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...

What Does the WHO Report Mean for Your Meat-Eating Habit?

I’m sure you’ve seen the rash of fear-mongering headlines proclaiming red meat to be as carcinogenic as smoking. In fact, I know so because dozens of you have asked me for my thoughts. What’s going on? Do we need to worry? What actually happened? Why have your vegan friends become even more smug than before? Why did your crazy aunt send an email in all caps pleading for you to stop eating “so much beef”?

Citing a short summary paper of a much larger study, earlier this week the World Health Organization (WHO) named processed meat a definite human carcinogen and red meat a probable human carcinogen. That’s frightening at first glance. I mean, the WHO? Great band, weren’t quite the same after Keith Moon died, but for my money they’ve always delivered quality health information. When they issue a report about dietary carcinogens, I listen up.

Dear Mark: Ketosis and Testosterone, Dehydration Hormesis, and Isomalto-Oligosaccharides

For today’s edition of Dear Mark, I’m answering three questions. The first one concerns a potentially combative and controversial topic: ketogenic diets. What’s the deal with their effect on testosterone? You can find keto anecdotes across the web both inspiring and flaccid, but what, if anything, does the science say? Next, might there be a way to derive beneficial hormetic effects from acute bouts of dehydration? It seems like every other stressor can actually make a person stronger, so perhaps an otherwise wholly negative one like dehydration might as well. And finally, is the prebiotic fiber known as isomalto-oligosaccharide safe and/or good to eat?

Dear Mark: Exercising (and Eating) in the Heat; Post-Antibiotics Gut Health Support

For today’s edition of Dear Mark, I’m answering a pair of questions from you folks. First up, what with the crazy heat wave sweeping much of the planet, a reader writes in asking about the best way to eat and move in the heat. Should you cease all activity? Should you modify your normal movement patterns and eat and drink differently to keep the heat at bay? Read on to find out. Next, how should a person deal with and support the post-antibiotics gut biome? What can we do to mitigate the negative effects broad-spectrum antibiotics have on our gut bacteria?

How to Take Care of Your Gut: The New and Improved Primal Flora

Anytime I discuss supplements, some readers balk. For them, if Grok didn’t do it, we shouldn’t either. And you know what? If that describes you, I get where you’re coming from. Ideally, optimal health develops organically — from the food we eat, the sun, sleep, and movement patterns we follow, the lifestyles we develop. But we don’t live in Grok’s world any more. We don’t have access to the same nutrient-dense plants and animals he did, and we face entirely new stressors and endure novel deficits previous generations never have. These new challenges call for new solutions, and supplements can be one of these solutions. As a supplement maker, I always take cues from Grok’s behaviors, physiology, and requirements and use modern day science to produce quality products. I’m not just making them to sell something. I’m meeting a need and filling a deficit. Usually my own!

Dear Mark: A New Whole Grain Study, Advice for a Teen, Broken Leg Sprints, and The 3 Mules

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?
