Why Fast? Part Five – Exercise

In previous installments, I’ve discussed the powerful effect of fasting on weight loss, particularly with respect to adipose tissue. I’ve explained how intermittent bouts of going without food have been shown to increase cancer survival and resistance and improve patient and tumor response to chemotherapy, and I went over the considerable evidence suggesting that fasting […]

Is Eating Meat Ethical?

By now, you’ve probably heard about the essay contest the NY Times is running. The prompt is “Tell us why it’s ethical to eat meat.” To decide the winner or winners, they’ve assembled a diverse mix of self-hating omnivores, self-hating sometimes-vegetarians, self-hating “flexible vegans,” and the guys with all those witty one-liners about food and […]

Maybe There is Such a Thing as Too Much Information

A couple weeks back, the LA Times published a piece on a geneticist’s experience with “personalized medicine.” Based on careful and constant monitoring of his sequenced DNA and around 40,000 health markers – or “omics” – over 14 months by a team of his colleagues, Stanford geneticist Michael Snyder observed in painstaking detail exactly what […]

Why Fast? Part Three – Longevity

A time-honored and research-tested way to extend an animal’s lifespan is to restrict its caloric intake. Studies repeatedly confirm that if, say, a lab mouse normally gets two full bowls of lab chow a day, limiting that mouse to one and a half bowls of lab chow a day will make that mouse live longer […]

12 Tools That Can Help You Achieve Your Health and Fitness Goals

Last month, I wrote a couple articles on akrasia, or the phenomenon of acting against one’s own better judgment. First, I introduced the concept and described a bit of research surrounding it. Then, I discussed 8 reasons a Primal eater might suffer from food-related akrasia, including cravings, nutritional deficiencies, and mismatched Paleolithic genes trying to […]

Why Fast? Part Two – Cancer

“Everyone has a physician inside him or her; we just have to help it in its work. The natural healing force within each one of us is the greatest force in getting well. Our food should be our medicine. Our medicine should be our food. But to eat when you are sick is to feed […]

Can We Feed the World on the Primal Blueprint Diet? – Part 3

Regardless of how well Primal living has worked for you, you’re eventually bound to hear something like the following: “Sure, you’ve lost a hundred pounds, ditched your statins, regained your fertility, doubled your squat 1RM, gotten your diabetic cat off insulin, saved a couple hundred bucks on fancy shampoos, traveled to Southeast Asia and had no problems with the squat toilets… […]

Can We Feed the World on the Primal Blueprint Diet? – Part 2

Last week, I opened the discussion of whether or not the whole world could go Primal. As you may recall, I noted that given the realities of our infrastructure, our policies, and the entrenched interests who wield considerable amounts of power and influence, practically speaking such a dramatic shift simply isn’t likely anytime soon. While […]

How to Go Primal with Food Allergies and Restrictions

Over the past couple months, I’ve steadily been accumulating questions from readers with food allergies and food restrictions looking for assistance. They are all interested in giving the Primal Blueprint lifestyle an honest shot, but because they can’t eat certain foods, many of which enjoy an (real or imagined) exalted place in our community, they […]

Dear Mark: Do Perfect Foods Exist?

Today’s Dear Mark post touches on a concept that many of us have pondered: the perfect food. That is, does such a thing even exist? What with phytates, lectins, easily-absorbed fat-soluble vitamins, allergenic proteins, and all the rest, it sometimes seems like every good food has a crippling downside. If you read too many health […]

Dear Mark: Glucosamine, Chondroitin, and MSM; Iodine for Thyroid

Today’s edition of Dear Mark is a relatively focused one, with just two topics. I spend the bulk of my time discussing the merits of glucosamine, chondroitin, and methylsulfonylmethane supplementation when it comes to treating osteoarthritis. This is a tough subject, because while these joint supplements are some of the most commonly taken, the evidence […]

Dear Mark: Should I Consume Caffeine Before My Workout?

In today’s edition of Dear Mark, I cover a topic near and dear to many of your hearts: caffeine. But I don’t just cover caffeine; I explore whether caffeine truly does act as a diuretic, especially during exercise, and whether or not caffeine can actually be helpful to athletic performance. Should we all be downing […]

Handicraft: The Ancient Tradition of Creating Things with Your Hands

Anyone who’s spent significant time creating with their hands – whether it be painting, carpentry, knitting, carving, building – can appreciate the distinctive satisfaction it evokes. (I’m using the term broadly.) Handicraft, as wide a spectrum as it can encompass, isn’t about routine chores or fix-its. There’s a difference between grudgingly doing your own home […]

Akrasia, or Why You Act Against Your Own Better Judgment

Akrasia: it’s the word of the day. It may be a 25¢ word, but it’s a concept with which we’re all familiar. Essentially, it’s acting against one’s own best interest. We’re not talking here about the noble, altruistic deeds that purposefully put others’ needs before our own. Akrasia encompasses that irrational, confounding state of mind […]

Is Honey a Safe(r) Sweetener?

I pride myself on making the Primal Blueprint an easy lifestyle to follow. If you were just starting out, you could easily read a few articles, do a couple hours of research, and start making positive changes to your diet, exercise routine, sleep schedule, or daily life immediately. You could ditch grains or replace some […]

Why You Should Eat Sulfur-Rich Vegetables

“Be sure to eat your sulfur.” When’s the last time someone told you that? Except for the Wahls talk, probably never. My mother certainly didn’t. Few people even know much about sulfur besides the whole rotten egg, fire and brimstone thing. It’s a mineral with a role in our physiology, but it doesn’t showboat like […]

Dear Mark: Flexibility vs. Mobility, Orange Skin, and Radioactive Matcha

I’m going to keep today’s question and answer session rather brief. I’ll be covering three topics: flexibility and mobility; carotenoderma, or the orange-ing of the skin following ingestion of carotenoid-containing foods; and whether matcha green tea from Japan poses any threat due to radioactive contamination. For the first, I discuss whether it’s flexibility or mobility […]

The “Asian Paradox”: How Can Asians Eat So Much Rice and Not Gain Weight?

How the Primal community loves the concept of a dietary paradox. How we eagerly point to its various manifestations as supportive evidence for our way of eating, living, and moving. You know the French Paradox and how it confounds the experts. To mention all those smug surrender monkeys with their brie and their butter and […]

Why the Night Sky Matters: The Ramifications of Light Pollution

Carrie and I are lucky enough to have a hot tub in our back yard, overlooking a pretty spectacular ocean and mountain view. We often soak for a while and talk about the day’s activities just before retiring to bed (I sometimes alternate with a quick plunge or two into our unheated pool). Last night […]

The Pill: What You Need to Know About Oral Contraception

Over the years I’ve received questions about the Pill on a pretty steady basis. As one female reader put it, if you go Primal and do all the work of normalizing your hormones, does taking the Pill undo all the good? Are the cautionary rumors I hear just overblown, or are there substantial risks? What […]
