Meet Mark

Does Diet Influence Menopause Timing?

Last week, I linked to a story about a popular vegan blogger, author, and influencer who found herself going into menopause at the age of 37 despite doing “everything right.” She exercised, she ate raw, she avoided gluten and refined sugar, and, most importantly, she avoided all animal products. Now, this wasn’t a randomized controlled trial. This wasn’t even a case study. But it was a powerful anecdote from someone whose livelihood depended on her remaining a raw vegan. It wasn’t in her interest to make it up.

So, it got me wondering: How do diet and lifestyle influence the timing of menopause?

Definitive Guide To Sprinting, Part 1: Benefits of Sprinting

As Primal enthusiasts know, sprinting is an essential element to leading an optimally fit life. After all, it’s one of the 10 Primal Blueprint Laws, and perhaps the quintessential anti-aging activity. Brief, explosive all-out sprints are the single best activity to promote rapid reduction of excess body fat, achieve fitness breakthroughs, flood the bloodstream with anti-aging hormones like testosterone and human growth hormone, and boost neuron function in the brain. Even a very brief sprint session has a profound effect on your metabolic and hormonal function for hours and days afterward, sending what Paleo movement pioneer Dr. Art DeVany calls a “renewal signal” to your genes.

Archetypal Resting Positions: How Sitting Like Your Ancestors Could Save Your Health

Tennis elbow, Achilles tendinitis, osteoarthritis, and other connective tissue injuries are on the rise. Athletes have always gotten them, but it’s only in the past few decades that regular folks are getting them too. For some connective tissue injuries, non-athletes outnumber athletes. That shouldn’t happen if the conventional wisdom—injuries to tendons, ligaments, and cartilage occur only because of overuse or overloading during intense physical activity—were true.

Now, of course the way we train affects the health and function of our connective tissue. Acute injuries absolutely occur. Overuse injuries absolutely develop. But that’s to be expected. Athletes put their bodies through a lot, and there is going to be fallout from that. Where those injuries shouldn’t be happening is in regular, everyday folks who don’t train for a living or engage in intense physical competition on a regular basis. And yet that’s exactly how it’s going down in the world today. In one recent study, the majority of patients with Achilles tendon injuries couldn’t attribute their condition to working out or playing sports. In other words, they just got it.

CBD For Performance: What We Know So Far

I left the pro athlete world a long time ago. I no longer compete. I don’t train with the intensity and volume it’d take to win races. But I do pay attention to what’s going on in that world, and I still have a lot of friends who never left it. Developments there often foreshadow developments in the rest of the health world. And after things like keto, MCT oil/ketones, and collagen, the performance hack that’s blowing up among elite athletes is CBD oil. Almost everyone I talk to who puts in serious training and competing time (in a variety of sports and pursuits) is dabbling with CBD.

What are they using it for?

Dear Mark: Antibiotic Recovery, Sprinting on Keto, Preparing for Bad Sleep

For today’s edition of Dear Mark, I’m answering three questions. First up, what can a person do to help their gut recover its barrier function after too many antibiotics? Are there any foods, supplements, or dietary strategies? Second, what can explain rapid fatigue during sprint sessions on a keto diet? Is this simply part of the deal, or are there modifications you can make? And finally, what do I do when I know I’m going to get a bad night’s sleep?
