Summary

Cardiologist William Davis argues that modern wheat, a product of genetic modifications since the 1960s, is the primary driver of the obesity and diabetes epidemics. He contends that wheat consumption triggers insulin production-the fat-storage hormone-and acts as an appetite stimulant by interacting with opiate receptors in the brain. Davis advises that eliminating wheat can reverse chronic health issues, including high blood sugar, hypertension, and digestive problems.

The “Wheat Belly” protocol advocates for a diet free of all grains and processed gluten-free substitutes. Instead, it promotes the consumption of real, single-ingredient foods like vegetables, meats, eggs, and healthy fats. Key to the diet is strict carbohydrate management, limiting net carbs to 15 grams per meal, with no restrictions on fats or oils. Davis also emphasizes the importance of restoring gut health through probiotics and prebiotics, and managing the initial withdrawal symptoms from grain-derived opiates with hydration and magnesium supplementation.
