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’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?

Last week, you guys asked me a ton of questions as part of a contest. Today, I’m going to answer an initial batch. (If you don’t see yours, check back on Mondays to come when I’ll take up others.)

Primal Transition 101: Insider Kitchen Tips

Transitioning to the Primal Blueprint way of eating should be simple. There’s no need to invent the wheel at every meal. That said, it does likely mean shifting some of your routine in the kitchen. If you’re used to processed food, enjoy getting your hands a little messier. If you’re used to take-out, capitalize on the chance to use your creative skills. (Don’t worry, you’ve got an abundance of recipes and cookbooks right at your fingertips.) That said, all Primal cooks—beginners to old-timers—can make life easier with a few select tactics.

For today’s edition of Dear Mark, I’m answering three questions from readers. First up, what’s the best way to increase your HDL particle count? There are dozens of articles explaining how to reduce LDL-P, but what about HDL-P? Second, are ketones right—or necessary—for everyone? The final question comes from a reader who, despite sticking with the diet for four months, hasn’t felt the fabled “keto energy.” Should she try ketone supplements, give it more time, or what?
