Although there is such a thing as a slow metabolism, it’s rare. And it’s usually not what’s behind being overweight or obese — that’s ultimately a result of interactions among genetics, diet, physical activity and other factors. Metabolism is the process by which your body converts what you eat and drink into energy.
Muscle cells require more energy to maintain than fat cells, so people with more muscle than fat tend to have a faster metabolism. As we get older, we tend to gain fat and lose muscle. This explains why your metabolism may slow down as you get older.
Your muscles first burn through stored glycogen for energy. “After about 30 to 60 minutes of aerobic exercise, your body starts burning mainly fat,” says Dr. Burguera. (If you’re exercising moderately, this takes about an hour.)

Glycogen Conversion Glycogen has to bind with water in order fuel your muscles. As exercise becomes more routine over time, your muscles will become more efficient and need less glycogen to maintain your energy. As that happens, your muscles will retain less water and you will see that added weight come off!
