Two weeks ago—after numerous testimonies by unrelated friends—I started eating in accordance with the primal blueprint diet. It's a very strange phenomenon to encounter someone promoting that you (1) cut out grains and (2) start eating more fat, but, in essence, that's why Mark Sisson's diet is about. I only plan on weighing myself every month on the diet, so I can't yet testify for any particular loss in pounds, but I will say that I feel much healthier already in terms of energy. I often post articles from the author's website, but you should all check out the book. It's a quick read and is very easy to follow.
