The best way to jump-start your metabolism is to exercise. Exercise will reduce body fat and increase lean muscle mass. By increasing lean muscle mass, metabolism will increase and aid in the weight-loss process. Muscle tissue uses more calories than fat tissue because it has a higher metabolic rate. Aerobic exercise, like walking, swimming or cycling, has the added bonus of speeding up your metabolism for 4 to 8 hours after you stop exercising. Additional calories will be burned off long after you stop exercising. Weight lifting, resistance or strength training, does not speed up your metabolism, but it does burn fat and increase your lean muscle mass which increases your resting metabolic rate.
