How weird, I bought this a couple of weeks ago too! I definitely think it's worth every penny. The only reason I can say it might not be worth it is if you are a naturally thin person and don't have to watch what you eat.
I tailored an eating plan from his book (low-moderate carbs, zig-zag calories, 5 meals a day) and I am already seeing results - the weight is coming off even though I have crazy PMS this week!
momto2bratz, it is an e-book. I saved the files in acrobat reader and printed it out (at work) and put it all in a 2 inch, 3-ring binder.
Edited to answer Pam's last post: There is a lot of math in this book! I sat at my desk with a calculator to plan out how many calories I would need for each meal, and then broke it down into how many grams of carbs, protein and fat. I still think it was worth it - he gave a bunch of examples that made it much easier. I hate math and I actually had fun doing it...
