Short answer: If you feel good on it, why quit?
The Phase One Diet covers everything – proteins, carbohydrates, fats, fiber, phytonutrients, vitamins, minerals… Why would you need anything else?
Generally, I eat Phase One and “cheat” to Phase Two, (adding beans, tortillas, rice, etc.), from time to time.
But the heart of that question isn’t whether to advance to Phase Two. The heart of the question is usually, “When can I start drinking soda and eating pizza again?” Right?
Aren’t those the kinds of things that got you into trouble in the first place? You don’t want to return to the symptoms. So why would you return to the foods that helped create the symptoms?
Here’s how I think about it: I love the way I feel on Phase One. I never want to feel awful again. Occasionally, I’ll indulge a craving during a holiday or special event. But MOST of the time, I’m Phase One – happily so! Unless pizza is right under my nose, I never think about it. I don’t feel deprived at all on Phase One, especially with the recipes Denni and Kristin make on the show.
If you’re addicted to foods that give you problems, you actually think you’ll feel worse without them. That’s what addiction is: something that makes you feel good for a moment, but depletes you over time. You think that Phase one is hard, and the moment you’re able, you’re going to go rushing back to the snack cakes and buffet lines in order to feel better again. That is your addiction talking to you. Rob it of its power, and indulge in the delights of Phase 1. Plan for it to be your lifestyle diet, not a two-week experiment.
