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.

For today’s edition of Dear Mark, I’m answering some questions about keto (hey, you folks keep asking!). First, is being on a ketogenic diet actually congruent with our ancestry? Is there historical precedent? Next, is bad breath really a reliable indication of being in ketosis? And finally, could going keto help treat the autoimmune disease lupus?
Let’s take a look:Read More
The explosive growth of interest in the ketogenic diet has been a net good for the state of nutrition. For one, people have accepted the fact that eating fat won’t kill you, and they’re even getting clued into the benefits of eating it.
But there are places where I part ways with the popular keto movement.
Let me explain….Read More
Good morning, folks. With next week’s The Keto Reset Diet release, I’ve got keto on the mind today—unsurprisingly. I’ve had a lot of questions lately on duration. As I’ve mentioned before, a good six weeks of ketosis puts in place all the metabolic machinery for lasting adaptation (those extra mitochondria don’t evaporate if/when you return to traditional Primal eating).
But what about the other end of the issue? How long is too long? I don’t do this often, but today I’m reposting an article from a couple of years ago on this very topic. I’ve added a few thoughts based on my recent experience. See what you think, and be sure to share any lingering questions on the question of keto timing and process. I’ll be happy to answer them in upcoming posts and Dear Mark columns.Read More
A couple of weeks ago I sat down with entrepreneur extraordinaire, multi-sport athlete, and consciousness explorer, Aubrey Marcus, for an in-depth and entertaining discussion of everything from hangover cures to keto philosophy.
Marcus has always been one of my favorite people to talk with, and that morning in my backyard was no exception. We covered all things keto—from the mistakes people make in bottoming out their carbs instantaneously to the advantages of stair-stepping the process. I had a chance to share about my upcoming Keto Reset Diet book as well as personal details of my own experience with the keto state. Aubrey offered his latest favorite recipes (inspired by Primal Kitchen® products, no less!), and we talked in full but casual detail how keto dives set us up for genuine, lasting metabolic flexibility and overall health. There’s a lot of science and plenty of laughs here. I hope you enjoy, everybody!Read More
Keto is fantastic, everyone says. It’s a great way to lose weight, improve cognition, and stave off degenerative disease. It may help your performance in the gym and on the track. It could even give Grandpa some respite from Alzheimer’s.
But it’s hell on your thyroid. Right?
Keto detractors and proponents alike often warn that remaining in ketosis will tank your thyroid. The thyroid’s an important gland, exerting major influence over essential systems like fertility, energy, metabolism, body temperature regulation, blood lipids, and general wellness. It controls the metabolic rate of every organ in the body. We want it working well, so this is a major blow to keto—if the criticism holds true. Fortunately, there’s much more to this story.Read More
Gaining mass and building strength while CrossFitting should be a breeze. You’re lifting heavy things using compound full-body movements like squats, deadlifts, and presses, providing a potent growth stimulus to your muscles. Yet, many people fall short of their goals, perhaps losing weight and improving performance but failing to really gain any real muscle or strength.
Today, I’m going to explain how going Primal can help you achieve both goals.
First, you must understand the very Primal reality of your body’s hormonal systems and their relation to the environment: Acknowledge that you are an organism whose endocrine system is acutely attuned to the inputs it receives. It’s actively engaged in the world around you, making predictions and taking actions based on your perceptions. If your body thinks it’s living through a famine, it will conserve energy and eliminate wasteful extravagances like big muscles and 2x body weight back squat. If your body thinks it’s living through plentiful times, it will be more liberal with energy and allow the growth of extracurricular tissues, like big muscles. Create an environment of abundance—or even the impression of one—and you will be more likely to gain muscle and strength.Read More
