The key to weight control is keeping energy intake (food) and energy output (physical activity) in balance. When you consume only as many calories as your body needs, your weight will usually remain constant. If you take in more calories than you body needs, you will put on excess fat. If you expend more energy than you take in you will burn excess fat.
EXERCISE plays an important role in weight control by increasing energy output, calling on stored calories for extra fuel. Increases metabolism during a workout and your metabolism to stay increased for a period of time after exercising, allowing you to burn more calories.
Lack of physical activity causes muscles to get soft and if food intake is not decreased, added body weight is almost always fat. Once-active people, who continue to eat as they always have after settling into inactive lifestyles, tend to suffer from "creeping obesity".
