Dr. Zoë Harcombe is an intellectual powerhouse—a Cambridge graduate with degrees in economics and mathematics, a long-standing member of Mensa, and a fearless truth-seeker. In this episode, she brings her sharp insight and deep curiosity to a wide-ranging conversation that spans nutrition, public health, and the increasingly complex issue of free speech.

Before dedicating herself to the world of diet and health in 2008, Zoë built a high-flying career in the corporate world. She held international roles in management consulting, manufacturing, and marketing across major global industries—from FMCG to telecoms—before focusing on Human Resources. She’s worked on the inside of both Big Food (Mars Inc.) and Big Pharma (GSK), giving her a rare, insider’s perspective on how these powerful sectors operate. At the height of her corporate journey, she served as Vice President of HR for Europe, the Middle East, and Africa.
