I was 250, got down to 210 in a zealous fit of diet and excercise a couple of years ago. I seem to have settled at around 230 now (still obese, I'm not sure that label is helping me). I have gone back to not eating well but I did at least find a sport and stuck to it, so some good did come out of it and I feel a lot better than I did.
What I want OSU to do is to come up with something that means I can continue to eat badly but not suffer the bad effects, it's not that I don't know how to eat well or that I don't enjoy health food, it's just that I enjoy the unhealthy food as well. I found it far easier to change my excercise habits for the long term than to change my diet habits
