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...Tell Me More
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.Read More
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.Read More
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.Read More
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.Read More
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.Read More
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.Read More
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.Read More
Most people chalk urinary incontinence and excessive urgency up to age. We get old, stuff stops working, we wake up to wet sheets. Cue jokes about adult diapers and investing in “Depends” futures. It’s not entirely out of line. Aging matters. There’s just more to it. Like other aspects of “aging,” incontinence and unreasonable urgency don’t just “happen.” Aging may hasten or accompany the decline, but it’s by no means inevitable, unavoidable, or unmitigated.
There are surgical treatments available, many of which involve the implantation of balloons and slings and rings and hammocks. Those are beyond the scope of this post, which will focus on exercises and other less invasive interventions and preventive measures.Read More
I’m 65, and though I’ve been able to stave off the worst of what normally passes for the “aging process”—as can almost anyone by paying attention to how you eat, sleep, train, move, and live—the fact remains that I’m not training like I used to.
It’s not so much that I’m “losing” a step, although it happens to the best of us. It’s that I’ve totally transcended the need or desire to train hard for the sake of training hard. There are no more competitions. My ego is content on the training front. I’m not wrapped up in pounds lifted or miles run.Read More
Yesterday, I linked to a study showing that the beneficial effects of high levels of cardiorespiratory fitness—the kind you build with cardio/endurance training, HIIT, and sprints—have no upper limit. At first glance, this study appears to bust the “myth” of chronic cardio and the U-shaped curve of endurance training and prove that the more you train, the longer you’ll live. This appears to run counter to some of my central claims—that too much mid-to-high intensity endurance exercise leads to burnout, health issues, and diminishing returns.
A commenter wrote a great comment that got me wondering:Read More
