Some of the foods provide slow-releasing energy from healthy carbohydrates which are the bodys main energy source. We need a minimum amount of calories from food to sustain basic metabolic functions and more to carry out physical activities. One way to understand metabolism is to track a typical nutrient on its journey through the body. This approach can reduce your perception of fatigue because your brain which has very few energy reserves of its own needs a steady supply of nutrients.
