Weight loss: long-term results in an ambulatory setting.

Maintenance of weight loss is an issue of interest to the dietetic practitioner. A series of 12 weight-loss classes was conducted using the behavioral approach. Mean weight loss of 11.1 lb. in this study compared favorably with weight losses in other studies reported in the literature. Continuous evaluation and updating of the program did not result in greater weight loss nor was it cost-effective. The participants who lost weight during the program tended to maintain weight loss over time. One-third of those participants attended additional weight-loss programs.
