Dear Mark: Synthetic Peptides

For today’s edition of Dear Mark, I’m answering one question from a reader. It’s all about synthetic peptides, small chains of amino acids with potentially huge effects on your health and physiological function. In most cases, these synthetic peptides are based on naturally-occurring compounds found in the human body. Scientists isolate the “active component” of the compound and whip it up in a lab by stringing together the right amino acids. Many of these peptides are available for purchase online, strictly “for research purposes.” But people are using them.

Are these safe for humans? Are they effective?

What We Get Wrong About Childhood Obesity

Weight Watchers (recently rebranded to WW) put out an app for kids and teens who want to lose weight a few months ago. It’s called Kurbo, and it assigns “traffic light” color codes to different foods. Green foods like fruits and vegetables can be eaten freely, yellow foods like low-fat dairy, lean meat, and bread can be eaten in moderation, and red foods like full-fat dairy and sweets should be eaten sparingly or “planned for.” Kids under 13 need to sign up with a parent, while older kids can sign up on their own. Online coaching is available for an extra fee. Users are urged to track their food intake and body weight, even if they choose a goal like “Have more energy.”

Critics hit back. The Atlantic claimed that using apps like Kurbo won’t make a difference for the kids who need it most—those living in “food deserts,” those exposed to junk food marketing, those whose parents can’t afford healthy food and haven’t the time to fix healthy meals. Outside Online warned against the potential for Kurbo to create unhealthy fixations on food and “clean eating” in kids, setting the stage for eating disorders that can increase the risk of mortality, depression, and anxiety later in life. They called for an overhaul of “food policy” instead.

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.

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….

I have been doing Obstacle Course races since 2013 and tried to keep myself active in training, but my diet was never really in alignment. I was the poster child to demonstrate that physical fitness is not the driving component in body composition in health—diet is. My heaviest was 188 lbs (5’9”), and I was always disappointed to see my race photos showing a fat belly and zero muscle definition.

13 Holiday Side Dishes (That Aren’t Potatoes)

While there’s nothing particularly wrong with potatoes (in fact, we happen to love this recipe for scalloped potatoes), not everyone in the Primal—let alone keto—camp wants to serve potatoes at the holiday. They’re a technically Primal choice, but they’re decidedly high in carbs and not as high in nutrients as other options. Primal and Primal-keto eating shouldn’t be about deprivation—just thoughtful decision-making on what’s a good choice for you when it comes to holiday eating. Today we’ve got 13 delicious side dish recipes that stay true to the richness and flavors of traditional holiday cooking. Which ones will you be serving?
