well...it's ok to ask someone to help you out with diet changes, but you should see a nutritionist, or make one yourself, because we're strangers. We don't know what foods you are allergic to, what foods you actually like to eat, and the things that you are willing to eat (there are picky eaters here.), and when eating is convenient for you, and what your goals are.
So it seems like you just need to lose some of the belly fat. It's easy to get rid of it by being more physically active, but also start eating a healthy diet. As a teenager, it's hard to cut out all the saturated fats, and junk food. I'm still one, and I can't help but to go out with my friends for dinner, and drink beer, and party, but other than that I try my best to eat healthy and get regular exercise. What I do try to do, is eat those "bad foods" in moderation, so I don't completely kill my diet.
Make sure you eat enough fruits and veggies. Try to cut out simple carbs, and with your sandwiches for school, make sure the bread is 100% whole wheat. Meat isn't bad for you at all. Protien is good. But I would try to stay away from stuff like ground beef, and instead eat lean chicken, turkey and fish and other seafoods. As for sandwiches, try not to eat those processed deli meats. Those are bad. I also try to stay away from creamy dressings, mayo, and deep fried ANYTHING.
Also, make sure you're eating enough. Don't starve yourself, because your body will go into starvation mode, and you don't want that. So make your own diet. See whats good for you.
