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.

Dear Mark: Vegetable Powders, Pro/Prebiotic Timing, RS Questions, and Routine Eating

For today’s edition of Dear Mark, we’ve got four questions and four answers. First, I explain the merits and drawbacks of vegetable powders in the event of low produce availability. Next, I discuss whether there’s a perfect time to take your probiotics and prebiotics, or whether it doesn’t matter at all. After that, I answer a quick barrage of resistant starch-related questions, followed by a query regarding a monotonous eating regimen that by all accounts appears to be working very well. Is there a hidden danger in eating similar meals all the time?

How to Conduct a Self Experiment: Resistant Starch

It’s been well over a year since we last did a self experimentation post, and I think it’s time for one on that current sensation: resistant starch. Whether you’re an ardent low-carber, a carnivore, or a safe starch fanatic with dried up rice stuck to your lapel, the allure of improved sleep, better glucose tolerance, lower blood sugar, and solid digestion is universal. I mean, sure, there are probably some fetishists who prefer difficult toilet experiences and creative types who thrive on the weird headspace created by sleep deprivation, but the effects often attributed to resistant starch consumption are objectively beneficial.

Resistant Starch: Your Questions Answered

Last week’s Definitive Guide to Resistant Starch garnered a lot of attention. While the article covered a lot of ground, many of you had lingering questions and concerns about the topic: What is and isn’t resistant starch? How much resistant starch should I be eating? Why is resistant starch good for me? What is resistant starch again?

I don’t blame you; it’s a confusing one that appears, on first glance, to challenge some of the fundamental Primal ideas about food and nutrition.

Today, I’m going to answer as many questions from last week as I can. Hopefully it clears up most of the bigger questions.

Let’s get right to it:

The Definitive Guide to Resistant Starch

A few years back, I briefly covered a throwaway Yahoo! article about how “carbs will make you lose weight” because so many readers had emailed about it. It turned out that the “carbs” in the article were resistant starch, a type of carbohydrate that our digestive enzymes cannot break down. I’ll admit now, with regret, that I didn’t look as deeply into the matter as I might have. I didn’t dismiss resistant starch, but I did downplay its importance, characterizing it as “just another type of prebiotic” – important but not necessary so long as you were eating other fermentable fibers. While technically true, we’re fast learning that resistant starch may be a special type of prebiotic with a special place in the human diet.

Dear Mark: Sprints and Blood Sugar, Resistant Starch as Carbs, PUFA in Coconut Oil, Cycling as Chronic Cardio, and Morning Sickness

For today’s edition of Dear Mark, I cover four questions and my wife Carrie covers one. First, I discuss the effects of sprinting on blood sugar in the short term and long term. Next is whether or not one counts resistant starch as a carb in their daily allotment. Third, I identify the actual proportion of omega-6 polyunsaturated fatty acids found in coconut oil. Finally, I give my take on cycling as a gentler mode of chronic cardio relative to running. Carrie wraps things up with a short review of the evolutionary reasons for morning sickness.

Dear Mark: Resistant Starch, Zinc Deficiency, and Something New

For today’s edition of Dear Mark, we’ve got a three-parter. In the first section, I discuss the extremely hot (and then allowed to cool off) topic of resistant starch, explaining who might benefit from it, who might not, and where you can find further information on the subject. Second, I briefly go over how a zinc deficiency might arise and how you can address it on a Primal eating plan. The third section is bit of a surprise, featuring a very special guest writer. Since this is text and you guys can just skip ahead to see who it is, there’s admittedly very little suspense. But still. It’s a surprise that I think you’ll enjoy and appreciate.
