Exercise augments the effects of cognitive-behavioral therapy in the treatment of binge eating

Objective: To evaluate the effects of adding exercise and maintenance to cognitive-behavior therapy (CBT) for binge eating disorder (BED) in obese women. Method: One hundred fourteen obese female binge eaters were randomized into four groups: CBT with exercise and maintenance, CBT with exercise, CBT with maintenance, and CBT only. Results and Discussion: Eighty-four women completed the 16-month study. Subjects who received CBT with exercise experienced significant reductions in binge eating frequency compared with subjects who received CBT only. The CBT with exercise and maintenance group had a 58% abstinence rate at the end of the study period and an average reduction of 2.2 body mass index (BMI) units (approximately 14 Ib). BMI was significantly reduced in the subjects in both the exercise and maintenance conditions. The results suggest that adding exercise to CBT, and extending the duration of treatment, enhances outcome and contributes to reductions in binge eating and BMI. (C) 2002 by Wiley Periodicals, Inc.
