Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years. The resultant regression equation predicts expected TEE from easily acquired variables, such as body weight, age and sex, with 95% predictive limits that can be used to screen for misreporting by participants in dietary studies. We applied the equation to two large datasets (National Diet and Nutrition Survey and National Health and Nutrition Examination Survey) and found that the level of misreporting was >50%. The macronutrient composition from dietary reports in these studies was systematically biased as the level of misreporting increased, leading to potentially spurious associations between diet components and body mass index.

BACKGROUND: Type 2 diabetes is a major public health concern in the United States and worldwide. The dietary inflammatory index (DII) and the energy-adjusted DII (E-DII) are tools that assess dietary inflammation. Previous evidence suggests that obesity can modify the association between inflammation and disease. OBJECTIVE: The aim of this study was to evaluate the association between the DII/E-DII and incident diabetes in self-identified Hispanic women from the Womens Health Initiative (WHI). The secondary aim was to evaluate whether obesity modifies the association between the DII/E-DII scores and incident diabetes. DESIGN: Participants were from the WHI Observational Study and the Clinical Trial Components (except women from the treatment arm in the Dietary Modification Trial) conducted among postmenopausal women in the United States. DII/E-DII scores were calculated from a self-administered food frequency questionnaire at baseline that included 122 food items, of which 12 are representative of Hispanic eating patterns. PARTICIPANTS/SETTINGS: Participants included 3,849 postmenopausal women who self-identified as Hispanic that were recruited for the WHI from 1993 to 1998 at 40 US clinical centers. MAIN OUTCOME MEASURES: The outcome was incident diabetes. STATISTICAL ANALYSIS PERFORMED: Cox regression models were used to assess the association between DII/E-DII and incident diabetes. Models were adjusted for age at baseline, lifestyle-related risk factors, known type 2 diabetes mellitus (T2DM) risk factors, and neighborhood socioeconomic status. Interaction was tested between the DII/E-DII scores and obesity. RESULTS: The incidence of diabetes was 13.1% after a median follow-up of 13 years. Higher E-DII scores were associated with a higher risk of incident diabetes (hazard ratio [HR], 1.09; 95% confidence interval [CI], 1.04-1.14). There was no interaction between E-DII scores and obesity (P = 0.73). CONCLUSIONS: Pro-inflammatory diets, as measured by higher E-DII scores, were associated with a higher risk of incident diabetes. Future research is needed for understanding how the inflammatory potential of diets can be decreased.

Chrononutrition is a rapidly evolving field of nutritional epidemiology that addresses the complex relationship between temporal eating patterns, circadian rhythms, and metabolic health, but most prior research has focused on the cardiometabolic consequences of time-restricted feeding and intermittent fasting. The purpose of this topical review is to summarize epidemiological evidence from observational and intervention studies regarding the role of chrononutrition metrics related to eating timing and regularity in cardiometabolic health preservation and cardiovascular disease prevention. Observational studies are limited due to the lack of time-stamped diet data in most population-based studies. Findings from cohort studies generally indicate that breakfast skipping or the later timing of the first eating occasion, a later lunch and dinner, and a greater proportion of caloric intake consumed in the evening are associated with adverse cardiometabolic outcomes, including higher risk for coronary heart disease, hypertension, type 2 diabetes, obesity, dyslipidemia, and systemic inflammation. Randomized controlled trials are also limited, as most in the field of chrononutrition focus on the cardiometabolic consequences of time-restricted feeding. Overall, interventions that shift eating timing patterns to earlier in the day and that restrict evening caloric intake tend to have protective effects on cardiometabolic health, but small sample sizes and short follow-up are notable limitations. Innovation in dietary assessment approaches, to develop low-cost validated tools with acceptable participant burden that reliably capture chrononutrition metrics, is needed for advancing observational evidence. Culturally responsive pragmatic intervention studies with sufficiently large and representative samples are needed to understand the impact of fixed and earlier eating timing schedules on cardiometabolic health. Additional research is warranted to understand the modifiable determinants of temporal eating patterns, to investigate the role of chrononutrition in the context of other dimensions of diet (quantity, quality, and food and nutrition security) in achieving cardiometabolic health equity, and to elucidate underlying physiological mechanisms.

Objective: To assess maternal energy intake and energy demand during childbirth, to understand the current status of energy management during childbirth, and to provide reference for midwives to manage childbirth. Methods: Thirty-seven deliveries in a tertiary hospital were selected for observational study to compare the energy intake and energy demand of the mothers, and the mothers with energy intake greater than the energy demand were divided into the energy standard group and the mothers with energy intake less than the energy demand were divided into the energy non-standard group. Energy intake is measured by the mother's diet and fluid rehydration, finally, it will be converted into energy. Daily energy demand = energy coefficient * ideal body weight, the daily energy demand was converted into the actual energy demand by the duration of childbirth. Finally, the effects of energy during childbirth on the outcome of pregnancy were tracked and analyzed. Results: There were 19 cases of patients in the energy-attainment group and 18 cases of patients in the energy-unattainment group, energy intake (4517.35 ± 1689.90) KJ and energy demand (3149.00 ± 1294.41) KJ in the energy-attainment group, and energy intake (3117.54 ± 1671.11) kJ and energy demand (4704.66 ± 1941.31) in the energy-unattainment group. kJ. The total duration of childbirth in the energy-attainment group was (512.21 ± 185.67) min, and the total duration of childbirth in the energy-unattainment group was (765.44 ± 315.83) min, and the comparison of the two groups suggests that the total duration of childbirth in the energy-attainment group was less than that in the energy-unattainment group, and the difference was statistically significant (T = -2.953, p < 0.05); three cases of postpartum hemorrhage occurred in the energy-unattainment group, and two cases of neonatal hypoglycemia, and the difference between the two groups was not statistically significant. Conclusion: Mothers in childbirth generally have energy substandard situation, energy substandard affects the progress of childbirth, so midwives can encourage mothers to carry out the appropriate kinds of food in different stages of childbirth, to ensure that the energy intake is sufficient.

Background/Objectives: Xylitol, a natural low-caloric bulk sweetener, is increasingly used as a sugar alternative due to its low-glycemic and low-insulinemic properties. The aim was to investigate the effect of orally administered xylitol, sucrose, and acesulfame potassium (ace-K) on energy intake during a subsequent ad libitum test meal. Methods: In this randomized, controlled, double-blind, crossover trial (ClinicalTrials.gov NCT05671965, 20 December 2022), we included 20 healthy participants with normal body weight. Over four study visits, participants consumed an oral preload containing 33.5 g xylitol, 33.5 g sucrose, or 0.1675 g ace-K dissolved in 300 mL water, or 300 mL pure water as control. Participants were provided with an ad libitum test meal 15 min after the preload consumption, and both energy intake and total energy intake (= preload + ad libitum test meal) were assessed. Blood samples were collected to quantify cholecystokinin (CCK), glucagon-like peptide-1 (GLP-1), glucose, and insulin concentrations. Results: Total energy intake was lower in response to xylitol and ace-K compared to sucrose (pTukey < 0.03), with no differences between xylitol and ace-K or water. Plasma CCK concentrations were higher in response to xylitol compared to sucrose, ace-K, and water (pHolm < 0.01), whereas GLP-1 concentrations did not differ between the preloads. Plasma glucose and insulin concentrations were lower in response to xylitol compared to sucrose (pHolm < 0.01), but xylitol led to an increase in insulin compared to ace-K and water (pHolm < 0.01). Conclusions: The consumption of oral preloads sweetened with xylitol or ace-K prior to an ad libitum test meal result in a lower total energy intake compared to a preload with sucrose.

