In this episode of The Feldman Protocol, can a practicing family physician's personal health crisis reshape the dietary advice he gives to thousands of patients? Ken Berry (MD) makes the case for low-carbohydrate approaches in managing metabolic conditions, shares his path from rural Tennessee to family medicine, discusses founding the American Diabetes Society as an alternative institution, explores the debate around long-term ketosis and fasting insulin, and joins Dave and audience members in examining how to rebuild trust in medical and scientific institutions.
