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...

Primal Camping Meals: Weekend “Car Camping” Edition

Most camp food is terrible or the opposite of Primal. Or both.

It’s either an expensive REI tetrapak full of wheat flour, dehydrated “meat,” and desiccated Crisco, a Dough Boy, or the entirely overrated s’more. I’ll get flak for that last one, but I don’t care. S’mores rarely live up to the hype past age 12.

Just because you’re living out of a tent doesn’t mean you have to settle for terrible, unhealthy, unappetizing food. If anything, you should be eating healthier when you camp. It feels corrosive to defile the sanctity and purity of the wild with processed junk food wrapped in plastic. You generate all this trash. Whole, Primal foods taste even better when you camp; packaged garbage somehow tastes even worse.

Dear Mark: Choline Supplementing, Too Many Almonds, Keto and Insulin Resistance, and How to Drink

For today’s edition of Dear Mark, I’m responding to four reader comments. First up, if a person can’t eat eggs, doesn’t like liver, but really wants choline, can they just supplement? Second, are a couple handfuls of almonds too much omega-6 for the average person? What if they eat fish? Third, a new study claims to show that keto dieting tanks hepatic insulin sensitivity. What should we make of it? Are we giving ourselves type 2 diabetes by going keto? And fourth, I highlight a great approach to drinking alcohol (and living in general) from one of our readers.

Let’s go:

Alcohol While Keto?

People like to get healthy, burn body fat, increase their aerobic capacity, and improve their cognitive function. The ketogenic diet is an excellent way to obtain those outcomes, which partially explains its meteoric rise in popularity. But people also like to drink alcohol. You might say it’s a toxin—I wouldn’t disagree. You might say we’d be better off without it—perhaps. The fact remains that people have been drinking for tens of thousands of years, and they’re not going to stop anytime soon.

Can keto and alcohol coexist? Is there anything we need to take into consideration?

First things first, does alcohol inhibit ketosis?

Dear Mark: Is Farmed Salmon Worth Eating?

For today’s edition of Dear Mark, I’m answering just one question from the comment section of last week’s omega-3 post.

It’s a short one, maybe one of the shortest reader questions ever, and it represents one of the few cut-and-dry stances in ancestral health. Humans are omnivores, seed oils are bad for you, no curls in the squat rack, and farmed salmon is toxic poison.

Right? Maybe not.

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?

Metabolism and Menopause: What Does Research Suggest Is the Best Dietary Strategy?

After my recent post on keto for women, I got a lot of feedback. One of the most common themes: “But what about menopause?” I heard from dozens of women in both the comment section and in emails who were having trouble losing weight and dealing with the varied symptoms of menopause. Was keto the answer? Was Primal? Were they doing something wrong?

Rather than start with the assumption that going keto or Primal is the best way to deal with menopause, I figured I’d start from ground zero, drawing on the extensive scientific literature on diet and menopausal symptoms to see if I could arrive at some general trends and make recommendations.
