Combining modern genetic science and evolutionary biology, The Primal Blueprint dispels a number of the myths that modern medicine and conventional wisdom have come to accept as fact. Author Mark Sisson takes the reader on a fascinating journey through human evolution, comparing the life and robust health of our hunter-gatherer ancestors with a day in the life of a modern family—exposing potential health issues that arise from trying to do the right things living in the 21st century. Sisson offers a solution in 10 empowering Blueprint Lifestyle Laws that can help us reprogram our genes away from disease and pain towards a direction of effortless weight loss, vibrant health and boundless energy. The reader learns how the right high-fat diet can actually help one lose weight; how popular low-fat, grain-based diets might trigger illness, disease, and lifelong weight gain; why doing too much cardio exercise might actually suppress the immune system and how some of today's most common medications might make a health condition even worse. The consummate book on Paleo or Primal diet.
