How many calories should a 15 year old girl get a day?

Answer 1

She should get about 1,500 calories if she is not very active and if she is active she could probably stand to take in 3,000-3,500 calories (for athletes like gymnasts,running track--wouldn't suggest this many calories for a cheerleader you probably would be looking for somewhere around 2,000 calories in that instance)
The amount of calories a 15 yer old should burn a day will depend on her height and weight. A girl of 15 needs to walk 3-4 miles per day to burn calories.
