The Jesse Chappus Show 682: 1/2 Cup per Day to Fix Insulin Resistance & Shrink Belly Fat | Dr. William Davis
Dec 9, 2025
Dr. William Davis, a cardiologist and author of the bestselling book Wheat Belly, shares insights on overcoming insulin resistance. He explains why improving body composition matters more than mere calorie-counting, detailing strategies to rebuild muscle after dieting. Davis emphasizes the impact of small intestinal bacterial overgrowth (SIBO) on weight and insulin resistance, along with testing techniques. He also discusses the importance of fermented probiotics, specifically in yogurt-making, and their role in enhancing gut health and overall well-being.

SIBO As A Hidden Metabolic Driver
- Small intestinal bacterial overgrowth (SIBO) with fecal microbes causes endotoxemia and drives insulin resistance, myosteatosis, and weight gain.
- Davis estimates SIBO affects roughly 50% of North Americans and is a major metabolic driver.
Treat SIBO With Targeted Ferments
- Use targeted human-derived microbes that colonize the small intestine and produce bacteriocins to displace fecal SIBO species.
- Fermented yogurt-like recipes of selected strains (e.g., L. reuteri, L. gasseri, Bacillus subtilis) can normalize hydrogen/methane tests for most people.
Ferment Separately To Maximize Counts
- Ferment strains separately when you need maximum counts, especially after heavy antibiotic exposure or severe SIBO.
- Higher counts (tens of billions) increase potency versus co-fermented blends that compete and yield fewer cells.
