Today’s podcast is about the weight-loss drug revolution—which I believe might be one of the most important stories in the world right now. Despite all the attention weight-loss drugs are receiving, it’s possible that they might soon affect the world even more than we realize as they teach us about the science of human metabolism, decision-making, and even free will. Beverly Tchang, an endocrinologist at Weill Cornell, explains how these drugs work, what they mean for people with diabetes and obesity, and how to wrap our minds around their stranger and spookier side effects.
