Dr. Ravi Kumar is a board-certified neurosurgeon who left the operating room to explore the questions that matter most about your health.
Listen to the PodcastEvery week, I cut through the noise of health headlines and marketing claims to bring you what the research actually says. No dogma, no agenda, just an honest look at the science that shapes how you live, heal, and thrive.
Most people have never heard of reactive hypoglycemia, and neither have a lot of physicians, yet it may affect up to half the population and it is one of the earliest warning signs on the road to prediabetes and diabetes. Dr. Ravi Kumar sits down with Dr. Keith Berkowitz, who worked alongside Dr. Robert Atkins in the late 1990s and carried that whole way of practicing medicine forward after Atkins died. They unpack what reactive hypoglycemia actually is, why a blood sugar crash a few hours after eating leaves you tired, foggy, anxious, and hangry, why it is the cortisol response and not the low glucose that produces the symptoms, and how insulin resistance builds for 20 years before a standard lab ever looks abnormal. Along the way: the low fat era, the sugar industry's role in villainizing fat and eggs, the gut microbiome, continuous glucose monitors, and why the tools to catch this early finally exist.

Researchers screened more than 5,000 blood proteins in a cohort followed for nearly 20 years and built a 19-protein panel that estimates the timing of ALS onset in people who carry a high-risk gene.
The Senate HELP Committee voted 12-10 to advance the Childhood Diabetes Reduction Act, which would put warning labels on ultra-processed foods and ban junk food ads aimed at children.
★★★★★"So glad I found this podcast. Dr. Kumar doesn't want you to just mask symptoms, he wants you to understand root causes and help you truly heal. He is the best of both worlds - he shares a wealth of modern medical knowledge, but also empowers the listeners to take personal responsibility for their health."
