regular binge eating completed a behavioural impulsivity (go/no-go) task with high- and low-calorie food stimuli, once following negative affect induction and once following neutral affect induction., Results: Greater behavioural impulsivity to high-calorie food cues while in a negative (and not a neutral) affective state was associated with more frequent binge-eating behaviour. Further, this behavioural measure of negative urgency uniquely accounted for variance in binge-eating frequency when controlling for self-reported negative urgency, suggesting that behavioural measures may be a useful complement to self-report measures., Discussion: These findings provide novel and compelling evidence for the relationship between negative urgency and binge eating, highlighting negative urgency as a potentially important target for intervention., (© 2024 Eating Disorders Association and John Wiley & Sons Ltd.)

Exposure to persistent mild stress is a frequently encountered chronic challenge in a rapidly evolving society. Depending on various factors including sex, the response to stressors varies and is closely linked to the phenomenon of resilience. Depression and anxiety can be considered maladaptive responses to such stress. In this rat study, we investigated the sex-dependent effects of low-grade systemic inflammation during 1 week in combination with chronic unpredictable mild stress during the following 4 weeks on anxiety-like behavior and episodic feeding behavior. Increased anxiety-like behavior and increased sucrose intake were identified in stressed compared to control animals regardless of sex. Interestingly, two nearly equally distributed subpopulations were found in the stressed groups within each sex at the end of the 5-week protocol of combined stress exposure: the resistant and the susceptible, which were characterized by unchanged and increased sucrose intake, respectively. This difference in susceptibility to protracted combined mild stress and ensuing response to a sucrose eating binge demonstrates the complexity of the underlying regulatory mechanisms associated with emotional hyperreactivity. This model carries the potential for further investigation of the molecular basis of resilience and susceptibility to combined stressors and for testing treatments with potential preventive or therapeutic effects., (© 2024.

Globally, binge eating behavior has emerged as a significant public health concern, especially among female adolescents. Body shape concerns in female adolescents can lead to body dissatisfaction and other mental health issues. Using a cross-sectional study design, we evaluated the frequency of binge eating behavior, body shape concerns, and associated factors among 400 female adolescents. We utilized a pretested Arabic binge eating scale (BES) and a body shape questionnaire-shorter version (BSQ-8C) to collect the required data. We performed Spearman's correlation analysis to find the strength and direction of the correlation between the BES and BSQ-8C scores. Finally, we applied binomial logistic regression analysis to identify the predictors of body shape concerns. Of the studied participants, 5.5% and 6.2% had medium and severe binge eating behavior. We found a significant positive correlation between the BES and BSQ-8C scores (rho = 0.434, p < 0.001). Also, we found that body shape concerns were significantly higher among the monthly family income category of 5000 to 7000 SAR ( p = 0.005), the severe binge eating categories ( p = 0.009), and obese adolescents ( p = 0.001). The present study results can be applied to the development of focused interventions and strategies to address these concerns in this group.

Objective: Binge eating has adverse health effects and may be 10 times more common in people with type 2 diabetes (T2D) than in the general population. Still, binge eating is not consistently addressed in diabetes treatment. People with T2D and binge eating may, therefore, seek guidance on the topic on social media. The study objective was to explore discussions about binge eating among members of a T2D-specific Facebook group., Method: Interactions among members of the Facebook group were observed over 8 months and supplemented by keyword searches within group content. The data were imported into NVivo12 and analyzed using Interpretive Description., Results: The overarching theme described how group members exchanged guidance concerning co-existing T2D and binge eating based on personal experiences while trying to resolve co-members' misapprehensions regarding binge eating. Two subthemes were generated, describing frequently discussed topics relating to binge eating triggers and inhibitors. Triggers were confusion about the health impacts of carbohydrates and encounters with unsupportive clinicians, while inhibitors included the possibility of speaking openly about binge eating with peers and hunger cues being suppressed by glucagon-like peptide 1 receptor agonists., Discussion: Social media may constitute an important source of support for people with T2D and binge eating, as the topic is typically not addressed in routine care. Besides being aware of the extent of binge eating in people with T2D and the health risks involved, clinicians should keep in mind that people with both conditions may seek information on social media that can affect diabetes management., (© 2024 The Author(s).

