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...

Dear Mark: Protein Efficiency in Seniors, Earned Carbs, Hardgainer with Limited Time

For this week’s edition of Dear Mark, I’m answering three questions from readers. First, is the reduced protein efficiency in older adults due to inactivity, or is it something inherent to the aging process, or both? Second, how does a person know if they’ve actually “earned” any carbs? Does everyone on a keto diet earn carbs by virtue of exercising, or is there more to it? And finally, how can a hardgainer with a packed schedule all week long and limited gym time maintain what little muscle mass he’s managed to gain?

Let’s find out:

Are All Calories the Same?

As you and millions of other people embark on new dietary journeys, you’re going to hear a ton about calories.

“Calorie counting is everything.”

“If you aren’t counting calories, you won’t lose weight.”

“Just eat less calories than you expend.” For one, it’s “fewer.” Two, that’s not the whole picture.

These statements aren’t wrong exactly, but they offer an overly simplistic picture of the relationship between weight loss and calories. They ignore context. And context is everything, especially when you’re talking about calories and weight loss.

Most people (even many scientists) believe that the body composition challenge is a relatively simple equation: to lose weight you must reduce calories (either eat less or burn more), to gain weight you must add calories (eat more or burn less), and to maintain weight you keep calories constant (eat and burn identical amounts). Calories in over calories out.

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….

Dear Mark: Does Low-Carb Shorten Lifespan?

For today’s edition of Dear Mark, I’m answering a single, significant question. It concerns the latest “anti-low-carb” study claiming that we’re all killing ourselves by not eating bread. A reader wonders if the study is legit and if we should be worried about eating fewer carbs than “normal” people.

I don’t think we should be concerned, and I’ll explain why in detail. Let’s take a look and break it down.

Protein Intake While Keto: Why It Matters, How Much to Eat, and What My Intake Looks Like Now

If you ask the average person, ketosis is primarily about carb restriction and fat intake. Go on a low-carb diet, eat more fat, allow your body to burn its own reserves. Pretty straightforward. Ketones are supposed to replace glucose.

But what do we make of protein? Some keto dieters avoid it like the plague, worried anything more than a quarter pound of animal flesh will knock them back into sugar-burning purgatory. Some have even likened it to “chocolate cake.” Others eat it freely. Who’s right?

Well…
