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...

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.

8 Primal Grilling Tips and Techniques

First off, let’s settle one thing right away. Grilling is not the same as barbecuing. Barbecue means big cuts of meat cooked low and slow. Depending on the animal, it can be an all-day affair with hours of preparation and plenty of leisure. In other words, it’s an actual event. With the time and labor intensity, barbecuing (as Michael Pollan put it so well recently) is the stuff of primal ritual, the site of social cohesion in our evolutionary story. Grilling, on the other hand, offers the smoke and fire experience without the bigger doings. While not as idyllic a prospect, it’s convenient. It means throwing a steak on the grill after work and eating it 20 minutes later. That’s the beauty of grilling. It’s relatively quick, requires very little clean up, and let’s you kick back outdoors while cooking dinner.

In order to relax, however, it’s good to be confident that dinner won’t go up in flames. Luckily, what separates someone who burns dinner from a real grill master is simply practice, plus a few tips and techniques.

Dear Mark: Low-Fat Beats “High-Fat”; Prunes for Bone Health

For today’s edition of Dear Mark I’m answering a pair of great questions. First, Vaughn asks me about a recent study where ethnic Chinese participants were placed on several different diets, and those on the “low-carb, high-fat” one actually did worse than those on higher carbs and lower fat. Should you give up your low-carb approach? Then, I explore the bone-strengthening effects of prunes and discuss the Simon and Garfunkel diet.

Let’s go:

RESEARCH OF THE WEEK

Preformed vitamin D, the kind found in eggs, fish, and meat, is about 5 times as bioactive as vitamin D3. This makes animal foods a rich source of vitamin D and may explain why human skin lightened after the adoption of agriculture—so they could replace the vitamin D they no longer got from hunted meat.

Deficiencies of carnitine (a nutrient found in meat) may explain some autism cases.

Some people may be overdoing vitamin D supplementation.

Given a prompt, airport visitors are more likely to walk than ride the people-mover.

Bacon Guacamole with Cheddar Chips

Guacamole is an easy sell. Put a bowl out at a party, and immediately the entire group is hovering over the bowl ready to dip in. So, imagine what might happen when a bowl of bacon guacamole is served. Stand back—this is a flavorful, high-fat snack that people are going to run towards.

Basic guacamole doesn’t really need a recipe. In essence, it’s just avocados, lime and salt. However, if your usual go-to has tasted a little ho-hum lately, this recipe will guide you back to an amazing bowl of guacamole. Ripe avocados are mashed with shallot, garlic, cilantro, lots of lime, and yes, bacon. Bacon is the perfect salty, crunchy topper for guacamole.