Background/Objectives: This study aimed to investigate the levels of emotional, restrained, and external eating behaviors (EBs) among adults, categorize them, and analyze their energy and nutrient intake. Methods: A self-reported survey was administered to 522 Korean adults aged 19–64 years to evaluate their emotional, restrained, and external EBs. They were categorized into five types: Non-specific (NS), Emotional (Emo), Restrained (Res), External (Ext), and Combined (Com) EB types. Subsequently, energy intake, intake ratios and levels, and vitamin and mineral intakes were compared after adjusting for sex and age. Results: The Ext type participants consumed energy and an average of 3003.01 kcal per day, while those with Res type consumed 2415.77 kcal. Notably, both the Ext and Com types had higher proportions of excessive energy intake, while the NS and Res types displayed higher proportions of insufficient energy intake. The Emo type yielded a high ratio of lipid intake, while the Com type exhibited high ratios of both lipid and protein intakes. Furthermore, the Res type demonstrated lower vitamin E, niacin, and potassium intakes than the other types. Conclusions: Since the Ext type suggests excessive energy intake, and the Res type suggest intake of vitamin E, niacin, and potassium, identifying EB types provides a novel perspective for nutritional improvement strategies.

Background/Objectives: Persons with multiple sclerosis (MS) are interested in diet as a second-line approach for disease management. This study examined potential variables that correlate with inaccuracy of self-reported energy intake (EI) in adults with MS. Methods: Twenty-eight participants completed two assessment appointments within a 14-day period that included a standard doubly labeled water (DLW) protocol for estimating total energy expenditure (TEE). The participants reported their EI using the Automated Self-Administered 24 h (ASA24) Dietary Assessment Tool. The primary variables of interest for explaining the discrepancy between TEE and ASA24 EI (i.e., inaccuracy) included cognition (processing speed, visuospatial memory, and verbal memory), hydration status (total body water), and device-measured physical activity. Pearson's correlations assessed the association between absolute and percent inaccuracy in reporting of EI with outcomes of interest, followed by linear regression analyses for identifying independent correlates. Results: California Verbal Learning Test—Second Edition (CVLT-II) z-scores and light physical activity (LPA) were significantly associated with mean absolute difference in EI (r = –0.53 and r = 0.46, respectively). CVLT-II z-scores and LPA were the only variables significantly associated with mean percent difference in EI (r = –0.48 and r = 0.42, respectively). The regression analyses indicated that both CVLT-II and LPA significantly explained variance in mean absolute difference in EI, and only CVLT-II explained variance for percent difference in EI. Conclusions: The results from this study indicate that verbal learning and memory and LPA are associated with inaccuracy of self-reported EI in adults with MS. This may guide timely research identifying appropriate protocols for assessment of diet in MS. [ABSTRACT FROM AUTHOR]

Background: New approaches for the management of obesity, a worldwide problem and a major determinant of disability and mortality, are needed. Mastication influences appetite and satiety mechanisms via actual food or sham feeding. However, the effect of mastication of chewing gum, a type of sham feeding, on appetite regulation has not yet been elucidated. Objectives: Our aim was to evaluate the influence of chewing gum on appetite regulation, satiety, energy intake, and weight loss via randomized controlled Trials. Methods: This study was conducted in accordance with the 2020 PRISMA guidelines, and the protocol was registered in PROSPERO (CRD42023432699). Electronic databases MEDLINE®/PubMed, Scopus, and Cochrane Central Register of Controlled Trials were searched from July 2023 to September 2024. The quality of each included study was assessed using the Cochrane risk of bias tool, RoB 2. Results: A total of eight articles with nine RCTs were included in this systematic review. Seven out of nine RCTs evaluated appetite regulation. Five out of seven RCTs reported a significant suppressing effect of hunger, three out of five RCTs reported a significant reduction in desire to eat, and three out of four reported a significant reduction in the desire to eat a sweet snack, all of them compared to the control group. However, the effects on satiety, energy intake, and weight loss are not conclusive. Conclusions: Chewing gum could be a promising non-pharmacological tool for obesity management through appetite regulation; however, further research, with sustained RCTs evaluating the sustained effects of gum chewing on appetite and weight management, is needed.

Although the energy stored in the lean tissue (LT) and adipose tissue (AT) is well known, the energy required to synthesise these tissues is obscure. Theoretically, the energy at the point at which ΔLT/Δ body weight (BW) reaches 100 % on a regression line, which indicates the relationship between ΔLT/ΔBW and the energy required for BW gain, is considered to be the energy expended to synthesise LT. Therefore, we investigated this relationship in rats. Rats were fed diets with different ratios of protein, fat and carbohydrates because their ΔLT/ΔBW values were expected to be different. Six-week-old male Sprague-Dawley rats had ad libitum access to normal (N, n 6), high-fat (HF, n 7) or high-protein (HP, n 8) diets for 4 weeks. The ΔLT/ΔBW was 0·77 in the N, 0·70 in the HF and 0·87 in the HP groups, respectively. The average energy required to gain BW was 8·8 kJ/g in the N group, 7·0 kJ/g in the HF group and 11·3 kJ/g in the HP group. We observed a positive correlation between ΔLT/ΔBW and energy required for BW gain. The regression line demonstrated that the energy expended to synthesise LT was 13·9 kJ/g and AT was −7·9 kJ/g. Therefore, combined with the energy stored in LT, the energy required to accumulate LT is approximately 19 kJ/g, whereas the energy to accumulate AT could not be elucidated. [ABSTRACT FROM AUTHOR]

Background/Objectives: As an endurance multi-sport race, triathlon places significant energy demands on athletes during performance and training. Insufficient energy intake from food can lead to low energy availability (LEA) and Relative Energy Deficiency in Sport (RED-S). We aimed to measure symptoms related to LEA, examine the risk of RED-S, and find how diet relates to the risk of RED-S in highly trained female amateur triathletes. Methods: Our sample was 20 top-performing female triathletes competing in Quarter Ironman (IM), Half IM, IM, or Double IM triathlons for 5.5 ± 2.5 y who were during the preparatory phase of training (training load 11 ± 3.76 h/week, a single workout 84 ± 25 min). Triathletes completed 3-day food diaries, training diaries, and the Low Energy Availability in Females Questionnaire (LEAF-Q). Exercise energy expenditure was estimated using wrist-worn activity trackers. To examine dietary patterns related to the first signs of LEA, predating RED-S, we created two groups: the L-LEA group (LEAF-Q score 0–5, no symptoms related to LEA, low risk of RED-S, n = 10) and the H-LEA group (LEAF-Q ≥ 6, at least one LEA-related symptom, high risk of RED-S, n = 10). Results: The risk of RED-S was prevalent in 30% of female triathletes, and 50% showed at least one symptom related to LEA. Macronutrient intake was similar in all participants, but triathletes from the H-LEA group tended to eat more plant-sourced protein and fiber. They consumed less saturated fatty acids but ingested more significant amounts of n-6 polyunsaturated fatty acids (PUFAn6). Conclusions: We conclude that foods higher in plant proteins, fiber, and PUFAn6 might predispose female triathletes to LEA by reducing the diet's energy density. [ABSTRACT FROM AUTHOR]

