Weight-loss history as a predictor of obesity treatment outcome

Weight-loss history as a predictor of obesity treatment outcome: prospective, long-term results from behavioral, group self-help treatment.
OBJECTIVE: Weight-loss history was examined as a predictor of outcome in group self-help obesity treatment.

METHODS: Participants (n = 128; 83% women; mean body mass index = 34.2 kg/m(2); mean age = 47.2 years) in self-help, group behavioral weight-loss treatment reported a mean of 5.1 prior weight-loss attempts and lost 13.8 percent of initial weight in current treatment.

RESULTS: A greater number of past attempts independently predicted greater 6-month, 18-month, and intent-to-treat weight losses. Greater magnitude of largest past loss predicted greater 18-month weight loss. 

CONCLUSION: In contrast to studies on professional treatment, group self-help participants might benefit from repeated weight-loss efforts despite previous failures.
