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:BenGreenfieldLife.com/gutsolution

In this episode, you'll meet Josh Dech, a former paramedic turned Crohn's and colitis consultant who argues that all three things Western medicine says about inflammatory bowel disease are wrong: it's not genetic, not classically autoimmune, and not idiopathic. We walk the research trail from a 1988 Swedish twin study through the NOD2 gene to the genome-wide studies that mapped hundreds of risk loci and still explained only a sliver of the disease, and into the numbers that worry him most, where the West has 6% of the world's population but 60% of its bowel disease. You'll also get the practical half: his sequence to help stop the active cause first, then how he suggests opening the seven drainage pathways, why he takes a full history before ordering a single test, where peptides belong, what is really coming out of people during a parasite cleanse, and why $30,000 fecal transplants keep failing. Near the end, it turns personal and a little gross, into my own dairy problem and the biomechanics of a proper bowel movement.

From 15 Bathroom Trips A Day To A Clean Gut: Fixing Poop Issues NATURALLY  - With Josh Dech

Full show notes: BenGreenfieldLife.com/limitlessdaily

In this episode, you'll hear repeat guest Jim Kwik talk about cognitive offloading and where the line sits between using your phone as a second brain and letting your own memory go slack. We dig into the MIT study that scanned essay writers' brains and found the ChatGPT group remembered the least of what they wrote, what London cabbies' brains looked like before satellite navigation, why movement drives brain-derived neurotrophic factor (BDNF), and why racket sports and dance sit at the top of the longevity list. You'll also learn Jim's BUILD framework for using AI as a critic rather than an answer machine, how to write an affirmation your brain will not immediately reject, the white bear effect that makes "don't check your phone" the least useful instruction you can give yourself, why the 15 to 45 minutes of sleep inertia after you wake carries more weight than any other window in your day, and the four daily basics Jim ranks above every device in his house. We close with the 40 Hz gamma protocol I now use in the early afternoon, and the surprising effect it's had on how quickly I fall asleep at night. All of this comes straight out of Jim's new book, Limitless Daily, designed to give you one simple, actionable lesson each day for an entire year.

A Memory & Learning Expert Reveals His Secrets To Training Your Brain & MASTERING Your Mind, With Jim Kwik

Full show notes: BenGreenfieldLife.com/jubilee

In this episode, John Jubilee makes the case that almost everything you have been told about hydration is beside the point. His argument is that the water is not the problem, the cell is: that a membrane gets progressively harder to penetrate as you age, that your water and your supplements simply bounce off it, and that until you change the membrane itself, nothing else you do gets in. He arrived at that after a decade of doing everything right, a gallon of water a day and a thousand dollars a month in supplements, and still having high blood pressure and no cartilage left in either knee. 

You'll hear the question he asked every one of his doctors that none of them could answer, the $11,000 machine he bought in 1997 to answer it himself, and the Energized Health protocol he built out of it. You'll also get the practical layer that costs nothing: the three steps he tells everyone to start with, the balls-of-your-feet walking trick and the soleus study behind it, his case for MSM, and why he refuses to recommend alkaline, structured, or reverse osmosis water. Then it turns personal, into cellular trauma, the ACE study, and why he believes a flawless diet still leaves something unaddressed.
