Background and Purpose: Depression and binge eating are common adverse psychologic responses associated with weight loss in overweight and obese adults. This study aimed to assess the effects of different degrees of weight loss on psychologic functioning and the relationship between mood change and weight reduction, and to identify predictors of short-term weight loss among subjects in a hospital-based weight reduction program. Methods: A total of 189 obese subjects who participated in a hospital-based weight-reduction program during a 12-week interval were enrolled in this study. They ranged in age from 18 to 67 years (mean, 40.5 ± 12.3 yr) with female predominance (87.8%). Mean body weight was 79.3 13.9 kg and mean body mass index was 31.1 ± 3.8 kg/m2 on entry into the program. Body weight was periodically measured and subjects were asked to complete two self-administered questionnaires including the Brief Symptom Rating Scale (BSRS) and the Bulimic Investigatory Test, Edinburgh (BITE), pre- and post-treatment. Results: Using the last observation carried forward method of analysis, the average weight loss for all participants was 5.6 ± 3.7 kg. For subjects who completed the 12-week program, weight loss was 6.6 ± 3.6 kg. Subjects who completed the program (n = 115, 60.8%) had significantly reduced BITE as well as BSRS subscale scores at the end of the program. There was no linear relationship between mood change and weight loss by correlation analysis, but subjects with higher degrees of weight loss had improvement in more dimensions of psychologic functioning. Initial mood and binge-eating status predicted neither compliance nor weight reduction. Two biologic factors (initial weight loss, initial body weight) and one behavioral factor (attendance rate) were identified as significant predictors of short-term weight loss for all subjects. Conclusions: There was no evidence that weight loss made mood or eating pathology worse among those who completed the weight loss program. Beneficial effects on general psychologic functioning and eating pathology were demonstrated for subjects with a minimal weight loss of 5% of initial weight and who completed the program. Psychologic assessments at the start of the program did not predict weight loss at the end of participation in this hospital-based weight loss program.
