The diet is definitely low carb, but I don't think that fully explains why it works so effectively. All the food I eat is whole, natural, fresh food. Nothing from a wrapper, package, box, jar, or can. All prepared fresh, and highly nutritious. I think my body starves for nutrients, and continues to ask food food until it gets what it wants. When I eat burgers and fries, I don't get nutrients, and therefore my body is asking for food again in 2 hours. What it is really asking for is nutrients, not calories.
I didn't figure this out on my own, but rather had it explained to me in bits and pieces over several different books. A fewof these books nailed it down pretty solidly. Here they are:
This books hits the nail on the head for me. The Primal Blueprint, by Mark Sisson.
The diet and workout style match what I'm doing almost exactly.
The Chipotle Diet also covers 8 of the 9 rules laid-out by Jack Challem in his book called "Syndrome X". I won't outline the whole book here. If you are at this website, You should read this book! I guarantee it will help you.
Buy the Book.
If you have already read the book, let me know what you think of it.
