having a fat belly

How come I weight 103 and have such a fat belly that sticks out?

I am 4’7 or 4’8, I weight 103 and have a fat belly that sticks out somewhat a lot. I did some research and said that I was in a healthy stage? I am also 13.

Sounds to me that there is nothing wrong with your weight. If you think that your belly sticks out too much, perhaps what you need to do is a few sit ups to help tone up the muscle in your abs. When these muscles are not exercised they relax and seem to stick out. Do at least 20 sit ups two or three times a week. In a couple of weeks you should noticed a difference. This will help tone and flatten your belly area.
