Metabolism is the energy (calories) your body needs to function, and it operates at a different rate for each person. Metabolic rate is determined by uncontrollable factors such as gender (men tend to have higher rates than women), heredity, and age (metabolism tends to slow down after age 40 due in part to hormonal changes), as well as controllable factors such as weight, activity level, and what and when you eat.

Here are some tips from nutrition, exercise, and medical experts to help you boost your metabolism and ditch a few extra pounds for good.

Note: "People living with diabetes should check their blood glucose levels frequently to make sure that they do not become hypoglycemic with the decrease in calorie intake and the increase in physical activity," recommends dietitian Toby Smithson, R.D, a spokesperson for the American Dietetic Association.

"Also tell your health care provider about your intended lifestyle changes for possible adjustments of medications."
