Dear Mark: Vegetable Juicing, G_BOMBS, Blood Sugar, and Hot Workouts

Today is going to be a bit of a long Dear Mark blog post. I got some great questions from you guys. First, I cover three questions regarding the insulin spike and carb load from vegetable juicing. Next, I discuss the place of G_BOMBS, or the “perfect nutritional combination” of greens, beans, onions, mushrooms, berries, […]

Dear Mark: Bacon Fat Stability, Noise Machines, and Pig Feed

Is there any food more lauded and feared, beloved and bewitching, hated and praised – all at the same time – than bacon? Have full-fledged Internet subcultures sprung up around any other animal product? Does any food but bacon inspire obvious longing masquerading as righteous rancor and vitriol? And yet no matter how much has […]

Dear Mark: First Trimester Frustration, Liver Dosage, and NY Times Barefoot Piece

Being pregnant is tough – or so I hear. You’re tasked with creating a child, with actually building an entire human being bit by bit from scratch. You have to carry that child, even as it grows to seven, eight, or even nine pounds or more inside your body. And all the while, your body […]

Dear Mark: Beef Suet, Lowered HR, Alcohol, and Long Easy Runs

In today’s edition of Dear Mark, I answer a question about the nutritional viability of beef suet, which so many people assume is waste. Then, I address an extremely common occurrence around these parts: the discovery of one’s newfound ability to maintain a low heart rate at higher energy outputs. Next I cover a question […]

Dear Mark: Maximum 4,000 Calories a Week of Exercise?

Last week, I made the suggestion that people interested in maintaining health and immunity while avoiding excessive oxidative stress should expend no more than 4,000 calories per week through focused exercise, a recommendation that I’ve found to be pretty sound for most of the general population. You guys had plenty of questions about that recommendation, […]

Dear Mark: Managing a Cheat Day and “Raw” Almonds

We’re finally back in the swing of things. Back to the regular programming. It’s good to shake things up now and then, but there’s really nothing quite like getting back into your normal groove. Last week, I published a Dear Mark on a Tuesday, and it honestly sort of threw me off for the rest […]

Dear Mark: Ornish Strikes Again, Vitamin D from Light Boxes, and Kimchi and Cancer

Ah, it’s good to be back in the saddle again. The challenge was a lot of fun – don’t get me wrong – but ultimately both you guys and I come here for the dispensation of musings and information and writings and discussion on health, fitness, and any other number of lifestyle topics. So, let’s […]

Dear Mark: Why Do We Procrastinate and How Do We Beat It?

Do you procrastinate? If you’re an actual human being – not a replicant, nor an android, nor an AI – and you’re being honest, then you should probably be nodding your head. But what’s odd about a ubiquitous behavior like procrastination is that it’s almost unanimously regarded as being detrimental to our success, our happiness, […]

Dear Mark: Does Eating a Low Carb Diet Cause Insulin Resistance?

Despite all the success you might have had with the Primal way of life, doubts can still nag at you. Maybe it’s something you read, or something someone said to you, or a disapproving glance or offhand comment from a person you otherwise respect, but it’s pretty common when you’re doing something, like giving up […]

Dear Mark: What Are the Health Benefits of Negative Ions?

Anyone who’s been through a health store has heard about ions. If it’s not someone offering samples of ionized water, it’s someone selling ionized bracelets. It sounds wacky, woo-woo, crazy, and as if it belongs firmly in the same realm as crystals, magnet therapy, and cryptozoology (although the kid in me is still holding out […]

Dear Mark: Coffee and Insulin, Fat and Post-Workout Meals

In today’s edition of Dear Mark, I cover two topics near and dear to many of your hearts. First, I discuss the interaction between coffee intake and insulin. Does coffee stimulate its secretion? Does it impair insulin’s function, or our body’s reaction to it? Find out how you should approach coffee on a Primal Blueprint […]

Dear Mark: Industrial Duck, Topical Seed Oils, and Costco Rotisserie Chicken Bones

We can’t always make the perfect Primal choices. We simply don’t live in a world that affords us the opportunity, and short of being whisked away in the night by an elvish boy with green tights, a fairy companion, and the ability to fly, we’re stuck here for the duration. Let’s make the best of […]

Dear Mark: Should I Increase Carb Intake for Weight Loss?

Sometimes, weight loss slows. Sometimes, what worked amazingly well before, stops working quite the same. Although this can be scary, frustrating, annoying, or all of the above when progress slows, stops, or requires new input to continue like it was is ultimately okay, because we are an adaptive species. We can change things up, shift stuff […]

Dear Mark: Training Edition

I’m no stranger to spending the bulk of your time thinking about training, programming your training, planning your meals so that they support your training, modifying your training to affect your performance, and modifying your training to affect your body composition. I was an elite endurance athlete who dabbled extensively in strength training; I’ve been […]

Dear Mark: Too Much Coconut Milk, Donating Blood, De Novo Lipogenesis, and Distilled Water

The milk of the coconut enjoys an exalted position among in our community. We prize its ketone-generating prowess. We marvel at how it laughs off bile salts with nary a care and goes straight to digestion. Its tendency to shoulder aside longer-chain fats in the acetyl-CoA line doesn’t even come off as a jerk move. […]

Dear Mark: How Much Protein Can You Absorb and Use from One Meal?

Early last week, I received an email from a reader. The subject was protein absorption, and it referred to something I’d written several weeks past in this post on Leptin Reset among other things. I had suggested that your body can only deal with about thirty grams of protein in one sitting. I immediately realized […]

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, […]

Dear Mark: Personalizing the Primal Blueprint

Primal life is good. You’ve lost some weight, improved some health markers, enjoy steady even energy throughout the day, and you finally look forward to exercise (and movement in general) for the first time in a long while. You love the food, and the compliments you’ve started receiving since beginning to eat it, and you’re […]

Dear Mark: Women and Intermittent Fasting

Many differences exist between the two sexes. We look different. We sound different. We dress differently from each other. We like different things. Different genres of movies cause men and women to cry (differently). And although society, media, and culture drive and/or inform many of our differences, some are inherent and physiologically-driven. For example, men […]

Dear Mark: Preservatives in Lard, Ace-K, Raspberry Gorging, and Veal

What would you do if someone gifted you with a 5-pound tub of lard? Jump for joy? Grab a spoon? All reasonable responses, but what if that tub of lard had a label that said “contains BHA and BHT”, two antioxidants commonly used to preserve processed food, cosmetics, and pharmaceuticals – how would you react?
