Primal Blueprint author Mark Sisson presents a fun, easy-to-follow, practical guidebook to help you "get Primal" in only 21 days. First, you'll learn eight Key Concepts that represent the most important day-to-day elements living Primally, then tackle five Action Items that will enable you to 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.

You'll transition out of the regimented, carb-dependent, fat-storing Standard American Diet (SAD), the chronic, overly-stressful exercise patterns recommended by Conventional Wisdom, and other health-compromising elements of hectic modern life. Instead, you'll smoothly implement the evolution-tested lifestyle behaviors of our hunter-gatherer ancestors to promote optimal gene expression. By eating Primally, you'll transform from a "sugar-burner" into a Sisson's so-called "fat burning beast", where stored body fat becomes your preferred fuel choice, and energy, hormone, metabolic, and immune function are optimized automatically. With an intuitive mix of Primal workouts, you'll 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 photos, 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.

Unlike many complex, regimented, quick-fix programs, the Primal Blueprint 21-Day Transformation is a simple, sensibly-paced journey shaped by personal preference and a strong emphasis on enjoying comfortable modern life. The material is scalable for everyone, from Type-A fitness die-hards who might benefit from a more relaxed approach, to couch potatoes who need motivation to take that first step.

Mark Sisson guides you in a light-hearted, irreverent tone that will make you feel comfortable and inspired, and never intimidated. You can expect quick results in the first 21 days (fat loss, improved energy levels, fitness, and blood test markers), but your 21-Day Transformation is only the beginning of a life of ease and contentment that is possible when you live in harmony with your genetic requirements for health and long
