Well dear, I am not a health professional, but I do know that teenagers eat a fuck-ton of food (as growing young humans often do). I was a very active 16 year old and also recall feeling like I couldn’t eat enough, even during times of inactivity between swim and softball seasons. I think it’s most likely you’ve just got a large, teenage appetite - but you know better than anyone else when something is wrong with your body. If something is up and you honestly feel out of control, or your eating habits are becoming detrimental to yourself or those around you, please do seek help.
