You are five two 115 pounds and 15 years old you swim 3 and a half hours a day for your swim team practice how many calories should you consume to maintain your body weight?

Well you should calculate your BMR, which is how much your body burns ALONE without any exercise. Multiply that times 1.2 which is how much you burn A DAY. So eat the SAME amount you burn a day everyday and your weight stays the same! Good Luck!
