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...

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?

4 Mushrooms You Need To Know

When you stop to think about it, mushrooms are remarkable.

They’re closer to animals than plants on the tree of life.

They can break down plastic and petroleum.

The single largest organism on the planet is an underground honey fungus spanning almost 3 miles in the the state of Oregon.

They carry messages along their underground fungal networks using neurotransmitters that are very similar to the ones our brains use.

They’re a kind of “forest internet” which plants and trees use to communicate with each other.

They’re delicious.

And, as it turns out, they possess and confer some very impressive health and therapeutic effects. Several years ago, I highlighted the culinary varieties and explored their considerable health benefits. Go read that, then come back here because I’m going to talk about the different types of adaptogenic mushrooms today. These are the real heavy hitters, the ones that appear to supercharge immune systems, stimulate neuronal growth, improve memory and focus, pacify the anxious mind, increase the libido, and enhance sleep quality.

10 Natural Anxiety Remedies

Anxiety is normal. It’s something we all have experience with—to one degree or another. Most people are anxious about something that hangs over them and follows them around like a personal rain cloud. Then there’s the deeper but still familiar anxiety many of us carry. The anxiety about our self-worth. The anxiety of performance, of social situations. This type can grip us in an uncomfortable, but hopefully not chronic, way. But not all anxiety is run-of-the-mill—or manageable. People with Generalized Anxiety Disorder, for instance, might have trouble leaving the house, ordering a coffee from Starbucks, going to work. Anxious thoughts cycling through their brains often keep them up at night. When untreated, people with this level of anxiety can end up living in a state of perpetual fear. The conventional approach is to take anti-anxiety meds, which can be genuinely life-saving for some people. Nonetheless, these can come with downsides that vary depending on an individual’s dosage and reactions—and the nature of the particular medication itself. Some meds result in few side effects, but others’ effects can be heavy. For instance, there are the benzodiazepines, highly-addictive tranquilizers with the potential for abuse. They make driving unsafe. They lower productivity. They sedate you. When necessary for the severity of the condition, these side effects may be worth it. In other cases, a person might have more space to experiment and want to explore a different route. In some cases, people choose to try natural anxiety aids. These are supplements, nutrients, and herbs that have been designed across millennia by nature (and maybe some input from green-thumbed healers). They might not always be enough for something as serious as a clinical anxiety disorder (please talk to your doctor before making any adjustment or addition to your medication), but at least some may be important complements to a prescribed regimen. For those who want or need an alternative strategy for anxiety beyond meditative practices and general good health, these natural remedies may be worth a try. First, the NUTRIENTS…. These are basic vitamins, minerals, and amino acids that your body needs to work. They are non-negotiable. You don’t have to get them through supplements—in fact, that should be a last resort after food—and I wouldn’t expect “drug-level” effects, but you do need to get them. 1. Long Chained Omega-3 Fatty Acids Some human evolution experts maintain that the human brain wouldn’t be the human brain without steady and early access to coastal food resources—fish and shellfish rich in long chain omega-3s. If the long-chained omega-3s found in fatty fish and other sea creatures made our brains what they are today, it’s safe to assume that our brains work better when we eat them today. And if we’re talking about anxiety, that appears to be the case: Studies in substance abusers find that supplementing with enough fish oil (and, yes, here’s what I use regularly) to raise serum levels of the long chain omega-3 fatty acid EPA reduces anxiety, while increases in DHA (the other long … Continue reading “10 Natural Anxiety Remedies”

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.

Keto and the Menstrual Cycle: Is There Reason To Worry?

It seems every “keto for women” forum abounds with stories about menstrual cycles gone wild in the first few months of keto. Irregular cycles, breakthrough bleeding, and periods lasting much longer than normal are common complaints. Sometimes these stories are cited as evidence that keto isn’t good for women, at least not premenopausal women, and that we need carbs for healthy hormones. Yet, many women don’t notice any changes in their menstrual cycles at all, while others report improvement in PMS symptoms and cycle regularity from the get-go.

What gives? Why do some women’s cycles apparently become wacky when they start keto, while others feel like keto is the key to period bliss? Can keto “mess up” the menstrual cycle?

4 Misunderstandings About Carbs and Stress

The relationship between stress and carbohydrates is confusing, with seemingly contradictory arguments bouncing around the online health sphere.

There are those who say high-carb diets cause stress, and that eating more fat and fewer carbs is the solution.

There are those who say high-fat diets increase stress and eating carbs ameliorates it.

Who’s right? They can’t both be right, can they?

Well…

You’d be surprised.

Let’s dig into four common carb questions and assertions.

Dear Mark: Fasting, Training, and Growth Hormone; Wear and Tear on the Arteries

For today’s edition of Dear Mark, I’m answering a couple of questions from the comment sections of the last couple weeks. First, it’s been established that fasting and exercise both raise growth hormone. What about fasted exercise—does that have an even stronger effect? And what about continuing to fast after your fasted workout? Then, I discuss the inevitability (or not) of wear and tear on the arteries from blood flow-induced shear stress. Is shear stress “bad,” or do certain factors make it worse?

Let’s dig in.

Male Menopause: What’s Behind Men’s Midlife Health?

It has many names and monikers.

Male menopause.

Andropause.

Age-related testosterone deficiency.

Hypogonadism.

Manopause, my personal favorite.

Although it isn’t as sharply defined as female menopause, male menopause is a catch-all for the gradual cascade of mental and physical health issues that men face as they approach and pass middle age and their testosterone drops. Wherever possible, I will insert “man” puns into the symptoms and conditions. Consider yourself warned.

Dear Mark: Pregnenolone

In today’s edition of Dear Mark, I’m talking about pregnenolone, the “master hormone.” Most of the hormones we talk about, like testosterone, estrogen, and cortisol, all have pregnenolone as their precursor hormone. What can happen when pregnenolone goes too low? Can taking pregnenolone solve any problems? Is menopause actually a pregnenolone deficiency?

Let’s find out….

The Pros & Cons of Hormone Replacement Therapy for Primal Women

A Primal woman’s first reaction to the prospect of taking synthetic hormone replacements for menopause? Probably a healthy dose of skepticism. We in the ancestral health community, after all, tend to view pharmaceuticals as a last resort—interventions that are overprescribed by vested interests, create their own set of side effects, and may even do more harm than good. To suggest that we “need” this or that prescription raises our hackles.

Besides, it’s not like menopause is a product of modernity or an aberration our ancestors never experienced; it’s a physiological stage that evolution has protected and selected in humans. It’s perfectly natural. Rather than the debilitating, miserable experience many women report having, menopause should be easier. Graceful, even. But it often isn’t.
