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...

3 Common Types of Headache (and How to Treat Them Naturally)

One major downside to having these big prominent heads stuffed with consciousness-spawning brain matter is that they sometimes ache. Nobody likes a headache. You can find fetishists who enjoy pinching, slapping, biting, burning and any matter of objectively painful stimuli. But there aren’t “headache fetishists.” No one’s chugging a 32 ounce Slurpee in search of brain freeze, or getting drunk for the hangover.

The difficult thing about headaches is figuring out why they’re occurring. Pain in other areas is different. You can look at your hand if it’s hurting and figure out why. You can see the cut on your knee and know what’s going on. But you are your head, and the headache is inside. Your consciousness sits behind your eyes observing reality and directing your role in it. It’s all a big mystery. Or so it feels.

Dear Mark: Amino Acid Supplements, Preventing an Infection, and Knee Pain in a Lunging Athlete

For today’s edition of Dear Mark, I’m answering three questions. First, are the amino acid supplements sarcosine, D-serine, and D-cycloserine worth taking? What do they do and who can they help? Next, what should you do to prevent an infection? Besides the regular stuff like vitamin C and vitamin D, is there anything else to take to mitigate the damage and prevent pathogenic incursions? And finally, I field a question from a fencer and martial artist who’s feeling the beginning twinges of knee pain. He leads a lunge-heavy life—it’s an inescapable part of his training—and I offer a few suggestions for limiting the damage.

Let’s go:

8 Essential Tips for Primal Men

Men I know. I am one, after all. Have been for many years. For the most part, I enjoy it. It’s worked out really well for me. I don’t find it particularly difficult to be a man. Once I dialed in the basics of this Primal stuff, my health improved and my fitness became more well-rounded and applicable to the things I enjoyed doing. I haven’t struggled much. But many people do. And while the majority of Primal advice is geared toward humans in general, I’ll just get this out of the way early: These “men’s tips” all apply to many women, too. And many of the “women’s tips” from last week’s post also apply to men. But ignoring the gender-specificity of general trends serves no one. Everyone has the capacity for competitiveness; men tend to have more. Both genders can benefit from fasting, but women are more likely to have negative responses. Men and women both need sleep; lack of it hits women harder. That’s all. As always, if you recognize yourself in these tips, go for it!

12 Essential Tips for Primal Women

Look: I’m a man. I’ve lived a different experience than the average woman, with totally different equipment and different concentrations of hormones coursing through my body. But I have a daughter and a wife and a good head on my shoulders that’s spent the last 30 years thinking about health, nutrition, and fitness for humans, so I have a few things to offer.

So let’s get right down to today’s post. What follows are 12 tips for Primal women. Or any woman, really.

(Men, too: if some of the things mentioned in today’s post aren’t working for you, and the tips seem to apply, go for it!)

8 Ayurvedic Herbs That Actually Work

With so many time-tested treatment modalities out there, some which are thousands of years old, people are pretty curious as to whether some of the natural tips and recommendations penned in ancient literature are still effective today. Conventional medical wisdom assumes all that ancient medicine is just nonsense and superstition, that until a hundred years ago every health practitioner and patient lived under a massive collective delusion. If they got anything right it was through dumb luck, and today’s pharmaceutical companies have long since mined it for useful drugs and therapies. Could they all be useless? Whereas some older treatments have gone the way of the dodo in light of scientific scrutiny, many endure. In today’s post, I’ll subject the ancient world of Ayurvedic herbs to that same scientific scrutiny.

Dear Mark: Vegetarianism Causes Cancer?; Glucosamine Useless?; Decision Fatigue Debunked?

For today’s edition of Dear Mark, I’m answer three questions. First, does long-term vegetarianism cause cancer or alter our genetic code? Some media coverage of the latest vegetarianism study seemed to suggest as much. Next, is glucosamine just totally useless if you’re not going to fork out a ton of money for pharmaceutical grade stuff? Maybe not, but let’s find out. And finally, I’ve written about decision fatigue a couple times before. What’s my take on the new research seeming to debunk one of the central concepts supporting it—ego depletion/finite willpower?
