Jump Start Your Metabolism
Some things that affect whether your metabolism is speedy or sluggish include things you don’t control, like your age, sex, and genes. Sometimes a sluggish thyroid could decrease your metabolism. But once you find out that it is normal, speeding it up is up to you. Focus on what really does make a difference: exercise. Muscle cells need a lot of energy, which means they burn a lot of calories. In fact, they burn more calories than fat cells, even when you’re not exercising. So the time you spend working out reaps benefits long after you stop sweating. Exercise becomes even more important as you get older. You naturally lose muscle mass with age, which slows down your metabolism. Working out can stop that slide.
