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

TL;DR

Thomas Seyfried argues that cancer is a mitochondrial metabolic disease, not a genetic one: damage to the mitochondria from factors like processed carbohydrates, inactivity, chronic stress, poor sleep, and environmental carcinogens forces cells back into ancient fermentation pathways, causing dysregulated growth.

Key insights

• All chronic diseases (cancer, type 2 diabetes, cardiovascular disease, dementia, neuropsychiatric disorders) stem from chronic damage to mitochondrial oxidative phosphorylation; the organelle determin
• Cancer cells continue to ferment (produce lactic and succinic acid) even in 100% oxygen because their mitochondria are structurally and functionally corrupted; they cannot burn fatty acids or ketones
• The GKI (glucose in millimolar divided by ketones in millimolar) provides a stable, actionable measure of mitochondrial health; a GKI < 12.5 places a person in the “zone of prevention,” while higher v
