A Hidden Cause Behind Chronic Disease: Dr. William Davis on Microbiome Disruption & Rebuilding Gut Health

In this eye-opening episode of The Health and Wellness Coach Journal Podcast, Dr. Jessica Singh speaks with Dr. William Davis, a cardiologist and New York Times bestselling author of Wheat Belly, Wheat Belly Cookbook, Wheat Belly 30-Minutes (or Less!) Cookbook, and Wheat Belly Total Health, as well as Wheat Belly 10-Day Grain Detox, Undoctored, and Super Gut. His newest book, Super Body: A 3-Week Program to Harness the New Science of Body Composition and Restore Your Youthful Contours, explores emerging science on body composition, the microbiome, and long-term metabolic health. Dr. Davis shares how his work as a cardiologist—and a personal turning point—led him to reexamine conventional approaches to heart disease risk. He discusses why wheat and sugar contribute to metabolic changes that negatively affect whole-body health. The discussion moves beyond diet to explore why removing harmful foods may only be the beginning. Dr. Davis explains how antibiotics, numerous medications, modern food, environmental exposures, chronic stress, and disrupted sleep deplete protective microbes, impacting various aspects of health. This episode also explores microbiome implications for women’s and maternal health, infant development, SIBO, and the relationship between stress, sleep, circadian rhythm, and the gut–brain axis. Dr. Davis offers practical guidance for coaches and healthcare providers seeking credible, evidence-informed microbiome resources. Together, Dr. Singh and Dr. Davis discuss the education gap in medicine—particularly around nutrition and the microbiome—and why clinicians often need to expand beyond traditional training to support prevention and long-term healing. This conversation is a call to rethink prevention and recognize that rebuilding the microbiome is a powerful way to reclaim agency and improve health.