Objective: In treating obesity, energy intake control is essential to avoid exceeding energy expenditure. However, excessive restriction of energy intake often leads to resting energy expenditure (REE) reduction, increasing hunger and making weight loss difficult. This study aimed to investigate whether providing nutritional guidance that considers energy expenditure based on the regular evaluation of REE and physical activity could effectively reduce body weight (BW) in patients with obesity. Methods: A single-arm, prospective interventional study was conducted on 20 patients with obesity (body mass index ≥ 25 kg/m2) at the Nagoya University Hospital for 24 weeks. REE and physical activity were regularly assessed, and the recommended energy intake was adjusted based on the values. The primary outcome was the change in BW, and the secondary outcomes included changes in REE and hunger ratings, which were assessed using a visual analog scale. Results: Eighteen participants completed the study, demonstrating a significant reduction in BW after 24 weeks (−5.34 ± 6.76%, p < 0.0001). No significant changes were observed in REE or hunger ratings. No adverse events were reported throughout the study period. Conclusions: Guidance on energy intake based on REE and physical activity was effective for reducing BW in patients with obesity without decreasing REE or increasing hunger. This approach may reduce the burden on patients with obesity while losing BW. [ABSTRACT FROM AUTHOR]

According to the Indonesia Nutrition Status Survey 2022, Central Java highest stunting rate is in Brebes District. In Brebes Regency, the prevalence of stunting increased by 2.8% between 2021 and 2022. The goal of the study was to investigate the risk factors for stunting in toddlers in the Kersana Public Health Center area between the age of 24 and 59 months. This study employed a quantitative approach using a case-control design. Purposive sampling was used to create a sample set of 90. There are two variables in this study, namely the dependent variable (stunting) and the independent variables (family income, mother and father education, immunization, LBW, PBL, birth spacing, mother SEZ status during pregnancy, environmental sanitation, energy and protein intake, IMD, exclusive breastfeeding, complementary feeding, history of diarrhea and respiratory tract infections). The binary logistic regression test on multivariate analysis and the chi-square test were utilized in the bivariate analysis test. The study findings indicated that the following variables were linked to the incidence of stunting: immunization status (p-value=0.000), family income (p-value=0.000), environmental sanitation (p-value=0.000), history of diarrhea (p-value=0.030), early breastfeeding initiation history (p-value=0.006), history of exclusive breastfeeding (p-value=0.003), history of complementary feeding (p-value=0.000), energy intake (p-value=0.000), and protein intake (p-value= 0.001). According to the research, immunization status and energy intake are the two risk variables that have the most significant effects on stunting in children between the ages of 24 and 59 months.

Background: The global rise in obesity has been significantly influenced by shifts in dietary habits that have been exacerbated by external factors such as the COVID-19 pandemic. This study aims to analyze the trends in Romanian dietary habits from 2015 to 2023, focusing on the impact of the COVID-19 pandemic and the role of socio-economic factors, seasonality, and cultural practices. Methods: For dietary habits, we used nationally representative data from the Romanian Household Budget Survey provided by the Romanian National Institute of Statistics. The survey includes 30,000 households annually. From the same provider, we downloaded data about potential drivers of food consumption, such as income, the consumer price index, and the unemployment rate. The analysis mixes descriptive statistics and panel data analysis. Among the main drivers, the econometric models include seasonality and regional factors, ensuring a comprehensive understanding of the changes in dietary behavior. Results: During the COVID-19 pandemic, daily calorie consumption increased to over 3000 calories per person, representing a 20% increase compared to the pre-pandemic period. Post-pandemic, food consumption remains elevated, averaging 2500–2600 calories per person daily. The pandemic also led to a shift in dietary composition, with significant changes. Thus, we mark an increase in fat (p < 0.001) and carbohydrate intake (p < 0.01) and a decrease in protein intake (p < 0.001). Beyond the presence of health disruptors, we confirm the significant impact of income (p < 0.001) and seasonality (p < 0.001). Other factors like unemployment, the consumer price index, and hidden regional factors have a minor role. Conclusions: The COVID-19 pandemic has had a lasting impact on Romanian dietary habits, reinforcing unhealthy eating patterns that were already prevalent. The sustained increase in calorie consumption, particularly of nutrient-poor, energy-dense foods, poses a significant public health challenge. The study also highlights significant seasonal variations, with a marked increase in food intake during the last quarter of the year, driven by cultural and religious traditions. These findings underscore the need for targeted public health interventions and policies that address economic factors and cultural and regional influences to promote healthier dietary behaviors in Romania.

Temporal energy intake (EI) and physical activity (PA) patterns may be associated with obesity. We aimed to derive and characterise temporal EI and PA patterns, and assess their cross-sectional association with weight status, in 6-to-14-year-old Portuguese participants of the National Food, Nutrition and Physical Activity Survey 2015–2016. We extracted times and EI of all eating occasions from two 1-d food diaries/24-h recalls, while types and times of PA from 4-d PA diaries. We derived EI patterns (n 714) and PA patterns (n 595), using, respectively, a hierarchical and K-means cluster analysis, considering the average proportion of total daily EI (%TEI) and PA intensity (%TPA), within each 2-h interval across the 24-h day. Patterns were labelled based on the 2-h intervals of %TEI/TPA peaks. We assessed the association between patterns and overweight or obesity (BMI z-score ≥ +1 sd) using adjusted logistic regressions (OR (95 % CI)). Three EI patterns emerged: 1 – 'Early afternoon and early evening'; 2 – 'Early afternoon and late evening'; and 3 – 'Late morning, early and mid-afternoon and late evening'. EI Pattern 3 v. Pattern 1 was negatively associated with overweight or obesity (0·49 (0·26, 0·92)). PA Pattern 1 – 'Late morning, mid-afternoon and early evening' v. Pattern 2 – 'Late afternoon', was not associated with weight status (0·95 (0·65, 1·38)). A daily EI pattern with more and even %TEI peaks at earlier daytime periods, rather than fewer and higher, may be negatively associated with overweight or obesity amongst this population whereas the identified PA patterns might have no relationship.

