☠️ The Dangerous Rise of Bro Science in Jiu-Jitsu

In this episode of Fighting Matters, Steve Kwan and Stephan Kesting are joined by scientist and author Kristi Charish to investigate how Jiu-Jitsu became a hotbed for pseudoscience, supplement scams, and influencer grifts.

We explore how a culture of male insecurity and anti-intellectualism has opened the floodgates to misinformation—fueled by algorithm-chasing gurus and podcast personalities more interested in profit than truth. From testosterone fads and supplement sponsors to sunning your testicles (yes, really), we unpack the deep societal forces that make grapplers uniquely vulnerable to snake oil.

If you’ve ever been told that breathing through one nostril will double your growth hormone, this episode is for you.
