Well, we need the growth and hormones happening in their allotted time and if we mess with it, get radical with the dieting or overeating, etc. it can mess us up forever. I hope you're not doing anything I wouldn't do :-) lil bit, if you're trying to lose weight and you don't need to, the combination of what your body is trying to do naturally and what you're forcing on it can cause a heck of a mess for the rest of your life. I'd kind of think about DePressMe's words. It's one thing to lose weight when you're older and your body is "stable" for a bit and a whole different thing screwing with it when it's screwing with you.
