Hypertension is a problem. It raises the risk of heart disease; it’s one of the most consisten...
For today’s edition of Dear Mark, I’m answering three questions. First, is HDL all it’s cracked up to be? Is HDL always good? Is it the savior? Or is the story a bit more complicated? Next, what are some good probiotic options for treating acne? Do any exist? And last but not least, what’s the relationship of artificial sweeteners, insulin, appetite, and weight gain?

I was beginning to rest on my laurels. It had been months since the inbox had flooded with upset readers asking me to address the latest episode of the conventional establishment’s attack on healthy food and living. Until last week, when people starting freaking out about the American Heart Association’s attack on coconut oil. As USAToday put it, “Coconut oil isn’t healthy. It’s never been healthy.”
I was surprised. While I get most of my scientific references from USAToday (the “Works Cited” section of my upcoming keto book is just a single link to USAToday.com) and they’ve never let me down in the past, I didn’t know what to make of their coconut oil claims.Read More
I’ve written about extending your life by slowing down the apparent passage of time. I’ve written about some interesting predictors—but not necessarily causes—of longevity, and the common characteristics of centenarians. Today, I’m going to describe several unconventional causal means of extending your life.
I’m talking about cold, hard days, weeks, and months. Ticks on a clock. Objective measurements of time. Not just the perception of time, although that matters too.Read More
For years, the bodybuilding, protein-gorging community has maligned collagen for its inessentiality and lack of input into the muscle-protein synthesis process. From their perspective, it sort of makes sense. Why bother with “low quality” protein like gelatin/collagen when you can pound the whey, eat the meat, and focus on other sources of the essential amino acids directly involved in building muscle?
Except the research is showing that these “nonessential” proteins are actually pretty darn useful.Read More
For today’s edition of Dear Mark, we’ve got a two-parter. First up, I respond to a comment from last week’s Weekend Link Love concerning fat gain and lean mass loss in taekwondo athletes on a ketogenic diet. Did the athletes actually get fatter and lose muscle on their diet, even as performance improved? After that, I discuss what to do about dandruff and an itchy scalp. There may be no silver bullet against the common malady known as dandruff, but there are a few things you can try and one in particular that looks quite promising.

Last week, I introduced the concept of the skin biome: the vast communities of microbes living on and in our skin. For some, it was unsettling. Gut microbes are out of sight, out of mind. But skin microbes are on us. They’re crawling, reproducing, digesting, and secreting various fluids and lipids all over the surface of our bodies. In people who’ve been conditioned to use soap and water to remove every last trace of bacteria from our hands and skin, the idea that our hands, faces, arms, and torsos are teeming with microbes – and that it’s probably unwise to remove them all – is hard to swallow. We might even recoil at the thought. I mean, viruses and mites living on us? Really?Read More
The average human body has about 1.2 square meters of skin. Scattered across and nestled in its myriad crevasses and canyons would lie trillions of bacteria, fungi, viruses, and mites. Before you shudder and reach for the bleach and a stiff scouring brush, remember the importance of cultivating and supporting the billions of bacteria living in your gut. Recall the vital roles they play (that we know about) in our health and realize that the skin microbiome isn’t any different. Although research is young, we are learning that the critters living on our skin, who number in the billions per centimeter of skin, are supposed to be there. And even though we don’t know exactly all they’re doing, we know this:Read More
After I mentioned it in last week’s 10 Principles of Primal Living (Finally) Getting Mainstream Media Coverage post, several readers emailed asking about leaky gut. What is it? How do I know if I have it? Why should I care if I have it? What do I do if I have it? And so on. Turns out many and maybe most people have but a vague idea of what leaky gut actually means.
Today, I’m going to fix that.
In most popular conceptions of human physiology, the gut exists primarily as a passive conduit along which food travels and breaks down for digestion and absorption. It’s where bacteria hang out and digestive enzymes go to work. It’s a “place,” an inert tunnel made of flesh and mucus. Lots of things happen there but the gut itself isn’t doing much.Read More
Today’s guest post is from my good friend Tara Grant, truly a budding superstar in the Primal/paleo/ancestral health movement. Tara started out as a success story (“Tons of Doctors and No Solution” – one of the most visited stories in our entire archive; and also on the pages of the The Primal Blueprint 21-Day Total Body Transformation), and has leveraged her Primal success (she went from 245 lbs to 159 lbs in around 18 months in ’09-’10) like few others: She’s a veteran PrimalCon presenter, has delivered numerous Primal Blueprint Transformation Seminars, and recently completed a remarkable book called The Hidden Plague, which details the painful and poorly understood skin condition of Hidradenitis supprativa (HS).
Tara has become an underground legend in the online autoimmune community for helping people solve frustrating skin conditions such as HS (and assorted other autoimmune issues) with a methodically designed diet-based protocol that identifies trigger foods and promotes natural healing of the digestive tract and immune system. Her post today might resonate with many of us who deal with mild to significant skin issues the traditional way (lotions, potions, creams, prescriptions) with less than stellar results. For example, I flipped a copy of her food restriction protocol to a friend of mine who’s suffered from psoriasis and been under medical care for 40 years…She reported immediate and dramatic improvements after following Tara’s protocol. Enjoy Tara’s post and learn more about the book below…Read More
Two weeks ago, I introduced you to five cosmetics ingredients you should avoid. These are chemicals you’ll often find in things like shampoos, conditioners, deodorants, sunblocks, and makeups – you know, the stuff you’re covering yourself in everyday. Cosmetics manufacturers use these ingredients to improve their product’s ability to clean, moisturize, beautify, or improve an odor, but they often do lots of other bad stuff in the process. So the question is, do these products need these chemicals to work like we want them to, or are there alternative products that manage to use more natural and/or less harmful ingredients while still getting the job done? Indeed, there are, and today I’m going to share my findings with you.Read More
