Episode 266: Dr. William Davis

September 10, 2025·1 hr 3 min·1 clip

My mom died of the disease that I worked on every day—that was a kick upside the head.

Dr. William Davis, cardiologist and author of Wheat Belly and Super Gut, joins Brian Lenskis to dismantle conventional cardiovascular medicine. After his mother's death from heart disease despite successful intervention, Davis spent 30+ years developing an alternative framework: heart disease is a dietary (grain/sugar-driven) and microbiome disorder, not a cholesterol problem. He replaced cholesterol testing with lipoprotein particle counting (NMR), revealing that wheat and grains uniquely trigger small LDL formation via hepatic VLDL production. Dysbiosis—specifically small intestinal overgrowth of gram-negative bacteria—perpetuates this via endotoxemia. Host validates with clinical data: carnivore dieters lacking prebiotic fiber develop C. difficile colitis and inflammatory dysbiosis, yet adding inulin restores butyrate-producers, normalizes lipids, and reverses metabolic dysfunction. Episode bridges cardiology, gastroenterology, and nutrition science.
