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...

Collagen vs. Whey: Which Protein is Best For Your Needs?

Collagen or whey. Which should you choose?

For years, collagen/gelatin was maligned by bodybuilding enthusiasts as an “incomplete protein” because it doesn’t contain all the essential amino acids, nor does it contribute directly to muscle protein synthesis.  There’s definitely truth to this. If you ate nothing but gelatin for your protein, you’d get sick real quick. That’s exactly what happened to dozens of people who tried the infamous “liquid protein diet” fad of the 70s and 80s, which relied heavily on a gelatin-based protein drink. Man—or woman—shall not live by collagen alone.

As for whey, it’s an extremely complete protein. It’s one of the most bioavailable protein sources around, a potent stimulator of anabolic processes and muscle protein synthesis. I consider it essential for people, especially older ones in whom protein metabolism has degraded, and for anyone who wants to boost their protein intake and get the most bang for their buck.

This said, which is best for your needs today? Let’s take a look….

Is 50 the New 70? How the Modern Lifestyle Is Remaking Middle Age

“Do not go gentle into that good night.” That’s one of my favorite lines in all of literature, and it informs my outlook on health, life, wellness, and longevity.

Live long, drop dead. Compression of morbidity. Vitality to the end. All that good stuff.

But I’m sorry to report that Dylan Thomas imploring you to assail life with boldness is becoming harder for the average person to fulfill and embody. People more than ever before are heading into middle age with a head-start on the degenerative changes to body composition and function that used to only hit older folks. They may want to go boldly into that good night, but their bodies probably won’t be cooperating.

Does Diet Influence Menopause Timing?

Last week, I linked to a story about a popular vegan blogger, author, and influencer who found herself going into menopause at the age of 37 despite doing “everything right.” She exercised, she ate raw, she avoided gluten and refined sugar, and, most importantly, she avoided all animal products. Now, this wasn’t a randomized controlled trial. This wasn’t even a case study. But it was a powerful anecdote from someone whose livelihood depended on her remaining a raw vegan. It wasn’t in her interest to make it up.

So, it got me wondering: How do diet and lifestyle influence the timing of menopause?

Does Sleep Quality Really Decline With Age? (Plus, What I Do & a Giveaway)

One of the most common complaints people have as they age is poor quality sleep. They get less sleep than younger people, and, despite what you may have heard, their sleep requirements do not decline with age. A 70-year-old should still be getting 7-8 hours of sleep a night. The problem is that, for many different reasons, older people usually have issues getting the amount of sleep they need.

The popular approach is to accept poor sleep as an inevitable part of aging and find workarounds, ideally workarounds that require a lifelong prescription to a name-brand pharmaceutical. That’s not my way. I accept that the conventional approach may be warranted in certain cases, but it should be a last resort. A person should exhaust the diet, lifestyle, and exercise options before turning to the prescription pad.

Archetypal Resting Positions: How Sitting Like Your Ancestors Could Save Your Health

Tennis elbow, Achilles tendinitis, osteoarthritis, and other connective tissue injuries are on the rise. Athletes have always gotten them, but it’s only in the past few decades that regular folks are getting them too. For some connective tissue injuries, non-athletes outnumber athletes. That shouldn’t happen if the conventional wisdom—injuries to tendons, ligaments, and cartilage occur only because of overuse or overloading during intense physical activity—were true.

Now, of course the way we train affects the health and function of our connective tissue. Acute injuries absolutely occur. Overuse injuries absolutely develop. But that’s to be expected. Athletes put their bodies through a lot, and there is going to be fallout from that. Where those injuries shouldn’t be happening is in regular, everyday folks who don’t train for a living or engage in intense physical competition on a regular basis. And yet that’s exactly how it’s going down in the world today. In one recent study, the majority of patients with Achilles tendon injuries couldn’t attribute their condition to working out or playing sports. In other words, they just got it.

Top 10 Fasting Mistakes and How to Avoid Them

Folks, you know I’m a long-time believer in intermittent fasting for longevity, autophagy, mental clarity, fitness performance, metabolic health, and more. I’m excited that Dr. Jason Fung has stopped by the blog today to share a bit about common fasting mistakes. Enjoy!

So, you’ve decided to add some fasting to your lifestyle. Excellent. No matter how much you have (or haven’t) read on the topic, you’re likely to find aspects of fasting to be challenging or even frustrating. It can be hard to stay on track when you’re feeling hungry, irritable and not really noticing any changes.

It’ll become tremendously easier once you begin to experience the health benefits of fasting, but we all know it takes a little while for that to happen. Benefits like mental clarity and improved energy will show up sooner than significant weight loss. Plus, the benefits you experience will depend on what kind of fast you’re doing and how well you stick to it.

But if you’re making fasting mistakes, you might never accomplish the benefits you were hoping for. Before you throw in the towel, I want to help you identify some possible fasting pitfalls you might not be aware of and also help you avoid them. Plus, don’t miss the Number One reason fasts fail, shared at the end of this article.

The Definitive Guide To Autophagy (and 7 Ways To Induce It)

Biological systems are self-maintaining. They have to be. We don’t have maintenance workers, mechanics, troubleshooters that can “take a look inside” and make sure everything’s running smoothly. Doctors perform a kind of biological maintenance, but even they are working blind from the outside.

No, for life to sustain itself, it has to perform automatic maintenance work on its cells, tissues, organs, and biological processes. One of the most important types of biological maintenance is a process called autophagy.

Autophagy: the word comes from the Greek for “self-eating,” and that’s a very accurate description: Autophagy is when a cell consumes the parts of itself that are damaged or malfunctioning. Lysosomes—members of the innate immune system that also degrade pathogens—degrade the damaged cellular material, making it available for energy and other metabolites.  It’s cellular pruning, and it’s an important part of staving off the worst parts of the aging process.

10 Moves To Help Ease Joint Pain

Thanks for giving Jessica Gouthro from Paleohacks such a warm reception last week. I’m glad you found her “13 Ways To Move More At Work” useful. She’s joining us again today to offer tips for those who are looking to ease joint pain. Enjoy!

It sounds counterintuitive, but it’s true: one of the best ways to ease joint pain is to exercise!

Whether you’re feeling aches and pains in your elbows or your lower back and hips, the key to managing and preventing joint and muscle pain is to exercise in the right way. If you have existing pain or joint discomfort, then you need to keep your workouts low-impact, but that doesn’t have to mean easy or ineffective.

Does Vegetarian Collagen Exist?

I’ll start with the bad news: There are no vegetarian collagen sources. Every collagen supplement you see on the shelf came from a living organism. Though somewhere down the line someone will probably grow legitimate collagen in a lab setting, it’s not available today or for the foreseeable future.

Now, some good news: Vegans and vegetarians probably need less dietary collagen than the average meat eater or Primal eater because a major reason omnivores need collagen is to balance out all the muscle meat we eat. When we metabolize methionine, an amino acid found abundantly in muscle meat, we burn through glycine, an amino acid found abundantly in collagen. If you’re not eating muscle meat, you don’t need as much glycine to balance out your diet, but it’s still a dietary necessity.

Why Grip Strength Matters—and 10 Ways to Build It

The scientific literature is awash in correlations between a person’s health status and various biomarkers, personal characteristics, and measurements. As we hoard more and more data and develop increasingly sophisticated autonomous tools to analyze it, we’ll stumble across new connections between seemingly disparate variables. Some will be spurious, where the correlations are real but the variables don’t affect each other. Others will be useful, where the correlations indicate real causality, or at least a real relationship.

One of my favorite health markers—one that is both modifiable and a good barometer for the conditions it appears to predict—is grip strength.
