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...

The MDA Ultimate Guide to the Keto Diet

Welcome to Mark’s Daily Apple!

I know Google searches for keto and “ketogenic diet” are at an all-time high. (Perhaps that’s how you got here today!) And there’s good reason for their growing popularity….

Mounting research suggests that keto could represent one of the greatest nutritional breakthroughs of our time—and that it may be the most effective weight loss strategy ever.

For people who have tried to free themselves from the disastrous impacts of carbohydrate dependency, keto offers a uniquely successful and fully sustainable answer.

Are you interested in rapid and sustained weight loss? Would you like to experience more physical energy and mental clarity every day? Are you ready to reprogram your metabolism, claim better health, and boost your body’s natural fat-burning abilities?

Then you’ve come to the right place.

I’m building this comprehensive online guide to share the science behind keto success, the secrets to becoming fat-adapted, and helpful resources as well as dozens of delicious recipes for planning your individual keto choices. Within these pages, you’ll find I distill the latest medical research and offer honest analysis of popular (and less common but effective) keto strategies.

You’ll find here everything you need to get started today, but I also encourage you to check back often—because I’ll be adding more resources, recipes, graphics, success stories, and tips every single week. In fact, shoot me a line with any questions or ideas you might have.

My aim at Mark’s Daily Apple has always been to provide cutting edge information for achieving optimal health and sustained well-being—no matter what your current age, weight, fitness or goals.

Looking forward to sharing the keto journey,

— Mark Sisson, author of the New York Times Bestseller, The Keto Reset Diet

What Is the Ketogenic Diet?

The ketogenic diet is a diet that, by way of macronutrient balance (high fat, moderate protein, and very low carbohydrate in comparison to the Standard American Diet) induces the body to burn ketones and fat in addition to glucose for energy.

Lucky for us, this flexibility is entirely natural, safe, and beneficial. Contemporary eating patterns, much to our detriment, keep us reliant on glucose, but that’s not the way we’re designed to live.

Keto is a state of metabolic efficiency.

This means you move beyond being dependent on regular carbohydrate intake and into the ability to burn stored body fat and natural ketones (hence the name ketosis) for physical energy, stable mood, and mental focus.

Many of us have unfortunately been told over the years that the body relies on glucose for energy. That simply isn’t the case.

Glucose is one fuel, true. But the body can also burn its own fat stores as well as ketones, which the liver produces as a by-product of fat metabolism. Ketones are a natural source of caloric energy just as glucose is. But there’s a key difference here. The body’s sustained use of ketones and fat (which go hand in hand) doesn’t impose the same inflammatory and oxidative burden as we experience when we’re continually carb (glucose) dependent, which is one reason why keto confers so many benefits to overall health.

The technical meaning of ketosis is the metabolic state in which your body accumulates ketones faster than they’re being burned.

When we’re fat-adapted (a.k.a. keto-adapted), we’re able to enjoy the benefits of burning fat and ketones as first-rung fuel sources.

However, when we’re in ketosis without being keto-adapted (e.g. on a crash diet), we’re likely to excrete these ketones in our urine and breath instead of burning them for energy, which means we’re still left carb-dependent.

To set up the body for the benefits of keto-adaptation, we consume a healthy, rather than restrictive, amount of calories within the following macronutrient profile:

  • 65-75% healthy fats 
  • 15-25% protein
  • 5-10% carbohydrates

The carb-heavy Standard American Diet is an evolutionary aberration. The constant drip of glucose into our blood is a modern luxury (or, more to the point physiologically-speaking, a modern burden). For most of human history, if we wanted carbs, we had to climb a tree and extricate a bee’s nest, spend hours digging tubers, or wait around for the wild fruit to ripen.

We are designed for periods of low food availability, and, especially, low glucose availability. In short, we’re wired to favor fat and ketone burning.

Plus, humans are remarkably good at slipping into ketosis. Whereas for most other animals ketosis is difficult to achieve, a human will be mildly ketotic just waking up from a full night’s sleep. Heck, breastfed babies spend much of their time in ketosis despite drinking nutritionally balanced milk from their mothers. We’re clearly meant to produce and utilize ketones from time to time, and it’s safe to assume that mimicking this ancestral milieu provides adaptive benefits.
