#312 - Is Moderate Drinking Actually Healthy? | Dr. Tim Naimi & Mike Haney
Dr. Tim Naimi, a physician and leading alcohol epidemiologist, examines the tangled science of drinking and health. He explores alcohol’s links to cancer and heart disease, why moderate drinking once appeared protective, and how “sick quitter” bias, confounding, industry influence, and politics shaped the headlines. He also discusses falling alcohol use and the possible role of GLP-1 drugs.

#311 - Can Your Blood Predict Your Future Health? | Dr. Tony Wyss-Coray & Mike Haney
Dr. Tony Wyss-Coray, Stanford neuroscientist and brain-aging researcher, explores how a single blood sample can measure thousands of proteins. He discusses young-blood experiments, organ-specific aging clocks, biological waves of aging, and how heart and brain age may forecast future disease. He also looks at cell-level diagnostics and a future “health compass” for tracking personalized interventions.

#310 - Can We Measure Aging Well Enough to Treat It? | Dr. Nir Barzilai & Mike Haney
Dr. Nir Barzilai, a physician-scientist and leading geroscience researcher, explores how centenarians stay healthy longer, why aging drives many diseases, and whether it should be treated directly. He discusses aging hallmarks, metformin and other potential gerotherapeutics, the stalled TAME trial, and FAST’s search for biomarkers that reveal whether treatments are truly changing aging biology.

#309 - What AI Sees That Doctors Can’t | Dr. Ziad Obermeyer & Mike Haney
Dr. Ziad Obermeyer, an emergency physician and Berkeley machine-learning researcher, explores AI’s untapped role in medicine. They discuss biased algorithms, an ECG model that detected hidden sudden-cardiac-death risk, and how patient outcomes can teach machines what doctors miss. The conversation also examines healthcare’s data bottleneck, smarter wearables, and a future of continuous monitoring with fewer unnecessary tests.

#308 - Why Some Foods Are So Hard to Stop Eating | Dr. Dana Small & Mike Haney
Dr. Dana Small, a neurologist and psychologist who studies how the brain and body learn about food, explains why some foods trigger persistent cravings. She talks about how taste vs flavor differ, how post-ingestive nutrient signals teach the brain, why fat+carb combos hit especially hard, and how treatments like GLP-1s and behavioral relearning can alter wanting without killing pleasure.

#307 - It Took Months to Interpret His Genome. Claude Did It in 30 Minutes. | Dr. Euan Ashley + Mike Haney
Dr. Euan Ashley, Stanford medicine chair and author who led one of the first clinical genome interpretations. He recounts early genome interpretation and how AI replicated months of work in minutes. He explores the rise of multi-omics, wearables, and the need for better reference datasets. He discusses practical barriers to scaling personalized medicine and the promise and pitfalls of AI in healthcare.

#306 - Does Intermittent Fasting Actually Work? | Dr. Courtney Peterson & Mike Haney
Dr. Courtney Peterson, an Associate Professor in Nutrition Sciences with a PhD in physics who runs tightly controlled trials on meal timing. She digs into time-restricted eating, why early-day eating can lower blood pressure and improve insulin sensitivity, how circadian rhythms shape results, and why individual schedules like shift work change outcomes.

#305 - What You Can Learn from Measuring Everything | Dr. Michael Snyder & Mike Haney
Dr. Michael Snyder, Stanford geneticist pioneering continuous multi-omics and wearable measurement. He recounts building long-term personal baselines, how wearables and whole-body MRIs flag trouble before symptoms, discovering a unique form of diabetes in himself, and which continuous biomarkers and monitoring strategies could reshape prevention and personalized care.

#304 - Did Low-Fat Diets Drive the Obesity Epidemic? | Dr. Arne Astrup & Mike Haney
Dr. Arne Astrup, physician and nutrition researcher who helped ban industrial trans fats, unpacks the history and missteps of the low-fat era. He traces how fat fear reshaped food, explains why fat alone did not drive obesity, and explores satiety, food matrices, carbohydrate tolerance, and practical whole-food guidance in place of nutrient fixation.

#303 - Why Healthcare Needs an Intelligence Layer | Dr. Robert Wachter & Mike Haney
Dr. Robert Wachter, Chair of Medicine at UCSF and author on digital health, discusses healthcare's messy digital shift and AI's next act. He explores why records and continuous sensors alone will not fix care. Short takes cover clinician overload, the need for an intelligence layer to sort signals, AI changing patient knowledge, and the safety and integration challenges ahead.
