Anticipatory and consummatory pleasure in eating disorders

Plain English summary Anhedonia, or the inability to experience pleasure, has been observed in individuals with eating disorders. Neuroscience research suggests that pleasure may be separated into two distinct components: anticipatory pleasure (how much someone predicts they will enjoy a future experience) and consummatory pleasure (how much someone enjoys a present experience). In the current study, individuals with eating disorders and healthy controls completed questionnaires assessing anticipatory and consummatory pleasure, binge eating, other eating disorder behaviors, depression, anxiety, and constructs associated with reward and punishment sensitivity. The sample with eating disorders reported significantly lower anticipatory but not consummatory pleasure than the control sample. Within the eating disorder sample, greater anticipatory pleasure was also related to higher binge eating frequency but lower depression, anxiety, and weight and shape concerns. These results suggest that anticipatory pleasure may be particularly important in future research on the etiology and treatment of eating disorders.
