Food Energy
The energy needs of athletes exceed those of the average person. It’s not uncommon for male and female athletes, especially those still growing, to have caloric needs exceeding 2,400-3,000 kcal and 2,200-2,700 kcal per day, respectively. The amount of energy found within a given food is dependent on the macronutrient (carbohydrate, protein and fat) content of the item.
