What to Eat. Most teens need five to ten servings of grains or starchy foods per day, two to three servings of fruit, three to five servings of meat or other protein-rich foods, two to three servings of vegetables, four to five servings of dairy and two to four servings of fat each day.
Teens need somewhat more calories than when they were a bit younger. Teenage boys on average need 1,800 to 2,600 calories a day if they're 11 to 13 years, and 2,200 to 3,200 calories a day if they're 14 to 18 years of age. Teenage girls need more, too: 1,800 to 2,200 calories a day if they're ages 11 to 13, and 1,800 to 2,400 calories a day if they're age 14 to 18. Gender, body size, growth rate and activity level specifically determine how many calories teens need.
