Dear Mark: Nutrient Deficiencies and Fatigue, Anxiety, CLA Supplements, and Plant-Derived Oils

For today’s edition of Dear Mark, I’m answering four questions from readers. First up, are there any specific nutrient deficiencies that can contribute to fatigue? Which minerals and vitamins should you shore up when experiencing malaise? Next, what’s the deal with anxiety? Does it serve an evolutionary purpose, or is it just a pathological condition? […]

Is Constant Ketosis Necessary – Or Even Desirable?

Every day, I get links to interesting papers. It’s hard not to when thousands of new studies are published every day and thousands of readers deliver the best ones to my inbox. And while I enjoy thumbing through the links simply for curiosity’s sake, they can also seed new ideas that lead to research rabbit holes […]

What’s Messing with Your Appetite? Three Possibilities.

Although a few weeks ago I explained how “stop eating so much” is bad weight loss advice and how “calories in, calories out” tells us very little about the cause of obesity, the fact remains: for whatever reason (and there are many), people who gain weight have eaten more energy than they’ve expended. Something is […]

Dear Mark: Butter and Coagulation; Early Weaning and Growth Charts

For today’s edition of Dear Mark, we’ve got a quick two-parter. First up, I discuss the results of a 2008 study into the effect of high acute intakes of various fat sources on postprandial (i.e. after eating) blood coagulation markers. Since butter came out looking not so hot, a reader wonders whether this should impact […]

Dear Mark: Wife’s Weight Gain; Upper Arm Fat

For today’s edition of Dear Mark, we’ve got a two-parter. First up is a question from a reader whose wife has gained weight following the Primal Blueprint way of eating and after completing a Whole30. She seems to be doing everything right, in other words. What could explain the weight gain? Next, I discuss what […]

Why the Omega-3/Omega-6 Ratio May Not Matter After All

When it comes to omega-6 fats, the quick and dirty soundbite resonating throughout the ancestral health community has been “omega-6 fats are inflammatory, omega-3s are anti-inflammatory.” Years ago, I wrote a post saying essentially the same thing – that an excessive intake of omega-6s and inadequate intake of omega-3s predispose us to an exaggerated inflammatory […]

9 Signs You Need to Eat More Fat

By now, we all basically agree that fat is an essential nutrient. Certain fats, like linoleic acid and alpha linolenic acid, are physiologically essential because our bodies cannot produce them. Other fats, like those found in extra virgin olive oil and grass-fed butter, are culinarily essential because they make food taste really good (they’re not […]

Dear Mark: Cold Weather Sprint Alternatives, Palm Olein, Podcast Questions, and Dark Circles

For today’s edition of Dear Mark, we’ve got a four-parter. First, I discuss some alternatives to traditional outdoor sprinting for people in cold weather. Just because you can’t go run 100 meter dashes doesn’t mean you can’t get a fantastic sprint workout. Running is unnecessary. Next, I give my take on the suitability of palm olein […]

Should You Be Eating High-Fat Dairy?

One thing that sets the Primal way of eating apart from other ancestral health approaches is our acceptance of dairy fat. Obviously, those people who can’t tolerate dairy shouldn’t eat it, but in my experience a significant portion of the community can handle high-quality, full-fat dairy, especially butter, yogurt, and cheese. We like these foods for many reasons. […]

9 More Reasons You’re Not Losing Weight

A few years back, I wrote an article explaining 17 possible reasons why you’re not losing weight. It was a troubleshooting guide of sorts, aimed at helping people identify some of things they may be doing (or not doing) that’s causing their stalled fat loss. The etiology of obesity and weight gain is multifactorial, and […]

Dear Mark: Wheat and Asthma, Minimalist Winter Shoes, High-Fat Rat Cognition Study, and Sun Exposure Timing

Today’s edition of “Dear Mark” runs the gamut. The topics will be somewhat familiar, since I tackle wheat, minimalist shoes, high-fat diets in the news, and vitamin D, but with interesting spins on each. First, I discuss the link between wheat and asthma. Next, I do a somewhat exhaustive search of the available winter minimalist […]

Gender Differences in Fat Metabolism

A few months ago, I addressed the role gender plays in how we respond to intermittent fasting. That post sparked a great discussion, and I’ve since received a fair number of emails from readers eager to learn other ways in which gender plays a role in our health and nutrition. One email in particular set […]

What Does It Mean to Be Fat-Adapted? – Part 2: Q&A

As I figured it would, last week’s post on fat-adaptation generated a lot of comments and questions. I couldn’t answer all of them (maybe another time), so for today’s post, I tried to collate the most burning questions to arrive at a representative sample. That way I hit the major ones without making this one of […]

Dear Mark: How Much Glucose Does Your Brain Really Need?

We now know that the oft-repeated “your brain only runs on glucose!” is wrong. I’ve mentioned it before, and anyone who’s taken the time to get fat-adapted on a low-carb Primal eating plan intuitively knows that your brain doesn’t need piles of glucose to work, because, well, they’re using their brain to read this sentence. Obviously, […]

Why Did My Cholesterol Go Up After Going Primal?

While the majority of people who go Primal see their blood lipids improve, a significant minority do not in the short term. They see LDL cholesterol skyrocket, or their total cholesterol increase, and sometimes triglycerides even mysteriously elevate despite a low-carb intake. What’s going on here? Should you go on statins? Should you add grains […]

Top 7 Most Common Reactions to Your High-Fat Diet (and How to Respond)

A couple weeks back, I wrote about the top 8 most common reactions you get when people hear you don’t eat grains, and I offered up some concise responses to those reactions. It was well received, so I thought I’d do the same thing for “your high-fat diet.” If you thought having to explain your […]

A Primal Primer: Brown Adipose Tissue

Last week’s Dear Mark discussing cold thermogenesis got some of you asking about brown adipose tissue. It’s a topic that deserves a full-fledged Primal Primer, especially since the idea of “good” body fat, a term many use to describe brown adipose tissue (BAT), is a foreign one. I mean, we’re talking about body fat here. […]

Why Fast? Part One – Weight Loss

“When a person has nothing to eat, fasting is the smartest thing he could do.” – Herman Hesse, Siddhartha. I like that quote. It’s making (non-caloric) lemonade out of lemons, and for all the transcendental insights contained in Hesse’s book, this line strikes me as a really cool, no-nonsense way to make the best out of […]
