Physical activity or cardiorespiratory fitness imparts a protective effect for chronic diseases of lifestyle, which is probably independent of fatness. <br>Physical fitness attenuates blood pressure, serum lipids, insulin resistance and other morbidity associated with the metabolic syndrome at any given BMI. <br>Physical activity contributes to weight management and the prevention and control of obesity directly through increased energy expenditure, increased fat-free mass, and increased fat oxidation. Indirectly, physical activity enhances compliance and self-efficacy to dietary and lifestyle change. <br>Current public health recommendations suggest that at least 30 minutes of moderate-intensity exercise daily may protect against most chronic diseases of lifestyle; however, this may be insufficient to prevent 'unhealthful' weight gain in many adults.
