I already have the most recent version of the Precision Nutrition system but recently purchased the book The Metabolism Advantage, also by Dr. John Berardi, published in 2006 (sometimes I do things a little backwards).
Here's the most impressive part to me though. The eight week plan is all mapped out, including meal plans, grocery shopping lists, the exercise plan and a workout journal. You literally could take it to the grocery with you or to the gym in your bag. The book wraps up with encouraging instructions on maintaining the advantage long term.
If you don't have The Metabolism Advantage already I would pick it up and work through it. It's a great addition to your toolbox for reaching your goals. I'm giving it an official Get Fit With Kelley stamp of approval.
