The Primal Blueprint is a simple, flexible plan to help you look and feel your best without struggling or suffering, by adapting the simple lifestyle practices of our hunter-gatherer ancestors into modern life. Sisson presents the compelling premise that you can reprogram your genes in the direction of weight loss, health, and longevity by following 10 immutable Primal Blueprint lifestyle laws validated by two million years of human evolution. Weight loss is largely about insulin; moderate your production by eliminating sugar and grains, and you will lose the excess body fat you desire even while eating delicious, satisfying foods. Plus you will improve your energy level, reduce inflammation, and eliminate disease risk. Eating meat, eggs, and a generally high-fat diet not only is healthy but is the key to effortless weight loss, a healthy immune system, and boundless energy.Slowing down your typical cardiovascular workouts, and incorporating brief, intense strength sessions and occasional all-out sprints can produce fitness benefits far superior to workouts that are longer and more grueling-and can eliminate the risk of burnout.
