Writing a book is a lot like childbirth—exhausting, and not something you rush back into the moment it’s over.

I’ve never given birth, but I have written several books—and after finishing Boundless, I wasn’t too eager to jump straight into that process again. Until recently.

There are just too many health myths wasting your time, energy, and attention—especially around supplements, cold and heat exposure, sleep, fasting, seed oils, red meat, carbohydrates, psychedelics, biohacking, and the modern obsession with living forever.

So over the coming months, I’m going to tackle these types of topics through a weekly newsletter, article, and video series, which will eventually be crafted into my next book.

If something resonates, let me know. If something falls flat, tell me. And if there’s a topic that deserves a deeper dive, point me there.

Head to https://bengreenfieldlife.com/article/newsletter-1/ for today’s article, and drop any other feedback in the comments, including topics you think I should address in the book!

Health Myths That Waste Your Time: Supplements, Seed Oils, Cold Therapy, and More

Full show notes: https://bengreenfieldlife.com/tectonpodcast

In this episode with Dr. Mike Chesne, founder of Tecton Ketones™, you'll hear how a traumatic brain injury sustained in combat led him from Army Special Forces medic to ketone biochemist, and why he eventually built what he believes is a meaningfully better exogenous ketone molecule than anything else currently on the market. We get into the real biochemical differences between ketone salts, ketone esters, and bioidentical beta-hydroxybutyrate, why the liver matters so much in how these molecules get metabolized, and a full walkthrough of Tecton's plant-based liposomal delivery system. You'll also hear about all four Tecton product formulations, the dual agonist effect ketones may have on hunger and fullness signaling, and the proposed mechanism behind why ketones may improve exercise recovery.

Dr. Mike Chesne founded Tecton after a 25-year career in United States Army Special Operations. His interest in exogenous ketones began after researching a DARPA-funded project led by Oxford University and the NIH.

The Potent Brain & Body Ketone Fuel You’ve Probably Never Heard Of: The Science Of R3HBG With Tecton’s Dr. Mike Chesne

Full show notes: https://bengreenfieldlife.com/502

In this solosode, you'll explore how to make peace with tinnitus after acoustic trauma, including the half dozen different root causes that can drive it and the specific supplements and technologies with research behind them, why cardiovascular fitness itself seems to protect your hearing as you age, and whether tattoos are actually as risky as people think, from the heavy metals hiding in colored ink to what a major 2024 study found about tattoos and lymphoma risk.

I also break down a new study showing you can get the same heat shock protein boost from heavy resistance training that you would normally only get from a sauna, why stacking a hard workout with a sauna session afterward may give you the best of both worlds, and take a closer look at a study making headlines for supposedly debunking the whole eating before bedtime rule, because the fine print tells a very different story than the headline does.

In this episode with Mazen Karnaby, founder of Zenos Health, you'll hear how a pharmacist who spent 17 years filling prescriptions behind the counter ended up building one of the more rigorously formulated supplement lines on the market. You'll hear his full story, including a melanoma diagnosis that reframed his entire approach to health, get into the formulation details behind his most talked about products, from the creatine gummies people get genuinely addicted to, to UriZen for kidney and urinary tract support, VZen for the vaginal microbiome, and BeautyZen for skin and hair, and hear about Zenos Alive and the Zenos Health Summit, a new wellness festival and conference coming to Riyadh, Saudi Arabia in 2027.

Mazen Karnaby is a US trained pharmacist and the founder of Zenos Health. After a melanoma diagnosis several years ago, his focus shifted from reactive care toward prevention and long term resilience. He co-owns Cedra Pharmacy locations across California, Texas, and New York, and built Zenos Health around science backed formulations designed to take the guesswork out of supplementation. Find him at zenoshealth.com.
