Author: Sean Kim July 28, 2026 Duration: 1:11:31

Dr. Robert Lustig is a neuroendocrinologist, professor emeritus of pediatrics at UCSF, and bestselling author of Fat Chance, The Hacking of the American Mind, and Metabolical who has spent 40+ years studying metabolism and the role of sugar in chronic disease. In this conversation, he breaks down the real root of modern burnout, why fructose acts as a poison without its fiber "antidote," and the science of how sugar hijacks the same reward circuitry as any other addiction.