The association between body mass index (BMI) and binge-eating disorder (BED) is well-established. However, data on the extent to which BMI is associated with progression from binge-eating behavior into BED among adolescents are limited, which was the aim of this investigation. Participants were 9964 U.S. adolescents from the Adolescent Brain Cognitive Development (ABCD) Study, aged 9-13 at the time of study enrollment. A computerized parent-reported assessment was used to establish adolescents' binge-eating behaviors and BED. Cox proportional hazards models adjusting for sociodemographic covariates were used to examine prospective associations between BMI and likelihood of BED onset among a) adolescents with binge-eating behavior, and b) adolescents with no binge-eating behavior. Of 975 adolescents who met the study criteria for binge-eating behavior, 89 (9.1%) subsequently met the study criteria for BED. Of 8989 adolescents with no binge-eating behavior, 82 (0.9%) subsequently met the study criteria for BED. BMI percentile was significantly associated with the likelihood of BED onset in participants with (adjusted HR = 1.03, 95% confidence interval [CI] 1.00, 1.06) and participants without (adjusted HR = 1.05, 95% CI 1.03, 1.07) binge-eating behavior. Results were also significant when examining BMI as a dichotomous predictor (above and below 85th percentile) among those with (adjusted HR = 2.60, 95% CI 1.00, 6.68) and those without (adjusted HR = 6.01, 95% CI 3.90, 11.10) binge-eating behavior. Overall, results indicate that elevated BMI is prospectively associated with a greater risk for BED onset among U.S. adolescents with or without binge-eating behavior. Adolescents with a higher BMI may benefit from screening for binge eating, and prevention/early intervention strategies to mitigate the risk for developing BED., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Dysregulated eating behaviors, comprising subthreshold and clinical binge-eating disorder (BED) and bulimia nervosa (BN), are increasing among the general population, with a consequent negative impact on one's health and well-being. Despite the severity of these outcomes, people with BED and BN often face a delay in receiving a diagnosis or treatment, often due to difficulties in accessing care. Hence, evidence-based and sustainable interventions for eating symptomatology are needed. The present study aims to assess the effectiveness of a web-based 10-session multidisciplinary group intervention based on Dialectical Behavior Therapy (DBT) for BED and BN, aimed at reducing psychological distress and binge-eating-related symptomatology in a sample of patients with dysregulated eating behaviors and including one session of nutritional therapeutic education. A total of 65 participants (84.6% F; age M = 38.5 ± 13.2; experimental group, N = 43; treatment-as-usual group, TAU, N = 22) took part in the study. The results show, after the 9 weekly sessions, a significant reduction in binge-eating-related symptomatology and general psychopathology and an increased self-esteem and eating self-efficacy in social contexts in the experimental group compared to the treatment-as-usual group (T0 vs. T1). Improvements in the experimental group were significantly maintained after one month from the end of the intervention (T2) in terms of binge-eating symptoms, general psychopathology, and eating self-efficacy in social contexts. This study supports the effectiveness of a brief web-based multidisciplinary group intervention in reducing eating symptomatology and psychological distress and enhancing self-esteem and eating self-efficacy in a group of people with dysregulated eating behaviors. Brief web-based interventions could represent an accessible and sustainable resource to address binge-eating-related symptomatology in public clinical settings.

Although research has illustrated that racial disparities in access to treatment for binge-eating disorder (BED) among Black women exist, little is known about the psychosocial related experiences of binge eating behaviors among Black women. Binge eating disorder is characterized by the recurrent consumption of large amounts of food within a brief period, accompanied by a loss of sense of control over the eating and distress over the eating behaviors. Past research has shown that race and gender related stressors are positively associated with emotional eating among Black young adult women and that they may engage in problem-solving coping strategies like identity shifting (conscious and unconscious alterations of thoughts, behaviors, perspective, and appearances) to manage these stressors. Considering the literature, the present study was developed to examine the mediating role of identity shifting in the relationship between gendered racism and binge eating symptoms among young adult Black women. To test this assertion, we administered an online survey to 239 Black women (M age  = 27.32). The results indicated that gender racism significantly predicted both identity shifting and binge eating and identity shifting significantly predicted binge eating. Additionally, identity shifting accounted for 34.5 % of the associations between gendered racism and binge eating symptoms. These findings highlight the importance of exploring experiences of discrimination and coping strategies when considering ways to reduce mental health concerns, such as binge eating symptoms, among young adult Black women., Competing Interests: Declaration of competing interest All authors declare that they have no conflicts of interest., (Copyright © 2024 Elsevier Ltd.

Affective symptoms (e.g., depression, anxiety, shame) are a potent risk factor for binge eating. However, less is known on the role of loneliness as a moderator of affective symptoms and binge eating. This objective of the current study was to investigate main effects and interactions of affective symptoms and loneliness in relation to binge eating in college women. A sample of 556 undergraduate women completed self-report questionnaires of affective symptoms, loneliness, and binge eating. Results revealed significant interactions between each affective symptom variable and loneliness in relation to binge eating, such that loneliness strengthened the positive association of affective symptoms and greater binge eating. The findings of this study demonstrate an important role of loneliness to binge eating among college women, especially those with underlying affective vulnerabilities. More theoretical and treatment-oriented work on the role of loneliness in binge eating is needed to understand mechanisms and interventions/preventions., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2024 Elsevier Ltd.

