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...

10 Tips to Boost Your Serotonin

Serotonin is a major regulator of mood and depression risk. These are important, vital roles, to be sure. Your mood describes how you experience and interpret the world. If it’s consistently bad, you’regoing to have a rough time. Yet, serotonin is much more than the “feel-good hormone.” It also influences sexual desire and helps us remember. It’s the precursor to melatonin, the neurotransmitter that allows us to sleep.

Anxiety: Are Nutritional Deficiencies a Common Cause?

As big-brained hominids, humans have the unique ability to think about the future. The very fact that we can perceive and plan for the time ahead has allowed us to conquer the earth, but it comes with a downside: anxiety. If extreme rumination on past events characterizes depression, worrying about imagined future scenarios describes anxiety.

This inherent capacity and human tendency to think ahead must be reined in and controlled. One way we can do that is make sure we’re getting enough of the nutrients that studies indicate may play an etiological role in anxiety.

5 Obscure Nutrients: Why We Need Them and How Grok Got Them

Everyone reading this knows about the macronutrients. You’re all eating enough protein, fat, carbs, and the various sub-categories, like fiber, omega-3s, MUFAs, SFAs, linoleic acid, and so on. You know the major micronutrients, like magnesium, calcium, vitamin B12, and most of the minor (but still vital) ones, like plant polyphenols, iodine, and vitamin K2. Today I’ll be talking about the truly obscure nutrients. The ones health food hipsters were super into like, five years ago (“I’m taking beta-1,3-glucan, you probably haven’t heard of it, there’s only one group at Hokkaido University doing any research, you can only get it off the DarkNet using bitcoins”). The ones Grok was super into like, 50,000 years ago.

What are they, what do they do for us, and, if they’re so great, how did Grok obtain them?

How to Buy (and Appreciate) Eggs

Time and again I find myself on the topic of eggs. I’m a fan really. In fact, I had them for breakfast just this morning (as most mornings).

They’re one of nature’s true superfoods after all—pre-packaged and ready to enjoy however you see fit. The healthy fats, proteins, vitamins and minerals contained within simply can’t be ignored, regardless of all those misguided cholesterol-haters out there.

Back in 2008, I provided a brief look into deconstructing egg carton labelling. That simple guide to egg purchasing has gotten a fair amount of attention and shares over the years, so I’m revisiting the subject to update and elaborate where it makes sense. I don’t see eggs ever losing their place in paleo/Primal eating, and I know others share my enthusiasm.

Dear Mark: Your Challenge Questions Answered

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.) First, can excess fat be stored as body fat? If so, how? Second, can this way of eating help with seasonal allergies? Third, what’s the proper pushup progression for someone who can’t do a full one? Fourth, when should I take my probiotics, vitamin D3, and fish oil? Fifth, is canned fish a viable way of obtaining omega-3s, or does the canning process damage the fats? Sixth, is there a trick to beating a weight loss plateau? Seventh, is there a way to make sardines palatable? And eighth, if you can’t walk one day, can you make it up the next?

Let’s go:

The Benefits of Caloric Efficiency (and 10 Ways to Achieve It)

We really like to eat. We choose restaurants based on portion size. We work out just to increase our capacity for guilt-free gluttony. And even when we don’t actually like it, we still want it because the food industry employs experts in brain hedonic processing to engineer food products your brain literally cannot stop craving. As Louis CK put it, we don’t stop eating when we’re full, we stop eating when we hate ourselves.

I’m not immune. In college, they called me Arnold, after the pig from Green Acres, because I could (and did) out-eat anyone. Linebackers 1.5x my size were no match. I love food, but I’m not interested in cramming as much food as I can get away with. Not anymore.
