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...

5 Non-Dietary Factors That Influence Your Microbiome

The microorganisms that reside in, on, and around our bodies influence almost every facet of our well-being. Part of maintaining microbiome health is maintaining homeostasis. Another is supporting diversity.
Our goal, then, is to improve our microbiological real estate in the many areas of the body that commensal and symbiotic bacterial like to put down roots—the gut, mouth, lungs, skin, reproductive organs, and so on. The average Primal enthusiast is well-versed with the role of food choices and smart supplementation (although research is always uncovering new wrinkles—more on this to come). 
I thought I’d give a little attention to some of the other basic practices that can influence microbial diversity and homeostasis. There are more answers and nuances than I can cover today, but let’s start with some of the fundamentals.

Dear Mark: When Nature is Stressful and How to Use Fish Sauce

For today’s edition of Dear Mark, I’m answering a couple questions from readers. First, is nature always relaxing and blissful? Or are there instances where being in nature is far more stressful than being indoors? Why, and what should we do about it? Second, how do I use fish sauce, and how would a parent use fish sauce to get picky kids to try (and like) new foods?

Let’s go:

Salmon with Pistachio Pesto

This dairy-free pesto is heavy on pistachio nuts and light on basil. Spiked with garlic and lemon zest and blended together with olive oil, this is a thick, rich sauce that’s more than a little addictive. It’s tempting to eat this pistachio pesto with a spoon, but it’s even better slathered over fatty, pan-seared salmon.

This recipe couldn’t be easier, and it magically transforms a simple salmon dinner into something extra special. Make this, and you’ll feel like a talented chef instead of a home cook who’s stuck in a rut of salmon dinners that are just ho-hum.

CrossFit’s Criticisms: How Do I Keep Energy Levels High on Primal?

Over the past two posts in this series, I’ve explained how a Primal way of eating can not only support a heavy CrossFit schedule, but elevate it. Today, I’m going to explain how going Primal can help fix a common complaint among CrossFitters: fatigue. No energy. No pep. A distinct lack of physical and psychological motivation to train, let alone hit PRs. This doesn’t just make it hard to finish workouts and make gains. It bleeds into the rest of your life and makes that worse, too.

The Definitive Guide to Children’s Nutrition

Feeding infants is quite simple. There’s a ton riding on you getting it right, of course—a developing immune system, the fact that the kid’s growing an inch a week, a permeable blood-brain barrier, synaptic pruning—but the answer is usually always “feed them more breastmilk.” Even if you can’t nurse, you’ve got formula, which, for all its limitations, is a decent proxy for breastmilk and getting better all the time. Feeding children, however, is a different ballgame altogether.

I’ve gotten a lot of requests for a post about children’s nutrition, so it’s long overdue. When it comes down to brass tacks, kids really are just small people. They aren’t a different species. They use the same nutrients their parents do. They need protein, fat, and glucose just like us. So in that sense, feeding kids is simple: Give them all the nutritious foods you already eat and know to be healthy.

But it’s not easy.
