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...

Join Us For the FREE 2019 Keto Kickoff! (Plus, A Keto Deal You Won’t Believe…)

It’s that time of year again. People are starting to think about the new year ahead, which always goes hand in hand with resolutions aimed at improving health and fitness. I have an idea: Why not make metabolic flexibility your goal for 2019?

Metabolic flexibility refers to the ability to efficiently use different substrates for energy. Once you free yourself from carbohydrate dependency, you can enjoy sustained energy throughout the day. You can skip a meal or two—or even engage in longer fasts—comfortably. Add to this the ability to supercharge your fitness and sports performance, plus burn excess body fat without the deprivation of a traditional diet mentality.

Does Bone Broth Break a Fast?

This is a surprisingly common question.

To get it out of the way: Yes, it does. Bone broth contains calories, and true fasts do not allow calorie consumption. You eat calories, you break the fast.

However, most people aren’t fasting to be able to brag about eating no calories for X number of days. They fast for shorter (often intermittent) periods of time for specific health benefits. It’s entirely possible that bone broth “breaks a fast” but allows many of the benefits we associate with fasting to occur.

As is the problem with so many of these specific requests, there aren’t any studies addressing the specific question. The scientific community hasn’t caught up to the current trends sweeping the alternative health community. But we can isolate the most common benefits of fasting and see how bone broth—and the components therein—interact.

Holiday Eating: Considerations for Keto and Primal Types

‘Tis the season… for wondering “Seriously, what the heck am I going eat this holiday??”

I’m guessing that most Mark’s Daily Apple readers can relate to the angst that comes with trying to be a “healthy person” during the holiday season. Are you going to indulge? How much? How will you feel physically and mentally if you do? How will other people behave if you don’t?

Particularly if you’re somewhat new to a Primal lifestyle, it can be hard to figure out what will be best for you—and keto comes with a whole additional set of considerations. Compared to a more general Primal way of eating, keto requires stricter adherence to carbohydrate limitation. Moreover, it is possible to measure your ketone levels and tell objectively whether you have crossed the line (not that you have to do so). If ketosis is your goal, there is no chalking up that chocolate pecan pie to the 80/20 principle and being on your merry way.

Dear Mark: Oxidative Priority Follow-up

Last week, Craig Emmerich graced us with a great post on the oxidative priority of various dietary fuel sources, namely fats, carbohydrates, and protein.

If you haven’t had the chance to read through Craig’s post, definitely do. The visuals really drive home the point of fuel priority. Visuals appeal to me. They have a way of sticking with you, and there’s a power in recalling them when you’re making daily choices.

Today, I’m going through and answering some of the questions you folks had in the comment board.

I’ve Transformed My Body and Mind

It’s Friday, everyone! And that means another Primal Blueprint Real Life Story from a Mark’s Daily Apple reader. If you have your own success story and would like to share it with me and the Mark’s Daily Apple community please contact me here. I’ll continue to publish these each Friday as long as they keep coming in. Thank you for reading!

Hello Mark and the Primal Blueprint community! I usually don’t do stuff like this, but like many others who have discovered the Primal Blueprint path, it’s changed my life in such a positive way that it’s hard not to share. Growing up I was always athletic – trim, quick, and agile. I excelled in every physical activity I was into, without much effort. Karate, soccer, skateboarding, snowboarding, surfing, even golf came easy for me. Within my group of friends, I was the guy that was better at everything than everyone else (at least in my mind LOL). It seemed like I could maintain this level of health and physical ability forever.

Oxidative Priority: Dietary Fuels To the Body

Today’s guest post is generously offered up by Craig Emmerich, husband to—and co-author with—the queen of keto herself, Maria Emmerich. Enjoy!

When we consume macro nutrients, our bodies go through a priority for dealing with them. This priority can be very useful in understanding how our bodies work and how to leverage it for losing weight.

The body doesn’t like having an oversaturation of fuel in the blood at any time. It tightly manages the fuels to avoid dangerous situations like hyperglycemia or blood glucose that is too high. But it also manages and controls other fuels like ketones (beta hydroxybutyrate or BHB levels) and fats (free fatty acids or FFA and triglycerides) to keep them under control and not oversaturate the blood with fuel.

Why “Is It Keto?” Is the Wrong Question

Hey, folks! Today’s post is written by Dr. Lindsay Taylor. Lindsay is my co-author on The Keto Reset Instant Pot Cookbook and The Keto Reset Diet Cookbook. She also heads up our Keto Reset and Primal Endurance Facebook communities, and you might have heard her on the Primal Blueprint and Primal Endurance Podcasts. I’ve asked Lindsay if she would pop over to Mark’s Daily Apple from time to time to give us some insights from the front lines of the world of keto in addition to a few other topics. Enjoy!

Hi, everyone, thanks for having me here! Today I want to sort out one of the more common questions we get over in the Keto Reset Facebook community: “Is ____ keto?”

Fill in the blank with any type of food—beets, carrots, tomatoes, soy milk, cassava flour, you name it. It really doesn’t matter what food you insert into that blank because the answer I’m going to give is always the same:
There is no such thing as keto and non-keto food.

Now let me explain what I mean there….

Introducing The Keto Reset Diet Cookbook (Plus, an MDA Pre-Order Bonus Deal)

The Keto Reset Diet Cookbook is here! Well, almost here, but my team and I are excited to release it to the world—and especially to you, the readers of Mark’s Daily Apple. In fact, I decided to do a sneak peek today just so you’ll be the first to know.

When I published my New York Times bestseller The Keto Reset Diet in October, 2017, keto was already hot among forward-thinking folks in the health, fitness, and longevity spheres, and it was catching on in the general population as well. Over the past year, its popularity has only continued to skyrocket. While I’ve personally enjoyed watching the tide of people rejecting carbohydrate dependency eating patterns and embracing a new scope of Primal/paleo/low-carb eating strategies, I also recognize the pitfalls within the potential….

Top 9 Keto Apps

I’m not a big app guy, instead preferring to keep a loose running tally of how I’m eating, training, and living, but my understanding is that kids these days love smartphone apps. Besides, I often forget that not everyone lives and breathes this stuff. Not everyone geeks out over all the minutiae and maintains an extensive database of keto and Primal-related errata in their heads.

So today, I’m giving you a list of the top 9 keto (and keto-relevant) apps.

Keto Compared: Analyzing Keto Against Popular Diet Trends

“There can be only one.”

It’s the iconic quote from the only good Highlander movie, referring to the eternal battle immortal warriors wage across time to become the last of their kind and gain special powers over all lesser beings. I won’t say there can be only one perfect diet, but it is fun—and illustrative—to compare and contrast the different diets, not so much as a “contest” but as a method for winnowing out the differences and giving readers an idea of what might work for them.

Today, I’m going to compare the Keto Reset (my particular Primal brand of the keto diet) to other popular diet trends.

First, what is keto all about?
