Overall, the diet is high in protein, moderate in fat (mainly from unsaturated fats), low-moderate in carbohydrate (specifically restricting high glycemic index carbohydrates), high in fiber, and low in sodium and refined sugars.  The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds.
Diana Schwarzbein is another M.D. that has come to realize that low carb is what works. See reviews at The Schwarzbein Principle. The book is based on her work with insulin-resistant patients with Type II diabetes. She concludes that low-fat diets cause heart attacks, eating fat makes you lose body fat, and it's important to eat high-cholesterol foods every day.
During this program there is no calorie counting, no measuring, and no weighing yourself for the entire 30 days. I know that can be hard — especially if you’re feeling totally bloated (which can happen in the beginning) or particularly svelte in the later weeks. Just don’t do it. Even though a lot of people’s weight begins to normalize during the 30 days, the program focuses a lot on the “non-scale victories,” as in how you’re feeling. Is your sleep better? How’s your skin? Do you feel like doing cartwheels with that extra energy? Cool.
The Raw Paleo Diet & Lifestyle site is a resource created by members of the Raw Paleolithic Diet community for people looking to improve their health by choosing a more historically natural approach to diet, fitness and lifestyle. They have two forums: Raw Paleo Forum. It has some activity. And Raw Paleo Diet, or RVAF Raw Veg and Animal Foods Group, a forum for followers of semi-RPD diets, (such as Aajonus Vonderplanitz's Primal Diet/Weston-Price Diet/Sally Fallon/Instincto) and followers of the NeanderThin/Paleo/Stefansson Diets, who, for health reasons, wish to pursue a more fully Raw, Paleolithic variation of those diets.
Evolutionary biologist Marlene Zuk writes that the idea that our genetic makeup today matches that of our ancestors is misconceived, and that in debate Cordain was "taken aback" when told that 10,000 years was "plenty of time" for an evolutionary change in human digestive abilities to have taken place.:114 On this basis Zuk dismisses Cordain's claim that the paleo diet is "the one and only diet that fits our genetic makeup".
