Forget South Beach, Atkins and Ornish. The rules are all too complicated and hard to remember. That's why I invented my own personal regimen that doesn't require keeping a list, buying a book or learning a new recipe: I never have seconds. The diet made a big difference for me because I was in the habit of going back for more, whether I was hungry or not. Now I've reversed the formula: I stop eating whether I feel hungry or not. I've discovered I actually need a lot less food than I thought I did, redefined what it means to be full, and lost about a pound every two weeks. I also discovered an added benefit: everything tastes better!
