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?

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?

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.

Dear Mark: Really High HDL, More Heart Disease; Low-Salt For Grandpa?

For today’s edition of Dear Mark, I’m answering two questions from readers. They were excellent this week. The first one comes from Sarah, who’s a bit puzzled by the recent paper in which people with the highest HDL levels died earlier than those with lower levels. What’s going on, and is more HDL actually bad? Last but not least, how should a reader approach a doctor who wants to put Grandpa on a low-salt diet? Is there any literature or information he can present?

Dear Mark: Why are Male Fertility and Testosterone Levels so Low?

For today’s edition of Dear Mark, I’m answering just one question. But it’s a good (well, maybe not good, but certainly important) one: Why is male fertility on the rise and testosterone on the wane? The popular notion is that women flushing birth control pills and peeing estrogen-rich urine into the public water supply are the primary reasons for the sex hormone issues facing men, but I’m not so sure. Let’s explore what else might be causing the problem.
