Abstract:
Examines the psychology and physiology of obesity, its assessment and treatment, the role of exercise in weight reduction, and new directions for the field. The health risks of obesity are discussed, particularly the controversy about weight reduction for persons less than 30% overweight. Several physiological factors are presented, including the set point theory of body weight regulation, the role of fat cell size and number, and dietary influences on body weight. Assessment issues are noted along with results from treatment programs for obese children and adults. The role of exercise is emphasized, not only because of increased energy expenditure, but also because exercise may suppress appetite, offset the decline in basal metabolic rate caused by dieting, minimize loss of lean body mass, and counteract the ill effects of obesity. Two problems in the field are raised: the misinterpretation of the strengths of behavior therapy and the trap of focusing on long-term results. New directions are urged, including aggressive approaches to dieting, treatment combinations, and the use of social support.
