Today I’m overjoyed to announce the release of my latest, greatest, and certainly broadest attempt at a comprehensive plan to live long and live awesome: Keto For Life. The book’s official on-sale date is December 31, and—as tradition goes on Mark’s Daily Apple—I’m offering an incredible group of free bonus materials as a pre-order gift. Here’s a link where you can access your favorite online retailers to order, but know you can also visit your favorite brick and mortar bookstore to pre-order, too.
Folks, I know many of you have been here with me and the MDA community for enough years to remember how this all began with the Primal Blueprint. It’s been such an awesome journey—and one that keeps evolving in incredible ways. I genuinely feel like it’s all been leading toward this one. I’ve poured my personal experimentation and hard-gained insight into every book I’ve written, but this one feels, well, like a whole new level of inquiry and practice. Keto has kicked off not just a dietary trend the last few years but truly a whole new realm of scientific research. I’ve been knee-deep in it in writing this book, and I’ve not only delved into these revolutionary findings but have also taken the integration of keto science and Primal lifestyle principles to an entire new level. Let me tell you about it….
There was a time when food tracking was treated like a given, a necessary tool for anyone wanting to lose weight or better their health. Thankfully, there’s more nuance to that conversation now. The fact is, tracking your food can be a useful exercise for gaining more insight into what you’re putting in your body. It can also be a tedious endeavor that sucks all the joy out of eating.
If you’re going to invest the time—and it can be quite time-consuming if you include any variety in your diet—let’s make sure it’s not a waste.
When I did my first earnest attempt at a keto diet a few years ago, one of the benefits I quickly noticed was improved wakefulness and energy during the day. I chalked this up to sleeping better on keto.
It turns out that I might have been one of the lucky ones. While plenty of people report improved sleep, a fair number also complain of insomnia, sleep disruptions (waking frequently during the night), and generally poor sleep once they go keto.
Can a keto diet really impact sleep quality? What might be the mechanism behind a correlation? And how does one work around any potential effect?
For today’s edition of Dear Mark, I’m answering five questions taken from this Twitter thread. First, does collagen offer anything special above and beyond glycine? Second, what’s the relationship between keto and gallstones? Third, do I recommend eating raw liver, and why or why not? Fourth, why does one reader’s scalp itch when eating stevia? And finally, what’s the best way to lose fat and gain muscle at the same time?
The ketogenic diet has exploded in popularity over the last few years. Hordes of people are using it to lose body fat, overcome metabolic diseases, improve their endurance performance, attain steady energy levels, make their brain work better, and control seizures. And increasing numbers of researchers and personal experimenters are even exploring the utility of ketogenic diets in preventing and/or treating cancer. After all, back in the early part of the 20th century, Warburg discovered an important characteristic of most cancer cells: they generate their energy by burning glucose. If a particular cancer loves glucose, what happens if you reduce its presence in your body and start burning fat and ketones instead?
It’s taken a while, but the research community is finally beginning to take a few swings at this and similar questions.
“Has Mark given up Primal?” I get this question all the time, and I’m not surprised. Over the past few years, I’ve really focused on exploring the utility, applications, and ins and outs of the ketogenic diet. Why?
I’m still Primal and have been for over a decade. That won’t ever change. And you can go Primal—drop industrial seed oils, added sugar, and grains—and be perfectly fine. Better than 95%. You’ll lose body fat, gain energy and performance, and reduce your risk of degenerative disease. It will always be the foundation of my eating—and living. But I see (and have experienced) keto as a boost, an enhancement, a Reset. A return. Today I’m answering some questions around this idea with a new video.
When I say “hack” or “biohack,” what does that call to mind for you? Taking 20 supplements per day, shining special lights into your ears, stem cell injections? Simpler things like wearing blue light blocking glasses or turning your shower to cold for 30 seconds?
The term has become ubiquitous in modern parlance, to the point where its meaning has become blurred. On the one hand, hacking can be about optimizing—taking your health and fitness to the next level once you have the basics dialed in, or adopting strategies aimed at living well over 100. On the other hand, a hack can also be a shortcut or trick designed to reap certain benefits without putting in the usual work. (Whether that’s a clever maneuver or a form of “cheating” depends on the context and whom you ask.)
For today’s edition of Dear Mark, I’m answering a few questions from recent comment boards. First, with all the scary tick-related news coming out lately, are there any non-toxic tick repellents that actually work? Are there essential oils that repel and/or kill ticks? Is there a safer way to use insecticides? Next, were the people in the Mediterranean keto study actually eating a kilo of fish on their fish days? And is the wine an important part of the Mediterranean diet? Is the wine therapeutic or just for pleasure?
Let’s find out:
As I’ve written before, although most people’s lipid numbers improve across the board, some people get interesting cholesterol responses to Primal ketogenic diets. LDL skyrockets, even LDL particle number. The jury’s out on whether or not they indicate negative health concerns or if keto dieters are a special breed that hasn’t received enough study. (There may be a few genetic profiles, such as APOE4 carriers, that react differently to certain dietary inputs.) Either way some people just want their cholesterol numbers to look good in a conventional way. These days, whenever I run into someone in the real world with these or similar concerns, I tell them to try “Mediterranean keto.”
What is that, anyway?
I love dairy. As a man of primarily Northern European descent, my ancestors have been consuming the stuff for thousands of years. It doesn’t give me any issues. You won’t find me chugging tall glasses of straight milk these days, but I’m a big believer in cream, cheese, yogurt, and kefir. Very nutrient-dense food if you can handle it. Lactase persistence? I practically have lactase insistence.
My favorable response to dairy makes keto especially easy. High-fat and fermented dairy is high in nutrients and low in digestible carbs (the bacteria consume most of the lactose). Cheese, cream, kefir, and yogurt all happen to be the most nutritious forms of dairy and the most keto-friendly. Many others getting into keto lean heavily on dairy. It just makes keto easier, especially if you’ve grown up eating dairy.
But globally my reaction to dairy is pretty rare, and that changes the keto landscape for most people.
