The Primal Blueprint author Mark Sisson presents a fun, easy-to-follow, practical guidebook to help you “get Primal” in just a few weeks.* First, you’ll learn eight Key Concepts that represent the most important day-to-day elements of Primal living; then, you’ll tackle five Action Items that will literally reprogram your genes toward a long, healthy and energetic life. The Action Items are presented in a fun and life-transforming 21-Day Challenge, featuring daily diet, exercise and lifestyle endeavors with corresponding journal exercises. Join us, and leave behind the regimented, carb-dependent, fat-storing Standard American Diet (SAD) and the chronic, overly stressful exercise patterns recommended by conventional wisdom. Take the 21-Day Challenge and promote optimal gene expression by smoothly transitioning into the evolution-tested lifestyle behaviors of our hunter-gatherer ancestors*. When you eat Primally, you transform from a “sugar burner” into a “fat-burning beast.” Stored body fat becomes your preferred fuel choice, and energy, hormone, metabolic and immune functions are automatically optimized.* Included is an intuitive mix of Primal workouts that’ll help you get exceptionally fit in only a few hours per week—and have fun while you’re at it! The Primal Blueprint 21-Day Transformation is stocked with photos, diagrams, concise section summaries, workout descriptions and resource lists for Primal-approved foods and foods to avoid, recipe suggestions and detailed real-life success stories to help you stay confident and focused on your Primal journey.
