“Among the researchers, gurus, doctors and coaches who offer alternatives to the establishment’s threadbare health gospel, Mark Sisson stands out. His Primal Blueprint is the distilled essence of decades of research and experience — a definite and clear, yet always achievable, approach to living that delivers satisfaction and results."

-Tim Rangitsch, Rapid City

"This is not an exaggeration, I had only tried the diet for less than 24 hours.. By the time I was making dinner I was feeling a lot better.. The stress headaches were a barely audible hum in the background.. After a nice healthy dinner with no grains or starches, good protein and a nice helping of mono fat as the main part, the pressure in my head was gone..and funnier still, I just wasn’t hungry for ages.."

-Martin F, Glasgow, Scotland

"Within the next 3 months, not only did my weight get down to 170 lbs, and my waist shrink to 31.5”, but my life had changed forever. Remember the litany list of medications I mentioned before? Depression medication: Gone. Blood pressure medication: Gone. Testosterone: Gone. And for the first time in 30 years…let me say that again…for the FIRST time in 30 YEARS. Asthma medications: Gone. Done. Finished. Wow! What a concept. Proper nutrition and exercise – the best medicine available to mankind."

"Mark’s Primal Blueprint is not only easy, and works, but makes such common sense. Yes, we all have the genes we were born with, but for the most part, it’s our lifestyle that determines how they express themselves and that my friends, in a nutshell, is what it all boils down to."

-Calvin

-Gabe, San Francisco, CA

"I have more energy than I have had in YEARS. I can finally keep up with all of my 5 kids, including our 16-month-old twins, all day and even have some energy leftover once they’ve gone to bed. I love being able to actually run around and play with my kids!"

But in a matter of several days, my energy sky rocketed, ! my digestive issues cleared up, and I performed better in the gym. Perhaps the best thing of all, however, is that I don’t ever really feel hungry, even though I eat much less (calorically and volumetrically) than I used to."

All this while enjoying the lowest body fat Ive ever had and most strength & muscle."
