Dietary carbohydrates (e.g., starches, sugars) provide the body's primary and preferred source of fuel for energy. They also maintain the body's backup store of quick energy as glycogen . Human energy is measured in heat units called kilocalories, which is abbreviated as kcalories or kcal . Each gram of carbohydrate consumed yields 4 kcal of body energy. In a well balanced diet, carbohydrates from all sources should provide approximately 45% to 65% of the total kilocalories.
Dietary fats from both animal and plant sources provide the body's secondary or storage form of energy. This form is more concentrated, yielding 9 kcal for each gram consumed. In a well balanced diet, fats should provide no more than 20% to 35% of the total kilocalories. Approximately two thirds of this amount should be from plant sources, which provide monounsaturated and polyunsaturated fats, and no more than 10% of kcals should come from saturated fat.
Ideally protein would not be used for energy by the body. Rather, it should be preserved for other critical functions, such as structure, enzyme and hormone production , fluid balance, and so on. However, in the event that necessary energy from carbohydrates and fat is insufficient, the body may draw from dietary or tissue protein to obtain required energy. When this occurs, protein yields 4 kcal per gram. In a well-balanced diet, protein should provide approximately 10% to 35% of the total kilocalories .
Thus, the recommended intake of each energy yielding nutrient, as a percent of total calories, is as follows :
Carbohydrate: 45% to 65%
Fat: 20% to 35%
Protein: 10% to 35%
