Food Junkies Podcast Episode 228: Dr. Thomas Seyfried - Cancer as a Metabolic Disorder
In this compelling episode, Dr. Vera Tarman interviews Dr. Thomas Seyfried, a pioneer in the field of cancer metabolism. Dr. Seyfried challenges the mainstream view of cancer as a genetic disease and presents strong evidence that cancer is fundamentally a mitochondrial metabolic disorder.
Dr. Thomas N. Seyfried is a distinguished American biologist and professor at Boston College, renowned for his pioneering work in cancer metabolism. With a Ph.D. in Genetics and Biochemistry from the University of Illinois, Urbana, and postdoctoral training in neurochemistry at Yale University School of Medicine, Dr. Seyfried has dedicated his career to exploring the metabolic underpinnings of cancer and other neurological diseases.
Dr. Seyfried is best known for his groundbreaking book, Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer (2012), where he presents compelling evidence that cancer is primarily a mitochondrial metabolic disorder rather than a genetic one. This perspective builds upon the early 20th-century findings of Otto Warburg, who observed that cancer cells rely heavily on fermentation for energy production, even in the presence of oxygen—a phenomenon known as the Warburg effect. Dr. Seyfried's research suggests that targeting cancer's metabolic dependencies, such as glucose and glutamine, through dietary interventions like the ketogenic diet, could offer non-toxic therapeutic strategies.
We explore:
How cancer cells fuel themselves differently from healthy cells The connection between sugar, ultra-processed foods (UPFs), and cancer growth The Warburg Effect and the roles of glucose and glutamine in tumor development Whether refined sugar is carcinogenic like tobacco Why Dr. Seyfried believes ketogenic diets and caloric restriction can be powerful cancer therapies How his views align with metabolic psychiatry (Dr. Chris Palmer’s Brain Energy) The controversial yet promising approach of "press-pulse" therapy The potential for preventing cancer through dietary change
