The Knowledge Project with Shane Parrish
Dr. Giulia Enders has changed the way millions of people think about the human body.
As a physician, microbiome researcher, and bestselling author, she has spent years studying the surprising role the gut plays in everything from digestion and immunity to mood, sleep, metabolism, and long-term health.
In this conversation, Giulia explains how your gut shapes your health, how stress quietly damages it, what ultra-processed foods are doing to you, and what your body’s been trying to tell you all along.
This episode is packed with practical advice you can use right away. You’ll understand your body better and leave with a simple framework for improving your health, without complicated diets, expensive supplements, or extreme interventions.
If you’ve ever wondered why you feel the way you do, this conversation is a great place to start.
