Dr. Brendan McCarthy explores the connection between trauma, stress, and dietary choices, emphasizing that willpower alone is insufficient for overcoming food-related challenges.

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.
