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...

3 Ways to Regulate Insulin That Have Nothing to Do with Food

Today’s guest post is served by a good friend of Mark’s Daily Apple, Dr. Sarah Ballantyne, PhD, or as you might know her—The Paleo Mom.  

Regulating blood sugar levels is a key feature of any health-promoting diet [15, 20] . High blood sugar levels after eating are a major stimulator of reactive oxygen species (ROS), which are chemically reactive molecules that have important roles in cell signaling (the complex communication between and within cells) and in homeostasis (maintenance of a stable environment inside and outside the cell). But ROS are also potent signals for inflammation and stimulate the production of proinflammatory cytokines (chemical messengers), and also injure cells and tissue. As a result, chronic high blood sugar levels can cause serious damage throughout the body, including to blood vessels and vital organs. This is why diabetes (chronical hyperglycemia) is associated with higher risk of stroke, cardiovascular disease, vision problems, kidney disease, and nerve damage.

Summer Reset: 30 Days, 30 Actions (Plus a 21-Day Staff Challenge AND Giveaway!)

At the onset of our annual 21-Day Challenge this past January, I offered up a post that proposed thinking small—“41 Primal Action Items and Individual Experiments for Success in 2017.” The idea here wasn’t shrinking our scope to the exclusion of big visioning, but homing in on the day to day aims we can set for ourselves that make the big changes happen.

I think June is a good time to revisit that premise—and to host another 21-Day experience for those more inspired in the summer months.

Give Some Love to Your Hips

Today’s awesome guest post is offered up by a good friend to MDA—Ryan Hurst, Co-founder and Head Coach at GMB Fitness. I think it’s the perfect message for late in the work week when so many of us have been at our desks for too long. Enjoy, everyone!

Unfortunately, our hips don’t get as much love as they should nowadays. In our office culture world, most of us have to sit for hours at a time to get our work done. And even with well-meaning inventions such as standing desks and apps that reminds us to move around every so often, it isn’t enough to get us to move our bodies in the many varieties of ways that are possible.

10 Tips to Boost Your Serotonin

Serotonin is a major regulator of mood and depression risk. These are important, vital roles, to be sure. Your mood describes how you experience and interpret the world. If it’s consistently bad, you’regoing to have a rough time. Yet, serotonin is much more than the “feel-good hormone.” It also influences sexual desire and helps us remember. It’s the precursor to melatonin, the neurotransmitter that allows us to sleep.

How to Build Strength and Muscle with Progressive Calisthenics

Today’s guest post is offered up by some long-time friends of MDA, Al Kavadlo and Danny Kavadlo. I’m excited to share their expertise with the Primal community here. This year I wrote the foreword for their new book, Get Strong, which was just released. 

If you’re into Primal living, chances are you’re a minimalist when it comes to exercise. In our busy world, we all want to make good use of the time we allot to our training. Additionally, we Primal devotees know that many of the fancy machines we may encounter at the local globo-gym are not needed for building real-world strength.

Dear Mark: Hiking and Body Composition, Hiding Liver, Unconventional Testosterone Boosters, Cooked/Cooled/Reheated Potatoes, and Sirtuins

For today’s edition of Dear Mark, I’m answering five questions from readers. First up, why isn’t hiking giving one reader the shifts in body comp they expected? Two, is there actually a way to mask the flavor of liver? Then I discuss a few unconventional testosterone boosters, followed by a brief treatment of the cooked, then cooled, then reheated potato. And finally, are there any dietary activators of sirtuin proteins?