Background: To investigate the effect of postoperative supplementary parenteral nutrition (SPN) containing varying energy intake levels during the early postoperative period on the clinical outcomes of patients diagnosed with gastric cancer. Methods: Data from 237 patients, who were diagnosed with gastric cancer between January 2016 and June 2022, were retrospectively analyzed. Patients were divided into 2 groups based on mean daily SPN energy intake: low (L-SPN; < 20 kcal/kg/day); and high (H-SPN; ≥ 20 kcal/kg/day). Data regarding gender, age, body mass index, preoperative Nutrition Risk Screening 2002 (NRS 2002) score, American Society of Anesthesiologists Physical Status classification system, age-adjusted Charlson Comorbidity Index, diabetes, hypertension, chronic lung disease, and the Tumor-Node-Metastasis (TNM [Eighth edition]) classification were collected for propensity score matching (PSM). Postoperative indicators were monitored. A power analysis was performed during the design phase of this study to ensure that statistical power exceeded 80% to reliably detect differences between the 2 groups. Results: After PSM, data from 128 patients were analyzed (H-SPN, n = 64; L-SPN, n = 64). The H-SPN group experienced shorter postoperative hospital stay (8.11 ± 6.00 days vs. 10.38 ± 7.73 days; P = 0.045) and a lower number of infectious complications (36 [56.3%] vs. 60 [93.8%]; P < 0.001), particularly pulmonary infections, compared with the L-SPN group. Additionally, no increase in hospitalization costs or non-infectious complications occurred in the H-SPN group. Subgroup analysis revealed that H-SPN significantly reduced the incidence of infectious complications among those < 65 years of age (hazard ratio [HR] [95% confidence interval (CI) 0.240 0.069–0.829]; P = 0.024), NRS 2002 score ≥ 3 (HR 0.417 [95% CI 0.156–0.823]; P = 0.028), age-adjusted Charlson Complexity Index < 2 (HR 0.106 [95% CI 0.013–0.835]; P = 0.033), and TNM stage III (HR 0.504 [95% CI 0.224–0.921]; P = 0.046). Conclusions: H-SPN effectively reduced postoperative infectious complications and the length of hospital stay, suggesting that early postoperative H-SPN may be an advantageous nutritional support strategy for patients diagnosed with gastric cancer.

Background: Nutritional status in childhood is associated with a number of short- and long-term health effects. The rising prevalence of childhood obesity highlights the necessity of understanding dietary patterns in children. The study provides an assessment of energy and macronutrient intake and food categories' contribution to energy intake in Croatian primary school children, according to BMI status. Methods: To assess dietary habits, results of the National Food Consumption Survey on Infants and Children based on EU Menu methodology (OC/EFSA/DATA/2016/02 CT3) were used. The sample included 476 children, aged 6 to under 10 years. Results: Results indicated that one in four children was overweight or obese (27.7%). In total, the mean energy intake was 1598.4 ± 380.3 kcal/day, with 30.7% of the children above the recommended energy intake. Cereals, cereal products, and potato food category were the primary sources of energy, which is in line with the recommendations, with protein and fat intakes exceeding recommended levels. Substantial contribution of sweets and low contribution of fruits and vegetables were observed across all BMI categories, with the difference in energy contribution of fruits (p = 0.041) and vegetables (p = 0.033). The meat, poultry, fish, and eggs category were the contributors to energy intake from protein and fat, in the majority of BMI groups. Conclusions: In the obese group, higher energy intake from certain food subgroups was recorded, stressing the need for a more detailed dietary assessment. The study's cross-sectional design limits causal inferences, indicating a need for future longitudinal research to better understand the dynamics of dietary patterns and BMI status in primary school children.

The long-term impact of eating duration on the risk of all-cause mortality remains unclear, with limited exploration of how different levels of energy intake and physical activity might influence this impact. To investigate, 24 484 American adults from the National Health and Nutrition Examination Survey spanning 1999–2018 were included. Eating duration was assessed via 24-h dietary recall, and all-cause mortality data were sourced from the National Death Index. The relationship between eating duration and all-cause mortality was analysed using Cox proportional hazards regression models, restricted cubic splines and stratification analysis with complex weighted designs. The median (IQR) of eating duration for participants was 12·5 (11·0, 14·0) h. In this study, 2896 death events were observed, and the median follow-up time (IQR) was 125 (77, 177) months. After multivariable adjustment, compared with Q1, Q2, Q3 and Q4 had reduced risks of all-cause mortality by 17, 15 and 13 %, respectively. Furthermore, each additional hour of eating duration was correlated with a 2 % decrease in the risk of all-cause mortality. Additionally, a non-linear dose–response relationship was observed between eating duration and the risk of all-cause mortality, showing a U -shaped relationship from 8·9 h to 15·3 h (P for non-linearity < 0·05). Interestingly, the non-linear dose–response relationship was observed exclusively among individuals with high energy intake or a lightly active physical activity level. These findings suggest potential health benefits from adjusting eating duration, though further prospective studies are needed for validation. [ABSTRACT FROM AUTHOR]

Summary: This systematic review and meta‐analysis synthesized evidence pertaining to consummatory and appetitive responses to acute exercise in children and adolescents with and without obesity (5–18 years). Articles reporting on supervised, controlled trials of any modality, duration, or intensity with laboratory‐measured food intake were found using MEDLINE, EMBASE, and Cochrane up to July 2023. Differences between conditions in laboratory energy and macronutrient intake, appetite sensations, and food reward were quantitatively synthesized using random‐effects meta‐analyses. Thirty‐five studies were eligible for the systematic review of energy intake, consisting of 60 distinct intervention arms with lean (n = 374) and overweight/obesity participants (n = 325; k = 51 eligible for meta‐analysis). Study quality as indicated by the Effective Public Healthy Practice Project tool was rated as low and moderate risk of bias for 80% and 20% of studies, respectively. Acute exercise had no significant effect on energy intake during an ad libitum test meal (mean difference [MD] = −4.52 [−30.58, 21.54] kcal, p =.729). Whilst absolute carbohydrate intake was lower after exercise (23 arms; MD = −6.08 [−11.26, −0.91] g, p =.023), the proportion of carbohydrate was not (30 arms; MD = −0.62 [−3.36, 2.12] %, p =.647). A small elevation in hunger (27 arms; MD = 4.56 [0.75, 8.37] mm, p =.021) and prospective food consumption (27 arms; PFC; MD = 5.71 [1.62, 9.80] mm, p =.008) was observed post‐exercise, but not immediately prior to the test meal (Interval: Mdn = 30 min, Range = 0–180). Conversely, a modest decrease in explicit wanting for high‐fat foods was evident after exercise (10 arms; MD = −2.22 [−3.96, −0.47] mm, p =.019). Exercise intensity (p =.033) and duration (p =.013) moderated food intake only in youth with overweight/obesity, indicating lower intake at high intensity and short duration. Overall, acute exercise does not lead to compensation of energy intake or a meaningful elevation of appetite or food reward and might have a modest benefit in youth with overweight/obesity if sufficiently intense. However, conclusions are limited by substantial methodological heterogeneity and the small number of trials employing high‐intensity exercise, especially in youth with overweight/obesity.

