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.
