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...

Dear Mark: Fat Roundup

Last week, I wrote about my 16 favorite fats. You had questions. For today’s edition of Dear Mark, I’ll answer some of them. First, I explain why my keto salad recipe didn’t include any dense protein. Second, I explain a few options for steaming heavy cream. Third, I tell where I get my mac nuts. Fourth, I discuss whether you should worry about dioxins in pastured eggs. And fifth, I address the question of dietary fat and fatty liver.

My 16 Favorite Fat Sources (Plus My Latest Big-Ass Salad)

Going ketogenic has made me hone in on my fat sources even more than before. This is an essential practice for anyone seriously pursuing a ketogenic diet. As fat will comprise the majority of your calories, you need to maximize the nutrition you’ll obtain from the fats you choose. You could technically go keto using canola oil, refined coconut oil, and MCT oil powder—many of the ketogenic formulas used in epilepsy clinics are highly processed and refined—but I wouldn’t recommend it. Micronutrients still matter. They arguably matter even more when your food sources are restricted.

Mark’s Big-Ass Keto Salad

For years now, all those who know me (including readers of the blog) have heard me talk about my daily “big-ass salad.” It’s been my lunch of choice for a couple of decades at least, and I don’t see that ever changing. Over the years I’ve adapted it to my personal tastes, nutritional experiments, and—lately—my keto practice.

Some people minimize vegetable intake when they’re eating keto. I’ve never found that necessary or beneficial. In fact, I highly recommend plenty of above-ground vegetables and even berries for an optimally varied, nutrient-dense keto diet. That’s my Primal take because personally I practice keto with an eye toward strategy, not restriction.

Dear Mark: Red Blood Cell Fatty Acid Content and Obese Paleo Figurines

For today’s edition of Dear Mark, I’m answering a pair questions that, well, question some of the fundamental principles of Primal living and eating. First up concerns a study seeming to show that linoleic acid (from seed oils) is a healthier, less inflammatory choice than olive oil or fish oil. Could it be true? Find out below. Then, I discuss the existence of obese female figurines from the paleolithic as evidence of obesity in actual paleo populations. Does a doll with a belly mean the Primal way of eating, living, and moving needs to be reworked?

Grass-fed Vs. Conventional: When Does It Matter Most?

By now, you’re convinced of the general overall superiority of grass-fed, pasture-raised meat. If you come at it from the nutrition angle, grass-fed wins across the board. If you’re more concerned with the ethics of animal husbandry, grass-fed animals live overall better lives than animals in concentrated feedlots. If you worry about the use of antibiotics in agriculture and the rise of antibiotic-resistant bacteria, grass-fed animals receive less medication (and sometimes none). Whatever your inclination, animals who range free and nibble their biologically appropriate diet of various grasses tend to be happier, healthier, and produce more nutrient-dense meat, milk, and fat. It’s objectively “better.” Even an honest vegan will admit that.

But the stuff is expensive. I have the luxury of buying and eating solely grass-fed, pasture-raised meat and dairy, but not everyone can. Most folks have to choose. They have to pick their battles. Today’s post will help you choose wisely.

Dear Mark: Fasting Issues, Pullup Neck Pain, and Red Palm Oil

For today’s edition of Dear Mark, I’m answering three questions. The first one comes from Neda, who’s experiencing some issues that may be related to her fasting schedule. How should she modify her fasting? Or should she eliminate it altogether? The second question concerns a common issue: neck pain during pullups. Why does it happen and how can we avoid it? And finally, what’s the deal with red palm oil? I give my take on the controversial oil, drawing on randomized controlled trials and personal feelings about orangutans to arrive at my conclusion.

Dear Mark: Nutrient Deficiencies and Fatigue, Anxiety, CLA Supplements, and Plant-Derived Oils

For today’s edition of Dear Mark, I’m answering four questions from readers. First up, are there any specific nutrient deficiencies that can contribute to fatigue? Which minerals and vitamins should you shore up when experiencing malaise? Next, what’s the deal with anxiety? Does it serve an evolutionary purpose, or is it just a pathological condition? Third, is there a place for conjugated linoleic acid (CLA) supplementation in a healthy diet and lifestyle? I dig into the studies to help you decide. And finally, what plant-derived oils beside just avocado oil are good to use when staying Primal?

Dear Mark: Butter and Coagulation; Early Weaning and Growth Charts

For today’s edition of Dear Mark, we’ve got a quick two-parter. First up, I discuss the results of a 2008 study into the effect of high acute intakes of various fat sources on postprandial (i.e. after eating) blood coagulation markers. Since butter came out looking not so hot, a reader wonders whether this should impact our butter consumption. Find out what I think down below. And after that, I explore infant growth charts and early weaning from breast milk in response to a new father’s question about a doctor’s suggestion.

10 Principles of Primal Living That Are (Finally) Getting Mainstream Media Coverage

We don’t take credit for everything, of course, but the fact remains that the Primal/ancestral health community has been championing principles that directly oppose the conventional wisdom for nearly a decade. And while serious researchers have been paying attention to and studying these issues individually for years, no one had really synthesized them under the evolutionary umbrella. Now that our movement is becoming more popular and the scientific case for its principles more solid than ever, denying that a bit of sun might be good for you or that sitting is killing you slowly or that eggs aren’t deadly after all is no longer tenable.

Yes, Primal health principles and positions are getting mainstream recognition. Let’s take a look at some of the major ones.

Dear Mark: Palmitic Acid and Eating Speed

For today’s edition of Dear Mark, I’m discussing the seemingly evil qualities of palmitic acid, the preferred storage form of body fat in humans and many other mammals. Studies seem to indicate that pure palmitic acid has negative health effects, so should we be avoiding palmitic acid-containing foods like butter, meat, or palm oil? Then, I explain the health effects of eating really fast. As you’ll see, there are quite a few reasons to eat more slowly than quickly. I also include a few tips for fast eaters who want to slow down.
