EXPLAINER: What Happens to Your Body in 5 Days Without Ultra-Processed Food
Health Longevity SecretsShow Notes
Ultra-processed food makes up over half the calories Americans eat - and over 60% for kids. Here's what the research shows happens inside your body in the first 5 days after you quit. In this episode of Health Longevity Secrets, Dr. Robert Lufkin walks through the hour-by-hour timeline: the glucose spikes that disappear within 24 hours, the insulin resistance that drops 30%+ in 48 hours, the gut microbiome that reorganizes in 3 days, the blood pressure that falls 6-8 mmHg in a week, and the N...

Elizabeth Holmes went to prison for promising hundreds of blood tests from a single drop of your finger. Some of what she promised is now FDA cleared, and some of it may never be possible at all. With the new documentary You Can See Everything in theaters, Robert Lufkin MD looks at what Theranos promised, what really happened, what is actually FDA cleared in 2026, the physics of a single drop, and which home and finger-stick tests you can trust.

A young scientist died in a Russian plague lab. Officials deny an accident. Is biowarfare a real threat, or is the bigger risk something else? Robert Lufkin MD looks at the death of a young lab worker at Russia's Irkutsk anti-plague institute, why Moscow's denials are hard to take at face value, and what Annie Jacobsen's book Biological War: A Scenario gets right and wrong. Untreated pneumonic plague is almost always fatal. The right antibiotics cut deaths sharply. A strain that shrugs off t...
She lived to 117 — and when scientists sequenced everything from her genome to her gut bacteria, they found a paradox that rewrites what aging has to look like. In this episode, Robert Lufkin MD breaks down the landmark multiomics study of Maria Branyas Morera, the world's oldest verified person, published in Cell Reports Medicine (2025) by the Esteller lab. The study mapped her genome, epigenome, proteome, metabolome, and microbiome — and found a body that was simultaneously very old and bio...
A facial plastic surgeon reveals the MRI data on "Ozempic face," why repeated masseter Botox can thin the jawbone, and the topical rapamycin resetting skin cells to a 20-year-old phenotype. In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Dr. Kay Durairaj, a USC and UCLA-trained facial plastic surgeon bringing evidence-based medicine to the longevity-aesthetics frontier. Old friends from their UCLA head and neck tumor-board days, they dig into the science most aest...
Will AI cure all disease? 90% of biomedical papers published in December 2025 show signs of AI assistance — and the Nobel laureate behind AlphaFold says AI could help end all disease within a decade. In this episode, Robert Lufkin MD examines what artificial intelligence is really doing to health science: the quiet takeover of the scientific paper, the first AI-discovered drug to pass a Phase 2a trial, robot laboratories running experiments around the clock, and the honest caveats behind the ...
