Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...Tell Me More
The Primal Blueprint is more than just a health and nutrition blog. You can find thousands of health and nutrition tips online, many of them quite sound. You can read well-researched and cited articles telling you what to eat, what not to eat, how to exercise, how not to exercise—and following their advice will give you good results. The Primal Blueprint does not enjoy a monopoly on results.
A big reason why the Primal Blueprint resonates with so many people is that it’s not only couched in hard science and useful information. It tells a story to which all of us can relate on a deep and meaningful level.
Back when I started this blog, I didn’t think the idea of Grok would take off. He was just a method for me to “storify” the dietary and lifestyle habits of our ancient ancestors. It made writing easier and more enjoyable. I even worried that people would find it trite, that it might detract from my message.
In time, it became apparent that people really dug the Grok narrative.
I understand why now. I’ve always been a big fan of fiction. I read non-fiction too, of course, but many people are surprised when they hear I probably prefer a good novel to the latest treatise on the genome. Novels don’t relay facts. They reveal deeper truths about the human experience. They distill the desires we share, the trials we face, the existential questions we ask. They engage us emotionally. That’s the power of story, and that is what the PB offers in addition to the actionable, well-researched information about health, fitness, and nutrition: the human story.
How do I connect to the Grok narrative? Apart from providing a unique approach to writing about health and fitness, what does it mean and how does it impact my life and my decisions?
If Grok were whisked away in a DeLorean DMC-12 going 88 MPH and dropped off in a present-day CrossFit box or big box gym, he’d marvel at the sheer stupidity of modern exercise.
To you, it’s normal. You’re steeped in it. But try to look at exercise from an ancient perspective. How would a paleolithic hunter-gatherer react to the things we do in the gym?
“Why are those people squatting down and standing back up over and over again? Why are they getting parallel with the ground, supporting their weight on the hands and feet, then lowering themselves until their faces touch the floor and raising back up? Why are they walking on a moving floor? Hey, why’s the floor moving?”
I mean, just writing those descriptions was incredibly difficult. Exercise moves are ridiculous when you stop and think about them. They’re unnatural.
Now, imagine you take the DeLorean back 50,000 years. The things people then were doing would look pretty natural. They might even look like a lot of fun.
In short, physical work was integrated into Grok’s life. He lifted an antelope carcass because he needed to feed his people, not a barbell because someone on the Internet told him he needed to train his posterior chain. He ran really fast to escape a predator or to race his buddy, not because he wanted to deplete glycogen stores and increase insulin sensitivity. He walked everywhere because that’s how people got around, not because he needed to hit 10,000 steps. He did these things because there wasn’t any other way to live. He didn’t have any other options.
Judging from the health of the few remaining people who “exercise” anything like Grok—extant hunter-gatherers like the Hadza—this type of physical activity is very effective. Despite never touching a barbell, treadmill, or pullup bar, the Hadza are extremely lean, fit, and have excellent metabolic health. Furthermore, modern research shows how beneficial taking a break from training can be, even for your physical fitness.
Whenever I start to stress over skipping a workout, I think about how Grok didn’t really exercise. How he and his people worked hard when they had to but took it easy when they could.
And I feel a lot better.
That’s sort of “reverse motivation.” It motivates me not to get out there and bust my ass in the gym, but to be okay with taking a break—which is more important than people realize.
People like to use the fact that paleolithic humans lived and ate in dozens of different environments featuring totally different climates, ecosystems, environmental inputs, and sources of edible plants and animals as an argument against the “paleo diet.” Arctic tundra Grok ate and lived very differently from tropical Grok, who ate and lived completely differently than Mediterranean Grok. This was the crux of the paleofantasy criticism: there wasn’t just one paleo diet, so Cheetos and McNuggets are totally fine.
I see it differently. Humans are the ultimate adaptive animal. We can make almost any environment work. Heck, we can thrive in a place as stark and severe as the Arctic and make it home. Thanks to our big brains and our capacity to respond to and overcome the slings and arrows of life, protracted exposure to difficult environments actually selects for a better, stronger, fitter genome. Our time spent in diverse ancestral environments made us who we are today.
That makes me even more gung-ho about heeding the lessons of our evolutionary history. This reality of our past—the multiGrokverse—actually motivates me.
I’m a big fan of freedom, liberty, and choice. All that’s great. But modern life presents us with too many choices.
When I’m in decision-making limbo, paralyzed by the overabundance of options, a quick “What would Grok do?” shifts my frame of mind. It doesn’t provide an answer in the moment, but it does break the mental loop of indecision to drill down deep into the essence of the choice. What are my true motivations? What do I hope to get out of this decision? What’s at stake?
Of course, your average paleolithic human wouldn’t be able to make heads or tails of the ridiculous things we lose sleep over, like picking a new big screen TV or plotting the next step along our career path. But as a mental exercise, asking the question is helpful. Grok didn’t concern himself with the superfluous because, for the most part, it wasn’t an option. His focus was food, shelter, friends, family, love, beauty, the weather, water, wild animals and enemies. We have a tougher job of discerning the essentials, but they haven’t changed much. And if you’re honest with yourself, most of your concerns come down to those basics.
Human history is a living document. 20000 years ago, the sea level was over 300 feet lower than it is today—given that humans tend to cluster around the coasts, who knows what the sea swallowed up? Our knowledge is only as good as the last discovery, and genetic anthropologists and archaeologists are making new discoveries constantly. So much of what I’ve written about the ancestral environment could change as new information surfaces.
That’s okay, though. Remember what I said about story? Its power lies not in the objective accuracy of the details but in the emotions and lessons conveyed. If a story gets the details wrong but conveys a truth about human nature, relays a moral lesson, or helps the reader become a better person, it has value.
Every day, I try to relay useful information. Whether I tell a story, make a new product, analyze a study, answer a reader question, or dig deep into a controversial subject, I’m trying to be useful to you guys.
I hope I’m succeeding.
That’s it for me, guys. What about you? How does the Grok narrative resonate most with you and your life? How do you use it to improve your health, fitness, and happiness?
Thanks for reading. Take care.
