The behavioral management of obesity is an approach designed to provide individuals with a set of skills that promote a healthier weight. A number of strategies are used to assist individuals in making gradual changes that can realistically be incorporated into their lives. Evidence is promising for behavioral programs, as results demonstrate an 8% to 10% reduction in initial weight during the first 6 months to 1 year of treatment. However, the long-term impact of these treatments remains unclear, as many individuals regain weight lost over time. The Diabetes Prevention Program and the Look AHEAD (Action for Health in Diabetes) trial are providing strong data on the long-term results of intensive behavioral management interventions.
