fasting

There’s a ton of talk about intermittent fasting in the ancestral heath sphere for general health and wellness as well as weight loss, but little indication of specific applications for the practice. Anytime you attempt a “radical” health practice like not eating, it helps to have a good reason to do it. That will not...

Cold season is upon us. Vitamin D levels are down. People are cloistered indoors. Kids are walking petri dishes. Drug stores are advertising free flu shots. It’s that time of year. I’m sure a few of you are even sniffling as you read this, or maybe trying to ignore the pain of swallowing with a...

For today’s edition of Dear Mark, I’m answering five questions taken from this Twitter thread. First, does collagen offer anything special above and beyond glycine? Second, what’s the relationship between keto and gallstones? Third, do I recommend eating raw liver, and why or why not? Fourth, why does one reader’s scalp itch when eating stevia?...

What are my specific recommendations for athletes who wish to explore intermittent fasting? I’ve got twelve…plus...

To the average person, the idea of elite athletes skipping meals sounds like pure madness. Athletes are fine-tuned, well-oiled machines. Machines need fuel. You don’t see race car drivers running on empty to “promote training adaptations” in their vehicles. No, high performance requires high energy reserves. Athletes need to eat, and eat well. Right? But humans aren’t...

I’ve covered plenty of other aspects of intermittent fasting, including recommendations around longer fasts, but lately I’ve gotten enough questions about this particular angle that I thought I’d address it. Dry fasting is going without both food and fluid. That means no coffee, no tea, no broth, and no water...
