What is your metabolism?
Your metabolism refers to the chemical processes that occur in your body that keep you alive — like breathing and breaking down food into energy. For these processes to happen, energy is required. Your body size, age, gender, and genes affect your metabolism.
If your energy requirements are low, your metabolism might be referred to as “slow”. For some people, a “slower” metabolism might happen if your muscle mass is low — because your muscle cells require more energy than fat cells. Or sometimes it might be due to a hormonal issue.
