Feeding and eating disorders (FEDs) are a heterogeneous grouping of disorders at the mind-body interface, with typical onset from childhood into emerging adulthood. They occur along a spectrum of disordered eating and compensatory weight management behaviors, and from low to high body weight. Psychiatric comorbidities are the norm.

The ability of the gastrointestinal tract to harvest and utilize energy from food is essential for successful weight restoration, but the functional capacity of the intestine after prolonged caloric restriction remains unknown. In an exploratory study, we quantified the stool energy content of individuals with AN before and after renourishment.

While up to 40% of patients may experience loss of control (LOC) eating following MBS, mechanisms driving this behavior are not fully understood. Preliminary evidence suggests that high levels of negative affect (NA) in the moment prompt LOC eating post-MBS; however, it remains unclear whether this momentary relationship is stable or changes over the first several years following surgery.
View Article and Find Full Text PDFAffect 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.
