In addition to what others have written, stop using food as a reward. Part of Atkins is also developing good food habits. Using food as a reward is bad because it reinforces the ideas that "I've been good, so I can eat this chocolate cake." or "I've had a bad day....I HAVE to eat this entire pizza."
So stop using food as a reward----break all the bad food habits you've acquired during your lifetime and adopt new healthier ones.
