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...

CrossFit’s Criticism: How Do I Eat Enough Carbs on Primal?

By far the single most common criticism levied against paleo by CrossFitters is that it’s too damn difficult to eat enough carbs to maintain performance during workouts. There is definitely truth there.

First, let’s establish something. Do CrossFitters indeed need more carbs than your average Primal bear?

Yes.

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?

Let’s go:

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.

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.

Adaptogen Effects: American and Asian Ginseng

I’ve been using adaptogens for quite some time, but in the last year I’ve been experimenting a little more with them. You may have caught my mention of a few adaptogenic varieties in one version of my daily big ass salad (not for a flavor hit). I’ve also briefly highlighted ashwagandha and holy basil, and I’ve always been a big believer (and user) of Rhodiola rosea for normalizing stress response.

All well and good. But what’s the backstory on adaptogens? What is there to gain? And what about the other options?
