When you're trying to lose those extra pounds and keep the weight off, it's good policy to understand how your body uses the food you eat. Your metabolism is the way your body processes everything you eat and drink, converting all that sugar, protein and fat into energy. It's a never-ending, two-part process of anabolism and catabolism. Anabolism is when energy is created and stored, and catabolism is when energy is released. All of this is controlled by the endocrine system, the system in charge a lot of our body's processes, from cell and tissue growth and repair to reproductive function and mood regulation.
While you can't directly control how your metabolism works, you can control what you eat, how much you eat and how much physical activity you get every day. These three factors have a lot of power over your metabolism. It always comes back to diet and exercise, doesn't it?
