Cancer Is NOT a Genetic Disease? Dr. Thomas Seyfried Explains the Metabolic Theory

Is everything we’ve been told about cancer wrong?

In this episode of UltraLife Today, Boston College biology professor Dr. Thomas Seyfried explains why he believes cancer is not primarily a genetic disease—but a mitochondrial metabolic disease fueled by disordered energy production.

Dr. Seyfried walks us through:
* Why the dominant “cancer is a genetic disease” model is breaking down
* The experiments showing that damaged mitochondria, not mutated DNA, drive tumor growth
* What Otto Warburg got right (and what he didn’t know) about cancer metabolism
* How cancer cells ferment glucose and glutamine even in the presence of oxygen
* Why this shift in understanding could change how we prevent and manage cancer
* The basics of the Glucose Ketone Index (GKI) and why metabolic health matters for all chronic disease

If you or someone you love is facing cancer, this conversation is essential viewing.👉 Share this with anyone who has an active diagnosis or is at high risk.

🔔 Part 2 coming next week – where we get practical about:
* Metabolic strategies and diet
* Exercise & mitochondria
* Supplements & common questions (including “repurposed” drugs)

🧬 About Dr. Thomas Seyfried
Dr. Seyfried is a professor of biology at Boston College and author of “Cancer as a Metabolic Disease: On the Origin, Management and Prevention of Cancer.” His work builds on and expands the Warburg hypothesis, arguing that mitochondrial dysfunction and fermentation are at the heart of cancer biology.
