#318 - How Sleep Changes What and How Much You Eat | Dr. Marie-Pierre St-Onge & Mike Haney
Dr. Marie-Pierre St-Onge, a Columbia professor and sleep-nutrition researcher, explores the two-way relationship between sleep and eating with Mike Haney. They discuss chronic sleep debt, appetite hormones, extra calorie intake, food cravings, meal timing, tryptophan and “sleep foods,” plant-rich diets, and whether wearable sleep scores deserve your attention.

#317 - What It Takes to Build Medical AI Doctors Will Trust | Dr. Suchi Saria & Mike Haney
Dr. Suchi Saria, a Johns Hopkins AI researcher and Bayesian Health founder, shares the decade-long journey from sepsis prediction research to medical AI used in hospitals. They explore real-time monitoring, causal reasoning, uncertainty, alert fatigue, Epic integration, clinician trust, human-machine teamwork, and measuring outcomes safely. The conversation also looks at expanding AI beyond sepsis to prevent respiratory failure, bleeding, cardiac events, and other avoidable harm.

#316 - What Should You Actually Do About High Cholesterol? | Dr. Seth Martin & Mike Haney
Dr. Seth Martin, a Johns Hopkins preventive cardiologist and lipid specialist, joins Mike Haney for a practical tour of modern cholesterol care. They explore why LDL and ApoB matter, when newer risk tools and coronary calcium scans can guide treatment, why particle-size tests fall short, and how statins, lifestyle changes, and non-statin therapies fit together. They also tackle muscle symptoms, diabetes risk, and the limits of supplements.

#315 - Can We Treat Disease Through the Nervous System? | Dr. Kevin Tracey & Mike Haney
Dr. Kevin Tracey, neurosurgeon, scientist, and bioelectronic medicine pioneer, explores how the nervous system could become a therapeutic target. They discuss why the vagus nerve is really 160,000 specialized fibers, how stimulation led to an FDA-approved rheumatoid arthritis treatment, the promise of fiber-specific therapies, and why inflammation, HRV, breathing, and cold exposure are harder to measure than online claims suggest.

#314 - How to Make Health Decisions When the Science Is Unclear | Dr. Anupam Jena & Mike Haney
Dr. Anupam Jena, Harvard physician, health economist, and Freakonomics, M.D. presenter, joins Mike Haney to explore smarter health decisions amid conflicting evidence. They examine what observational studies, randomized trials, and meta-analyses can and cannot show, why absolute risk matters, how personal experiments can mislead, and how potential harm, plausibility, evidence quality, and cost should shape the decision to try an intervention.

#313 - What Happens When We Start Imaging Healthy People? | Dr. Daniel Durand & Mike Haney
Dr. Daniel Durand, Prenuvo’s chief medical officer and a Johns Hopkins-trained radiologist, explores what happens when healthy people start getting imaged. He and Mike Haney debate whole-body MRI, radiation-free screening, incidental findings, anxiety, and the value of repeat scans. They also look ahead to AI, faster imaging, and combining MRI with genomic and other health data.

#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.
