The aim of this study was to evaluate differences in body mass index and eating behavior in obese and overweight persons with and without anhedonia during a weight loss intervention study. Psychiatric diagnostics were based on the Structured Clinical Interview for DSM-IV disorders. Eating behavior was assessed by the Three Factor Eating Questionnaire (TFEQ-18) and binge eating by the Binge Eating Scale (BES). Out of 82 participants, 20 (24.4%) reported experiencing anhedonia at least once during the study period. Those suffering from anhedonia scored significantly higher values in BES at baseline and at follow-up. They also reported more uncontrolled and emotional eating at the first follow-up. Overall, persons suffering from anhedonia achieved a poorer outcome in weight loss compared to those without anhedonia. Anhedonia was associated with uncontrolled eating, emotional eating, and binge eating, all of which may have contributed to the poorer outcomes achieved in weight loss. (C) 2010 Elsevier Ltd.
