Hair Loss: Looking beyond Genetics

Conventional wisdom teaches us to accept our fate when it comes to hair loss. “Runs in the family,” we’re often told—and sometimes it does (but that’s usually not the full story). “It’s just part of getting older,” people say, too—and there we again find only partial truth at best.

In a few months, I’ll be releasing a book extolling the virtues of a ketogenic diet. I’m currently several months into a ketogenic experiment, which is going well.

You’d think I’d recommend that everyone go keto. Right?

Dear Mark: Alcohol and LDL, Liverwurst, Coffee and Milk, Kid Snacks, and High Carb Questions

For today’s edition of Dear Mark, I’m answering 14 questions. The first concerns the effect of alcohol intake on LDL. Does it increase it or lower it (or both)? Next, what’s the best liverwurst to eat? After that, I discuss whether drinking coffee with milk makes the coffee antioxidants useless, followed by a quick list of good snacks for kids.
