How can I lose weight fast?!?

I'm 12 and I really need to lose weight, I feel so fat, I know I'm not like obese or overweight or something but everyone else is skinnier than me and I just wanna fit in. I want to lose about 10-15 pounds in a month or so. I'm 5'5" and I'm about 110 pounds. I'm sort of lazy so is there anyway to do it without exercising for hours, I"m willing to exercise but not for that long. And what kind of food can replace my junk food? Stuff that's delicious and nutritious! Thanks, I just want something quick, easy, but doesn't make me suffer. Oh and I don't need people saying that I'm too young or I don't need to lose weight, I want to and if that's my decision than respect it.
