Nope, I just bought the cookbook (Gourmet Nutrition) on Amazon. I did buy the supplements he recommended, and a Magic Bullet to make smoothies in the mornings, but those were not required. His free website (precisionnutrition.com) has lots of good articles and information. Try searching there to get beyond your plateau!
Try myfitnessplan.com for counting calories. It's very intuitive and easy to use. I liked its interface much better than WW or sparkpeople.
