For normal healthy people, weight is gained by taking in more calories than the body needs. Therefore, if you want to lose weight, you either have to eat fewer calories or find ways to use up more calories you take in. Dieting is probably the most popular way of losing weight, because when on a diet, you are taking fewer calories.

　　However, the body needs many elements in order to stay healthy, and fad or starvation diets are bad because they are not nutritiously balanced. A better way of dieting is to keep track of everything you eat, either by your own careful choices or by buying, for a week at a time, the packaged meals sold by some diet companies. If you do not normally exercise, you should also begin sensible exercises for your age and lifestyle to help your body use up surplus calories.

　　In short, a combined effort of reducing the calories you eat and using up more calories than usual through exercises should help you shed off part of your body.
