Ep171 "Why Do Some Urges Feel Irresistible?" with Paige Gordon
Summary
David Eagleman explores the biological underpinnings of eating disorders with author and former model Paige Gordon, who shares her decades-long struggle with bulimia. They discuss how genetic variants and dysregulated GLP-1 receptors can create intense "food noise," making willpower an unfair standard for those with different neurobiology. Gordon’s experience with low-dose GLP-1 medication, which quieted her intrusive thoughts, highlights the potential for precision medicine to replace shame with curiosity. The episode argues that understanding the brain’s hidden machinery fosters deeper co…
