What if we've been looking at cancer the wrong way for more than 70 years?
In this episode of the ReThink Health Podcast, I sit down with Dr. Thomas Seyfried, a professor of biology at Boston College and author of Cancer as a Metabolic Disease. For decades he has asked a question most of oncology stopped asking long ago: what if cancer isn't driven mainly by bad genes?
This conversation is deeply personal for me. My dad battled cancer three times, and I recently lost him. Two of my close friends, one in her 40s and one in his 50s, are facing cancer right now. Dr. Seyfried's work was a source of hope for our family, and I know cancer touches almost everyone's life.
Dr. Seyfried explains why he believes cancer is primarily a mitochondrial metabolic disease. His argument builds on the work of Nobel laureate Otto Warburg and on his own lab's research into how cancer cells rely on two fuels: glucose and glutamine. He walks us through the nuclear transfer experiments that challenged the gene-centered view of cancer. He also explains why cancer cells "ferment" for energy instead of "breathing" like healthy cells.
You'll learn:
Why Dr. Seyfried believes the gene mutations found in cancer are an effect of the disease rather than its cause
The difference between fermentation and respiration, and why cancer cells keep fermenting even when oxygen is present
Why he says glucose and glutamine must be targeted together, and how his "press-pulse" strategy works
How to use the Glucose-Ketone Index to see where your metabolism stands
Why ketones are often called a "super fuel" for healthy cells
How alcohol, portion size, exercise, stress, and fasting affect your glucose ketone index (GKI)
What forever chemicals and rising childhood obesity may mean for cancer rates in kids
What a day of eating and living looks like for a researcher who has studied cancer for 40 years
If you or someone you love has been touched by cancer, this episode offers a different perspective and practical tools to bring to your conversations with your healthcare team.
