Metabolism is the set of chemical reactions that occur in living organisms in order to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments.

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.

The number of calories your body uses for these basic functions is known as your basal metabolic rate.
