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...

A Primal Look at Gestational Diabetes

Every pregnant woman I’ve ever known has hated the oral glucose tolerance test. Yet, they still do it. Drinking a tall glass of sickly sweet orange-flavored glucose water on an empty stomach is thoroughly disgusting, but it, apparently, offers a rare and valuable glimpse into the state of a woman’s perinatal health.

What they’re testing for is gestational diabetes mellitus—a variant of diabetes characterized by pancreatic insufficiency during pregnancy.

Dear Mark: Hydroponic vs. Regular Vegetables; Lowering Blood Pressure Without Meds

For today’s edition of Dear Mark, I’m answering two questions. First up, do the nutrient contents of hydroponic produce differ from soil-grown produce? If so, in what way? Then I give a few (somehwat unprompted) tips for lowering blood pressure without meds. While meds can and do help people overcome or mitigate hypertension, we should apply other options. What are these possibilities?

Dear Mark: Steak Satiety vs Ground Beef Satiety; Maca and Cacao During Fasts; Nut Butters, and Post-work Workouts

For today’s edition of Dear Mark, I’m answering four questions from readers. First, why might a pound of ground beef induce less satiation than a pound of steak? Second, can you take maca root and cacao powder during a fast without breaking it? Third, what’s my take on nut butters? Good kitchen allies or too much of a good thing—or both? And finally, I give a few tips for someone who wants to train more regularly but can’t find the energy required after work.

What’s Wrong with the “Best Diets”?

Every year, it’s the same thing: U.S. News and World Report ranks 38 of the most popular diets from best to worst. And every single time, the paleo diet—or some variant, in this case the Whole30 plan—comes in dead last. I’ve written about this before. You know my stance. You know how silly the whole thing is, and why you shouldn’t care about a ranking, especially when you’ve transformed your health eating the “worst diet in the world.”

Frankly, I’m skeptical these reports have much impact anymore.

Where Do I Start? The Big Picture on Tackling Primal Challenges

Earlier this month, a reader posed a fantastic question that prompted today’s post. It was long, so I’ll give the choice bits rather than quote the entire thing:

Where do I start? I’d be interested in seeing your opinion on the relative impact of various primal lifestyle changes… Eating “clean” would be a 10, etc… but what about subtler things like sprinting, IF, quality sleep, sunlight, and play… So I guess I’m asking you to write on a 30,000ft level, how all these things interplay and what their relative contributions are to overall wellness.

Where does one start indeed?
