Dear Mark: Dealing with Undersleeping, and the Nutritional Value of Yeast

For today’s edition of Dear Mark, we’ve got two questions. First up is a big one: how do you deal with the inevitable bout of acute sleep loss? Are there pills to take, exercises to do or avoid, foods to eat or not? Or are we completely helpless in the face of undersleeping? And second, […]

Dear Mark: New Parent Issues, Corn, and Pain’s Purpose

For today’s edition of Dear Mark, we’ve got a three-parter. First, I draw on my experiences as a parent and observer of the new generation of Primal parents to tackle a big topic: how to maintain a Primal mindset as a new parent beset by all the crazy, often unreasonable demands of modern parenting. It’s not […]

Dear Mark: Two Weeks Off Primal, Pili Nuts, Fasting and Micronutrient Deficiencies

In today’s edition of Dear Mark, I cover three questions from readers. First is from Richard, who’s taking his father back to the old country – Italy, to be exact – for a two week vacation to visit the place of his birth where he’ll be immersed in pasta, sweets, and liquor and completely at […]

Dear Mark: Does Resistant Starch Cause Colon Cancer?

For today’s edition of Dear Mark, I’m handling just one question. I originally planned to answer more reader questions, but it turned into a complex answer that really made me dig deeper into something – butyric acid – I’d assumed was completely benign. I still do, mind you, for the most part. The position has just […]

Dear Mark: Constantly Falling Off the Primal Wagon, Frozen Produce, and A Few More Carbs

For today’s Dear Mark, I answer three questions from readers. First, I give some advice to a reader with a knack for doing a week or two strict Primal and then falling promptly off the wagon into a pile of donuts. How can she make it stick – or should she? Next, I extoll the […]

Dear Mark: Growing Appetite, Boxing as Cardio, and Ammonia Sweat

For today’s edition of Dear Mark, I’m covering three questions from readers. First, how does a Primal family handle the growing appetite of a growing prepubescent without resorting to cheap fillers? It may involve reassessing our definition of “filler,” for one. Second, does boxing – an intense, demanding sport by any measure – qualify as […]

Dear Mark: Sun Exposure and Eyesight; Vasectomies

For today’s edition of Dear Mark, we’ve got a quick two-parter. First, I discuss the pros and cons of ocular sunlight exposure in children (and adults). Should kids leave the house with a pair of wraparound goggles every single time, or are their prepubescent eyes safe without them? If too much sun exposure is bad, […]

Dear Mark: 1000 Calories a Day, No Appetite After Exercise, and How to Not Lose Weight

For today’s Dear Mark, I’m taking three questions. First, I comment on Mick Dodge’s (the barefoot forest-living guy with the beard on the NatGeo show) claim that humans can thrive on 1000 calories a day. Is it true? Next, I discuss whether or not people need to worry about a distinct lack of appetite following exercise. Should they […]

Dear Mark: Red Meat and Breast Cancer, Net Carbs, and Solutions for Excess, Unavoidable Sun

For today’s Dear Mark, we’ve got a three-parter. First up, I discuss the latest study claiming that red meat will kill us all. Or maybe it’ll be killing roughly half of us all, seeing as how this paper concerns red meat and women’s breast cancer risk. Next, I give my position on the “net carbs” […]

Dear Mark: Exercise and Gut Diversity; Pregnancy and Calories

For today’s edition of Dear Mark, we’ve got a two-parter. First up is a discussion of the latest (and only) exercise and gut flora study. It’s been making the rounds and even I gave it a brief mention in yesterday’s Link Love, but today I dig a little deeper. Find out what we can take […]

Dear Mark: Signs You Should Eat More Carbs

For today’s edition of Dear Mark, I’ll be addressing a single article from a highly-lauded intellectual institution: the Huffington Post. I’m kidding of course. The HuffPo has some great stuff, but they’ve also got to pay the bills and fluffy articles inevitably slip through the cracks. This article is one of the latter, claiming to give […]

Dear Mark: Young Guy, Low Testosterone; RS for Babies; and Sprints vs Tempo Runs

For today’s edition of Dear Mark, I answer three questions. First up is a young guy with low testosterone. He eats the right foods, does the right exercises, and has lived the right number of years, but he’s saddled with the testosterone of a much older man and wants to know why. Next, I discuss […]

Dear Mark: Does Dietary Acid/Base Balance Matter?

For today’s Dear Mark, I’m covering just one topic: the relevance of acid/base balance to health. Anyone wading through the morass of Internet diet information has come across the idea than an excess of acidity derived from our diet overloads the body’s ability to balance it with alkalinity. A diverse group invokes it, including strict paleo dieters, […]

Dear Mark: Are My Vibram FiveFingers Dangerous?

Today, I’m answering one hot-topic question for this week’s Dear Mark. It concerns an issue that’s inspired several dozen emails from readers: the Vibram FiveFingers lawsuit and settlement. If you want to skip ahead to the take home point, it’s that I’m not getting rid of my Vibram FiveFingers anytime soon. Heck, I’m wearing a […]

Dear Mark: IBS and Gluten, Tweaking Calories for Fat Loss

For today’s edition of Dear Mark, we’ve got a short but sweet two-parter. First up is the connection between Irritable Bowel Syndrome, gluten, coffee, and alcohol. A reader with a history of IBS triggered by gluten, coffee, and alcohol wonders if giving up gluten really could have solved his intolerances of the other foods. Then, I […]

Dear Mark: Leg Fatigue, Too Much Muscle Meat, Starch Persorption, and Hadza Study Author Responds

For today’s edition of Dear Mark, we’ve got four questions. First is a question from a reader who exemplifies the “between a rock and a hard place” situation inherent to chronic cardio. Second, I address a reader who worries that I’m not worried enough about exclusive muscle meat consumption. Third, I give my thoughts on whether […]

Dear Mark: Why Hyperglycemia Is Bad and Those Stubborn Final Pounds

Today we’ve got a fairly short one with just two questions and answers. First, I tackle a big topic: the specific effects of hyperglycemia on the body. That hyperglycemia is bad for us is implicit, but it’s important to understand why it’s so dangerous. Today, I give a brief but detailed overview of the negative […]

Dear Mark: Vegetable Powders, Pro/Prebiotic Timing, RS Questions, and Routine Eating

For today’s edition of Dear Mark, we’ve got four questions and four answers. First, I explain the merits and drawbacks of vegetable powders in the event of low produce availability. Next, I discuss whether there’s a perfect time to take your probiotics and prebiotics, or whether it doesn’t matter at all. After that, I answer […]

Dear Mark: Liver for Babies, Flax Seed, and MCTs with Fruit

For today’s Dear Mark, I’ve got a three-parter. First I discuss the suitability and proper dosage of grass fed beef liver for babies and toddlers. It’s definitely a good choice, but you do have to keep a few parameters in mind to do it right and do it safely. Next, I discuss flax seed. Is […]
