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...

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.

8 Primal-Friendly Flours

While I don’t recommend making Primalized versions of grain-based foods a staple, the fact remains that people love them. They’re going to want them. There’s not much you can do about that. And if we want to incorporate pancakes, muffins, cookies, and other flour-based items into our diets without ruining everything we’ve worked toward, we need the healthiest, most Primal flours.

The alternative flour market has exploded in recent years. A decade ago, you had gritty almond flour and fibrous coconut flour, and that was about it. Today, there are many more flours to sift through. But what are the best ones? Which ones fit best into a Primal way of eating, and why?

Dear Mark: Roundup Safety and Polyamory to Monogamy

For today’s edition of Dear Mark, I’m covering two entirely different topics. The first is a fairly familiar topic to readers of this blog—whether a popular pesticide is actually dangerous or not. The reader asking the question thinks the data is clear, and Roundup is safe, but I’m not so sure. Second, I discuss the evolutionary underpinnings of our transition from polyamory to monogamy.

How Your Oral Biome Influences Your Overall Health

In response to my post on oral health a few weeks ago, one reader offered a comment about the oral biome, and it’s a worthy follow-up, I’d say.

The human oral cavity is home to hundreds of microorganisms. Latest estimates place the number of bacterial species in your mouth at close to 700, with the odd fungus, protozoa and even virus thrown in for good measure. This oral microbiome isn’t a whole lot different than that of our gut, but where things get interesting is when we consider the diverse range of habitats within the mouth: teeth, tongue, cheeks, gums, tonsils. All provide different living conditions for those microorganisms that colonize them, but that diversity of habitats also encourages a diversity of species.

7 Reasons to Love Wheat

Wheat gets a bad rap in the alternative health sphere, receiving blame from all sides. Today, I’m here to provide the other side. Today, I’m going to give you seven solid reasons to love wheat, ranging from its effects on the environment, its role in the foundation of the American republic, its effect on gut bacteria and your health, its ability to stamp out hatred, its protective role in the lives of Bronze Age Chinese women, and its status as an enduring symbol of human rights and prosperity.

Dear Mark: Erythritol and Weight Gain, Chicken Liver and Arsenic, and Tips for Laptops in the Sun

For today’s edition of Dear Mark, I’m answering three questions from readers. First, is erythritol, one of the more common sugar alcohols, linked to weight gain? According to a new study, it is. What should we make of the research? Next, I talk a good game about chicken livers, but there’s a new study that seems to show they’re big repositories of arsenic. Should you stop eating chicken liver? And finally, I give a few tips for improving screen clarity when working outside on your laptop in full sun.
