Last month the NBT team had a rare live meet-up at the Ancestral Health Symposium in Bozeman, Montana. While there, we had a chance to see many of our previous podcasts guests in person presenting their latest work. For this podcast, we passed the microphone around and shared our impressions of some of the talks we'd seen.

Along the way, we covered all kind of topics, ranging from the performance benefits of caffeine to setting up an ice bath at home. Dr. Tommy Wood shared highlights from his AHS presentation, "The Athlete's Gut," explaining why 70% of endurance athletes have a gut problem. We also caught up with friends from Virta Health, who are on a mission to reverse Type 2 Diabetes in 100 Million People.

Here's the outline of this conversation with Tommy, Megan, Clay, Zach, Josh, and Doug:
