Document Summary
When energy input is greater than energy output, the person is in positive energy balance. Negative energy balance occurs when energy input is less than energy output. In order to lose weight, it is necessary to be in negative energy balance. The bene ts of physical activity include boosting self esteem, helping a person stay physically. T, helping with weight loss, and helping maintain lower body weight. Physical activity increases energy expenditure beyond basal metabolism by 15-35% The set point theory often refers to the close regulation of body weight. Treatment for overweight and obesity should be long term and a lifestyle change. Foods that are high in ber and water promote satiety. Lean body mass is the most important factor that increases basal metabolism. The bene ts of physical activity on body composition and metabolic rate include increased lean muscle, increased metabolic rate, decreased fat mass, and increased bone density.
