Dear Mark: Is Caloric Density the Answer?, Fat Starving the Brain, and High-Intensity Primal Endurance Training

For today’s edition of Dear Mark, I’m answering three questions from readers. First, should the primary focus in constructing a healthy diet be caloric density? Is the key to weight loss and optimal health the consumption of bulky, low-calorie foods? Next, a new study seems to show that fat “starves the brain.” Is this true? […]

Dear Mark: Saturated Fat Jet Lag, Collagenous Amino Acids, and Different Cutting Diets

For today’s edition of Dear Mark, I’m answering three questions. The first concerns a recent study seeming to show that saturated fat disrupts our circadian rhythms, especially saturated fat at the wrong time of day. Should we—yet again—trade butter for soybean oil? Second, how necessary are the amino acids found in collagen? Aren’t they found […]

Dear Mark: Just Outside of Goal Weight, Skipping Breakfast and Coffee, and Quark

For today’s edition of Dear Mark, I’m answering four questions. First up, I discuss what to do—and really, what not to do—as you approach your goal weight but keep coming up short.

Dear Mark: Staying Aerobic, Glycogen Depletion, and Sleep-Low for Strength Training?

For today’s edition of Dear Mark, I’m answering three reader questions. First, do anaerobic workouts—sprints, lifting, etc.—interfere with your ability to become a fat-burning, aerobic beast, or can you integrate them? Next, in last week’s post I talked a lot about glycogen depletion in the context of the “sleep-low” carb partitioning. How can we actually […]

Dear Mark: Red Blood Cell Fatty Acid Content and Obese Paleo Figurines

Dear Mark: Do High Protein Diets Cause Colon Cancer?

For today’s edition of Dear Mark, I’m talking about a new rodent study has just been released that seems to identify the general low-carbish, Primal-ish way of eating as bad for GI tract health.

Dear Mark: Paleo Diet Fattening?

For today’s edition of Dear Mark, I’m answering one question. It’s a burning one, though, judging from the deluge of emails I’ve received in the past few days.

Dear Mark: How Many Sprints Per Week, How to Play and Train with Babies, and the Best Nighttime Snack

For today’s Dear Mark, I’m answering three questions. First, how often can a person sprint safely and effectively? There are many factors to consider when determining the amount of sprinting a person can handle each week, like stress levels, sleep, and other training, so it’s tough to give a specific number. Next, what are new parents […]
