Dude, you're 14 don't deprive yourself of food or exercise at this vital time in your life or you will regret it when you won't be as strong as you could have been when you become older, you won't be as tall as you could have been when you're older and you body might not become proportionally right.
I know looks is important to a kid your age but once you've fully grown thats when you can do all the dieting and stuff that you want.
The way you should look at is - eat as much as you want but make it healthy, for gods sake eat some meat - i'm guessing you might be a muslim? Forget that crap I did and eat meat on the side so your parents don't know lol. And exercise a lot take up loads of sports.
