Carbohydrates are your body's preferred source of energy. In fact, your body turns all the carbs you eat into glucose, which provides a quick energy supply. Your body can also store carbs in your liver and muscles as glycogen, which it can use later for energy when you need it. The carbohydrates you donât need right away and that canât be stored in the liver, though, turn to fat.
The body can burn carbs and protein for the same yield of 4 calories per gram. Nutrients are chemicals that your body requires for growth, development, metabolism and proper function. Carbohydrates, fats and proteins belong to the macronutrient category because your body needs them in large quantities. Carbohydrates directly supply glucose, your body's preferred fuel source. While proteins have other primary roles, they can also supply energy whenever carbohydrates are not available.
