According to the Dietary Guidelines for Americans 2010, sedentary teen girls ages 13 to 18 need about 1,600 to 1,800 calories a day, while sedentary teen boys within the same age range require about 2,000 to 2,400 calories daily to maintain healthy body weights.
(That means something between sitting around a lot and walking more than 3 miles per day.) If so, you probably can eat around 2,000 calories each day.

Sometimes, girls think they need to be thinner, even if they are not overweight.
