The role of physical activity in the control of obesity

An exercise programme is an important part of the management of the obese patient. Exercise may increase both the specific dynamic action of food and the post-exercise metabolic rate, in addition to its direct caloric cost. Moderate daily exercise aids regulation of the appetite and may reduce the voluntary caloric intake of otherwise sedentary persons. Post-prandial activity may utilize more calories; therefore an adequate breakfast and avoidance of late night eating may be effective in weight control. A better tolerated and more nutritious diet may be allowed, and lean body weight better preserved, by combining exercise with a dietary programme. Regular exercise may also reduce some of the more serious life-threatening complications of obesity and poor dietary habits, allowing greater freedom in the pursuit of other pleasures.
