You get your calories or energy from what you eat and drink. To maintain a healthy weight, you have to balance your daily calories with how you use them. If you need to lose some pounds, the best approach is a combination of healthy diet and physical activity. And studies show the only way to keep that weight off is to be active on a regular basis.
Different types of activities use up different amounts of energy. How much you weigh and how much muscle you have also makes a difference in how many calories you burn.
