Oprah and Yale Researcher Break Down How Weight Loss Drugs Affect the Brain

Published August 31, 2025

In this episode of The Oprah Podcast, Oprah sits down with Dr. Ania Jastreboff, an endocrinologist and associate professor at the Yale School of Medicine, to talk about the new GLP-1 medications like Ozempic, Wegovy, Mounjaro and Zepbound. Dr. Ania, who has been on the forefront of GLP-1 medication research for the past 20 years, will talk through why it is biologically difficult for some people to lose weight, maintain weight loss, and why obesity is a disease. She explains how the new GLP-1 medications work, how they can facilitate weight loss, and if they are safe. Dr. Ania answers questions from people around the country who are taking the GLP-medications and have lost a significant amount of weight. We will also share an update from Amy Kane who told her story of losing 160 pounds on weight loss medications last year on Oprah’s ABC Special: Shame, Blame and the Weight Loss Revolution.
