Calculate the correct amount of protein. According to Drugs.com, 12- to 14-year-olds should consume approximately 1 gram of protein per kilogram of body weight each day. Girls aged 15 to 18 need slightly less protein, or 0.9 grams per kilogram of body weight. Find out how many kg your teenager weighs by dividing her weight in pounds by 2.2. For example, if your 13-year-old weighs 100 pounds, she weighs 45.5 kilograms, and should consume about 45 grams of protein each day.
The Institute of Medicine recommends that teenage boys consume at least 130 grams of carbohydrates each day and that 45 to 65 percent of their total calories come from carbs. So, teen boys should get 225 to 325 grams of carbs as part of a 2,000-calorie diet, 293 to 423 grams for a 2,600-calorie diet and 360 to 520 grams of carbs per day if they are eating a 3,200-calorie diet.
