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...

Should You Chew Your Child’s Food?

By now, you’ve probably seen the Alicia Silverstone pre-mastication video. It’s totally safe for work (maybe not for lunch, but your mileage may vary), but some viewers will find it a bit unsettling: Silverstone feeds her baby pre-chewed food directly from her mouth, just like a bird. I found it pretty fascinating and not at all upsetting. Before you recoil in disgust and/or horror, think about how people weaned babies before Magic Bullets, Vitamixes, Gerber baby food, and even mortar and pestles hit the scene. That’s right – they chewed their food for them. In a paper entitled “Premastication: the second arm of infant and young child feeding for health and survival,” Gretel Pelto speculates that pre-mastication was likely common practice among pre-agricultural groups and confirms that it continues today across every continent (PDF).

Why Fast? Part Six – Choosing a Method

Assuming you’ve been keeping up with the series, you should be saying to yourself “Hey, maybe this fasting thing would be a cool thing to try out, and it might even make me healthier/live longer/lean out/lose weight/etc.,” which is a sufficiently extensive list of benefits, don’t you think? I could probably go on theorizing and speculating about all the reasons why you should consider intermittent fasting, but I’d rather move on to the implementation. Thinking about fasting, reading about fasting, and reciting the benefits of fasting are all pointless if you don’t know how to go about doing it.

First, let’s go over the different variations of fasting. I’ll give a quick rundown. Each involves not eating for a period of time, unsurprisingly.

A couple other rules that apply to all the given methods:

Dear Mark: Vegetarian-Fed, BCAAs, and Bland Grass-Fed Beef

You’re at the store, and you want to get some beef. You’ve been keeping up with the word on the street, so you’re aware of the importance of the cow’s diet. You look around for grass-fed beef, but have zero success. They do, however, have “vegetarian-fed” beef, which sounds nice. I mean, who wants their beef eating animal parts? And aren’t vegetarians pretty healthy? Why, I bet vegetarian-fed cows are even healthier! Eh, not so fast. What does it really mean? Anything? Labels can be tricky. Usually are, in fact, by design. And sneakiness works.

So – do these labels actually tell us anything we didn’t already know? Let’s find out the answer to this and other reader questions.

Blogging from PrimalCon 2012 – Day 3

I’ve spent the whole weekend trying to wrangle a 9 1/2 week old puppy that I’ve only had for four days while interacting enough to cobble together a a few blogs that somewhat encapsulated the PrimalCon 2012 experience, and I think I did a fair job. I’m dead tired. Too tired to join an epic 2-game Ultimate Frisbee series spanning an hour and a half. (Mark’s team lost the final match by a couple points, and, contrary to his claims of it being merely his outlet for carefree whimsical play, he takes it pretty seriously.) But despite all that, I feel good. It feels good to help put something like PrimalCon together, something that people really seem to appreciate. Because I work in this world, and almost everyone around me is clued in, it’s easy for me to forget that most people who get into this Primal stuff often do so as lone wolves without a Primal pack. So it’s been fun to see people discovering their pack.

Blogging From PrimalCon 2012 – Day 2

Day 2 of PrimalCon 2012 is done, and it was possibly the best yet.

It wasn’t the fact that the sun came out and the clouds went away and we spent the day outdoors. And it wasn’t just because they doubled the burger portions for lunch and served Asian-cut short ribs, three kinds of salad, and beets for dinner that made it so awesome. Nor was it the several dozen bottles of red wine served with dinner. All that stuff was incredible and definitely contributed, but the real reason today rocked most was that the structure of the day and its content was free and open-ended. Rather than have more formal lectures by top experts where attendees consumed information and insight, day 2 was about attendees engaging other attendees and the experts on their own terms.

Blogging from PrimalCon 2012 – Day 1

Today was crazy. Immediately after the welcome speech by Mark and Brad, and all the introductions, which went very smoothly, things started to change.

Although “choices” was the theme of Mark’s keynote talk this year, the weather gave us very few. It was cold, windy, rainy, and thundery (sure, that’s a word); we had planned for warm, still, dry, and silent. It started during the first (and last) presenter session of the day held outdoors. Just as Erwan was showing folks how to skillfully and smoothly swing themselves up on top of playground sets, big broad Star Wars blaster bolt-like sheets of water (but with better accuracy than the stormtroopers) starting coming in at a 45-degree angle, practically sideways. Everyone got soaked, had to come back to the Embassy Suites ballroom, and our initial plans to dine at Oxnard Beach Park, outdoors, got scrapped.
