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 misunderstood 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 feed on two fuels and the strategy his team uses to starve tumors
◼ How a ketogenic diet could lower your GKI and make 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
