Girls need approximately 2200 calories, while boys need 2500-2900 calories. Protein. Protein is also necessary for physical growth, and should account for 15-20% of total calories. However, protein deficiency is quite rare in the United States, so protein consumption need not be overemphasized unless the teen is following a vegetarian or vegan diet. Fat. Many teens consume too much fat. Like adults, the diets of teenagers should contain no more than 30% of calories as total fat and 10% of calories as saturated fat. Teens should limit high-fat junk foods, and include foods containing essential fatty acids including walnuts, flaxseeds, pumpkin seeds, sunflower seeds, and cold water fish. Calcium. Nearly half of all skeletal growth occurs during adolescence.
