Meet Mark

The Keto Carb Threshold: What Constitutes a “Keto” Meal?

How many carbs can you eat in a sitting and still “stay keto”? What constitutes a “keto meal”?

I’ve gotten many questions about this topic.

First of all, let’s get this out of the way: Keto is not a religion that punishes heretics with eternal damnation (or eternal reliance on exogenous sugar for energy). This post is not intended to make people feel guilty for eating five grams of carbs over the” limit.” It’s not even intended to set a hard limit in stone. It’s simply to provide people who care about this sort of thing a basic, admittedly rough, guideline for staying below the keto carb threshold within meals throughout the day.

Keto Convenience Foods: What To Try (and What To Skip)

If you read any of those “10 Reasons Keto is the Worst” articles out there, the common anti-keto argument you’ll see is that it’s too hard. The premise: keto must be unsustainable because eating meat, eggs, avocados, veggies, nuts, coconut, etc. is just too arduous long term. I’m sure you can guess how I feel about that.

Nonetheless, when you switch from a SAD diet to Primal or Primal-keto it genuinely becomes harder to grab convenience foods. It’s not that you can’t. The selection of packaged foods being marketed to keto folks has exploded in the past year or so. Rather, your growing awareness of ingredient quality, coupled with a desire to control your food and nutrition, makes it feel harder… and probably less desirable.

Dear Mark: CBD Edition

For today’s edition of Dear Mark, I’ll be answering your CBD questions from the past few weeks. CBD, or cannabidiol, is exploding in popularity, but there are many unknowns. People have a lot of questions and there aren’t many definitive or comprehensive guides, so today I’ll do my best to make sense of it. We’re all piecing things together based on limited data—which, I suppose, is the fundamental human experience.

Let’s go:

Is Keto Cheating Unhealthy?

A couple months ago, a study came out that seemed to show that cheating on your keto diet with a high-carb meal opened you up to severe blood vessel damage. Nine healthy, normal weight adults followed a keto diet (70% fat, 20% protein, 10% carbs). Then they ate a high-carb “cheat meal,” measured their blood sugar, and measured their endothelial microparticles—a marker of damage to the endothelial lining and potential harbinger of impaired vascular function. Their blood sugar went way up, and so did their endothelial microparticle count, leading researchers to conclude that keto dieting makes people more susceptible to hyperglycemia-induced endothelial damage.

So, is keto cheating unhealthy? Let’s take a closer look….

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?
