Abstract
Objective. Binge eating disorder (BED) is highly comorbid with obesity, making weight loss an important goal. Yet, findings from behavioral weight loss (BWL) interventions including participants with and without BED are mixed. The present meta-analysis compared weight loss outcomes of individuals with and without BED in BWL interventions, while controlling for variables that could influence weight loss outcomes. Weight regain and dropout rates between groups were also examined, as well as the effect of BED diagnostic category on outcomes. Methods. Electronic search engines were searched for relevant manuscripts published up to May 2017 using terms related to weight loss treatment and binge eating disorder. Twenty-eight manuscripts (full-threshold BED N = 1,333; non-BED N = 6,336; sub-threshold BED N = 251) were deemed eligible for inclusion. Results. A meta-regression found that individuals with full-threshold BED achieved lower weight loss (by approximately 2.3 kg) when key covariates were controlled for. A random effects model showed that a full-threshold BED diagnosis increased the odds of treatment dropout by 50%. Meta-regression models found no effect of full-threshold BED condition on weight regain, or BED diagnostic category on weight loss. Conclusions. Overall, individuals with full-threshold BED, compared to those without BED, lost less weight in BWL interventions and their odds of dropping out of treatment were increased by 50%. Future research should consider examining BED diagnosis as a moderator of treatment outcome in BWL interventions, and aim to close the gap in weight loss outcomes and retention rates between those with and without full-threshold BED.
