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...

Dear Mark: Japan and Meat, Circadian-Friendly Nightlights, Barefoot Hiking Tips

For today’s edition of Dear Mark, I’m answering three questions from readers. First up, what was my main takeaway from the “Japan and meat” video posted last week? Second, are there any circadian-friendly nightlights—ones that don’t negatively affect our natural secretion of melatonin or disrupt our circadian rhythm? And finally, what are my tips for barefoot hiking? How can someone get their feet acquainted with the natural ground, deal with sharp rocks and gravel, and learn to enjoy their barefoot experience in nature?

Let’s go:

Dear Mark: More Embracing Your Wildness

Last week’s Q&A about cultivating wildness was a lot of fun, but there were some questions I didn’t get to in the original post. Today, I’m going to answer some more. From stirring stories of a father and son pursuing and living their dream after experiencing extreme tragedy to how to go barefoot more safely to the balance between creativity, progress, and Primal values to accepting the reality (and beauty) of having work to do to the value of sun exposure in winter to circadian entrainment. In short, we’re covering a ton of ground today.

The Plight of the Modern Foot: Conditions that Plague Us—and How to Avoid Them

For all the focus on hearts and arteries, brain tissue and muscle mass, we tend to neglect one critical part of the body with dramatic influence over how we fare in later decades. It’s little surprise really. Feet don’t exactly garner much attention, let alone media time. Yet, the stakes are big.

For example, research shows that foot conditions like hallux vagus (HV, a common forefoot deformity in older people commonly referred to as “bunions”) was directly associated with marked decreases in quality of life. Foot pain, reduced foot function, lowered social capacity, and even degraded general health. That sort of thing.

But that’s just one foot condition, right? Yes…and no. The picture of averages looks rather bleak.

Why What You Walk (or Run) on Matters

I’ve always preferred traversing natural surfaces. Growing up in New England, I developed my cross country running chops actually running across the country surrounding my house. My favorite endurance events were those involving trees and trails to the point that I might still be doing them if they were exclusively nature-based. Even today, I cherish my hikes through the Malibu hills and rather begrudgingly go for neighborhood walks only because the sidewalk is so convenient. Walking on flat, linear, manmade surfaces is certainly fine, especially if I’ve got my wife or dog or a friend?or I’m exploring a new city?but naturally deposited ground full of dips and peaks and studded with random deformations is ideal.

And there’s growing evidence that it’s better for you, too.

9 Ways to Restart Your Primal Lifestyle

It happens to the best of us. You start sneaking a few more bites of bread when out to dinner and trying your buddy’s delicious-looking pizza. Your workouts trickle to once a week, sometimes none. You walk less, couch more. And then one day, you realize you’ve gone off the wagon. You’ve gained belly fat. You’re getting winded going up the stairs. Your once-pleasurable hikes have become grueling affairs that you dread and end up avoiding. Your fridge is full of takeout boxes and you realize you haven’t cooked in two weeks. You need to restart your Primal lifestyle, and fast.

How do you do it?

Turns out there are more than a few ways that you probably haven’t considered. Let’s explore them:

5 Reasons to Run Outside Instead of on a Treadmill

Let me get this out of the way: treadmill running is better than sitting on the couch reading blogs that outline the reasons running outside is better than running on a treadmill. If it’s your only option – or even just the way you prefer to exercise — have at it. You have my blessing. The best exercise is the one you’ll do, remember. But there are limitations, risks, and biomechanical changes that occur when treadmill running. It’s not the same as running outside, and there’s evidence to suggest it might be worse in some respects.

So let’s explore the potential problems associated with treadmill running:
