There has been a fundamental shift in understanding metabolic health and chronic disease, particularly Type 2 diabetes, challenging long-standing dietary dogma by emphasizing that insulin resistance is largely driven by overconsumption of refined carbohydrates, not dietary fat or red meat. While highlighting the success of carbohydrate restriction and ketogenic approaches, nutrition is being seen as a powerful tool for reversing diabetes—often more effective and sustainable than conventional medication. The implications are far-reaching, not only for individual health outcomes, but also for reshaping public health strategies in addressing today’s chronic disease epidemic.

In this episode, I speak with Gary Taubes, Sami Inkinen, and Dr. Greeshma Shetty about an approach to treating Type 2 Diabetes that works. I also discuss how red meat is not to blame, but we should be looking at high sugar and starch diets.

Gary Taubes is an award-winning science and health journalist, and co-founder and director of the Nutrition Science Initiative (NuSI). He is the author of The Case Against Sugar, Why We Get Fat, Good Calories, Bad Calories, and, most recently, The Case for Keto.

He lives in Oakland, CA.