Background: Sexual minorities have higher rates of anxiety, depression, and binge eating compared to heterosexual peers. Internalized weight bias (IWB) is also higher for sexual minorities when compared to heterosexual peers. However, research has not examined whether the relationships between IWB and anxiety, depression, and binge eating differ among heterosexual and sexual minority adults pursuing bariatric surgery., Objectives: To examine whether sexual orientation (heterosexual or sexual minority) moderated the relationships between IWB and anxiety, depression, and binge eating among adults pursuing bariatric surgery., Setting: University hospital, United States METHODS: Participants included 811 adults who presented for bariatric surgery, 45 (5.5%) of which identified as a sexual minority. Self-reported data were collected as part of a standard preoperative psychological evaluation for surgical clearance. Three separate moderation models were run to test hypotheses., Results: Sexual orientation did not moderate the association of IWB with anxiety or depression. The IWB by sexual orientation interaction was significant for binge eating (F 1856) = 4.84, P = .03, R 2 = .27 such that the association between IWB and binge eating was significantly stronger for sexual minority patients (b = .54, 95% confidence interval {CI} [.36, .70]), compared to heterosexual patients (b = .33, 95% CI [.30, .38])., Conclusions: Minority stress from identifying as a sexual minority may increase vulnerability to binge eating from IWB among bariatric candidates. Future research examining the directionality of the relationship between IWB and binge eating among sexual minorities is warranted., (Copyright © 2024 American Society for Metabolic and Bariatric Surgery.

Cannabis use is prevalent among individuals with binge eating (BE; i.e., the inability to control eating behavior). Yet, only two studies to date (both over 20 years old) have tested if cannabis use relates to clinical severity among BE samples. Characterizing the relationship between cannabis use, eating disorder (ED) severity, and other psychiatric symptoms in BE samples is necessary for informing screening and clinical recommendations. The present study characterized cannabis use among adults with BE and tested between-group and within-group relationships between cannabis use and eating disorder symptoms, alcohol consumption and symptoms, and depression symptoms. Participants ( N = 165) were treatment-seeking adults with at least once weekly BE in the past 3 months who completed clinical interviews and self-report measures before treatment. Over 23% of participants reported cannabis use in the past 3 months, with most persons using cannabis reported using "once or twice" or "monthly." Most persons using cannabis reported cannabis-related symptoms. Persons using cannabis reported significantly greater alcohol consumption and were more likely to report alcohol-related symptoms compared to persons not using cannabis. No associations were observed between cannabis use, eating disorder symptoms, and depressions symptoms. These findings indicate that a notable subset of patients with BE use cannabis and experience cannabis-related problems, and that cannabis and alcohol use may be related for these individuals. Considering legal and sociocultural shifts in cannabis availability and prevalence, results from the present study support screening for cannabis and alcohol use patterns in patients with BE.

Disordered eating behaviors consistently associated with emotion regulation difficulties. However, most studies have focused on affect intensity without considering dynamic affective patterns. We examined these patterns in relation to daily overeating, loss of control eating (LOCE), dietary restraint, and food craving in young adults using ecological momentary assessment (EMA).Adults (N = 24) completed a 10-day EMA protocol during which they reported momentary affect and eating patterns. Generalized linear mixed-models examined each index in relation to eating variable.Higher PA instability (within-person) was associated with higher ratings of binge-eating symptoms (B = 0.15, SE = 0.06, p  = 0.007). Lower NA differentiation (within-person) was associated with higher levels of food craving (B = -10.11, SE = 4.74, p  = 0.033).Our results support previous findings suggesting that acute fluctuations in PA may increase risk of binge-eating symptoms. Further, inability to differentiate between momentary states of NA was associated with cravings. This study highlights the importance of examining multiple facets of NA and PA in relation to eating regulation. Trial registration: ClinicalTrials.gov identifier: NCT02945475.

Problematic alcohol use and binge eating frequently co-occur. High levels of negative affect, negative urgency, and/or shame may increase the likelihood that problematic alcohol use and binge eating co-occur over time., Objective: Examine 1) the temporal relationship between problematic alcohol use and binge eating among college women, who are at high risk for both, and 2) the additive and moderating effects of shared, emotion-based risk factors in models involving both problematic alcohol use and binge eating., Method: In n = 302 college women assessed at two time points across 8 months, we used hierarchical linear regression to invstigate our objectives., Results: Baseline problematic alcohol use and baseline shame independently predicted increases in follow-up binge eating, controlling for baseline binge eating. In addition, the interaction between problematic alcohol use and shame accounted for further variance in subsequent binge eating (the influence of baseline problematic alcohol use on follow-up binge eating was stronger at higher levels of baseline shame). The reciprocal relationship was not significant: baseline binge eating did not predict follow-up problematic alcohol use independently or in conjunction with risk factors. Neither negative affect nor negative urgency showed predictive effects beyond prior behavior and shame. Results support 1) problematic alcohol use as a prospective risk factor for binge eating, 2) shame as an additive predictor of binge eating, and 3) shame as a positive moderator of binge eating prediction from problem drinking., Conclusion: Addressing shame and problematic alcohol use may be warranted in binge eating interventions for college women., Competing Interests: Declaration of competing interest All authors have no conflicts of interest to report., (Copyright © 2023 Elsevier Inc.

