From board-certified plastic surgeon to pioneering regenerative medicine, Dr. Eric Weiss joins me to unpack how a deeply personal journey with his autistic son Marston led him to the frontier of stem cell–based therapies. We dive into the science behind glial cell inflammation, why umbilical cord stem cells are so powerful, and how chronic inflammation may sit at the center of both autism and aging. If you’ve ever wondered where fasting, exercise, NAD/NMN, and mitochondrial health actually intersect with real-world medicine, this episode goes straight into the cellular trenches.
