Meet Mark

Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...

12 Favorite Keto Blogs

With the explosion of keto, there’s an ever growing constant stream of new information about the significant benefits, supposed risks, and varying “rules” for how to adopt a keto diet. As with most things, it’s easy to get sucked into information overload. (And that doesn’t even take into account the hype that unfortunately gets distributed like wildfire around the Internet.) You want sources you can count on for facts, reason, and utility. While there are many resources out there, here are twelve sites I enjoy for intelligent commentary, sound science, and useful ideas. They may not be the biggest, but over time they’ve become my personal favorites.

The Definitive Guide To What Breaks a Fast

One of the most common questions I get is “Does [x] break a fast?”

What they’re really inquiring about is: “Does this interfere with, negate, or nullify the benefits of fasting?”

These benefits include:

Ketosis: Fasting is the quickest way to get into ketosis, an metabolic state characterized by increasing fat burning, fat adaptation, and—in some people—improved cognitive function.

Fat Loss: When you’re fasting, you’re not eating, and not eating is the best way to force your body to burn the fat it already possesses. Fasting also means no additional calories are coming in, and many people find that fasting is a great way to control their calorie intake.

Autophagy: Autophagy, or “self-eating,” is the process by which our cells prune damaged components, maintain proper function, and keep aging at bay. Fasting triggers autophagy. Breaking the fast will stop autophagy.

Let’s go through the most popular queries one by one and figure out how each one affects an intermittent fast. (For questions about what supplements break a fast, check out my post, “What Breaks a Fast: Supplements Edition.”)

Dear Mark: Antibiotic Recovery, Sprinting on Keto, Preparing for Bad Sleep

For today’s edition of Dear Mark, I’m answering three questions. First up, what can a person do to help their gut recover its barrier function after too many antibiotics? Are there any foods, supplements, or dietary strategies? Second, what can explain rapid fatigue during sprint sessions on a keto diet? Is this simply part of the deal, or are there modifications you can make? And finally, what do I do when I know I’m going to get a bad night’s sleep?

Let’s go:

How I Take My Coffee (+ Ultimate Coffee Giveaway)

I’ve got another awesome success story coming up later this morning, but first…coffee.

As I said on Friday, I take my coffee very seriously. So, no April Fool’s here. Just a great giveaway for any coffee lover out there…

I’m not a breakfast eater as many of you know. As a result, my morning coffee is important to me. It’s a sensory experience I enjoy as well as a ritual that kicks off my day. Sure, the caffeine offers a little pick-me-up, but I make it count nutritionally with a collagen boost, too.

19 Keto Soups

Thanks to the good folks at Paleohacks for today’s recipe.

There’s nothing quite like cozying up on the couch with a warm bowl of rich and hearty soup. Unfortunately, hearty soup recipes often rely on high-carb ingredients like potatoes, rice, and noodles to achieve comfort food status.

Luckily, we know tons of Paleo-friendly soup recipes that fuel your body and nourish your belly—all while keeping you in ketosis. Think fat bomb hamburger soup loaded with veggies and beef, or a velvety, dairy-free celeriac soup with chorizo, sage crisps and walnuts. If you’re craving takeout, there’s keto-friendly hot and sour soup, or if you need something that takes hardly any effort, we have a go-to chipotle chicken soup you can make right in a slow cooker. Whatever you crave, there’s a healthy soup to enjoy. Check out these 23 keto-friendly snacks to keep you going between meals.

The Definitive Guide To Autophagy (and 7 Ways To Induce It)

Biological systems are self-maintaining. They have to be. We don’t have maintenance workers, mechanics, troubleshooters that can “take a look inside” and make sure everything’s running smoothly. Doctors perform a kind of biological maintenance, but even they are working blind from the outside.

No, for life to sustain itself, it has to perform automatic maintenance work on its cells, tissues, organs, and biological processes. One of the most important types of biological maintenance is a process called autophagy.

Autophagy: the word comes from the Greek for “self-eating,” and that’s a very accurate description: Autophagy is when a cell consumes the parts of itself that are damaged or malfunctioning. Lysosomes—members of the innate immune system that also degrade pathogens—degrade the damaged cellular material, making it available for energy and other metabolites.  It’s cellular pruning, and it’s an important part of staving off the worst parts of the aging process.
