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
“Live long and prosper.” -Spock
“Live long and drop dead.” -Grok
Got your attention? (Thought so.) Sisson’s gone morbid, you say. Not exactly. Death is on the docket for today but more so the time leading up to death – (for some) a period of morbidity during which we experience major illness and impairment. We live, of course, with the prospect of our own mortality and how it will befall us, but we’re also emotional witnesses to that of our loved ones. I’ve lost many family and friends at this point in my life. Although I believe most had a good life, not many had what any of us would consider a “good death.”Read More
Dr. Loren Cordain and a few MD colleagues have recently published a paper (PDF) called “Organic Fitness: Physical Activity Consistent with Our Hunter-Gatherer Heritage.” It makes for a great companion piece to Primal Blueprint Fitness, and it encapsulates quite nicely the breadth of research into the physical activities of our hunter-gatherer ancestors. Read the whole thing. There’s probably nothing really new to you guys already well-versed in this stuff, but it’s good having it all in one space, and it’s good having it from more sources (not just me). If someone ever asks you why you go barefoot, avoid weight machines, squat below parallel (don’t you know it’s bad for your knees!?!), go on hikes for fun without sunscreen, and hate treadmills, you can send along a nice, neat package including the PBF eBook and the Cordain paper. This isn’t a “nyah, nyah, proven right again!” type thing (well, kinda). This is a “buttressing the incoming unavoidable inexorable impossible-to-ignore flood of evidence in favor of listening to evolution in matters of health and fitness” type thing. The times they are a changin’, eh?
Anyway, let’s get to the meaty bits of the paper – to what they call the “fundamental elements of ‘organic exercise,’ which may serve as a template from which to design a fitness strategy for adults living in today’s modern industrialized culture.” I’ve bolded and italicized their words (from a section of which the title of this article is derived) and followed up with my commentary:Read More
When I introduced a forum thread asking folks to share their top three challenges in going Primal, one issue got major traction: the S.O. factor (significant other, for those of you not into the whole online brevity thing). It’s a familiar story. One partner takes on a new health commitment. Life changes for that person. He/she goes through struggles, triumphs, growth – an entire physical and psychological process that potentially leaves a relationship chasm in its wake. Then there are the logistics, a menacing obstacle course of loaded questions and irksome details. Do you still eat together? Who cooks (not to mention shops)? Do we have enough pots and pans to make two different meals each night? How do we handle the kids’ food? Finally, what does it mean for the arrangement when one person’s food expenditure overshadows the other’s?Read More
While I think the idea of adult Paleolithic hunter-gatherers regularly dying at age 30 can be laid to rest (sadly, I reckon that particular misconception has an impressive life expectancy), last week’s post on the Gurven-Kaplan paper brings up another question: if the human potential lifespan of 68-78 years, or roughly seven decades, is an evolved, inherent, even genetic trait, what is the evolutionary justification for its selection? Where is the advantage?
The classic Darwinian view is that selection of traits revolves almost entirely around fertility. Once an animal can no longer produce offspring, it has no “reason” to go on living. Since a genes’ survivability ultimately comes down to reproduction, whether an individual can have kids is the primary determinant of viability.Read More
Speculation on ancestral lifespan is fun and potentially illuminating, but I think examining living, albeit imperfect, examples of modern hunter-gatherers offers greater insight. Sure, the environment has changed, wild food sources have shrunk in diversity and availability, and modern civilization has encroached and meddled and disrupted, but the few remaining hunter-gatherer populations exhibiting relatively untouched traditional lifestyles represent the most promising window into what life actually looked like and how long it lasted for our ancestors. Luckily, a couple of researchers – Gurven and Kaplan – had the bright idea to look at ethnographic studies on actual, living HG populations and analyze the available data on actual lifespan and mortality therein. They found some interesting stuff.Read More
It has become an article of faith among, well, basically everyone, that our ancestors lived short, brutal lives. What are they touting as the average lifespan these days – 35 years old or so? I’ve heard anything between 25 and 40 years. The common counter is that infant mortality rates were higher than they are today, thus skewing the average. It’s also often pointed out that a relatively benign accident or illness by today’s standards – a broken arm, a rolled ankle, or a minor infection – could have prematurely ended Grok’s life. And that these cases say nothing about Grok’s potential to live 70+ years. The “short and brutal” meme has wedged itself in the public psyche, and it’s going to take a lot to extract it from its seemingly intractable position.
I’m going to riff a bit on something I’ve been thinking about regarding ancient human bones. This isn’t an official stance or anything; I’m just thinking out loud. Let me know what you think in the comment board.Read More
Dairy, as I’ve discussed, is a somewhat hazy matter in the Primal Blueprint. With adequate reasons from solid thinkers both for and against, I’ve relegated dairy to the provisional, the peripheral, the speculative even as I choose to modestly indulge in it. As with most Primal gray areas, some forms appear less controversial than others. Raw, fermented, full fat dairy offers much more health benefit with fewer reservations than processed, low fat renderings. (Isn’t that always the case?) From a Primal perspective, however, dairy still remains somewhat of an enigma. Hardly one of the original, universal foods in human evolution, milk entered the scene at a surprisingly late date – only some 9,000 years ago with the advent of animal domestication. Researchers have long traced the “progression” of Grok’s dairy intake from the Middle East into Europe, where milk actually became an unusually significant dietary staple. New research into the dairy “drift” now offers more details than ever surrounding this relatively isolated, albeit dramatic, evolutionary event.Read More
As you may already be aware, I’m not a huge fan of long, protracted warmups or pre-workout stretching. Workouts should be effortless, enjoyable, almost fleeting interludes between the activities you really want to spend your time doing, and spending twenty minutes beforehand to “lube up your joints” and “grease the gears” doesn’t appeal to my sensibilities. Additionally, if I’m going to burn time doing traditional, static, gym-class stretches they’d better confer some real benefits. You know, things like reduced injury, reduced soreness, improved performance. Yet studies are either mixed, show no difference or point to the exact opposite.Read More
When we think of Grok, we often imagine him in full-fledged hunting action – spear in hand, muscles in action, eyes on the latest prize prey. (Hence, the logo.) But such dramatic displays of power and prowess were fairly limited engagements. Grok, of course, had no full-time job. The lives of hunter-gatherers entailed much more than our label for them suggests. Experts who have studied modern hunter-gatherer societies estimate that most members of these communities spend about 3-5 hours a day “working,” which included all the basics of their food preparation. So, what else did Grok and his contemporaries do with their time? Could it be that hunter-gatherers weren’t poor slugs incessantly roaming and writhing in near starvation? Could it be that most of the time they actually had ample leisure time – to play, create, decorate, imagine and invent? Yes. Now ain’t that a kick in the head?Read More
Since you’ve gone Primal all sorts of strange questions pop into your head. And since you’ve gone Primal life has definitely changed. You wore Vibrams to your last shareholder meeting. The idea of skipping two, or heck, three consecutive meals, seems perfectly reasonable, and your idea of a frozen treat is that local, pastured lamb you’ve got sitting in your chest freezer, deconstructed. You’re even toying with the idea of ditching shampoo. Sheesh. To outsiders, you’re that weird caveman guy who eats steak for lunch and keeps a jar of coconut oil at his desk and thinks he’s living in the Paleolithic, but really, you’re just someone who’s discovered that keeping an ear, an eye, and a foot in our ancestral past makes living in the present that much more fulfilling – and healthy.
But how far do you go? What about sleeping? (Here come those questions…) Should we care how and upon what type of bedding Grok slumbered?Read More