Background: Machine learning could predict binge behavior and help develop treatments for bulimia nervosa (BN) and alcohol use disorder (AUD). Therefore, this study evaluates person-specific and pooled prediction models for binge eating (BE), alcohol use, and binge drinking (BD) in daily life, and identifies the most important predictors., Methods: A total of 120 patients (BN: 50; AUD: 51; BN/AUD: 19) participated in an experience sampling study, where over a period of 12 months they reported on their eating and drinking behaviors as well as on several other emotional, behavioral, and contextual factors in daily life. The study had a burst-measurement design, where assessments occurred eight times a day on Thursdays, Fridays, and Saturdays in seven bursts of three weeks. Afterwards, person-specific and pooled models were fit with elastic net regularized regression and evaluated with cross-validation. From these models, the variables with the 10% highest estimates were identified., Results: The person-specific models had a median AUC of 0.61, 0.80, and 0.85 for BE, alcohol use, and BD respectively, while the pooled models had a median AUC of 0.70, 0.90, and 0.93. The most important predictors across the behaviors were craving and time of day. However, predictors concerning social context and affect differed among BE, alcohol use, and BD., Conclusions: Pooled models outperformed person-specific models and the models for alcohol use and BD outperformed those for BE. Future studies should explore how the performance of these models can be improved and how they can be used to deliver interventions in daily life.

Up to 25% of people with type 2 diabetes (T2D) may binge eat which is almost 10 times as many as in the general population. Binge eating is associated with depression, anxiety, and social isolation. Moreover, binge eating may increase the risk of obesity and high blood glucose levels, both of which can accelerate the onset of complications to diabetes and death in people with T2D. Still, little is known about the experiences, needs, and preferences of people with T2D and binge eating that can inform and develop current and future treatment efforts. The aim of the study was therefore to gain in-depth insights into the experiences and biopsychosocial support needs of women and men with T2D and binge eating. Twenty semi-structured individual interviews (65% with females) were conducted and analyzed according to the methodology of Interpretive Description. Four themes were identified: (a) T2D and binge eating: Feeling trapped in a vicious circle; (b) Unwanted outcasts: Responding to continuous criticism; (c) Biomedical relief: Blaming and adjusting the body; and, (d) Silent struggles: Wanting to cease the secrecy. Pertinent to all themes were the guilt, shame, and worries about developing complications that the participants experienced when binge eating despite having T2D. Although binge eating triggered emotional distress, binge eating was at the same time a way of coping with such distress. Implications for treatment and future research are discussed, including the need to systematically assess and address binge eating in routine T2D care., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: PL and IW own stocks in Novo Nordisk.

Aims: The Diabetes Eating Problems Survey - Revised (DEPS-R) is commonly used to assess disordered eating behaviour (DEB) in individuals with type 1 diabetes and has advantages compared to other measures not specifically tailored to diabetes. A score ≥20 on the DEPS-R is used to indicate clinically significant DEB; however, it does not distinguish between eating disorder (ED) phenotypes necessary to guide treatment decisions, limiting clinical utility., Methods: The current study used latent class analysis to identify distinct person-centred profiles of DEB in adults with type 1 diabetes using the DEPS-R. Analysis of Variance with Games Howell post-hoc comparisons was then conducted to examine the correspondence between the profiles and binge eating, insulin restriction and glycaemic control (HbA 1c , mean blood glucose, and percent time spent in hyperglycaemia) during 3 days of assessment in a real-life setting., Results: Latent class analysis indicated a 4-class solution, with patterns of item endorsement suggesting the following profiles: Bulimia, Binge Eating, Overeating and Low Pathology. Differences in binge eating, insulin restriction and glycaemic control were observed between profiles during 3 days of at-home assessment. The Bulimia profile was associated with highest HbA 1c and 3-day mean blood glucose., Conclusions: There are common patterns of responses on the DEPS-R that appear to reflect different ED phenotypes. Profiles based on the DEPS-R corresponded with behaviour in the real-life setting as expected and were associated with different glycaemic outcomes. Results may have implications for the use of the DEPS-R in research and clinical settings., (© 2024 Diabetes UK.)

Introduction: Multiple factors are related to lower weight loss after bariatric surgery. This review and meta-analysis evaluates the influence of several mental and behavioral factors on weight loss., Method: Six electronic databases were searched. Percentage excess weight loss (%EWL) was calculated for all moderator and non-moderator groups of the variables: symptoms of depression, anxiety and binge eating, compliance, physical activity, quality of life, and body image. All moderators, surgery types, and follow-up moments were analyzed separately., Results: In total, 75 articles were included in the review; 12 meta-analyses were conducted. Higher postoperative compliance to follow-up was associated with 6.86%-13.68% higher EWL. Preoperative binge eating was related to more weight loss at 24- and 36-month follow-up (7.97% and 11.79%EWL, respectively). Patients with postoperative binge eating symptoms had an 11.92% lower EWL. Patients with preoperative depressive symptoms lost equal weight compared to patients without symptoms., Conclusion: Despite the high heterogeneity between studies, a trend emerges suggesting that the presence of postoperative binge eating symptoms and lower postoperative compliance may be associated with less weight loss after bariatric-metabolic surgery. Additionally, preoperative depressive symptoms and binge eating do not seem to significantly impact weight loss., (© 2024 The Authors.

