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...

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.

Collagen for Skin: The Truth Behind the Benefits

It’s easy to get into the habit of assuming that certain things “just happen” as we get older. As the years pile up, we brace ourselves for brittle bones, expanding waistlines, failing eyesight—and a propensity for falling asleep in front of the T.V.

Statistically speaking, they do loom largely. This is what we often see around us after all. But, of course, we know it’s not the whole story. We certainly can resign ourselves to a common fate, but that’s probably not why anyone is reading today. Most people who visit this blog (and definitely those who frequent it) want more. They want something better, and they’re willing to learn, move, and eat to get it.

And as with our bodies, so with our skin…

Should I Take a GLA Supplement?

Recently, a reader inquired about gamma linolenic acid (GLA) and inflammation. Is GLA everything it’s made out to be? Is it something all of us should add to our diets? Can we obtain it through real foods, or do we need to rely on supplements? There’s certainly a lot of hype about GLA’s ability to heal chronic inflammation and even to facilitate an easier transition into menopause (something I’ll cover more in a follow-up post). For today, let’s take a closer look at GLA and the role it may play in anti-inflammatory nutrition.

Hair Loss: Looking beyond Genetics

Conventional wisdom teaches us to accept our fate when it comes to hair loss. “Runs in the family,” we’re often told—and sometimes it does (but that’s usually not the full story). “It’s just part of getting older,” people say, too—and there we again find only partial truth at best.

But the Primal path is one of thoughtful scrutiny, not blind acceptance. While most people would file hair loss under aesthetic concerns (ranging from neutral to negative depending on social norms and personal views), it’s not always that innocuous. Let’s look today the bigger picture behind hair loss and the situations in which it signifies a genuine health concern.

Dear Mark: HDL, Probiotics for Acne, and Artificial Sweeteneners and Weight Gain

For today’s edition of Dear Mark, I’m answering three questions. First, is HDL all it’s cracked up to be? Is HDL always good? Is it the savior? Or is the story a bit more complicated? Next, what are some good probiotic options for treating acne? Do any exist? And last but not least, what’s the relationship of artificial sweeteners, insulin, appetite, and weight gain?

Coconut Oil Is Going to Kill Us All (or Maybe Not…)

I was beginning to rest on my laurels. It had been months since the inbox had flooded with upset readers asking me to address the latest episode of the conventional establishment’s attack on healthy food and living. Until last week, when people starting freaking out about the American Heart Association’s attack on coconut oil. As USAToday put it, “Coconut oil isn’t healthy. It’s never been healthy.”

I was surprised. While I get most of my scientific references from USAToday (the “Works Cited” section of my upcoming keto book is just a single link to USAToday.com) and they’ve never let me down in the past, I didn’t know what to make of their coconut oil claims.

5 Unconventional Ways to Extend Your Life

I’ve written about extending your life by slowing down the apparent passage of time. I’ve written about some interesting predictors—but not necessarily causes—of longevity, and the common characteristics of centenarians. Today, I’m going to describe several unconventional causal means of extending your life.

I’m talking about cold, hard days, weeks, and months. Ticks on a clock. Objective measurements of time. Not just the perception of time, although that matters too.

10 Reasons to Eat More Collagen

For years, the bodybuilding, protein-gorging community has maligned collagen for its inessentiality and lack of input into the muscle-protein synthesis process. From their perspective, it sort of makes sense. Why bother with “low quality” protein like gelatin/collagen when you can pound the whey, eat the meat, and focus on other sources of the essential amino acids directly involved in building muscle?

Except the research is showing that these “nonessential” proteins are actually pretty darn useful.

Dear Mark: Fat Gain on a Ketogenic Diet; Dandruff and an Itchy Scalp

For today’s edition of Dear Mark, we’ve got a two-parter. First up, I respond to a comment from last week’s Weekend Link Love concerning fat gain and lean mass loss in taekwondo athletes on a ketogenic diet. Did the athletes actually get fatter and lose muscle on their diet, even as performance improved? After that, I discuss what to do about dandruff and an itchy scalp. There may be no silver bullet against the common malady known as dandruff, but there are a few things you can try and one in particular that looks quite promising.

How to Support Healthy Skin Bacteria

Last week, I introduced the concept of the skin biome: the vast communities of microbes living on and in our skin. For some, it was unsettling. Gut microbes are out of sight, out of mind. But skin microbes are on us. They’re crawling, reproducing, digesting, and secreting various fluids and lipids all over the surface of our bodies. In people who’ve been conditioned to use soap and water to remove every last trace of bacteria from our hands and skin, the idea that our hands, faces, arms, and torsos are teeming with microbes – and that it’s probably unwise to remove them all – is hard to swallow. We might even recoil at the thought. I mean, viruses and mites living on us? Really?
