Energy requirements of the body — Science Learning Hub

The macronutrients (carbohydrates, proteins, fats and oils) we consume in our diet help to supply the energy needed by the body to keep it working. This energy is used to drive the complex chemical, mechanical and electrical systems of the body. The rate of energy release from macronutrients by chemical processes occurring in the body is known as metabolic rate.

The Body’s Fuel Sources – Human Kinetics

Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the body’s principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen. During exercise, muscle glycogen is converted back into glucose, which only the muscle fibers can use as fuel.
