I heard Mark on the Joe Rogan podcast and new pretty quickly that what Mark was saying made such simple and logical sense that I immediately ordered the book. Starting that day, I cut out carbs and sugar and dropped 6 lbs in 10 days! Remarkable! I’m only a fourth of the way into the book but it is a great read and Mark does an excellent job of explaining the science behind the Primal way of eating. I highly recommend this book to everyone but especially those who have struggled with the “yo-yo” weight loss and gain diets. It’s time for a change and this book is it!
