Why do I love food so much?

Okay so i'm a 14 year old girl, and I LOVE FOOD haha. I eat SO much. But the thing is, i'm not fat. I'm actually in really good shape. I'm 5'9 and like 145 and play basketball. I eat so much food in one day. Like today, I had 3 pancakes, and 2 eggs, with a gl of apple juice for breakfast. Then at school, I always buy more snacks like candy. So then I had 3 snickers bars and a pack of skittles. Then at lunch, I ate 3 pizzas, 4 brownies, and 2 cans of soda. When I came home, I ate like 7 KFC potato wedges with another gl of apple juice. Then for dinner, I had a bowl of fried rice and beef and broccoli with and arizona iced tea. (that was probably the only healthy thing I ate all day haha) and right now as i'm typing, i'm eating ruffles chips, haiwan bread, and more potato wedges, and a cheese stick all with apple juice. (I LOVE APPLE JUICE hahaha) So yeah. I eat like this almost every single day and never feel sick. My mom says for me to stop eating that much, but I don't see the problem in it as long as I don't get fat and gain weight. My body is actually really toned, haha I have no clue how, but it is. I play PF in basketball and have strong legs and arms. And a lean stomach. So yeah, I sort of wanna stop though to make my mom happy. So how can I overcome my obsession of food? Thanks!
