How many calories should a teenage girl burn every day to stay healthy (not lose weight)?

Don't Worry: Each individual has unique calorie needs based on their basal metabolic rate and level of physical activity. However, calorie counting really should not be undertaken by teenagers. Teens are growing and need good nutrition. Just focus on eating balanced, healthy meals and get plenty of exercise and sleep.

Your always burning: We all burn calories while sitting still, that is our basal metabolic rate or bmr. When we eat it increases our BMR in order to digest food we burn calories. When we exercise we burn calories. A balanced diet with six small meals per day, don't skip meals, and daily activity is a good way to start.
