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...

Dear Mark: Unraveling a Stress Ball, Fiber for Plant-Hating Tot, Offal with Grains, and Exercising with a Cold

For today’s Dear Mark, we’ve got a four-parter. First up is one from a woman in her mid-30s trying to recover from a three-year bout of chronic stress — and all the metabolic fallout that entails. Are there any supplements to help with her situation? Second, what do you feed a picky kid who hates vegetables, hates fruit with peels, and needs more prebiotic fiber? I give a quick list of ideas for getting things moving again. Third, are traditional foods like haggis and liver pâté worth eating if they contain non-Primal ingredients you’d usually avoid? Are the nutrients found in offal really that important? And finally, I help a reader figure out whether she should be exercising while sick.

Let’s go:

Are Video Games Good or Bad for Us?

Non-gamers tend to take a dim view of video games and their fans, assuming they’re all a bunch of sweaty man-children clutching liter bottles of Mountain Dew between Cheeto-dusted fingers and screaming racist obscenities that diffuse, muffled, through thick neckbeard thatches into their headsets at online opponents. And a few weeks ago, even I referenced the stereotypical World of Warcraft addict’s set-up of pee bottles and poop buckets. But the latest statistics indicate that the popular stereotype isn’t very representative of most gamers. In fact, if you’re an American, you’re more likely to be a gamer than not:

How to Increase Your Heart Rate Variability

Last week, I introduced the concept of heart rate variability – the variation of heart beat to beat intervals. Far from the metronome we might assume it to be, the healthiest heart beat follows a fractal pattern, with varying lengths of time separating each pulse. A higher heart rate variability (HRV) suggests a relaxed, low-stress physiological milieu, while a lower HRV indicates a need for recovery, rest, and sleep. That’s why athletes use HRV monitoring to plan their workouts and rest periods, PR attempts and deload weeks: it eliminates the guesswork. Even if you’re not an athlete, the HRV is a strong diagnostic biomarker for general health and resiliency. Today, we’ll be exploring 16 ways to increase it.

How to Deal with Health “Noise”

Among the most important truths I’ve come to believe over time is the need to be selective in life. Selective with relationships. Selective with experiences. Selective with purchases. Selective with information. Selective with messages (whether they come from outside sources or, on occasion, my own head). Like it or not, we have limited time and energy in a day – and in a life. While some people respond to this fact with frantic scurrying or a miserly parsing out of minutes, I’ve found the best approach for me is to winnow what I want or need to give attention to what’s most important. It’s part spirit of simplicity and part defense of sanity, particularly when you consider the deluge of bad news and marketing distraction that would snatch up every waking moment. Yet, it’s also more than that – Primally speaking. To maintain and enjoy my Primal lifestyle, I appreciate being able to live it with as much peace, space and clarity as I can. The more I can reduce the static – those extraneous and contradictory messages – regarding health matters, the more effortlessly and clearly I can tune into the programming I want to embrace in life. But what does that process look like, and how do I apply it? To be fair, what’s the difference between a selective and discerning perspective and just a closed mind? Let’s take this apart.

16 Ways Green Space Improves Your Life

Most people like being surrounded by nature. Even if it’s just a walk through a suburban city park or puttering about in a backyard garden, we’re drawn to green spaces filled with grass, trees, and leafy vegetation. They make us feel better. But the way we describe the effects of green space is all very amorphous and abstract and general, isn’t it? We “feel good” sitting on the grass. “It’s nice” to take a walk along a forest path. The office “doesn’t feel right” without a potted plant on the desk. Those sorts of benefits are great on a subjective level for the people experiencing them, but they aren’t very persuasive to others. If you want your ambivalent spouse to help grow the big garden you’ve always wanted, or your skeptical friends to start going on hikes with you, more specific and measurable reasons might be just the ticket.

So let’s dig deeper. Let’s explore the specific ways in which green spaces improve our lives:
