The treatment of adult obesity through direct manipulation of specific eating behaviors.

The present study investigated the effects of three different conditions on weight loss in adult obese subjects. The three conditions were: (1) Monitoring-Contract (MC) in which subjects were reinforced by the return of a valued possession for changes in eating habits; (2) Monitoring (M); and Attention-Placebo (AP). Subjects in the MC group lost significantly more absolute weight and a significantly greater percentage of weight at the end of treatment than did the subjects in the M and AP groups. These changes were still manifested at a 2 month and a 6 month follow-up. The long-term advantages of a weight reduction program which focuses on a gradual and systematic weight loss through changes in eating habits are discussed.
