Dr. Valter Longo: The Science of Fasting and Longevity and the Truth No One Is Telling You

What if one of the most popular health trends in the world, fasting, is actually being done wrong by millions of people? In this powerful and deeply grounded conversation, Darin sits down with world-renowned longevity expert Dr. Valter Longo to cut through the noise surrounding fasting, dieting, and modern health trends. From the dangers of prolonged fasting and skipping breakfast to the science behind the Fasting Mimicking Diet, this episode delivers a reality check rooted in decades of clinical research, not social media hype. They explore the intersection of longevity, cancer, metabolism, and modern lifestyle, unpacking why extreme protocols fail, why simplicity wins, and why aligning with your biology is the true key to a long, disease-free life.   BREAKDOWN What You’ll Learn in This Episode: 00:00:00 – Opening: SuperLife mission and framing the conversation 00:00:32 – Sponsor: Therasage infrared sauna and heat therapy
