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.

7 Primal Mantras to Drive Your Success

Do you have any mantras? You should.

Ignore the pseudo-spiritual baggage many people have with the notion of a mantra. Repeating and focusing on a meaningful phrase to help guide you through difficult situations, whether that’s an hour of sitting meditation or a commitment to a healthy Primal lifestyle, is a legitimate tool anyone can use. Today, I’m going to give you 7 mantras that I find to be useful.

Many of these don’t even apply explicitly to nutrition or fitness, so anyone can gain from incorporating them. I even left off a personal mantra of mine—”Rend the flesh of young mammals and consume it close to raw as possible”—to make vegetarians and vegans feel more welcome.

The Empathy Effect: How Befriending Your Future Self Can Impact Your Health Today

You are not the person you were fifteen years ago. The cells that compose your tissues and deliver oxygen have been recycled many times over. Your face has changed. You move differently. You’re probably slower and weaker, or, depending on your daily habits, faster and stronger. As it becomes available, you incorporate new information into your belief system. Even the neat narrative we imagine we’re orchestrating unbroken in our heads has nightly intermissions lasting hours during which we have no real clue what happens.

Is this all just philosophical navel-gazing better suited for 2 AM in a dorm room covered with Bob Marley posters? Not exactly. Accepting the idea that past and future selves are different people can have real benefits today—and tomorrow.

Dear Mark: Infrared Sauna Roundup

After last week’s post on infrared saunas, people asked some good questions. For today’s edition of Dear Mark, I’m answering a few of them. First up, can infrared saunas harm male fertility? After all, they do penetrate the skin and raise body temperature, which is a no-no for sperm. Next, infrared saunas induce lots of sweating, and sweat contains bioaccumulated toxins like BPA and heavy metals. Can infrared saunas help us shed these toxins? Finally, are infrared-emitting blankets and other “topical” infrared products effective alternatives to infrared saunas?

Are Infrared Saunas Beneficial?

Last month, I installed an infrared sauna in my house. A company offered it to me to try out, and I was willing to give it a go, knowing a little about them already. It also inspired me to dig into the research—to test it personally but also to see what studies had demonstrated in terms of benefits. I’ll say I’ve been pleased with what I’ve found from both angles.

Over the past few weeks, I’ve been following a new bedtime ritual: a half hour in the sauna, a cold plunge in the pool, bed. The reasoning is that after warming up my tissues in the sauna, I drop them back down to prepare for sleep. So far, it’s working. I wasn’t exactly starting from a deficit—my sleep has been consistently good ever since I changed how I consume alcohol—but I’m really happy with the new setup.

Why infrared?

A traditional sauna heats the air around you. An infrared sauna uses infrared light to penetrate your skin and warm you directly without affecting the ambient temperature. This makes them great for home use.

How to Move through Life with an Edge

Every former competitive athlete’s worst nightmare is that moment when you lose to a younger person doing the sport you love. When the cocoon of invincibility and superiority you’ve erected around yourself comes crashing down and a piece of your self-identity shatters. It can truly feel like the end.

I know the feeling. Several years ago on a family ski trip, my son challenged me to a downhill snowboard race. We’d been doing these races—and I’d been winning them—ever since he was old enough to board. It was tradition that we race, and that I win. It’s just how it played out.

This time was different. I was a newly minted member of the 6-decades club. He was a young man, fully grown, years of sports under his belt. He smoked me. It wasn’t even close. And suddenly I realized that despite being in the best shape of my life relative to my age, that upper limit was trending down.

8 Primal Food Challenges You Can Take

Humans are competitive animals. We like a challenge because it compels us to rise to the occasion, prove ourselves, get better at something, or become a bigger version of ourselves. For people, challenges are like hormetic stressors—they often cause suffering and require hard, unpleasant work but provoke a beneficial response that makes us stronger than we were before the challenge.

How does that apply to the challenges I’ve laid out in today’s post, which are all about food, diets, and cooking? Each one unlocks a tangible benefit (eating more vegetables helps you obtain more nutrients, stopping the meal before you’re too full lowers energy intake), but there are also less obvious benefits to meeting a challenge.

Let’s get right to it:
