Dear Sir/Madam，

I'm  middle school student of sixteen. I have a weight problem. Some boys often made fun of me and are unfriendly with me. They call me “Meat ball”，it makes me feel unhappily。 I'm now worried about my weight. Although I am a bit fat, I feel quite well. I enjoy my meals. I love eating meat very much. ButI like sweet foods， too. Now I am getting fatter and fatter. In the past two months, I have put on 5 kilos. I've got worrying about this, but I don't know how to lose weight quickly. Who can tell me the right way of lose weight? If you give me some advice, I'll be grateful.
