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.
A Global Burden of Disease analysis found annual US alcohol-attributable cancer deaths climbed from 11,361 to 23,126 between 1990 and 2023, with colorectal cancer overtaking liver cancer as the top alcohol-linked cancer death in adults under 55.
A Florida International University study tested Apple, Garmin, Samsung, and Fitbit watches against lab-grade metabolic equipment and found they read high, with the biggest errors in people carrying more body fat.
A national records study of more than 300 million patients found weight-loss drug prescribing in grade-schoolers climbing fast from a very low starting point, with almost all recipients already carrying severe obesity and a second illness.
A genetic analysis of more than 205,000 men found that inherited GLP-1 receptor activity tracks with male pattern hair loss, but no one in the study was taking Ozempic, Wegovy or Zepbound.
Four national medical societies published their own fall and winter shot recommendations on September 2, alongside three JAMA evidence reviews, after the CDC's vaccine advisory committee was dismantled and left in legal limbo.
A Czech trial of 558 patients found that threading a catheter into a lung clot and dripping in a clot-dissolving drug beat blood thinners alone, without the bleeding penalty that sank earlier attempts.
What if some of the most severe mental illness is, in part, a brain energy problem? Dr. Ravi Kumar sits down with Dr. Matt Bernstein, a traditionally trained psychiatrist who now runs Accord, an immersive metabolic psychiatry program outside Boston, to unpack why brain regions like the hypothalamus, hippocampus, and amygdala can starve for fuel while glucose is plentiful everywhere else, and why ketones bypass that insulin gate entirely. They walk through the Stanford pilot in which every fully adherent patient with schizophrenia or bipolar disorder reached remission, a French inpatient series with effect sizes far beyond what antidepressants typically produce, and the clear limits of both, since neither had a control group. They also cover ketogenic ratios, why Bernstein keeps protein high, the three month commitment it takes to know if it is working, and why none of it works without sleep, sunlight, movement, and medical supervision.

Dr. Ravi Kumar is a board-certified neurosurgeon and assistant professor of neurosurgery at the University of North Carolina. After years in the operating room, a transformative sabbatical in India changed how he saw medicine forever.
Now, through The Dr. Kumar Discovery, he explores the intersection of modern science, traditional wisdom, and the questions most doctors never think to ask.

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."