Binge eating is characterized as eating a large amount of food and feeling a loss of control while eating. However, the neurobiological mechanisms associated with the onset and maintenance of binge eating are largely unknown. Recent neuroimaging work has suggested that increased responsivity within reward regions of the brain to the anticipation or receipt of rewards is related to binge eating; however, limited longitudinal data has precluded understanding of the role of reward responsivity in the development of binge eating. The current study used data from the Adolescent Brain and Cognitive Development® (ABCD) longitudinal study dataset to assess whether heightened neural responses to different phases of reward processing (reward anticipation and receipt) (1) differentiated individuals with binge eating from matched controls, and (2) predicted the onset of binge eating in an "at risk" sample. Consistent with hypotheses, heightened neural responsivity in the right caudate and bilateral VS during reward anticipation differentiated youth with and without binge eating. Moreover, greater VS response to reward anticipation predicted binge eating two years later. Neural responses to reward receipt also were consistent with hypotheses, such that heightened VS and OFC responses differentiated youth with and without binge eating and predicted the presence of binge eating two years later. Findings from the current study suggest that hypersensitivity to rewards may contribute to the development of binge eating during early adolescence., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Eating Disorders (EDs) and related symptoms pose a substantial public health concern due to their widespread prevalence among both genders and associated negative outcomes, underscoring the need for effective preventive interventions. In this context, deepening our understanding of the interplay between ED symptoms and related protective factors appears crucial. Therefore, this study employed a structural network analysis approach considering both ED symptom dimensions (i.e., drive for thinness, bulimic symptoms, and body dissatisfaction) and related protective factors (i.e., body and functionality appreciation, intuitive eating, and self-esteem) to shed light on how these factors are interrelated. A community sample of 1391 individuals (34.4% men; M age  = 26.4 years) completed a socio-demographic schedule and self-report questionnaires. The network showed that the nodes with the highest positive expected influence were body and functionality appreciation, while those with the highest negative expected influence were eating for physical rather than emotional reasons and unconditional permission to eat (i.e., two components of intuitive eating). Crucially, the most relevant bridges between the conceptual communities "ED symptom dimensions" and "Protective factors" were the negative relations between (a) eating for physical rather than emotional reasons and bulimic symptoms, (b) unconditional permission to eat and drive for thinness, and (c) body appreciation and body dissatisfaction. Finally, age, gender, and body mass index did not moderate any edge in the network. The practical implications of these findings are discussed, especially in terms of preventive interventions for ED symptoms., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Background: Eating-related problems (e.g., binge eating (BE)) and impaired quality of life (QoL) is more prevalent in children with overweight and obesity. This study aimed to investigate changes in self-reported overeating (OE), BE, and QoL in children with overweight or obesity attending multicomponent 10-week lifestyle camps with a 52-weeks follow-up. Additionally, the study sought to investigate whether self-reported OE/BE before camp was associated with changes in QoL., Methods: Children aged 7 to 14-years could attend camp if they had overweight/obesity, were lonely, unhappy, or had social or family-related problems. In this study only children with overweight and obesity were included (n:185). OE, BE, and QoL were measured using self-reported questionnaires., Results: In total, 38 % of the children reported regular BE at baseline. Regular OE, occasional BE, and occasional OE was reported by 14 %, 13 %, and 11 %, respectively, while 24 % reported no eating-related problems. The relative risk of experiencing eating-related problems decreased at 10-weeks compared to baseline. Additionally, the probability of regular OE (RR 0.12 (95 % CI 0.04;0.38) (X 2 = 8.44, p = 0.004)) and regular BE (RR 0.01 (95 % CI 0.00;0.11) (X 2 = 9.91, p = 0.002)) remained lower at 52-weeks relative to baseline. All QoL dimensions improved after camp, and the presence of self-reported OE and regular BE at baseline was significantly associated with lower QoL at baseline, 10 and 52-weeks., Conclusion: Children self-reporting OE and BE may be a particular vulnerable group that needs more support from camp staff and healthcare professionals to improve QoL., Clinical Trial Registration: clinicaltrials.gov with ID: NCT04522921., Competing Interests: Declaration of Competing Interest The authors declare no competing interest related to the present study., (Copyright © 2024 The Authors.

