Responses to weight loss treatment among obese individuals with and without BED: A matched-study meta-analysis
The moderating influence of binge eating status on obese individuals’ responses to weight loss treatment was evaluated with a meta-analysis of 36 tests of weight loss treatment (n=792) that were matched to control key background variables. After controlling for pre-treatment weight, treatment produced more weight loss in samples of obese non-BED compared with obese BED participants. Weight loss treatment produced large posttreatment reductions in depression in both obese BED and non-BED samples. The results indicate that BED status moderated post-treatment weight loss among people in weight treatment programs. Obese BED (average weight loss= 1.3 kg) samples lost negligible weight compared to obese non-BED (average weight loss= 10.5 kg) samples. BED status did not moderate psychological responses to treatment: both BED and non-BED samples experienced large post-treatment reductions in depression. The clinical implications of these findings are discussed.
