Physical Activity for Weight Management
Physical activity is beneficial for weight loss because it enhances the ability to achieve a negative energy balance by increasing energy expenditure. Physical activity also facilitates weight loss and maintenance through increased metabolic rate, increased lean body mass, and psychological factors. Habitual accumulated energy expenditure through physical activity allows long-term energy balance for achieving and maintaining weight loss. Physical activity promotes the production and favorable balance of anti-inflammatory myokines contributing to many of its metabolic benefits. The physical activity prescription should be customized with consideration for any underlying health factors. The prescription should include details about the type, frequency, duration, and intensity of the physical activity. Adults should accumulate ≥150 min of moderate-intensity or preferably ≥75 min of vigorous-intensity (or an equivalent combination) aerobic physical activity weekly. Moderate-intensity physical activity of ≥300 min per week or > 150 min of vigorous physical activity per week is preferred due to additional health benefits. Include resistance activities ≥2 times per week. When physical activity is limited due to health conditions, adults should be as physically active as their condition and abilities allow. Patients must learn to implement new activity habits to replace sedentary behaviors. Use behavioral modification strategies such as self-monitoring, making specific goals, increasing physical activity in daily living, developing skills to cope, and enlisting social support.
