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.

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?

Let’s explore what else might be causing the problem.

Or are there instances where being in nature is far more stressful than being indoors? Why, and what should we do about it?

Dear Mark: Low-Fat Beats “High-Fat”; Prunes for Bone Health

For today’s edition of Dear Mark I’m answering a pair of great questions. First, Vaughn asks me about a recent study where ethnic Chinese participants were placed on several different diets, and those on the “low-carb, high-fat” one actually did worse than those on higher carbs and lower fat. Should you give up your low-carb approach? Then, I explore the bone-strengthening effects of prunes and discuss the Simon and Garfunkel diet.

Dear Mark: CrossFit and Carb Questions
