Improving Weight Loss Outcomes for Binge Eating Disorder.

Improving Weight Loss Outcomes for Binge Eating Disorder.

This study aims to develop and evaluate the efficacy of a behavioral weight loss treatment approach for individuals with binge eating disorder to both reduce their binge eating behaviors and lose weight.

In the current study, we propose to (a) compare the efficacy of an acceptance-based behavioral treatment (ABBT) that targets both binge eating and weight loss in patients with binge eating disorder (BED) to a Standard Behavioral Weight Loss Treatment (SBT), (b) evaluate the extent to which ABBT and SBT target shared maintenance factors for binge eating and overeating episodes, and (c) assess whether treatment efficacy is moderated by baseline values of constructs targeted in ABBT. Our study will be the first to evaluate an ABBT for BED designed to 1) address maintenance factors that give rise to both binge eating episodes and overeating episodes without loss of control and 2) increase adherence to BWL prescriptions.
