About this episode

Why do so many people know what to eat… but still can’t follow through? In this episode, Dr. Brendan McCarthy breaks down the powerful connection between trauma, stress, and ultra-processed foods—and why willpower alone is not enough. You’ll learn how the nervous system, PTSD, and chronic stress can rewire your relationship with food, driving cravings and behaviors that feel out of your control. This isn’t about discipline. It’s about understanding the biology behind your choices. Inside this episode: How trauma changes the way you make decisions Why ultra-processed foods create temporary emotional relief The brain chemistry behind cravings (dopamine, serotonin, endocannabinoids & more) Why “just stop eating it” doesn’t work How to create real change without shame or restriction If you’ve ever felt stuck in a cycle with food, this episode will change how you see it—and give you a path forward. 📍 Protea Medical Center | Tempe, Arizona 👍 If this helped you, like, subscribe, and share with someone who needs to hear this.