Introduction: Resting energy expenditure (REE) may fluctuate during the menstrual cycle (MC), due to the physiological effects of estradiol (E2) and progesterone. This study examined changes in REE and metabolic hormones (leptin, ghrelin, thyroid hormones), and dietary intake in two hormonally distinct groups, naturally menstruating women (NoOC) and women using monophasic combined oral contraceptives (COC). Methods: Measurements included REE by indirect calorimetry, body composition by bioimpedance, and blood samples for hormone analysis in the early follicular and midluteal phases of the MC in the NoOC group (n = 38) or the active and inactive phases of the COC cycle (COC; n = 19). Participants recorded their food intake for 3 d after measurements. A secondary analysis was completed for the NoOC group without REE outliers (difference between measurements >1.5 × interquartile range, n = 4). Results: In the NoOC group, luteal phase REE was 40 kcal higher than follicular phase REE (95% confidence interval (CI), −2 to 82 kcal·d−1, d = 0.20, P = 0.061). Leptin (d = 0.35, P < 0.001), triiodothyronine (T3; d = 0.26, P = 0.05), and fat intake (d = 0.48, P = 0.027) were higher, and thyroxine (d = 0.21, P = 0.041) was lower in the luteal phase. After excluding outliers, REE was 44 kcal higher in the luteal phase than in the follicular phase (95% CI, 12–76 kcal·d−1, d = 0.22, P = 0.007). In the COC group, the mean difference in REE was −2 kcal (95% CI, −82 to 79 kcal·d−1) between active and inactive phases, whereas T3 was higher in the inactive phase (d = 0.01, P = 0.037). Conclusions: REE increases only slightly from the follicular to the luteal phase but remains unchanged between COC phases. Increases in T3, leptin, and fat intake during the luteal phase might echo metabolic fluctuations that parallel female sex hormones during the MC. [ABSTRACT FROM AUTHOR]

Learning in the mountains during winter prepares upcoming guides for tough environments by placing demands on their energy intake and enabling them to cope with a complex environment. However, few studies have explored energy intake and expenditure in outdoor education. Thus, energy intake during a 24-hour winter mountain course was investigated in a Norwegian educational context, where students must absorb large volumes of information in a challenging environment. Twenty university students (11 men, 9 women) underwent body composition, weighed energy intake, and accelerometry-based energy expenditure measurements. Overall, the students had an energy deficit of>2,300 kilocalories/day, corresponding to an energy balance of 62% for men and 54% for women (p > 0.05), despite having received lectures on energy requirements in advance. This sustained stress context combined with challenging environmental conditions and insufficient energy intake can predispose students to early exhaustion, injury risk, and potentially reduced information processing that may limit learning.

This publication presents a study of the existing computational and laboratory methods for studying the energy expenditure of the human organism, as well as the methods for determining energy intake. The article also specifies the most appropriate methods for determining the energy expenditure and energy intake of military personnel when they are placed in field conditions during their training. A universal methodology for measuring the energy consumption of military personnel during their training and combat activities is also presented. [ABSTRACT FROM AUTHOR]

Abstract Background To investigate the effect of postoperative supplementary parenteral nutrition (SPN) containing varying energy intake levels during the early postoperative period on the clinical outcomes of patients diagnosed with gastric cancer. Methods Data from 237 patients, who were diagnosed with gastric cancer between January 2016 and June 2022, were retrospectively analyzed. Patients were divided into 2 groups based on mean daily SPN energy intake: low (L-SPN; < 20 kcal/kg/day); and high (H-SPN; ≥ 20 kcal/kg/day). Data regarding gender, age, body mass index, preoperative Nutrition Risk Screening 2002 (NRS 2002) score, American Society of Anesthesiologists Physical Status classification system, age-adjusted Charlson Comorbidity Index, diabetes, hypertension, chronic lung disease, and the Tumor-Node-Metastasis (TNM [Eighth edition]) classification were collected for propensity score matching (PSM). Postoperative indicators were monitored. A power analysis was performed during the design phase of this study to ensure that statistical power exceeded 80% to reliably detect differences between the 2 groups. Results After PSM, data from 128 patients were analyzed (H-SPN, n = 64; L-SPN, n = 64). The H-SPN group experienced shorter postoperative hospital stay (8.11 ± 6.00 days vs. 10.38 ± 7.73 days; P = 0.045) and a lower number of infectious complications (36 [56.3%] vs. 60 [93.8%]; P

Calorie restriction (CR) with adequate nutrient intake is a potential geroprotective intervention. To advance this concept in humans, we tested the hypothesis that moderate CR in healthy young-to-middle-aged individuals would reduce circulating biomarkers of cellular senescence, a fundamental mechanism of aging and aging-related conditions. Using plasma specimens from the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE™) phase 2 study, we found that CR significantly reduced the concentrations of several senescence biomarkers at 12 and 24 months compared to an ad libitum diet. Using machine learning, changes in biomarker concentrations emerged as important predictors of the change in HOMA-IR and insulin sensitivity index at 12 and 24 months, and the change in resting metabolic rate residual at 12 months. Finally, using adipose tissue RNA-sequencing data from a subset of participants, we observed a significant reduction in a senescence-focused gene set in response to CR at both 12 and 24 months compared to baseline. Our results advance the understanding of the effects of CR in humans and further support a link between cellular senescence and metabolic health.

A mechanistic, dynamic model was developed to calculate body composition in growing lambs by calculating heat production (HP) internally from energy transactions within the body. The model has a fat pool (f) and three protein pools: visceral (v), nonvisceral (m), and wool (w). Heat production is calculated as the sum of fasting heat production, heat of product formation (HrE), and heat associated with feeding (HAF). Fasting heat production is represented as a function of visceral and nonvisceral protein mass. Heat associated with feeding (HAF) is calculated as ((1 - km) x MEI), where km is partial efficiency of ME use for maintenance, and MEI = metabolizable energy intake) applies at all levels above and below maintenance. The value of km derived from data where lambs were fed above maintenance was 0.7. Protein change (dp/dt) is the sum of change in the m, v, and w pools, and change in fat is equal to net energy available for gain minus dp/dt. Heat associated with a change in body composition (HrE) is calculated from the change in protein and fat with estimated partial efficiencies of energy use of 0.4 and 0.7 for protein and fat, respectively. The model allows for individuals to gain protein while losing fat or vice versa. When evaluated with independent data, the model performed better than the current Australian feeding standards (Freer et al., 2007) for predicting protein gain in the empty body but did not perform as well as for gain of fat and fleece-free empty body weight. Models performed similarly for predicting clean wool growth. By explicit representation of the major energy using processes in the body, and through simplification of the way body composition is computed in growing animals, the model is more transparent than current feeding systems while achieving similar performance. An advantage of this approach is that the model has the potential for wider applicability across different growth trajectories and can explicitly account for the effects of systematic changes on energy transactions, such as the effects of selective breeding, growth manipulation, or environmental changes.

