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...

12 Essential Tips for Primal Women

Look: I’m a man. I’ve lived a different experience than the average woman, with totally different equipment and different concentrations of hormones coursing through my body. But I have a daughter and a wife and a good head on my shoulders that’s spent the last 30 years thinking about health, nutrition, and fitness for humans, so I have a few things to offer.

So let’s get right down to today’s post. What follows are 12 tips for Primal women. Or any woman, really.

(Men, too: if some of the things mentioned in today’s post aren’t working for you, and the tips seem to apply, go for it!)

8 Primal Rules for Building Better Bones

Strip away the skin, fascia, muscles, organs, blood vessels of a human and you’re left with the bones: the foundation providing passive structural support. Many people accept that we can affect and even control the health of the rest of our tissues. Muscles? Just lift. Cardiovascular system? Do some cardio and lose weight. Teeth? Stop sugar. But bones just wear down the older you get. Everyone knows it. And sometimes bones just break. There’s nothing you can to prevent it and nothing you can do to improve your healing except wait and hope. If you want stronger bones, you’ll need some pharmacological assistance provided by a white coat-clad adult wielding a prescription pad.

But bones aren’t inert. They are living metabolic tissue. And though we can’t tell them what to do directly, they grow—or diminish—in response to the signals we send. What kind of signals should we be sending?

Top 16 Tips for the Perfect Primal Vacation

When most people think about the perfect Primal vacation, they’re thinking about camping, rock climbing, surfing, trekking, scaling mountains, fording rivers, and generally being out in nature. There’s some truth to that. Natural beauty abounds all over this world, and most folks following the Primal Blueprint have a deep-seated appreciation for the natural world. However, being Primal is about far more than just diet, exercise, and being outside. Those may get most people through the door, but the movement has grown and my thinking has evolved to encompass a wider range of qualities and sensibilities. As Primal travelers, you are exceptionally thoughtful. You value experiences over things, and the things you choose tend to enhance life experience, not replace it. Your vacations should be no different.

So these are my top tips for engineering the perfect Primal vacation. Coincidentally, they’re great tips for anyone looking to have a memorable, transformative experience in a new place.

Dear Mark: Baby Sleep/Feed Schedule and Walking Through a Sedentary Society

For today’s edition of Dear Mark, I’m answering two reader questions. The first comes from reader Larisa. She is about to give birth, has been hearing the “wake your newborn every 2 hours to feed” recommendation, and wonders how realistic, evolutionarily-congruent, and healthy that will be for new parents desperate for sleep. I offer a few loose recommendations that hopefully make her feel better about what’s about to descend upon her life. Second, is there such a thing as too much low-level activity? Mariel walks 10+ miles a day, strength trains, and stands when she gets tired of walking. Her coworkers think she’s crazy. What do I think? Find out below.

Dear Mark: Do Hunter-Gatherers Sleep Less Than We Thought?

For years, we’ve thought that hunter-gatherers slept like babies: long and hard. They’d drift off as the sun dropped, lingering around the ubiquitous campfire only for a short time, sleep a good 8-10 hours, and waking up at first light bright eyed for the next day. For today’s edition of Dear Mark, I’m examining a study that calls these assumptions into question. What if hunter-gatherers don’t actually sleep any more than us? What if the absence of artificial light doesn’t lead to a ten hour session of blissful repose under the stars?
