John, you ask people for advice, on how to exersize and eat less, then go around contradicting yourself, saying you're obsessed with food. Coming to this site won't help you lose weight if u keep that attitude. No one here, can stop you from eating except for you! I know it must be hard, but you have no right to complain about someone poking fun at you, if your not gonna do anything about it. Prove your little brother wrong. Show him that u can do anything if you want to badly enough. And if you simply can't try or put effort into it, than u obviously don't want it as much as u say u do.