Context The melanocortin-4 receptor gene (MC4R) is associated with a higher risk of obesity by the presence of the C allele in rs17782313, but the mechanisms are not clear. Objective The present systematic review and meta-analysis aimed to explore the association between the different genotypes of MC4R rs17782313 and energy intake and appetite. Data Sources A literature search was conducted up to June 2023 in PubMed, Scopus, Web of Science, and Cochrane Collaboration databases, following PRISMA guidelines. Data Extraction Inclusion criteria were studies in humans measuring energy intake, appetite, or satiety in all ages and physiological conditions. Studies dealing solely with body mass index were excluded. Twenty-one articles representing 48 560 participants were included in the meta-analysis. Data Analysis According to the NHLBI (National Heart, Lung, and Blood Institute) quality-assessment criteria, all case-control studies and 6 out of 17 cohort and cross-sectional studies were classified as "good," while the rest scored as "fair." Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated in a (CT+CC) vs TT dominant model, and both random-effects and fixed-effects models were used. A statistically significant association between the presence of the C allele and increased appetite was found (OR = 1.25; 95% CI: 1.01–1.49; P = .038) using the fixed-effects model, but the random-effects model proved nonsignificant. However, no association with energy intake was found. None of the variables considered (sample size, year of publication, sex, age group, type of population, origin, and quality) were identified as effect modifiers, and no publication biases were found after subgroup and meta-regression analyses. Conclusion To our knowledge, this is the first systematic review and meta-analysis that has analyzed the association between rs17782313 of MC4R and energy intake and appetite. Identifying people genetically predisposed to increased appetite may be of great interest, not only to prevent obesity in younger populations but also to avoid malnutrition in elderly persons.

Purpose: With ageing, older adults (≥ 65 years) may experience decreased appetite, contributing to declines in body weight and muscle mass, potentially affecting physical capabilities. Physical activity (PA) has been suggested as a potential strategy to enhance appetite in older adults, but evidence supporting this is insufficient. This study aimed to investigate the relationship between PA levels, total energy expenditure (TEE), body composition, energy intake (EI) and appetite in older adults. Methods: One hundred and eight healthy older adults (age 70 ± 4 years; BMI 24.3 ± 2.6 kg/m2) were categorised into three groups (low, medium, high) based on accelerometer-measured PA level (AMPA) and TEE from 7-day PA diaries. Body composition was measured using bioelectrical impedance. Energy and nutrient intakes were assessed using 3-day weighed food diaries. Appetite was assessed using the visual analogue scales at 30-min intervals throughout 1 day. Results: TEE was positively correlated with EI and % muscle mass (p < 0.05), with higher % muscle mass and TEE associated with higher EI. Energy and protein intake were significantly higher in the high TEE group than the low group (p = 0.03, p = 0.01; respectively). No significant differences in energy and macronutrient intake were observed across AMPA groups, and appetite components (hunger, fullness, desire to eat, prospective consumption) did not differ significantly in either the AMPA or TEE groups. Conclusions: Higher TEE is associated with higher energy and protein intake, with body composition playing a crucial role. These findings highlight the importance of considering PA, TEE, and body composition in interventions aimed at improving EI in older adults.

Background: This study aimed to characterize the relationship between habitual food intake and OSA. Methods: The diet of 200 volunteers was evaluated using a Food Frequency Questionnaire. The patients were further allocated to mild, moderate, and severe OSA groups. The relationships of OSA with diet were evaluated using multivariate linear regression analysis and the relationships of the energy supply ratio for three major nutrients and demand with sleep parameters were assessed using correlation analysis. Results: The analysis of nutrient intake showed a reduced energy intake in non-OSA patients (11953.98 ± 7578.11 kJ, 95% CI 9677.27–14230.70 kJ) as compared to severe-OSA patients (15153.43 ± 6541.89 kJ, 95% CI 13678.46–16628.40 kJ) (p < 0.05). Similarly, lower intake of carbohydrates was observed in non-OSA (249.94 ± 134.96 g/day, 95% CI 209.39–290.48 g/day) as compared to severe OSA patients (348.57 ± 112.34 g/day, 95% CI 323.24–373.90 g/day) (p < 0.05). Compared with participants without OSA, we found that those with OSA had significantly poorer diets, with higher contents of rice (β = 0.195, p = 0.006), wheat (β = 0.236, p = 0.001), stuffed food items (β = 0.278, p < 0.001), fried food (β = 0.193, p = 0.006), dairy products (β = 0.198, p = 0.005), and sweet beverages (β = 0.154, p = 0.030). After adjustment for age, sex, the presence of diabetes, and waist-hip ratio, these relationships remained. Furthermore, a higher proportion of energy intake in the form of carbohydrate was associated with more severe OSA. Conclusion: The severity of OSA is related to the level of carbohydrate consumption. Poor dietary habits predispose toward body mass gain and a worsening of sleep-related parameters, which may accelerate the pathogenesis of OSA. [ABSTRACT FROM AUTHOR]

Background Early-life food consumption patterns may affect children’s health by increasing susceptibility to developing non-communicable chronic diseases (NCDs) in adulthood. Aims To evaluate Jordanian children and adolescents’ energy and macronutrient intake and how closely they adhere to dietary recommendations. Methods This cross-sectional study used data from Jordan’s Population-based Food Consumption Survey, a household population-based study conducted in Jordan between 2021 and 2022 (561 children and adolescents 8-19 years). Dietary intake was assessed using the two non-consecutive 24-hour dietary recall methods (24-h DR). The estimated food group and nutrient intakes were compared to nutritional recommendations, including MyPlate dietary guidelines. Results The prevalence of overweight/obese individuals based on body mass index (BMI) was 44%, and the average waist-to-height ratio (WHtR) was 24.7%. Compared to MyPlate dietary guidelines, children and adolescents had a higher added sugar intake (57g/day). Also, consuming vegetables, fruits, and dairy fell short of MyPlate dietary guidelines. The total discretionary calorie intake in children and adolescents was approximately one-third of the total energy intake. Conclusion The food consumption of Jordanian children and adolescents includes high intakes of discretionary calories, with a low intake of fruits, vegetables, and dairy products. The prevalence of overweight/obesity was elevated compared to international norms.

Aims: To assess test–retest reliability of both food photography and food diary methods and validity of these data against known values derived from food labels. Methods: Test–retest reliability analyses of food diary and food photography were compared using single foodstuffs using intra‐class correlation coefficients, coefficients of variation, and limits of agreement. For food diaries, 24‐h test–retest reliability was also examined. Validity was assessed against weighed analyses. As part of habitual intake, a single foodstuff (randomly allocated from 14 common foods) was consumed by 26 participants over 24‐h. On two occasions (14 days apart), single‐blind dietary analyses allowed estimation of foodstuff‐specific energy and macronutrient content and 24‐h intakes. Results: For food diaries, test–retest reliability was acceptable (weight, energy, carbohydrate, protein, and fat: all intra‐class correlation coefficients: >0.990, coefficient of variation percentage: <0.1%, limits of agreements: <0.1 to <0.1, p > 0.05, and effect size: <0.01). For food photography, test–retest reliability was acceptable for weight, energy, carbohydrate, and protein (all intra‐class correlation coefficients: >0.898, coefficient of variation percentage: 3.6%–6.2%, limits of agreements: 1.1 to – 44.9, and effect size: 0.01–0.12). Food photography validity was worse than food diaries for all variables (percentage difference: 8.8%–15.3%, coefficient of variation percentage: 7.5%–13.8%, all p ≤ 0.05, and effect size: 0.001–0.11). Conclusions: Greater reliability and validity occurred in food diaries versus food photography. These findings suggest that using food photography may lead to an underestimation of energy and macronutrient content, which may have implications for dietary interventions and nutritional strategies.

