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...

Is Keto for Everyone?—Cautions, Caveats, and Contraindications

In a few months, I’ll be releasing a book extolling the virtues of a ketogenic diet. I’m currently several months into a ketogenic experiment, which is going well. I just wrote a Definitive Guide explaining why you should consider going keto. I’m on record as stating that everyone should dip into ketosis from time to time. You’d think I’d recommend that everyone go keto. Right?

There are caveats. There are contraindications. There are very good reasons for a person not to go keto, or at least to take a few extra precautions. Today, I’m going to tell you when you should exercise particular care when considering a ketogenic diet.

Dear Mark: Keto Follow-Up

For today’s edition of Dear Mark, I’m answering some questions from the comment board of last week’s Definitive Guide to Keto. You folks came up with some great ones. Is counting carbs in non-starchy vegetables still unnecessary on a ketogenic diet? What’s the connection between ketosis and “starvation mode,” and should we be worried? What if you don’t want to lose weight on a ketogenic diet—what modifications should you make? Are you in danger of blowing a breathalyzer test due to ketone metabolites on your breath? Can endurance athletes benefit from keto? Is cyclical ketosis preferable to constant ketosis? Are sugar alcohols ketogenic-friendly?

ACEs and Primal Health

It’s fair to say that I gravitate towards tangible, actionable subject matter when it comes to improving my own and others’ health. Things like nutrition, fitness, sleep, hormonal responses, and supplement science may seem like a lot to chew on for the layperson, but these are my personal passions as well as my long-time profession.

And while these are certainly the big, actionable players in the game of health, I fully acknowledge there may be more lurking behind the scenes than we realize. A body that refuses to heal no matter how Primal you eat. Stubborn health conditions that simply refuse to fully go away, despite all the changes you make in your life. A propensity for disease that defies everything you’ve learned about ancestral nutrition and wellness. An intriguing new angle in the health sphere suggests the hurdle for some people may be embedded deeper than outer changes can access.

Dear Mark: Too Much Serotonin and Broccoli Sprouts

For today’s edition of Dear Mark, I’m answering two questions from readers. The first is more of a comment, but it brought up a few questions for me to address. Is “more serotonin” always a good thing? Is there such a thing as too much serotonin? And second, what’s the deal with broccoli sprouts? Are they good for us? Has the grungy hippy hawking sprouts next to your meat guy at the farmers market been right all along?

7 Alternative Therapies for Depression

As I discussed last month, depression is the yin to anxiety’s yang. Between these two troublemakers, they’ve got dark clouds hanging over both the past and the future, making the present moment complicated at best (and for some people unbearable). Taken as a human composite, it’s an unfortunate trade-off for being cognitively complex. As individuals, however, we naturally just want a solution.

The problem is, there’s just so many confounding factors surrounding depression that it’s hard to know where to start. Your mind is an infinitely complex latticework of moving parts; one which continues to baffle and divide the scientific community. How does a practitioner prescribe suitable treatments for a problem they don’t fully comprehend? And, yet, medical science often (and perhaps inevitably) works with incomplete information.

Summer Reset: 30 Days, 30 Actions (Plus a 21-Day Staff Challenge AND Giveaway!)

At the onset of our annual 21-Day Challenge this past January, I offered up a post that proposed thinking small—“41 Primal Action Items and Individual Experiments for Success in 2017.” The idea here wasn’t shrinking our scope to the exclusion of big visioning, but homing in on the day to day aims we can set for ourselves that make the big changes happen.

I think June is a good time to revisit that premise—and to host another 21-Day experience for those more inspired in the summer months.
