AbstractPhysical activity seems to be an important component of lifestyle interventions for weight loss and maintenance. Although the effects of physical activity on weight loss may seem to be modest, there seems to be a dose-response relationship between physical activity and weight loss. Physical activity also seems to be a critically important behavior to promote long-term weight loss and the prevention of weight regain. The benefits of physical activity on weight loss are also observed in patients with severe obesity (BMI ≥ 35 kg/m²) and in patients who have undergone bariatric surgery. Moreover, independent of the effect of physical activity on body weight, engagement in physical activity that results in improved cardiorespiratory fitness can contribute to reductions in health risk in overweight and obese adults. Thus, progression of overweight and obese patients to an adequate dose of physical activity needs to be incorporated into clinical interventions for weight control.