• Accurate nutrient content estimation is key for adhering to dietary guidelines. • Sugar content is often misestimated, potentially due to estimations in grams. • This experiment tests the impact of the estimation measure (grams vs sugar cubes). • Data from a large cohort study is used. • Sugar content is vastly overestimated, yet more so when estimated in grams. • More intuitive cues for healthy food choices are required. To make healthy food choices, consumers need to be aware of the sugar content of foods. Units act as an environmental cue that might influence sugar content estimation accuracy. The present study (1) tested whether estimations of sugar content are more accurate in sugar cubes vs grams, (2) compared accuracy of sugar content to estimations of the foods' weight and energy content, and (3) investigated gender, education, and body mass index as potential correlates. A sample of 886 adults was randomly assigned to estimating the sugar content of 10 common foods in grams or cubes. Estimations of sugar content diverged considerably from actual values in both groups (0.22 ≤ Cohen's d s gram s ≤ 1.20; 0.20 ≤ Cohen's d s cubes ≤ 1.10), but were more pronounced for sugar content estimations in grams in 7 out of 10 foods (t s ≥ 4.04, P s <.001, Cohen's d s ≥ 0.14). Sugar content misestimation was somewhat more pronounced than misestimation of weight (0.05 ≤ Cohen's d s ≤ 1.43) and energy content (0.04 ≤ Cohen's d s ≤ 1.19). Relationships between sugar content misestimation and gender (0.00 ≤ Cohen's d s ≤ 0.33), education (–0.07 ≤ r ≤ 0.11), and body mass index (–0.08 ≤ r ≤ 0.06) were mostly negligible. Although sugar content estimations were somewhat more accurate in sugar cubes vs grams, estimation accuracy is generally low. In addition to promoting consumers' knowledge through labeling and education, additional avenues for interventions might need to be explored for sizeable effects on food choices. This study tested if sugar content estimation is more accurate in sugar cubes vs grams in a sample of 886 adults, who estimated the sugar content of 10 common foods. Sugar content was largely overestimated in both groups, but more so in grams for 7 of 10 foods. Relationships between misestimation and gender, education, and body mass index were negligible. Although estimations were somewhat more accurate in sugar cubes, accuracy is generally low, so cues are needed that rely less on knowledge. [Display omitted] [ABSTRACT FROM AUTHOR]

Summary: Numerous investigations have studied relationships between satiation, satiety, or food intake and single factors like food composition and resting metabolic rate. However, a comprehensive framework connecting food, physiological, and psychological factors together has not previously been reported. As an exploratory study with a trained panel consisting of nine participants, the contributions of twenty‐eight variables (seven food, seven psychological, and fourteen physiological factors) to satiation, satiety, and food intake of a mid‐morning snack were investigated. Both human factors and foods had contributions to perceived satiation and satiety, but with large differences in loadings, especially for metabolic factors. Food factors, including nutrient and energy contents, were major determinants of food intake, with only small contributions from human factors. Investigating diverse factors together provides a comprehensive approach linking appetite to both food and human factors. This study suggests the potential to guide manipulation of satiation, satiety, and food intake depending on individual psychological and physiological profiles. [ABSTRACT FROM AUTHOR]

Low energy availability (LEA) is a present risk for many female athletes. Yet, the literature on LEA is often reliant on single, short-term, snapshots, which may not be reflective of the chronic energy balance surrounding female athletes in sport. Therefore, the purpose of this study was to establish the current prevalence of LEA in female collegiate beach volleyball athletes during the preseason and across the competitive season. One-way repeated measures analysis of variance was used to compare measures of EA (i.e., dietary intake, activity energy expenditure [EE], body composition) and EE (i.e., resting metabolic rate and thermic effect of feeding) at 4 timepoints--once in the preseason (i.e., Fall), and 3 times across the 10-week competitive season in Spring (i.e., week 1, week 5, and week 9). Significance was set at p#0.05. Although mean EA was in the subclinical zone (i.e., 30-45 kcal·kg FFM21·d21) at each timepoint, the prevalence of LEA for individuals was 30.8% in the preseason, 37.5% at week 1, 25.0% at week 5, and 62.5% at week 9. Further, carbohydrate intake was below the recommended range for power athletes at each timepoint, suggesting that female beach volleyball athletes with LEA may benefit from increasing carbohydrate intake. Despite no statistical differences in body mass across the season (p50.577), there was a trend for increasing fat-free mass (p50.062) as the season progressed. Importantly, LEA is not a team-wide condition but an individual one. Therefore, approaches to mitigate LEA should be individualized. [ABSTRACT FROM AUTHOR]

Background: Adequate energy intake is essential for good clinical outcomes. The association between energy intake and readmission burden of patients with heart failure (HF) still needs to be clarified. Objective: In this study, our aim was to determine the association between energy intake and readmission in patients with HF. Methods: A total of 311 inpatientswith HF were recruited. Demographic and clinical information were collected during hospitalization; the daily diets of the participants were collected in the second week after discharge using the 3-day diet record, and the energy intake was calculated using a standardized nutrition calculator. The inadequate energy intake was defined as <70% x 25 kcal/kg of ideal body weight. The participantswere followed up for 12weeks after discharge. The number, reasons, and length of stay of unplanned readmissions were collected. Regression analyses were used to evaluate the associations between inadequate energy intake, and readmission rate and readmission days. Results: The median of the energy intake of participantswas 1032 (interquartile range, 809-1266) kcal/d. The prevalence of inadequate energy intakewas 40%. Patientswith inadequate energy intake had a higher risk of unplanned readmission (odds ratio, 5.616; 95% confidence interval, 3.015-10.462; P < .001) and more readmission days (incidence rate ratio, 5.226; 95% confidence interval, 3.829-7.134, P < .001) after adjusting for potential confounders. Conclusions: Patients with HF had a high incidence of inadequate dietary energy intake, and it increases the burden of readmission. [ABSTRACT FROM AUTHOR]

