Cancer Scientist: This Common Daily Diet May Be Feeding Cancer! - Thomas Seyfried

29 segments available

1,700 Americans will die from cancer today. 70 every single hour. Professor Thomas Seyfried says it doesn't have to be this way, and that mainstream oncology has been wrong about cancer for 100 years. Thomas Seyfried, PhD, is a professor of biology at Boston College and one of the world's leading researchers on the metabolic origins of cancer. He is author of the book 'Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer' and co-developer of the Glucose Ketone Index (GKI) and the “press-pulse” therapeutic strategy. He explains: ◼ Why he believes cancer is a mitochondrial metabolic disease, not a genetic one ◼ Why cancer cells can't survive without two fuels and the strategy his team uses to starve tumors ◼ How a ketogenic diet lowers your GKI and makes chemo and immunotherapy work better ◼ The environmental drivers quietly damaging your mitochondria ◼ How his team is keeping glioblastoma patients alive for years, and why almost no patient is ever told this option exists The views expressed are those of the guest, and this conversation is intended for general informational purposes only. This podcast and its associated materials should not be used as a substitute for professional medical advice, diagnosis, or treatment. 00:00:00 Intro 00:02:42 The New Discovery About Cancer 00:03:43 What Role Do Mitochondria Play in Cancer? 00:06:22 How Damaged Mitochondria Cause Cancer 00:08:12 ATP & Fermentation: How Your Cells Make Energy 00:15:00 The Oncogenic Paradox Finally Explained 00:20:19 Ghost Mitochondria: Cancer Under the Microscope 00:25:19 Glucose & Glutamine: The Fuels That Feed Cancer 00:26:32 Why Do Children & Babies Get Cancer? 00:29:25 Why Wealthy Countries Have More Cancer 00:32:55 Is Cancer Genetic? 00:37:58 The Prescription: The Glucose Ketone Index 00:40:23 How Stress & Poor Sleep Fuel Cancer 00:44:54 What's Inside the Confidential Envelope? 00:45:58 The Patient Who Inspired the Discovery 00:50:25 Measuring Your Glucose Ketone Index Live 00:53:01 The 'Red Zone' Could Cause Cancer 00:58:02 The Man Who Survived Glioblastoma for 10 Years 00:58:55 Using the Keto Diet to Supercharge Chemo 01:07:32 The Experiment That Could Prove Cancer Isn't Genetic 01:08:30 1,700 Cancer Deaths a Day: Seyfried's Warning 01:13:41 Seyfried's Plan to End the Cancer Epidemic 01:16:25 What Foods You Should Actually Eat 01:21:58 Fasting Protocols & Hitting 'The Wall' 01:26:48 Hyperbaric Oxygen Therapy & Cancer 01:28:30 Microplastics & 'Forever Chemicals' 01:30:47 How Cancer Spreads: Metastasis Explained 01:37:27 The #1 Actionable Takeaway 01:39:45 Energy, Hope & Final Words Independent Fact Check: https://stevenbartlett.com/wp-content/uploads/2026/07/DOAC-Dr.-Thomas-N.-Seyfried-Independent-Research-Further-Reading.pdf Thomas Seyfried's Metabolic Health Assessment: https://stevenbartlett.com/wp-content/uploads/2026/07/Proposed-glucose-ketone-index-GKI-zones.webp Follow Professor Thomas: ◼Instagram - https://link.thediaryofaceo.com/1MRuOwr ◼X - https://link.thediaryofaceo.com/DDF9xxr ◼Substack - https://link.thediaryofaceo.com/HKsGFcF ◼ Professor Seyfried's Biology Department - https://link.thediaryofaceo.com/HKwWhwD ◼ Foundation for Cancer Metabolic Therapies - https://link.thediaryofaceo.com/6Ehj3Hh ◼ Elizabeth Ann Weathers Breast Cancer Research Fund - https://link.thediaryofaceo.com/Bf10aHy Supporting Professor Seyfried's Cancer Metabolic Therapy Research: A message from Professor Seyfried: “If you would like to support research on the mitochondrial metabolic theory of cancer, please consider donating to our research.
