Twenty-four obese women were randomly assigned to 1 of 2 group treatments: behavioral choice treatment (BCT) or traditional behavioral treatment (TBT). BCT uses decision theory to promote moderate behavior change that can be comfortably, and therefore permanently, maintained. Groups completed a moderate-intensity walking program and obtained feedback from computerized eating dairies. The TBT group evidenced greater weight loss at posttreatment. However, the TBT group also evidenced a trend to regain weight, whereas the BCT group continued a slow weight loss during follow-up. Exercise followed a similar pattern. Both groups decreased in restraint and increased in self-esteem.