Maternal nutritional needs increase during lactation. However, the energy intake of breastfeeding mothers usually still falls short of the recommended adequacy levels. This study aimed to identify the dominant factor of energy intake in breastfeeding mothers in Sawangan District, Depok City, Indonesia. This quantitative study used a cross-sectional design from July 2022 to February 2023. Energy intake, dietary diversity, and eating frequency were collected using 24-hour food recall. Other variables were collected through interviews with structured questionnaires. Data were analyzed using the Chi-square test and binary logistic regression. A total of 217 breastfeeding mothers participated in this study. This study found that 78.3% of breastfeeding mothers had inadequate energy intake. Dietary diversity (p-value = 0.032) was the dominant factor associated with the energy intake of breastfeeding mothers. Breastfeeding mothers with non-diverse food consumption were at a 2.507 times higher risk of inadequate energy intake. Energy intake in breastfeeding mothers is related to the sustainability of breastfeeding. However, most breastfeeding mothers in Sawangan District still have insufficient energy intake. Therefore, it is suggested that food supplementation for breastfeeding mothers should be included in promoting exclusive breastfeeding. [ABSTRACT FROM AUTHOR]

Eating behaviors develop in early life and refine during childhood, shaping long-term food choice and dietary habits, which underpin optimum growth and health. The development of Food Oral Processing (FOP) is of major importance in the establishment of eating behaviors at two scale levels: for the initial acceptance of food texture and for the longer-term development of eating behaviors associated to food intake. To date, both processes have been studied as independent topics and the current review proposes a parallel vision on their development from the onset of complementary feeding to later childhood. Individual factors affecting these FOP-related behaviors as they relate to food texture acceptance are discussed, alongside examples of interventions aiming at modifying them. Opportunity to better consider food textures when designing foods for children is addressed. Altogether, the review demonstrates the critical role of food texture in the development of a child's FOP skills, eating habits, and dietary patterns. These scientific knowledges need to be considered for the development of healthier eating behavior. We identify research gaps that need to be addressed and highlight the need to design foods that can support the development of healthy oral processing and eating behaviors among infants and children.

Background/Objectives: Energy availability (EA) is essential for maintaining physiological functions, significantly influencing athletes' health and performance. Nutritional behaviors, however, vary across sports. This study aims to assess EA levels in athletes from different disciplines, focusing on the relationship between EA and body composition in endurance athletes compared to rugby players. Methods: This study involved 18 endurance athletes (15 men, 3 women) and 36 rugby players (all men). Data were gathered through interviews, questionnaires, and bioimpedance analysis. Energy intake (EI) was measured with a 24 h dietary recall, and exercise energy expenditure (EEE) was calculated using the IPAQ questionnaire. EA was calculated as EA = (EI − EEE)/fat-free mass (FFM), with results categorized into clinical, subclinical, and optimal ranges. Results: The endurance group had a lower average FFM (57.81 kg) compared to the rugby players (67.61 kg). EA was also significantly lower in endurance athletes (11.72 kcal/kg FFM) than in rugby players (35.44 kcal/kg FFM). Endurance athletes showed more restrictive nutritional behavior with lower EI and higher EEE, but both groups maintained body composition within normal ranges. Conclusions: Endurance athletes exhibit greater nutritional restrictions compared to rugby players, though their body composition remains healthy. Further research is required to investigate the long-term effects of low EA on performance, injury risk, and potential impairment when EA falls below the optimal threshold of 45 kcal/kg FFM/day.

Background and objective: Tools to accurately and efficiently measure dietary intake in Nigeria are lacking. We aimed to develop and assess the usability of a new online dietary assessment tool for Nigeria—myfood24 West Africa. Methods: We developed the myfood24 West Africa database using data from existing food composition tables, packaged foods labels and research articles. The development followed seven steps: identified data sources, selected foods, processed/cleaned the data, calculated the nutrient content of recipes, created and allocated portion sizes, quality-checked the database and developed food accompaniments. To pilot the tool, we recruited 179 university staff in Nigeria using a cross-sectional design. Usability was assessed using a questionnaire that included the System Usability Scale (SUS) and a feedback session. Results: The database included 924 foods, with up to 54 nutrients and 35 portion-size images allocated to foods. Sixty percent of the data were sourced from the 2019 West Africa Food Composition Table, 17% from back-of-pack labels of packaged foods, 14% from the 2017 Nigerian Food Composition Table, 5% from generated recipes and 4% from the published literature. Of the participants, 30% (n = 53) self-recorded their food intake, with a total of 1345 food and drink entries from both self- and interviewer-collected data. The mean SUS score of 74 (95% CI: 68,79) indicated good usability. The feedback showed that the tool was user-friendly, educational and included a variety of local foods. Conclusions: This new tool will enhance the dietary assessment of the Nigerian population. More work will expand coverage to include more foods from the region. [ABSTRACT FROM AUTHOR]

Summary: Our understanding of the pathophysiology of obesity remains at best incomplete despite a century of research. During this time, two alternative perspectives have helped shape thinking about the etiology of the disorder. The currently prevailing view holds that excessive fat accumulation results because energy intake exceeds energy expenditure, with excessive food consumption being the primary cause of the imbalance. The other perspective attributes the initiating cause of obesity to intrinsic metabolic defects that shift fuel partitioning from pathways for mobilization and oxidation to those for synthesis and storage. The resulting reduction in fuel oxidation and trapping of energy in adipose tissue drives a compensatory increase in energy intake and, under some conditions, a decrease in expenditure. This theory of obesity pathogenesis has historically garnered relatively less attention despite its pedigree. Here, we present an updated comprehensive formulation of the fuel partitioning theory, focused on evidence gathered over the last 80 years from major animal models of obesity showing a redirection of fuel fluxes from oxidation to storage and accumulation of excess body fat with energy intake equal to or even less than that of lean animals. The aim is to inform current discussions about the etiology of obesity and by so doing, help lay new foundations for the design of more efficacious approaches to obesity research, treatment and prevention.

Peru is one of the most diverse countries in the world in terms of food production, but also suffers a wide range of food security challenges, including malnutrition, the impact of natural hazards, and rising food prices. People living in poverty conditions are the main victims of these problems, which trigger undernutrition, obesity, and diet‐related non‐transmittable diseases. Despite these challenges, Peru lacks historical food intake data. Therefore, in the current study, we assess the diet quality evolution in the period 2008–2021 based on apparent household purchases extracted from the National Household Survey. The results reveal significant variations in the consumption of certain food items and groups, and the consequences of these changes are discussed in environmental and human health terms. The consumption of lower environmental impact animal protein, such as chicken, eggs, and marine fish, has increased by 37%, 69%, and 29%, respectively; whereas the consumption of high environmental impact foods, such as beef and other red meat, has decreased. Moreover, consumption of less processed carbohydrate sources (e.g., legumes, fruits, and vegetables) has risen, while refined sugar and sugar‐sweetened beverages have decreased significantly (almost 45%). Regional differences were also visible; hence, cities on the Northern coast and the Amazon basin had similar consumption habits, whereas Central/Southern coastal and Andean cities had closer consumption patterns. On average, this improvement was reflected in the increase in calories (9.9%) and macronutrient intake (up to 15%), but at the socioeconomic level, food inequality persists, with consumption of many food groups below minimum thresholds in lower socioeconomic strata.
