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...

Weekend Link Love – Edition 195

Our favorite The Atlantic contributor doubles down on her campaign against low-carb, high-fat, erecting a pretty impressive strawman in the process.

I’ve been railing against the idea that we need to be constantly drinking water ever since this one time during the Kona Ironman. See, I lost my hold on third place down the stretch because I had to stop to relieve myself of the 30 bottles of Exceed/Gatorade/water I’d downed out of fear of dying of dehydration. It was the longest piss I ever took. Famous exercise scientist Tim Noakes agrees with me.

Dishwashers get dishes cleaner than hand washing, but does it actually matter for our health?

Taco Bowl with Crispy Kale Chips

One-bowl meals, like this taco bowl, are a great example of achieving maximum flavor with minimal effort. When all the ingredients for a meal are piled on top of each other in a bowl, every bite brings a delicious new combination of flavor. Plus, every bite is packed with protein, healthy fat, and a variety of vegetables. And, it’s ridiculously easy to make.

Start by mixing up a batch of taco seasoning. It’s a bold but not overpowering spice blend that can be used to season any type of meat, or vegetable for that matter. Double the recipe if you like, then store extra in your spice drawer to season other meals.

What Does It Mean to Be a Fat-Burning Beast?

It’s Friday, everyone! And that means another Primal Blueprint Real Life Story from a Mark’s Daily Apple reader. I’m excited to be able to bring you this story today. As much as I’m not a fan of Chronic Cardio, I understand that a lot of people are interested in pursuing endurance events. I get it. I used to be one of them. More and more, now, I’m convinced there is a way to do it in a low-carb environment without sacrificing health, and I’m working on a book due out at the end of next year entitled “Primal Endurance” that explores how to do it. Stay tuned!

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!

My wife Cynthia and I embarked on a six month journey and discovered what it means to be Fat-Burning Beasts. We have been intrigued with discovering answers to questions like “what is the protocol, how would we know if we have achieved Fat-Burning Beast status, what is the body’s response, and ultimately, how far can one push the limits of a Fat-Burning Beast? On our journey in answering these questions, we lost weight…our percent body fat dipping by 7 points, we improved sleep, seasonal allergies all but disappeared and we improved our mental acuity. But the greatest gift of all has been passing on the keys to better health and ultimately happiness to family, friends, and co-workers who we have inspired enough to explore for themselves the Primal Blueprint.

How to Conduct a Personal Experiment: Yellow Light Exposure (plus an Announcement)

You guys ready for another personal experiment? I hope so. Even if don’t think you’re ready to take something on, I’m confident you’ll be able to handle this one, because it’s relatively simple, intuitive, and easy. It’s also something I’ve been discussing for a couple years now, so you’re most likely familiar and comfortable with the concept. But most importantly, today’s experiment is a gentle one that requires very little commitment. No jumping in freezing cold water, no drastic changes to your sleeping schedule. All I’m asking you to do is experiment with nighttime yellow light exposure.


Remember how I wrote about nighttime exposure to blue light affecting melatonin secretion and, subsequently, sleep quality and duration way back when? Yeah, that. In case you didn’t read it, I’ll give a quick explanation:

Is It Primal? – Cod Liver Oil, Sunflower Butter, Mead, and Other Foods Scrutinized

It’s time for another round of “Is It Primal?” This time, I’ll be covering six questionable foods. First, I tackle whether or not cod liver oil has a place in a Primal eater’s pantry (or fridge), and whether standard cod liver oil is worth it. Then, I get into the suitability of mead, that honey wine popularized by the Vikings, followed by maple syrup. Is it another “safer sweetener,” just like honey, or is it sugar masquerading as a health food? After maple syrup, I dig into pectin, binder of jam and jelly; and sunflower butter, also known as sunbutter, a popular replacement for peanut butter. Finally, I scrutinize the food about which literally everyone in the Primal blogosphere has been wondering, the food that’s getting an entire panel at the 2012 Ancestral Health Symposium, the food that we’ve all been eying in the meat section: camel meat.

Let’s get to it.

Dear Mark: Women and Intermittent Fasting

Many differences exist between the two sexes. We look different. We sound different. We dress differently from each other. We like different things. Different genres of movies cause men and women to cry (differently). And although society, media, and culture drive and/or inform many of our differences, some are inherent and physiologically-driven. For example, men and women have different biological equipment – both external and invisible to the naked eye – that change how we interact with and respond to our environments, our exercise, our sleep, and our eating habits. Nowhere are these gender differences more evident than in the realm of health and nutrition, and yet it seems that I’ve overlooked a big one: different sex responses to intermittent fasting.

Let’s take a look at a couple recent reader emails:
