The present study compared the outcome of bariatric surgery against a uniform high-level weightloss program which included vigorous physical exercises, behavior modification and nutritional advice. 44 subjects who underwent bariatric surgery and 47 subjects participating in a weight-loss program completed the Medical Outcomes Study Short Form- 36 (SF-36), the Mental Health Inventory (MHI) and the Rosenberg Self-Esteem scale, prior to surgery/diet and one year afterwards. Post-surgery subjects had a greater mean weight loss (34.70% ± 11.94) than subjects in the weight-loss program, even though their weight reduction was also clinically significant (9.23% ± 8.31). Post-surgery subjects showed significant improvements in SF-36, MHI, and selfesteem. The diet group improved in SF-36 total score, physical functioning, health perceptions, and vitality scales. Differences in background variables and short follow-up. Surgery outcomes were significantly better in terms of both weight reduction and psychological adjustment compared to highly motivated participants in a prestigious, cutting edge weight-loss program.
