    EXPLAINER: What Happens to Your Body in 5 Days Without Ultra-Processed Food

    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 NIH metabolic ward data showing a 500+ calorie daily swing driven entirely by food processing - not willpower.

    The 91-Year-Old Physicist Betting His Body on Mitochondrial Transplant | John Cramer PhD

    What if aging isn't a hundred separate problems but a single one — an energy crisis inside the tiny power plants of every cell? At 91, Dr. John G. Cramer is betting his own body on the answer. In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Dr. John G. Cramer — Emeritus Professor of Physics at the University of Washington and author of "How to Live Much Longer" — the oldest human on Earth to receive an experimental mitochondrial transplant. They unpack a unifying theory of aging built around damaged mitochondrial DNA, why replication errors (not just free radicals) drive most of the damage, and what it felt like to receive escalating doses of "Mitlets" — liposomes carrying fresh mitochondria harvested from young blood platelets — at a Texas right-to-try clinic.

    EXPLAINER: 3 Blood Tests Your Doctor Skips (That Predict Heart Attacks & Alzheimer's)

    Your doctor orders a lipid panel every year — but 3 cheap blood tests predict heart disease, diabetes, and even dementia far better than cholesterol, and most doctors never order them. In this episode, Robert Lufkin MD walks through fasting insulin + HOMA-IR, homocysteine, and high-sensitivity CRP — three tests that together cost about $60, take one blood draw, and catch the metabolic dysfunction a standard lipid panel systematically misses. CHAPTERS: 00:00 — The 3 Blood Tests Your Doctor Isn't Ordering 00:40 — Part 1: Fasting Insulin and HOMA-IR 01:15 — How Insulin Resistance Hides for 10–15 Years 01:45 — HOMA-IR vs Glucose: What 516,000 People Revealed 02:05 — 59% Higher Cardiovascular Risk in the 2023 ATVB Study 02:45 — Optimal Fasting Insulin: Why 5–8 Beats the Lab's "25" 03:05 — Part 2: Homocysteine and the MTHFR Connection 03:35 — How Homocysteine Damages Your Arteries (6 Mechanisms) 03:50 — 60% Higher Stroke Risk and 48% Alzheimer's Risk 04:35 — The Oxford VITACOG Trial: 53% Less Brain Atrophy 05:05 — Part 3: High-Sensitivity CRP and Inflammatory Plaque 05:40 — The JUPITER Trial: 44% Drop in Cardiac Events 06:15 — UK Biobank: Why hs-CRP Beats LDL Cholesterol 06:50 — AHA Risk Categories for hs-CRP Since 2003 07:15 — Part 4: The Metabolic Picture (Why Cholesterol Is the Wrong Target) 07:50 — 3 Tests, $60, One Blood Draw — The Full Framework KEY TAKEAWAYS: Fasting insulin + HOMA-IR catches insulin resistance a decade before glucose goes abnormal — optimal is below 5–8, not the lab's reference range of 25 Every 5 µmol/L rise in homocysteine raises coronary artery disease risk 20–30% and stroke risk 60%, independent of cholesterol hs-CRP predicted cardiovascular events better than LDL in a 322,000-person UK Biobank analysis — yet fewer than 10% of cardiac panels order it Cardiovascular disease, type 2 diabetes, and dementia share the same upstream driver: metabolic dysfunction, not cholesterol All three tests together cost roughly $60 and come from a single blood draw LINKS: 📖 Dr. Lufkin's book "Lies I Taught in Medical School": robertlufkinmd.com/lies 📰 Substack: robertlufkinmd.substack.com 🌐 Website: robertlufkinmd.com ▶️ Watch on YouTube: youtu.be/FBLB1CQGBPM ⭐ Enjoying the show?

    Your Phone Is Rewriting Your Biology — Daniel DeBaun (Former Bell Labs Engineer)

    What if the single device you hold closest to your body for 10+ hours a day is quietly rewriting your biology — and your grandchildren's? In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Daniel DeBaun — a former Bell Labs and AT&T telecom engineer who helped build the very wireless standards the industry still runs on, then walked away to warn us about them. He is the founder and CEO of DefenderShield and co-author of "Radiation Nation," and he pulls back the curtain on what 4G, 5G and the coming 6G are actually doing to the human body, the gut microbiome, fertility, and the developing child.

    A ketogenic diet put his ulcerative colitis into complete remission — off all medications, confirmed on colonoscopy.
