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...

Omega-3 for Health: What the Latest Research Shows

It’s been a long time since I published the Definitive Guide to Fish Oils.

Oh sure, here and there I’ve cited some research supporting the beneficial effects of fish fat, but it almost goes without saying that omega-3s are important. Everyone knows it. Even the most curmudgeonly, conventional wisdom-spouting, statin script-writing, lifestyle modification-ignoring doc will tell you to take fish oil. And research in the last few years has not only continually confirmed the health advantages but illuminated new applications—and new physiological explanations—for their essential function in the body.

But what are those benefits, exactly? Why should we be eating fatty fish or, barring access to high quality edible marine life, taking fish oil supplements?

What Causes Slow Post-Workout Recovery—and What Can You Do About It?

One of the biggest mistakes I see among people who exercise is they forget this core truth: we get fitter not from training, but from recovering from training. This doesn’t just occur in beginners either. Some of the most experienced, hardest-charging athletes I know fail to heed the importance of recovery. Hell, the reason my endurance training destroyed my life and inadvertently set the stage for creation of the Primal Blueprint was that I didn’t grasp the concept of recovery. I just piled on the miles, thinking the more the merrier.

It didn’t work.

A Primal Primer: Lymphatic Health

I get more questions these days about lymphatic health—particularly lymphedema. Sometimes it’s an issue related to a reader’s cancer recovery or a co-occurring symptom seen with a loved one’s other health concerns. While I might take up specific conditions in future posts (let me know if you have suggestions there), I thought I’d spend today taking apart the basics of lymphatic health. As with many of the body’s core operating functions, the real story often gets camouflaged within vague, consumer-based terms that end up being only medically tangential. Consider today’s post a trip into the weeds and (maybe) the beginning of an ongoing conversation on the topic.

The (Maybe Not So) Definitive Guide to Cold Therapy

Cold is really catching these days. Aubrey Marcus, whom I recently filmed a nice podcast with, was asked about his winning daily behaviors on another show. The very first thing he mentioned was “exposure to cold.” His practice is finishing his morning shower with a three-minute stint at full cold setting. He mentioned the hormonal benefits but also the mental edge he gets from psyching up and accepting the challenge instead of wimping out. He also cited research that people who engage in therapeutic cold exposure catch fewer upper respiratory infections. Hence, like many other elements of conventional wisdom, the old wives tale is backwards. Of course, we are talking about acute and optimal duration cold exposure, not prolonged exposure to elements that weaken your resistance and contribute to immune disturbances.

As with keto, there’s much more to be learned in this burgeoning field before we can operate in definitive (hence today’s title). Today, however, I’ll expose you (the first of more double entendrés to be on the lookout for) to important concepts and best practices so that you may enjoy the vaunted benefits and avoid some of the negative effects of going about cold exposure wrong.

Is the Autoimmune Protocol Right For You?

If you think going Primal is restrictive, the autoimmune protocol is downright draconian. But this is by design. The entire point of an autoimmune Primal/paleo protocol is to eliminate all the foods with the potential to trigger any allergenic, autoimmune, or inflammatory responses. That leaves out a lot of delicious foods, many of your favorites—but it can be a powerful way to assess your sensitivities, target the root causes of mysterious health problems, and illuminate a path forward. It gets you back to square one. A fresh start, a wiped slate.

Primal Action Point: The Mind-Body Connection & Thyroid Health

“I became aware of the power of positive thinking after solving my first bout of hypothyroidism. So when a Reverse T3 problem showed up, I actively filled my life with audiobooks, podcast interviews, and films related to spiritual healing, the power of positive thinking, and the power of the subconscious mind.

Make a vision board to hang in your house, or make a smaller version that you can keep private if you don’t want others in the household to see it. Devote the entire vision board to health and healing; it can be a continual source of inspiration and hope while also imprinting your subconscious mind with positive health affirmations every time you see it.

If you are experiencing hypothyroidism for the first time, just know that it is fixable. You have the highest chance of success if you dedicate yourself to learning all that you can about hypothyroidism while adopting a paleo/primal eating and lifestyle strategy to support your goals.

Introducing The Gut Healing Protocol—With a Don’t Miss Deal!

Greetings readers, as you know, gut health has become the hottest of topics in ancestral health circles, and is also getting increased attention in mainstream medicine. More and more science is validating how a healthy gut microbiome has wide-reaching impact on general health, and that a damaged gut can set you up for all kinds of downstream health challenges. There are several helpful primers on gut health published here (1, 2, 3).

Today’s message, however, is something a little different and more personal. It comes from a dynamic young health expert from Australia named Kale Brock. We are pleased to bring his wildly popular grassroots gut health book, The Gut Healing Protocol: An 8-Week, Holistic Program to Rebalance Your Microbiome, to the U.S. market. Kale became an expert on gut health not from formal medical training, but rather the hard way. Like many thought leaders in the ancestral health community, Kale’s obsession with gut health was triggered by a serious health setback that was poorly addressed by traditional medicine.

Dear Mark: New Coffee Study, Letting a Fever Run its Course, Collagen Dosage

For today’s edition of Dear Mark, I’m answering three questions from readers. First, I give my take on a new, big coffee study, which analyzed several meta-analyses of existing coffee and health data. Second, should you let a fever run its course or try to defeat it at all costs? The body obviously “wants” to get hotter in these situations. Is there a good reason? And finally, how much glycine do people need per day?

Let’s go:

Dear Mark: Is Keto Ancestral, Ketone Breath, and Keto for Lupus?

For today’s edition of Dear Mark, I’m answering some questions about keto (hey, you folks keep asking!). First, is being on a ketogenic diet actually congruent with our ancestry? Is there historical precedent? Next, is bad breath really a reliable indication of being in ketosis? And finally, could going keto help treat the autoimmune disease lupus?

Let’s take a look:

More on Adaptogens: Ashwagandha, Astragalus, and Holy Basil

Last week I waded into the adaptogen theme, examining the many ins and not-so-many outs of American and Asian ginseng. It got me thinking—why not keep the ball rolling? The ginseng varieties I mentioned are only two among many adaptogens after all.
Let’s dive right in and take up three additional adaptogen choices—along with some additional suggestions for discerning the safest and most potent formulations.
