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. 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...

How Defining Moderation Can Help You Reach Your Health Goals

We’ve heard it a million times: “Eat a well-balanced diet with everything in moderation.” After all these decades of clear failure, it’s a hazy cliché still delivered by physicians, dietitians and nutritional “experts” with earnest assurance. The same goes for exercise and stress. Moderate amounts of stress are okay, moderate cardiovascular work is good, etc. We accept the concept of moderation so readily, I think, because it sounds so rational and simple. If we follow common sense, moderation suggests, we’ll be fine. But if it were that easy, most people would be healthy—and statistics on the rising rates of obesity and chronic illness tell us otherwise. So what’s the problem?

Dear Mark: Bikram Yoga; Stored Toxins Impairing Fat Loss

For today’s edition of Dear Mark, I’m answer two questions from readers. First, does Bikram yoga qualify as sprinting or high intensity training? It’s certainly intense, and it’ll make you sweat bullets and work hard to the point of nausea, but does it actually accomplish the same training effects as sprinting or intervals? Find out down below. Next, you often hear that body fat is the main repository for environmental toxins. This is true, but does that mean the body “holds on” to body fat to prevent systemic dispersal of the toxins it contains? Can stored toxins make losing body fat harder that it already is?

Why the Kind of Body Fat You Carry Matters

All fats are not created equal. We know this because we’re constantly correcting people who get it wrong. There are good fats and bad fats and really really bad fats and fats that are conditionally good or bad. Butter isn’t corn oil isn’t fish oil isn’t monounsaturated fat isn’t palmitoleic fat isn’t linoleic acid. Sometimes trans fat isn’t even trans fat. The same thing applies to the fat on your body. Depending on its location and composition, healthfulness isn’t distributed equally among adipose tissue. Some types of body fat are worse than others.

Fat is an endocrine organ. Like any other organ, it secretes hormones and other bioactive compounds that affect our physiology and determine our health.

8 Essential Tips for Primal Men

Men I know. I am one, after all. Have been for many years. For the most part, I enjoy it. It’s worked out really well for me. I don’t find it particularly difficult to be a man. Once I dialed in the basics of this Primal stuff, my health improved and my fitness became more well-rounded and applicable to the things I enjoyed doing. I haven’t struggled much. But many people do. And while the majority of Primal advice is geared toward humans in general, I’ll just get this out of the way early: These “men’s tips” all apply to many women, too. And many of the “women’s tips” from last week’s post also apply to men. But ignoring the gender-specificity of general trends serves no one. Everyone has the capacity for competitiveness; men tend to have more. Both genders can benefit from fasting, but women are more likely to have negative responses. Men and women both need sleep; lack of it hits women harder. That’s all. As always, if you recognize yourself in these tips, go for it!

12 Essential Tips for Primal Women

Look: I’m a man. I’ve lived a different experience than the average woman, with totally different equipment and different concentrations of hormones coursing through my body. But I have a daughter and a wife and a good head on my shoulders that’s spent the last 30 years thinking about health, nutrition, and fitness for humans, so I have a few things to offer.

So let’s get right down to today’s post. What follows are 12 tips for Primal women. Or any woman, really.

(Men, too: if some of the things mentioned in today’s post aren’t working for you, and the tips seem to apply, go for it!)

Dear Mark: Higher BMI and Mortality Risk, Calories When Meal-Skipping, HIIT After Fasting

For today’s edition of Dear Mark, I’m answering a couple questions from you guys. First, there’s a new paper out claiming that the ideal BMI for overall mortality is an overweight one—27, to be exact. Is this really the case? Should we all pack on a few extra pounds to see us through into old age? Next, should you try to make up for all the “lost” calories when you eat in a compressed eating window? If you skip breakfast, should you try to eat more at lunch? And finally, how does one incorporate high intensity interval training on a low-carb diet that includes fasting?
