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...Tell Me More
I’ve been lucky enough to travel to interesting places. The trips I’ve taken in the last 10-15 years, during my “Primal period,” have been the most meaningful, rewarding, and downright enjoyable because I’ve been able to view other cultures and customs through the prism of health, nutrition, and human evolution. I bring something back every trip—a tip, an insight, an alteration of an existing conviction. Travel abroad isn’t just a good time. It’s educational.

While I don’t recommend making Primalized versions of grain-based foods a staple, the fact remains that people love them. They’re going to want them. There’s not much you can do about that. And if we want to incorporate pancakes, muffins, cookies, and other flour-based items into our diets without ruining everything we’ve worked toward, we need the healthiest, most Primal flours.
The alternative flour market has exploded in recent years. A decade ago, you had gritty almond flour and fibrous coconut flour, and that was about it. Today, there are many more flours to sift through. But what are the best ones? Which ones fit best into a Primal way of eating, and why?Read More
Wheat gets a bad rap in the alternative health sphere, receiving blame from all sides. Today, I’m here to provide the other side. Today, I’m going to give you seven solid reasons to love wheat, ranging from its effects on the environment, its role in the foundation of the American republic, its effect on gut bacteria and your health, its ability to stamp out hatred, its protective role in the lives of Bronze Age Chinese women, and its status as an enduring symbol of human rights and prosperity.
Let’s get right to it.Read More
For today’s edition of Dear Mark, I’m answering two questions from readers. The first one concerns the reduction in testosterone men experience with marriage. Is it a feature? A flaw? Is it inevitable? After that, I get into a pair of new studies that question the safety of gluten-free diets in the absence of celiac disease. Is your gluten-free diet going to kill you?

First, non-celiac wheat/gluten sensitivity was a sham and everyone claimed its participants were in a collective mass delusion. Then some actual studies came out, and it appeared to be a real condition. Soon after, researchers offered different theories. Maybe it was FODMAP intolerance. Maybe it was all that wheat fiber messing up the gut. Maybe it was too little fiber and other fermentable substrate, and we were actually starving our gut bugs and compromising our intestinal health. Maybe it wasn’t even the gluten. And maybe it was actually some kind of a placebo. One of the most recent findings was that gluten sensitivity might not even exist. What’s the truth?Read More
For today’s edition of Dear Mark, I’m answering two reader questions. First, I answer a very specific question about blackstrap molasses, that nutrient-dense sweetener with the distinctive taste. How can a person who hates molasses work it into their diet? Next, I address concerns surrounding a set of healthy whole grain studies that I’m sure you’ve been hearing about. Are whole grains really healthy? Will they make you live long and prosper? Is there something unique to whole grains we’re missing out on?

For today’s edition of Dear Mark, I’m answering three questions from a single reader who just read an article from Vice. The article makes pretty bold assertions about topics that have already received a good deal of attention here on the blog. First, are probiotics actually useless? A new study cited in the article seems to suggest so. Next, is your gluten-free diet killing you? That’s what the author of the Vice article says. And finally, have GMO foods been conclusively proven to be safe and indistinguishable from non-GMO foods? Is the debate, more or less, conclusively over?
Let’s discuss:Read More
The other day it occurred to me that we’re coming up on 10 years with this blog. In 2006, I started publishing (what were then) wacky, newfangled ideas about how people should go barefoot (or wear Vibrams), eat more animal fat, slash carbs and eschew grains altogether, avoid (most) vegetable oils, stand up while they work, expose themselves to cold, get off the chronic cardio wagon and climb trees or sprint down their streets like 9-year-olds. Finally, there was the proverbial (and ironic) icing on the cake of suggesting people ask what would Grok do—that now illustrious posterman for all things evolutionary. Ten years ago many of these ideas were still viewed as strange or even flat out wrong.Read More
For today’s edition of Dear Mark, we’ve got four questions and four answers. First up, there’s a new whole grain study, and some people are claiming it demonstrates that low-carb diets will lead to early mortality. Does it do anything of the sort, or is this yet another flawed observational paper? Next, a teen on top of his diet game who hopes he’s doing it right writes in with a list of questions. I answer them. Next, what can a person recovering from a broken leg do in the way of sprinting? Or should she just focus on recovery? Finally, a wild and free man is roaming California with three pack mules, flouting convention and leading a nomadic existence. Police are occasionally called and media attention is often attracted. What are my thoughts?

In just about every article discussing the growing popularity of gluten-free diets, an expert or two appears three quarters of the way down warning about the “dangers” of attempting a gluten-free diet without medical supervision. The first reaction – from people like you and me who have experienced real benefits giving up gluten-containing foods – is a strong eye roll. “This again?” you think. Next they’re going to say that refined sugar is an important food group and I need a high-carb diet for “brain function” or something similarly inane.
But hey, these are medical experts with acronyms after their names. Maybe we should listen to what they’re saying and investigate their justifications for saying it. What dangers or risks are they actually referring to? Are they real dangers that we should heed, or are we in the clear?
There appear to be three primary arguments against widespread adoption of gluten-free diets. Let’s examine the evidence for and against each.Read More
