Meet Mark

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...

Restless Legs Syndrome: Causes, Factors and Treatments

For anyone who’s experienced it, the frustration can be miserable. The countless tossing and turning, the minutes that tick by (turning into hours), and you STILL haven’t gotten a modicum of decent sleep. No matter how hard you try to ignore it, that urge to constantly move or stretch your legs just won’t let up.

Restless legs syndrome (RLS), aka Willis-Ekbom disease, affects a decent chunk of the population: thought estimates vary wildly, this 2017 representative survey places its prevalence between 5.7 and 12.3% of the population. That’s up to around 40 million people in the U.S. alone who go to bed every night knowing they’ll likely be kept awake for hours with that unrelenting, restless sensation.

Dear Mark: “High-Fat Diet,” Potential Type 1 Diabetes, Keto Cure?

For today’s edition of Dear Mark, I’m answering three questions from readers. First up, what are we to make of a recent study claiming to show that “high-fat diets” are harmful to rodents? Is it truly a high-fat diet, and what does it mean for us? For the second question, I field a comment from a reader experiencing a confluence of troubling symptoms and test results on his keto diet. And third, does keto actually cure diabetes, or just manage it?

Rest and Recovery: A Whole New Perspective (and A Giveaway)

If you’re a type-A, hard-driving peak performer, my hope is that this post will stop you in your tracks.

Today I want you to completely rethink your basic philosophy about how you manage both your fitness activities and the assorted stresses of hectic, modern life. This post was inspired by a great article from training expert Joel Jamieson of 8weeksout.com titled, “All Pain, No Gain: Why The High Intensity Training Obsession Has Failed Us All.” Joel’s message set off a firestorm of internal dialog among members of the Primal Blueprint team. (Catch Brad Kearns’ recent interview with him for the Primal Blueprint Podcast.) After much back and forth and additional research, I’m eager to get you reflecting and commenting on the genuine nature of recovery from an entirely new angle.

What Collagen Does For Performance

I’ve always been a student of performance—in my athletic days and now. Whether it’s nutritional intake, training strategies, or supplement choices, this is where science comes to life for me. Over the years, I made this interest work for my fitness performance and now for my optimal health. It’s not about “hacking” the body’s functioning but understanding it from the ground floor up. This knowledge helps me live and age through life more on my own terms, which is exactly the way I like it.

How to Find Mental Strength When Dealing With Illness and Injury

However tough, rugged, and badass we might consider ourselves, the fact is none of us is indestructible.

The human body, for the miracle that it is, is vulnerable as well as mortal. Even those of us in perfect health may at some point become injured—with or without the possibility of full recovery. Most of us are down for the count (or moving more slowly) a couple times a year with this or that virus. But even with the best Primal efforts, there are those among us who will go through medical crises. For all of us, age will inevitably diminish some of our faculties (although not how the culture tells us it must).

How we mentally move through these experiences will certainly have a hand in our prognoses, but more importantly it has the power to cultivate a more unconditional resilience.

“What’s That?” Ear Health: Dietary and Lifestyle Choices that Preserve It

Sure, they’re not exactly the sexiest body part, but it’s fair to say that life with substandard ear health would be notably less enjoyable. And as it happens, millions of Americans would be able to speak to that.

Research indicates that an estimated 1 in 5 folks have some form of hearing loss. This rate increases to 1 in 3 for age 65 and over, but some estimates put hearing loss great enough to impair communication even higher for the upper decades at around 40%. Perhaps even more alarming, close to 15% of American kids have some form of hearing loss. In teenagers, prevalence has jumped from 15% in 1994 to almost 20% in 2006. Unfortunately, that hearing difficulty will often go undiagnosed.

Hearing loss is, in fact, the third most common health condition in the country, right on the heels of arthritis and heart disease. And it’s getting worse. Between 2000 and 2015, the number of Americans with hearing loss has doubled, mirroring a worldwide increase of 44% over that same period.

But it’s not all about hearing. What about ear health? Our ears perform plenty more functions than just auditory reception. Let’s not forget that the ears are instrumental in influencing our emotions and state of mind, maintaining our sense of balance, and regulating pressure.

The Secret to Athletic Longevity

Today’s guest post is written by Tim DiFrancesco, PT, DPT, ATC, CSCS, Head Strength and Conditioning Coach for the Los Angeles Lakers and owner of TD Athlete’s Edge. Tim is a longtime friend of the Primal community, and I’m thrilled to have him contribute today. He’s offered to lead us through a portion of the screening he uses to evaluate players as well as exercises to improve weaknesses. I think you’ll find a great deal to apply to your Primal fitness in the tips and demonstrations.

How to Feed, Train and Care for Your Cartilage

Most health and fitness writers don’t spend a lot of time on cartilage. As tissues go, it’s fairly isolated. It doesn’t contain blood vessels, so we can’t deliver blood-borne nutrients to heal and grow it. Cartilage has no nerve cells, so we can’t “feel” what’s going on. Doctors usually consider it to be functionally inert, a sort of passive lubricant for our joints. If it breaks down, you’re out of luck, they say.

But that’s what people used to think about bone, body fat, and other “structural” tissues: that they are inert rather than metabolically active. The truth is that bone is incredibly plastic, responding to activity and nutrition, and that body fat is an endocrine organ in its own right, secreting hormones and shaping the way our metabolism works. What about cartilage? Can we do anything to improve its strength and function?

Dear Mark: High-Fat Diet, Gall Stones, and NAFLD

For today’s edition of Dear Mark, I’m answering two questions. Both concern the gallbladder. First, how does a high-fat ketogenic diet relate to the presence of gall stones? Can the former cause the latter? Or is the story a bit more complicated than that? Then, I discuss which fats are most amenable to the gall bladder-less. Also, where does non-alcoholic fatty liver disease, or NAFLD, come in?

How to Deal with Chronic Pain: Psychological Causes and Treatments

We like instant gratification. Who doesn’t? You desire a thing, you want it as soon as possible. This is entirely rational. The food looks good, you’re (relatively) hungry, so let’s eat. That gadget would be fun to play with, you’ve got the money (or credit) for it, so let’s buy it. This is why we sign up for and can never relinquish our Amazon Prime same-day shipping, why we demand antibiotics for viral infections, and why we can purchase and collect entire buckets of fried chicken without ever leaving our cars. We don’t like to wait if we don’t have to. And we rarely have to wait. This extends to how we deal with physical pain: my arm hurts, I want this pain to go away right now, so I’ll take a painkiller.
