Meet Mark

Does Coffee Break an Intermittent Fast?

This has got to be one of the most frequent questions I see:

“Does coffee break a fast?”

Let’s answer.

To begin with, I’ll make the case that you shouldn’t worry too much about this stuff. That you’re even willing and able to go without a meal or snack for 12-24 hours places you in rarefied company. That’s 95th percentile stuff. You’re ahead of the game simply by being open to the idea of not eating every hour. Take heart in that. Some coffee with cream midway through doesn’t take away from what you’re accomplishing.

But I know you guys, and I know you love the minutiae. I know it because I love it, too. It’s fun, even if it gets us into trouble sometimes. So let’s dig right in.

Dear Mark: Phones in Bedrooms, Antidepressants, Pastured Egg Omega-6 Content

For today’s edition of Dear Mark, I’m answering three questions from readers. I’ve come down hard against phones in bedrooms in the past. Is there a “good way” to use your phone in the bedroom? Reader Kathy offered some good reasons for keeping a phone there; what do I think? Next, HealthyHombre laments having to take antidepressants (but he shouldn’t lament). And finally, I cover the differences in omega-6 between pastured eggs and conventional eggs.

A Day In the Life Of Keto

I get the question all the time: “So, what does a regular day of eating look like for you?”—particularly since I went keto. I get asked when I typically start eating and how I schedule my workouts around fasting periods? What do my meals themselves look like? Do I ever snack? Today I’m answering all of these—and sharing more about my own personal approach to ketogenic living.

Dear Mark: PUFA Confusion, Mushroom Coffee, Swiss Water Process, and Timing the Fast

For today’s edition of Dear Mark, I’m answering four questions from readers. First, should someone homozygous for the FADS variant that increases PUFA conversion eat less or more PUFA? Next, what’s the deal with all the mushroom coffees out on the market? Are they actually beneficial? Third, when looking for a healthy decaf coffee, what should you watch for? And finally, how should a breakfast skipper/intermittent faster deal with increased morning hunger caused by morning workouts?

Let’s find out:

14 Ways to Make Coffee Healthier

According to the stats, more than 80% of American adults use coffee to get going in the morning. Increasingly, we’re getting collectively pickier about what we drink, too. A report released this year by the National Coffee Association found that, for the first time in 67 years, more than half of all coffee consumed daily was classified as “gourmet.” 

But let’s be honest. There’s a lot of junk in that category—syrups and whipped toppings, soy milk and sugar galore. It’s a damned shame because coffee can offer big health benefits when done right. When done even better? Well, let’s take a look.

How Ancestry Might Inform Your Fat Choices

One of the more exciting developments over the past few years has been the explosion in population genetics research. People are a diverse lot, and even though we’re all people who essentially want the same things out of life (and we’re working with the same basic machinery), there’s a lot of wiggle room. It’s not just information for curiosity’s sake. The information researchers are uncovering about human ancestry can have real ramifications for how said humans should eat.

A couple years ago, I wrote a post laying out a few guidelines for using your personal ancestry to inform your diet. Today, I’m going to talk about another one: polyunsaturated fat metabolism.
