The truly negative aspect of what you did, was to eat too much. That is really what makes us fat. And that is what you must bring under control if you are going to lose weight and then maintain your goal weight. You could have eaten a lot less and still had an enjoyable day. 30% of the food volume you ate would have been reasonable. Certainly not much more.

Your episode should serve as a warning that you still need to work on self control. I think it is something we must all cope with on a daily basis; and learn to control our desire to overeat. Atkins makes it easier to do, but it still requires constant vigilance on your part.

Good Luck!
