The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate in...
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
It’s been a long time since I published the Definitive Guide to Fish Oils.
Oh sure, here and there I’ve cited some research supporting the beneficial effects of fish fat, but it almost goes without saying that omega-3s are important. Everyone knows it. Even the most curmudgeonly, conventional wisdom-spouting, statin script-writing, lifestyle modification-ignoring doc will tell you to take fish oil. And research in the last few years has not only continually confirmed the health advantages but illuminated new applications—and new physiological explanations—for their essential function in the body.
But what are those benefits, exactly? Why should we be eating fatty fish or, barring access to high quality edible marine life, taking fish oil supplements?Read More
You can “hack” a lot of your health, diet, and lifestyle. You can cook the entire week’s meals ahead of time, buy high-quality prepackaged foods and ready-to-cook meals, cover your nutritional bases with smart supplementation. You can condense your training time by choosing the right exercises and upping the intensity to a sufficient level. You can fast-track your stamina in a fraction of the time with sprints and intervals.
But you can’t hack sleep. There are no shortcuts to sleep. You can’t escape the need for 7-8 hours (perhaps 4-5 if you’re genetically gifted). The human body needs those hours. The human brain needs those hours to pick up trash and clean up around the cranium. And it needs to arrive at them naturally.
Yet, we try to hack it just the same, with terrible results.Read More
Humans are a tribal species. We form alliances, align ourselves along ethnic, familial, religious, and cultural lines. Still, for the vast majority of people, “tribal” carries a negative connotation. Bitter partisan politics, ethnic genocides, religious wars, and the long history of bigotry make that connotation almost unavoidable. But I don’t think tribal in its true essence is all bad. The basic instinct to form and belong to groups is a simple fact of human physiology. It’s how we work, so we’d better make it work for us.Read More
Even after I fixed my diet, ditched the chronic cardio, and cleaned up my overall lifestyle to be more in line with our evolutionary upbringing, one big problem remained: my response to stress.
This had always been an issue for me. Part of it was that I kept a full plate at all times. Whether it was my training load, my businesses, my overall type A personality, stress was simply unavoidable, I thought.
How did I approach the situation and manage my stress differently over time?Read More
Both fasting and carb-restriction appear to operate along similar physiological pathways. Both lower carbs. Both increase fat-adaptation. Both have the potential to get you into ketosis. Both lower insulin and blood sugar.
But is one better than the other? Are there certain scenarios in which an intermittent fasting protocol works better than a low-carb diet, and vice versa?
Let’s find out if the distinction matters.
And what scenarios are most impacted by any difference.Read More
As humans, our most important bodily endowment isn’t our claws, sharp teeth, powerful haunches, iron grips, prehensile tails, venomous secretions, or aerosolized musk. It’s the brain. We use it to shape the world around us, to bend physical reality to our will, to manipulate matter and create powerful technological terrors. These days, the human brain is more important than ever. If you want to enjoy life, pursue and succeed at your passions, to conquer your little corner of reality—you need a healthy brain. Brain health is key to total health—and quality of life.
By some analysis at least, however, neurogenerative diseases remain on the rise and take an ever more extreme emotional and economic toll. So, how do we keep our brain health intact? While much of it comes down to doing the things that keep your brain healthy and avoiding the things that harm it—exercising instead of sitting on the couch, breathing exclusively fresh air instead of tobacco smoke, sleeping instead of staying up—another big variable is the food we eat.Read More
My staff and I are quite close. Things stay busy these days, so there isn’t a lot of downtime, but I’ve worked with some of these folks for over a decade. We don’t discuss every grisly detail of our lives with each other. But we do share. We care about each other.
So when one of the Worker Bees mentioned he was having some potentially serious medical issues, I asked for details. Turns out he went to his doctor for a hard lump on his throat that was getting progressively bigger. Initial pokes and prods were inconclusive. An MRI led to a biopsy, which led to an email in the middle of the afternoon with the results and a hell of an opener: “This may be a cancer.” May helped. It wasn’t a sure thing yet.Read More
For today’s edition of Dear Mark, I’m answering three questions from readers. I’ve come down hard against phones in bedrooms in the past. Is there a “good way” to use your phone in the bedroom? Reader Kathy offered some good reasons for keeping a phone there; what do I think? Next, HealthyHombre laments having to take antidepressants (but he shouldn’t lament). And finally, I cover the differences in omega-6 between pastured eggs and conventional eggs.

I can’t complain about my existence in modern culture. My life is great. I have a loving family. My kids are happy and successful. My wife is a friend and lover and confidante and partner. Business is good and interesting. I care about what I’m doing. Every day is meaningful—and unburdened by concerns around mental well-being. Depression isn’t an issue for me.
But it’s not the case for everyone. The numbers don’t lie. Depression rates are climbing. Antidepressants are among the most common drug prescriptions, even among children. And because it can be embarrassing to admit you’re depressed—like there’s “something wrong” with you if you say as much—many people with depression never seek help, so the real numbers could be even higher. Depression isn’t new of course. The ancients knew it as “melancholia,” or possession by malevolent spirits. But all evidence suggests that depression is more prevalent than ever before.

With 6.1 million children in this country bearing a past or present ADHD diagnosis, it’s little wonder folks had a lot to say in the initial post I did on the subject a few months back. For the most part, people were pumped to discover new potential therapies for themselves or loved ones, or at the very least to find validation in their own hunt for side effect free ADHD treatment. Others questioned the validity of certain alternative approaches, and still more posed questions about other treatments they’d heard about or were interested in.
Is there any substance to the other alternative therapies I added in passing within that previous post? What else shows promise? Let’s dig in….