Objective: Appearance focused self-concept (i.e., overvaluing the importance of appearance for self-definition and self-worth) is theorized to predict dietary restraint and binge eating in the short-term (e.g., daily life). Yet, no research has examined whether appearance focused self-concept increases within-persons during a day and if such increases are linked to greater dietary restraint and binge eating for that day. We addressed this gap in knowledge., Method: Sixty-three female university students completed four items from the Beliefs About Appearance Scale as a measure of appearance focused self-concept six times per day (9 am, 11 am, 1 pm, 3 pm, 5 pm, and 7 pm) for 14 days. Daily at 9 pm, they completed measures of dietary restraint and binge eating for that day., Results: Analyzing data from 555 days, latent growth curve analyses revealed a small-to-moderate linear increase in appearance focused self-concept from 9 am to 3 pm that plateaued from 3 to 7 pm. A more rapid linear increase in appearance focused self-concept from 9 am to 3 pm was associated with greater binge-eating frequency during that day, but not with dietary restraint. The findings were observed when adjusting for between-day appearance focused self-concept at 9 am, which was positively associated with dietary restraint and binge-eating frequency., Discussion: Findings are discussed in relation to research on appearance focused self-concept as a risk factor for disordered eating. Findings are also discussed in relation to how sociocultural factors may increase appearance focused self-concept over time. Future research should delve into the within-day dynamic interplay between appearance focused self-concept and disordered eating., Public Significance: Our study revealed a noteworthy increase in the importance women attach to their appearance over the course of a day, correlating with increased binge eating during that day. Additionally, heightened appearance importance at the onset of a day was associated with more dietary restraint and binge eating during that day. These findings suggest a shorter timescale for the connection between appearance importance and disordered eating than previously understood., (© 2024 The Authors.

Objective: The comorbidity of binge eating and heavy drinking (BE + HD) is concerning due to high prevalence and associated consequences. Affective pathways may maintain BE + HD, yet more micro-level research is needed. This study used ecological momentary assessment (EMA) to examine between-person and day-level relationships between positive and negative affect and binge eating or heavy drinking episodes in BE + HD., Methods: Participants (N = 53) were adults with binge-spectrum eating disorders who completed between 7 and 14 days of EMA prior to a treatment for binge eating., Results: Anxiety was highest on days with both binge eating and heavy drinking, while excitement and confidence were highest on days with only heavy drinking episodes for BE + HD. Global negative affect was relatively stable surrounding binge eating episodes. Guilt significantly increased prior to binge eating, and sadness significantly decreased following binge eating. Global positive affect significantly decreased prior to and stopped decreasing following heavy drinking episodes., Discussion: Results support binge eating being negatively reinforced by specific aspects of negative affect, while heavy drinking may be positively reinforced by global positive affect for individuals with BE + HD. Clinicians should incorporate interventions that focus on specific negative affect dimensions and that promote alternative rewarding activities besides heavy drinking., (© 2024 Eating Disorders Association and John Wiley & Sons Ltd.)

Objective: Individuals with eating disorders transdiagnostically engage in binge eating (BE) and/or purging, despite life-threatening consequences. Little is known about factors that contribute to the persistence of these behaviors. This study explored whether habitual control over binge/purge (B/P) spectrum behaviors contributes to symptom persistence and whether negative reinforcement via reductions in negative affect is less influential in maintaining B/P behaviors that are under habitual control and are persistent., Method: Women with BE and/or purging (N = 81) completed self-report measures assessing habit strength of BE and purging. Then, they completed a 14-day ecological momentary assessment (EMA) protocol during which they completed measures of negative affect, BE, and purging multiple times per day., Results: Habitual control over purging was associated with a greater frequency of purging during the EMA period. However, habitual control over BE was not associated with the severity of loss of control eating or the frequency of BE episodes. Habitual control did not moderate temporal relations between negative affect and B/P behaviors during the EMA period. However, exploratory analyses revealed that individuals with a longer duration of BE and greater habitual control over BE showed a less pronounced reduction in negative affect following BE., Discussion: Overall, these findings suggest that purging may be maintained by habitual stimulus-response learning. In addition, they support the possibility that reduction in negative affect may play a less prominent role in maintaining BE that is habitual and persistent., Public Significance: This study investigated whether habit contributes to the persistence of symptoms in women with binge/purge spectrum behaviors and whether negative reinforcement via reductions in negative affect is less influential in maintaining binge/purge behaviors that are under habitual control. The findings suggest that purging may be maintained through habit. This supports the potential utility of habit reversal interventions to decrease habitual purging., (© 2023 The Authors.

The aim of the present study was to evaluate depressive-like, anxiety-like, and perseverative-like behaviors in a binge eating model. Juvenile Wistar rats, using the binge eating model, were compared to caloric restriction, induced stress, and control groups. Rats of the induced stress group presented binge-like behaviors in standard food intake in the second cycle of the experiment when compared to the caloric restriction group and the binge eating model group. Depressive-like behavior was observed in the binge eating model group with longer immobility time ( p < 0.001) and less swim time ( p < 0.001) in comparison to the control group. Anxiety-like behavior was observed by shorter duration of burying latency in the binge eating model group when compared to the induced stress group ( p = 0.04) and a longer duration of burying time when compared to the control group ( p = 0.02). We observed perseverative-like behavior by the binge model group, who made more entries to the new arm ( p = 0.0004) and spent a longer time in the new arm when compared to the control group ( p = 0.0001). Our results show differences in behaviors between the groups of rats studied. These results suggest that calorie restriction-refeeding, along with stress, may lead to depressive-like, anxiety-like, and perseverative-like behavioral changes in male Wistar rats.

