Big Things I’ve Changed My Mind About: Keto, Carnivore, Cryotherapy, Statins, THC, Sleep Hygiene, Minimal Effective Dose Of Exercise & More!

As I've been researching and writing Boundless 2.0, I've found myself reevaluating many of the health and fitness strategies that I previously endorsed.In this episode, prepare to have your perspective challenged as I discuss some of the significant shifts in thinking I've undergone while exploring the latest science and experimenting with biohacking.

To kick off the show, I discuss one of the biggest areas where I've updated my thinking — the ketogenic diet. While I was previously gung-ho about strict therapeutic ketosis for all sorts of applications, I now have a more nuanced view that involves limiting carbohydrates during the day for enhanced focus and consuming 200 to 300g in the evening to support better sleep and hormonal balance. Additionally, I've moved away from a saturated fat-heavy keto diet to a Mediterranean-style approach with foods like avocados, olives, oily fish, and olive oil.

When it comes to exercise, I used to be that guy who obsessively crushed two-a-day workout sessions. But the more I dig into the research, the more I've come to understand the importance of staying within the "Goldilocks Zone" — enough training to accrue benefits, but not so much that you risk overtraining.

Another controversial mind shift I've experienced is around statins, which was prompted by my advanced cardiac screening. My Cleerly test revealed plaque buildup, leading me to start a PCSK9 inhibitor and a daily dose of rosuvastatin and acetamide. While I still don't think these drugs should be blindly taken, in some cases the benefits can outweigh the risks if properly monitored.

My view on cold exposure has also slightly changed after digging into research. I used to be all about long ice baths and open-water cold swims, but now I've shifted to shorter, more frequent cold exposures. (You'll hear multiple times throughout this show that optimizing your body is all about finding the right balance and avoiding excessive stress.)

This show also covers topics like the hidden benefits of aspirin, ginger, and yes... even "dick pills." Plus, you'll gain insights into sleep hacking, why I'm taking a more discerning stance on cannabis, and the dangers of extreme biohacking.
