The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate in...
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...Tell Me More
The explosive growth of interest in the ketogenic diet has been a net good for the state of nutrition. For one, people have accepted the fact that eating fat won’t kill you, and they’re even getting clued into the benefits of eating it.
But there are places where I part ways with the popular keto movement.
Let me explain….Read More
After I turned 60, a routine checkup showed that I had lower-than-normal free testosterone levels. I hadn’t noticed anything that would have alerted me. No symptoms. No indication. Everything worked well. But it nagged at me. I knew testosterone did much more for a man’s health than just “build muscle”—which I had no real interest in at this point—so I decided to explore TRT, or testosterone replacement therapy.
I did a careful survey of the literature, coming away pleasantly surprised. The evidence was almost uniformly in favor, with the well-constructed studies showing major benefits for TRT. This is TRT, mind you. Not “juicing,” not steroid abuse. Restoration of biologically-appropriate levels of testosterone. Thus began my experiment….Read More
I’ve taken up the subject of adaptogens over the last several weeks, and today I’m wrapping it up with two of my favorites: Rhodiola rosea and Bacopa monnieri.
Primal aficionados from way back will know that I’m a big fan of Rhodiola rosea. It’s an integral component of one of the original Primal Blueprint supplements, Primal Calm. It’s a formula I put together for my own needs and eventually decided to offer in the supplement line. (That seems to be how I come up with things, I suppose….) I’ve written in the past about stress being one of the issues I’m still working on in my Primal life, and adaptogens have been a useful tool I’ve employed. Living with an ancestral template doesn’t preclude being scientifically resourceful.
But let’s dig into these final two players….
My friend, former co-competitor, business partner, and writing buddy Brad Kearns had been on a “Quantified Self” kick, tracking biomarkers, testing blood sugar and ketone levels, and staying abreast of all the various ways we can quantitatively check our progress. He’s months into a ketogenic experiment and had hoped to marry his subjective impressions to objective measurements to strengthen his intuition and improve his results.Read More
For today’s edition of Dear Mark, I’m answering a couple questions from readers. First, is nature always relaxing and blissful? Or are there instances where being in nature is far more stressful than being indoors? Why, and what should we do about it? Second, how do I use fish sauce, and how would a parent use fish sauce to get picky kids to try (and like) new foods?
Let’s go:Read More
Last week I waded into the adaptogen theme, examining the many ins and not-so-many outs of American and Asian ginseng. It got me thinking—why not keep the ball rolling? The ginseng varieties I mentioned are only two among many adaptogens after all.
Let’s dive right in and take up three additional adaptogen choices—along with some additional suggestions for discerning the safest and most potent formulations.
