That fatlogic... they're basically saying if these kids don't lose the weight by 18 it will then be impossible for them to lose it as adults. What a load of crap. I went off to Uni fat but I became human sized over the course of a few months. I've kept that weight off for over 5yrs now. I'm not special, I just don't eat junk and sit around like I did as a kid. Anybody who wants it bad enough can do it. Telling them it can't happen after 18 is a self fulfilling prophecy. Guess what will happen if these kids don't do it by 18 now? They'll just stop trying because everyone said it cant be done.