Binge eating (BE) is a significant public health concern due to its prevalence and impact on mental and physical health. While research has suggested both negative affect and appetitive traits are associated with BE, few studies have investigated these constructs concurrently. Structural equation modeling (SEM) evaluated relationships between negative affect, reward-related appetitive traits, and BE among 293 adults with overweight or obesity (OW/OB) seeking treatment for BE, overeating, and weight management (m age = 46.6; m body mass index[BMI] = 34.5; 81.2 % female; 20.1 % Latinx, 60.8 % White non-Latinx). BE was related to negative affect (β = 0.53; p < 0.01) and appetitive traits (β = 1.53; p < 0.001). Negative affect and appetitive traits were related to one another (r = 0.42; p < 0.001), and the full model accounted for 77 % of the variance in BE. In an exploratory follow-up analysis, multigroup SEM evaluated the above relationships in models stratified by sex. Exploratory findings demonstrated both negative affect and appetitive traits were related to BE across sex, particularly when examining BE cognitions and behaviors. However, relationships in men depended upon BE assessment tool. These findings highlight that both negative affect and appetitive traits are related to BE, and jointly may represent significant risk and maintenance factors, particularly in adults with OW/OB. Our findings also highlight the importance of future investigation of sex differences in BE and the potential impact of assessment method., Competing Interests: Declaration of competing interest All authors declare that they have no conflicts of interest., (Copyright © 2024 The Authors.

Objective: Although emerging studies examine the inverse relationship between body satisfaction and disordered eating for Black women, it has not been established how racially salient aspects of body satisfaction may have implications for eating behaviors and longitudinal health outcomes., Method: In a longitudinal sample of 455 Black women, we examined whether skin color satisfaction across ages 10-15 was directly related to adult health outcomes at age 40 (e.g., disordered eating, self-esteem, self-reported health, depressive symptoms, and cardiovascular risk). We also investigated the indirect impact of skin color satisfaction on adult health, mediated by body satisfaction, and binge eating., Results: No significant direct or indirect effects of adolescent skin color satisfaction were observed for depressive symptoms or cardiovascular health outcomes. At ages 10 and 12, skin color satisfaction had negative and positive direct effects, respectively, on self-esteem. At age 15, greater skin color satisfaction was directly associated with greater self-reported health. Post hoc analyses revealed that when additionally accounting for adolescent body satisfaction, greater skin color satisfaction was indirectly associated with greater self-esteem and self-reported health, alongside lower cardiovascular risk., Conclusions: Although previous research suggests that in adolescence, Black girls' skin color satisfaction affects both body satisfaction and disordered eating behaviors, this association does not hold into midlife. Rather, post hoc analyses suggest that the lasting effects of adolescent skin color satisfaction are mediated by the longitudinal stability of body satisfaction, which in turn, is associated with adult health outcomes.

WHAT IS KNOWN ON THE SUBJECT?: Bulimia nervosa is characterized by recurrent episodes of binge eating, inappropriate compensatory behaviours to prevent weight gain and excessive mental preoccupation with body weight and shape. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: In this paper, the feelings, thoughts and experiences of an individual with bulimia nervosa are explained, and the positive and negative effects of their experiences during the treatment process are emphasized. This paper offers advice to patients, relatives and healthcare professionals in recognizing and treating bulimia nervosa. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Mental health nurses should organize training, seminars and conferences to raise awareness of society against bulimia nervosa, which is defined as a mannequin disease and therefore creates a positive perception. Mental health nurses, an essential part of the health system, should raise awareness of individuals and families about recognizing, monitoring and supporting the early symptoms of bulimia nervosa., Abstract: INTRODUCTION: Bulimia nervosa is one of the areas where mental health professionals have difficulties due to its nature and course. It is important to understand the factors related to this problem in-depth to discover the dynamics unique to the individual that causes the difficulty, identify new perspectives on these dynamics and identify alternative behaviours, stop stubborn binge-eating attacks and prevent relapse., Aim: It is aimed to provide an in-depth insight into the nature, course and treatment processes of bulimia nervosa through the narrative of the lived experience of an individual living with this problem., Implication for Practice: The perception of beauty seriously impacts the onset and later course of bulimia nervosa and draws attention to the fact that mental health professionals and media workers have important duties to change the concept of beauty equals being skinny, created in society and the media. Quality of perceived social support is very important in preventing, treating and rehabilitating bulimia nervosa. Adopting a more objective approach, which will prevent the positive or negative stigmatization of the disease in explaining bulimia nervosa to the public, should be adopted., (© 2023 John Wiley & Sons Ltd.)

