Dear Mark: Glycine as Collagen Replacement; Debt as Disease of Civilization

For today’s edition of Dear Mark, I’m answering two questions. First, since glycine is often cited as the main reason to consume gelatinous meats and take collagen hydrolysate supplements, couldn’t we just take supplementary glycine? Are we missing anything if we go that route? And second, I riff off a great comment from last week’s post on financial security.

Dear Mark: New Coffee Study, Letting a Fever Run its Course, Collagen Dosage

For today’s edition of Dear Mark, I’m answering three questions from readers. First, I give my take on a new, big coffee study, which analyzed several meta-analyses of existing coffee and health data. Second, should you let a fever run its course or try to defeat it at all costs? The body obviously “wants” to get hotter in these situations. Is there a good reason? And finally, how much glycine do people need per day?

Dear Mark: Mostly Questions About Collagen

For today’s edition of Dear Mark, I’m quickly answering a bunch of questions from readers. Most are from the comment section of last week’s collagen post, and others concern different topics. They’re all interesting and useful, including how I consume podcasts, gelatin loss during chicharrone production, adding collagen to hot coffee, how much vitamin C to take with collagen, collagen’s effect on ketosis, and why I include a processed food product like whey in the pantheon of Primal-friendly foods.

Dear Mark: Insulin Response of Whey and Cancer

For today’s edition of Dear Mark, I’m answering one reader question. It’s an important one from last week’s post on insulin and illness. Given the potential effects of excess insulin on cancer development and growth, should we be worrying about the insulinogenic effects of a food like whey protein—which is one of the most insulinogenic foods of all? I sell the stuff, so I’d better know what I’m doing. Do I?

Let’s find out.

Dear Mark: Gender and Retirement Mortality, Muscle-Sparing Keto, Freezing Keto Recipes, Net Carbs, and Carb Timing

For today’s edition of Dear Mark, I’m answering 5 questions from readers. First, are there differential mortality effects of mortality on men and women? What role do social networks play? Second, is ketosis muscle-sparing? Yes, and here’s why. Third, which of the recipes in Keto Reset can be made ahead of time and frozen? We’ve got some busy parents here, after all. For the fourth question, I clarify my stance on net carbs and whether or not to count vegetables. And last, I explain how is is not necessarily ought.

Dear Mark: Keto Carb Timing, Fat-Burning Aerobic Zone, Stored vs Dietary Fat

For today’s edition of Dear Mark, I’m answering three questions from readers. First, why do I recommend that keto dieters (and low-carbers in general) position their carbohydrate intake shortly after their workouts? If it’s to refill glycogen stores, aren’t they already depleted by virtue of us being low-carb? Second, do my current 180-age aerobic HR recommendations clash with the original PB “move frequently at a slow pace” recommendations? And finally, how does the body decide what to do with stored versus dietary fat?

Dear Mark: Fish Oil and Exercise, Skipping Breakfast Study

For today’s edition of Dear Mark, I’m answering two questions about two recent studies. First, given that the omega-3 alpha linolenic acid (ALA) has been shown to reduce some of the positive effects of exercise on rats’ metabolic health, could the omega-3s found in fish oil (DHA and EPA) also nullify exercise benefits? Second, what are my thoughts on the recent study showing a link between breakfast skipping and subclinical atherosclerosis?

Dear Mark: Is Keto Ancestral, Ketone Breath, and Keto for Lupus?

For today’s edition of Dear Mark, I’m answering some questions about keto (hey, you folks keep asking!). First, is being on a ketogenic diet actually congruent with our ancestry? Is there historical precedent? Next, is bad breath really a reliable indication of being in ketosis? And finally, could going keto help treat the autoimmune disease lupus?

For today’s edition of Dear Mark, I’m answering questions from last week’s hormone normalization post. First I discuss a lack of purpose in the mornings affecting sleep and what to do about it. Next, I explore the prospect of sun and fasting as hormone modulators. After that, I explain the meaning of max aerobic heart rate and correct a mistake I made. And finally, I suggest to one reader that she may need to eat more calories to normalize her sleep and thus her hormones.
