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.

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.

Sheet Pan Dinners: Three Meals In 90 Minutes

Putting dinner on the table just got easier with this meal prep plan that bangs out three dinners at once. All the mix-and-match ingredients you need for three different meals are cooked on single sheet pans, making cleanup easy, too.

The cooked ingredients are simply seasoned with salt and pepper for maximum versatility. Add more varied flavors when you dish up by incorporating the suggested herbs, spices, dressings, and garnishes.

Each meal provides 4 servings. The food can be served at room temperature, reheated in a microwave, or reheated by sautéing the ingredients briefly in a pan with oil.

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….

Dear Mark: Omega-6 Deficiency and Saw Palmetto

For today’s edition of Dear Mark, I’m answering two questions from readers. First, is it possible to become deficient in omega-6 fats as an adult? What would that even look like, and is there anything that might make omega-6 more important?

Second is a question related to last week’s feature on prostate health. Is saw palmetto an effective supplement for prostate issues? It depends on the issue.

Let’s go:
