what is aa metabolism
Probably not. There is such a thing as a slow metabolism. But slow metabolism is rare, and it's usually not what's behind being overweight or obese â 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. Even when you're at rest, your body needs energy for functions such as breathing, circulating blood and repairing cells. The number of calories your body uses for these basic functions is known as your basal metabolic rate.
