Think of your body as a sophisticated machine, constantly working, moving, and repairing itself. For all these functions, it requires fuel, and that fuel comes directly from the food you eat.
What is Metabolism? Your Body’s Energy Engine
Metabolism is the complex set of chemical processes that occur in your body to maintain life. It’s how your body converts food and drinks into energy. This energy is then used for everything from breathing and circulating blood to thinking and moving. Even when you’re resting, your body is burning calories to keep vital functions running—this is known as your Basal Metabolic Rate (BMR).
- Anabolism: Building up complex molecules from simpler ones (e.g., muscle growth).
- Catabolism: Breaking down complex molecules into simpler ones (e.g., breaking down food for energy).
The Role of Calories: Your Energy Currency
A calorie is simply a unit of energy. When we talk about calories in food, we’re referring to the amount of energy that food provides to your body. To lose fat, you need to consume fewer calories than your body expends, creating a