Introduction: Eating disorders (ED) represent a group of very complex and serious diagnoses characterized by emotional dysregulation and impulsivity. New approaches are necessary to achieve effective diagnosis and treatments. Shifting biomarker research away from the constraints of diagnostic categories may effectively contribute to a dimensional differentiation across disorders according to neurobiology (e.g., inflammatory biomarkers). Thus, the aim of our study was to identify inflammatory profiles in patients with ED., Methods: A sample of 100 women with an ED (23.4 ± 8.55 years) and 59 healthy controls (HC) (20.22 ± 4.18 years) was used. K-means cluster analysis was followed to identify inflammatory clusters considering seven blood biomarkers (iNOS, TNFα, COX2, p38, ERK, TBARS and PPARγ). Moreover, a wide assessment of clinical features was conducted., Results: Two distinct clusters were identified. Cluster 1 patients were characterized by higher inflammatory levels of TNF-α, COX2, p38, and ERK, and had more restrictive anorexia diagnosis than cluster 2. Cluster 2 participants showed higher inflammatory levels of iNOS and were older than cluster 1 and controls and had lower BMI than HC. In addition, they had higher levels of bulimic symptoms than those from the cluster 1 and HC, and higher impulsivity than HC. All ED patients (regardless of cluster) showed higher ED symptoms and more trauma than HC., Conclusions: Our study revealed that inflammatory dysfunction may be linked with clinical endophenotypes in ED, one more restrictive (cluster 1) with an inflammation/oxidative endophenotype more cytokine and MAPK/ERK mediated, and the other more impulsive, with more bulimic symptoms (cluster 2) with NO free radical high output source iNOS. Trauma seems to be a vulnerability factor for both endophenotypes., Competing Interests: Declaration of Competing Interest This work was Supported by the Instituto de Salud Carlos III-FIS research grants [grant numbers PI16/01949 and PI13/00781); and cofounded by European Regional Development Funds (ERDF)., (Copyright © 2024 Elsevier Ltd.

Introduction: Binge eating disorder (BED) is a psychiatric illness related to a high frequency of episodes of binge eating, loss of control, body image dissatisfaction, and suffering caused by overeating. It is estimated that 30% of patients with BED are affected by obesity. "Mindful eating" (ME) is a promising new eating technique that can improve self-control and good food choices, helping to increase awareness about the triggers of binge eating episodes and intuitive eating training., Objectives: To analyze the impact of ME on episodes of binge eating, body image dissatisfaction, quality of life, eating habits, and anthropometric data [weight, Body Mass Index (BMI), and waist circumference] in patients with obesity and BED., Method: This quantitative, prospective, longitudinal, and experimental study recruited 82 patients diagnosed with obesity and BED. The intervention was divided into eight individual weekly meetings, guided by ME sessions, nutritional educational dynamics, cooking workshops, food sensory analyses, and applications of questionnaires [Body Shape Questionnaire (BSQ); Binge Eating Scale (BES); Quality of Life Scale (WHOQOL-BREF)]. There was no dietary prescription for calories, carbohydrates, proteins, fats, and fiber. Patients were only encouraged to consume fewer ultra-processed foods and more natural and minimally processed foods. The meetings occurred from October to November 2023., Statistical Analysis: To carry out inferential statistics, the Shapiro-Wilk test was used to verify the normality of variable distribution. All variables were identified as non-normal distribution and were compared between the first and the eighth week using a two-tailed Wilcoxon test. Non-Gaussian data were represented by median ± interquartile range (IQR). Additionally, α < 0.05 and p < 0.05 were adopted., Results: Significant reductions were found from the first to the eighth week for weight, BMI, waist circumference, episodes of binge eating, BSQ scale score, BES score, and total energy value (all p < 0.0001). In contrast, there was a significant increase in the WHOQOL-BREF score and daily water intake ( p < 0.0001)., Conclusions: ME improved anthropometric data, episodes of binge eating, body image dissatisfaction, eating habits, and quality of life in participants with obesity and BED in the short-term. However, an extension of the project will be necessary to analyze the impact of the intervention in the long-term.

Labelling specific psychiatric concerns as 'niche' topics relegated to specialty journals obstructs high-quality research and clinical care for these issues. Despite their severity, eating disorders are under-represented in high-impact journals, underfunded, and under-addressed in psychiatric training. We provide recommendations to stimulate broad knowledge dissemination for under-acknowledged, yet severe, psychiatric disorders.

This study investigated concurrent and prospective associations between measures of reversal learning and attentional set-shifting and eating disorder symptoms at baseline, 3 months, and 6 months among individuals with anorexia nervosa restricting subtype (AN-R, n = 26), AN binge eating/purging subtype (AN-BP, n = 22), bulimia nervosa (BN, n = 35), and healthy controls (n = 27), and explored whether these associations differed by diagnosis. At baseline, participants completed diagnostic interviews, height/weight measurements, and measures of set-shifting (the Intradimensional/Extradimensional shift task) and reversal learning (a probabilistic reversal learning task). At 3- and 6-month follow-up, participants with eating disorders completed assessments of weight and eating disorder symptoms. A one-way analysis of variance found no evidence that baseline reversal learning and attentional set-shifting differed across diagnostic groups. Multilevel modeling analyses indicated that perseverative errors (an index of reversal learning) predicted an increase in purging over time for individuals with AN-BP and BN. Set-shifting errors differentially predicted frequency of loss of control eating for individuals with AN-BP and BN; however, set-shifting was not related to loss of control eating when examined separately in AN-BP and BN. These findings suggest that disentangling facets of cognitive flexibility may help understand change in eating disorder symptoms., Competing Interests: Declaration of competing interest None of the authors report any conflicts of interest with this work., (Copyright © 2024 Elsevier B.V.
