The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate in...
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
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?

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.Read More
Go back 160,000 years and we all share a common ancestor: The emergence of the first Homo sapiens in East Africa. Since then, humans have spread across every environment imaginable and adapted to those environments. Much remains the same. We all breathe oxygen, require protein, produce insulin, oxidize fatty acids. But extended stays in unique environments have created genetic proclivities in different populations. For example, descendants of people who settled in high-altitude areas like the Himalayas, the Andes, and the Ethiopian highlands tend to show greater resistance to low-oxygen environments, while the Greenland Inuit show unique adaptations to cold environments, including increased activity of heat-stimulating brown fat. And among the island-dwellers of Sardinia, where the landscape constrained the amount of available food, there’s considerable evidence of positive selection for short stature.
What other differences exist, and how can we explore them to inform and improve our own diet and lifestyle choices?Read More
Prior to 1980, how in the world did anyone know how to eat? When you think of all the centuries, the millennia of human existence, how did the species manage to survive bumbling their way through day after day of undirected eating patterns? I’m guessing those of you who know me expected a few irreverent remarks when you read the title of today’s post. Still, I’ll try to keep myself on a short leash today. It’s a legitimate and even, in some regards, culturally (and probably politically) significant question: why were government dietary guidelines ever put in place—and what was the backstory of their uses and modifications over time? Finally, what perspective can it bring to our understanding of embracing a “niche” dietary model like the Primal Blueprint?Read More
Print this out. Bookmark it. Send it to friends who don’t quite get the Primal thing. Consider this a valuable resource for all-things Primal. It’s a nice, alphabetical encapsulation of what it means to lead a Primal lifestyle. It’s not everything, of course. You can always dig deeper into the details, but this summary gives a high-level look at just about everything.
Without further ado, I present The A-to-Z Guide to Leading a Primal Lifestyle.
Avoid chronic cardio. I spent about half my life running (and later, with triathlons, swimming and cycling) myself into the ground. I thought the more miles I could log, the healthier I’d be. That’s the mindset many people have, and it’s absolutely wrong. Running a ten-miler is different than running a ten-miler every day. We have the capacity to go long distances and even outlast wild animals upon which we’re preying. We don’t have the capacity to do that every single day without consequences to our health. Run long distances if you love it, compete if you love competing, but know the cost it incurs.Read More
Some foods and flavors are just made for one another. Bacon and eggs. Strawberries and cream. Basil and tomato. Oil and vinegar. Sweet and sour. The list goes on and on. But what’s behind these classic and nearly universal combinations? Does taste alone drive the decision to, say, add fresh herbs to a charred piece of meat? And if pairings are driven by taste, which sounds reasonably, could it be possible that healthy pairings naturally taste better because we’ve evolved an innate draw towards these powerful combinations? The jury may still be out on that one. Nevertheless, some foods, when taken together, make surprising nutrition sense.
Let’s take a closer look.Read More
