Girls aged 11 to 13 need 1,800 to 2,200 calories per day while those between the ages of 14 and 18 need 1,800 to 2,400 calories per day, according to the Academy of Nutrition and Dietetics. One of the main factors affecting the calorie needs of teenagers is activity level.
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.
