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 […]

Dear Mark: Mysterious Omegas and a Beginner’s Exercise Routine

Today’s installment of Dear Mark covers two questions. In the first, a reader wonders whether or not all those mysterious omegas popping up lately are worth taking. Are omega-3s enough, or should we be supplementing with omega-5s, omega-7s, and omega-9s as well? Read on to find out. Then, I take on a question about exercise […]

Dear Mark: Fat Causes Brain Damage?

It feels good to get back to our regularly scheduled Monday morning programming. “Dear Mark” is a way for me to keep my finger on the pulse of the community, to respond quickly and directly to any issues that may arise. I try to keep abreast of all this stuff, but there’s a lot, and […]

How to Interpret Cholesterol Test Results

Before we get into the big job of interpreting cholesterol numbers, let’s review what cholesterol actually is. Cholesterol is cholesterol: a waxy steroid of fat that serves as an essential structural component of cellular membranes and in the production of steroid hormones, vitamin D, and bile acids. Contrary to what the terminology indicates, there’s actually […]

How to Eat More Fat

The leaders of the dietary establishment either keeled over or started arming themselves with pitchforks as I wrote that title. (It’s a good day to enjoy the subversion, I think.) On a serious note, let me unpack this worthy question – one I tend to get often: how does one incorporate more fat into a […]

Dear Mark: Egg Shell Calcium, Fully Hydrogenated Oils, HG Walking, Gorging, and Frozen Produce

This was a crazy week, eh? I offered up a brand new book and an accompanying special offer, and you guys responded. Although I’m not sure if we sold enough copies of The Primal Blueprint 21-day Total Body Transformation to make the New York Times best seller list (we’ll see and my fingers are crossed), […]

Managing Your Mitochondria

In Monday’s “Dear Mark” post, I briefly outlined a few of the benefits to having healthy, abundant mitochondria, and in the past, I’ve alluded to the damaging effects of statins on mitochondrial function. All good, yeah, but a couple brief paragraphs in the middle of a Monday post aren’t enough. Mitochondrial function and mitochondrial biogenesis […]

Does a High-Fat Diet Cause Type 2 Diabetes?

This is a special guest post from Denise Minger (thank you, Denise!). When fear-inducing news headlines hit the papers (and airwaves and iPads…) –  High-Fat Diet Linked to Breast Cancer, Eating Whole Grains Will Help You Live Longer, Fish Oil Linked to Prostate Cancer – she’s the person to go to for an honest and […]

How Many Calories Does Muscle Really Burn? (and Why It’s Not About Calories Anyway)

The hallowed halls of the Academy of Broscience contain untold tomes of knowledge, wisdom, and recipes for “sick” pump stacks. Over the years, their scholars have elucidated the arcane esoterica of muscle confusion, thereby making it palatable for the layman. They discovered that any gram of carbohydrate eaten after dusk turns immediately to fat, and […]

Dear Mark: MCT Oil, Camelina Oil, and Fancy Canola Oil

Today’s Dear Mark roundup is a trio of oil-related questions. Learn about my adventures with MCT oil and whether it fits into a good eating plan. Hear about camelina, the “better flax.” And finally, we’ll go over whether fancy, cold-pressed canola oil is worth including or whether it’s still just canola oil. I’m thinking I’ll […]

Dear Carrie: Cellulite

Hi again, everyone. Thanks for the comments and emails in response to my last post on menopause and hot flashes. I’m working on getting through your questions and hope to do several posts throughout the summer that speak specifically to issues that matter to women. Now that summer is here for most of the country, […]

Is Fish Oil Linked to Prostate Cancer?

This is a special guest post from expert study-dismantler Denise Minger. (Read Denise’s previous guest posts – Will Eating Whole Grains Help You Live Longer? and High Fat Diet Linked to Breast Cancer? – and her blog at Raw Food SOS.) Enter Denise… Like salmon? Pop fish oil? Got a prostate? Then listen up. A […]

Dear Mark: Glutathione, Workout Nutrition, Cartilage Regeneration, Pam, and the Best of the Worst

It’s another round of rapid-fire Q&A with reader questions this week. Ever wonder about olive oil in a spray can, or which meat to choose when dining out? Do you have joint issues, or questions about workout nutrition? These readers do. Read on to learn my answers to these and other questions. And if you […]

Dear Mark: Rancid Fat, Store-Bought Mayo and Rice Bran Oil

It’s been a while since I published a Dear Mark post and it’s been a fairly anemic news week, so I thought I’d address a trio of (related) reader questions. If you’ve ever wondered what it means for a fat to be rancid (both for the fat and your body if you consume it), whether […]

Defending Olive Oil’s Reputation

Olive oil’s reputation has been besmirched. It isn’t the magic life elixir fueling the teeming hordes of Mediterranean-dieting, crusty bread-eating, moderate wine-drinking centenarians, but it doesn’t deserve to be tossed in the trash heap with soybean, grapeseed, corn, and canola oils. I sense that it’s fast becoming a “fallen fat” among our crowd and I […]

Poor Sleep May Make You (and Your Liver) Fat

Ah, sleep. Nothing like a good dose of the stuff, right? Losing even a single wink of your usual forty (or an hour, as the case may be) is enough to throw off an entire day. But do you know who might love sleep more than anyone or anything? Our livers. Yes, livers. Those fleshy […]
