Whats the best way for a teenager to lose weight?

Im 16 and i want to lose about 10 to 15 pounds.In 2 to 5 weeks.I weigh about 150 to165.I don't know exactly.My height is 5'6 , 5'7.Most of my fat is around my stomach and thighs.I have been considering starving my self or making my self throw up.I know its not the best thing to do but i am desperate.So please just help me find diets that are faster but i hate calorie diets so please don't suggest that.I just want a fast healthy diet thats easy.So please i would really like your suggestions.Thanks:)
