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: 21-Day Challenge Rapid Fire Edition

For one of the 21-Day Challenge contests last week, you guys asked dozens of questions. Today, I’m answering a bunch of them in rapid fire style including how to get kids to eat more meat and veggies, how to get adults to eat greens, whether keto can coexist with high-carb, if it’s better to eat seasonally and many, many more. Don’t expect long, drawn-out answers. I’m answering quickly and succinctly. If you have any further questions after hearing the answers, toss ’em in the comment section. There will always be more Dear Marks down the line.

Let’s get to it:

Dear Mark: Baby Sleep/Feed Schedule and Walking Through a Sedentary Society

For today’s edition of Dear Mark, I’m answering two reader questions. The first comes from reader Larisa. She is about to give birth, has been hearing the “wake your newborn every 2 hours to feed” recommendation, and wonders how realistic, evolutionarily-congruent, and healthy that will be for new parents desperate for sleep. I offer a few loose recommendations that hopefully make her feel better about what’s about to descend upon her life. Second, is there such a thing as too much low-level activity? Mariel walks 10+ miles a day, strength trains, and stands when she gets tired of walking. Her coworkers think she’s crazy. What do I think? Find out below.

Dear Mark: Do Hunter-Gatherers Sleep Less Than We Thought?

For years, we’ve thought that hunter-gatherers slept like babies: long and hard. They’d drift off as the sun dropped, lingering around the ubiquitous campfire only for a short time, sleep a good 8-10 hours, and waking up at first light bright eyed for the next day. For today’s edition of Dear Mark, I’m examining a study that calls these assumptions into question. What if hunter-gatherers don’t actually sleep any more than us? What if the absence of artificial light doesn’t lead to a ten hour session of blissful repose under the stars?

The A-to-Z Guide to Leading a Primal Lifestyle

Print this out. Bookmark it. Send it to friends who don’t quite get the Primal thing. Consider this a valuable resource for all-things Primal. It’s a nice, alphabetical encapsulation of what it means to lead a Primal lifestyle. It’s not everything, of course. You can always dig deeper into the details, but this summary gives a high-level look at just about everything.

Without further ado, I present The A-to-Z Guide to Leading a Primal Lifestyle.

Avoid chronic cardio. I spent about half my life running (and later, with triathlons, swimming and cycling) myself into the ground. I thought the more miles I could log, the healthier I’d be. That’s the mindset many people have, and it’s absolutely wrong. Running a ten-miler is different than running a ten-miler every day. We have the capacity to go long distances and even outlast wild animals upon which we’re preying. We don’t have the capacity to do that every single day without consequences to our health. Run long distances if you love it, compete if you love competing, but know the cost it incurs.

10 Things You Shouldn’t Do If You’re Trying to Build Muscle

While it’s important to think positive and focus on all the things you should be doing to achieve your goals, it’s equally important that we focus on those things that interfere with our goals and remind ourselves to avoid doing them. Some call it the “not to do list,” which I like. Many of the behaviors on not-to-do lists are deal breakers, so it’s arguably more crucial that we identify and curtail those that apply to our lives. But that’s hard; these are behaviors we might already be doing. Heck, they might be bad habits we’ve developed, or biases we’ve internalized. And so before adopting good behaviors, we should clear out the bad ones. Otherwise, we’re just pissing in the wind.

What are some things you shouldn’t be doing if your ultimate goal is to build muscle?

Dear Mark: Natural Energy Boosters, Designer Fruit, and How to Be Okay

For today’s edition of Dear Mark, I’m answering three of your question, dear readers. First, are there any caffeine-free ways to boost energy during a (really) long workday? Absolutely (but caffeine still might help). Second, what’s the deal with cotton candy grapes, a new designer fruit? Is it just junk food on the vine, or can designer fruits be a healthy part of a Primal eating plan? The last question comes from Shirley, a dedicated weight lifter and macronutrient-counter who’s tired of tracking and planning everything. She just wants to enjoy herself and be content with her body without all the calculation. How can she do it?
