The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate...
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
It’s Friday, everyone! And that means another Primal Blueprint Real Life Story from a Mark’s Daily Apple reader. If you have your own success story and would like to share it with me and the Mark’s Daily Apple community please contact me here. I’ll continue to publish these each Friday as long as they keep coming in. Thank you for reading!
Last September marked the one year anniversary of the beginning of my Primal Journey. It’s been a life changing year for me and my family. I finally feel ready to tell my story. So here we go…
I can honestly, whole-heartedly say that my whole life, I felt like I was way off course. I am smart, athletic, was always successful in school, came from a good family, knew my career choice (teacher) at a young age and was passionate about everything I did. Despite my “normal” life, I struggled deeply with anxiety as long as I can remember. I never felt normal, or like I could handle anything. The slightest bit of stress sent me into a life or death reaction. I honestly thought I was crazy, but I knew deep down that this wasn’t how I was supposed to be living my life. This wasn’t ok. I knew that for sure.
This may seem like a redundant topic, since most of you following a Primal eating plan are already avoiding wheat. The occasional dabbing of soy sauce, maybe a bit of crusty bread at a restaurant, sure, but for the most part, you’re not munching on baguettes in parks on sunny days, wolfing down huge sandwiches, and eating pasta. Wheat avoidance tends to be the rule in our circle. Still, though, haven’t you had that moment where someone asks “What’s wrong with wheat?” and you mutter something about gluten and the advent of agriculture that doesn’t really sound convincing, even to you? Consider today’s post a crash course in exactly why modern wheat in particular is a problem. To borrow a horrible concept that has helped politicians and their cronies obfuscate the truth for decades, these are “talking points” to which you can always refer when asked. The only difference is that these talking points are based on actual research.
A new study came out last month out of France. In it, researchers found that rats on diets consisting of 11%, 22%, and 33% Roundup-resistant genetically modified corn developed far more mammary tumors than control rats on non-GMO corn diets. GMO diet rats died earlier and in greater numbers. Why is this study notable amidst all the other studies that seem to show the safety of GMOs? Well, it’s one of the few long term GMO feeding studies, lasting a full two years, which, to a rat, is the equivalent of 60 of our human years. The other safety studies which found no evidence of toxicity in GM foods tend to last just 90 days, or 15 rat years. In other words, the French study studied rats over the course of an entire lifespan, whereas other studies have looked at rats for a relatively brief snippet of their lives. Cancer generally develops over a lifetime, as you probably know, so this would appear to be more relevant to human health than the shorter trials.
At first glance, these may seem inconsequential to the casual reader. Biodiversity? That sounds like some fancy newspeak conjured up by Greenpeace! Soil health? How can soil be healthy? It’s just a collection of inanimate bits of dirt and clay and sand! Bee health? What do I care about a lousy bee? All those things have ever done is sting me, vomit up fructose, and make annoying buzzing noises. Carbon sequestration? Carbon dioxide is a mythological compound! It doesn’t even exist. Worker health? I dunno about you, but it looks like they’re getting a great workout to me, and what’s healthier than that?
Although I’m exaggerating these reactions, of course, the fact is that a lot of the potential benefits of organic farming are lost on consumers because they fail to immediately impact your health in the here and the now. You might be vaguely aware that biodiversity, the health of the soil, the role of bees, the ability of soil to sequester carbon, and the health effects of conventional farming on farm workers are “important” to consider, but are they important enough to nudge you toward consuming organic?
Last week, I made the suggestion that people interested in maintaining health and immunity while avoiding excessive oxidative stress should expend no more than 4,000 calories per week through focused exercise, a recommendation that I’ve found to be pretty sound for most of the general population. You guys had plenty of questions about that recommendation, as I expected, so today I’m going to devote the entirety of “Dear Mark” to answering some of those questions. I didn’t get to all of them, but I did try to tackle a representative swath. Don’t expect big sprawling walls of text; I’m just doing this rapid fire style. If I’ve made any glaring omissions, let me know and I’ll see if I can answer them at a later date.
That said, let’s get right into it:
“Uninterrupted bouts of sedentary behavior” are strongly associated with lower insulin sensitivity, impaired glucose tolerance, and increased triglyceride levels, according to a new review. Of course, most of the available research was performed on males, not females, and all you’d need to do to mitigate any potential damage is interrupt your sedentary bouts with movement.
Here’s one quick (but grueling) way to interrupt those bouts of sedentism: five all-out 30 second sprints separated by four minute rest periods.
