I've been here nearly 4 years and I'll tell you what matters most:
DON'T QUIT. Stay with this. Nearly everyone quits and goes back to old habits. Don't be one of them. Do this for yourself. You can release FIVE POUNDS, 20 times. 2# per week is over a 100# in a year.
The reason people don't get to goal is THEY QUIT. Stay away from "just one cookie" or the "Oh, they will be upset if I don't eat with them." Do this for you.
