William Davis, MD Biography

Dr. William Davis is a preventive cardiologist and New York Times bestselling author recognized for challenging conventional perspectives on diet, heart disease, and human health. Davis earned his MD from St. Louis University and completed cardiology and interventional cardiology fellowships at Ohio State University and Case Western Reserve. He began his career as a conventionally trained cardiologist specializing in procedures such as stents and coronary interventions. Following the sudden cardiac death of his mother despite standard treatment, Davis reevaluated traditional approaches to heart disease, ultimately focusing on metabolic and inflammatory factors influenced by diet, micronutrients, and the gut microbiome.

Davis is the author of the New York Times bestselling book "Wheat Belly: Lose the Wheat, Lose the Weight, and Find Your Path Back to Health," published in 27 countries. The book presents the argument that modern semi-dwarf wheat, developed during the Green Revolution, is a uniquely harmful food compared to its ancient predecessors. "Wheat Belly" became a bestseller shortly after publication, selling over three million copies in 40 countries. Davis has also authored additional New York Times bestsellers, including "Wheat Belly Cookbook," "Wheat Belly 30-Minute (or Less!) Cookbook," and "Wheat Belly Total Health," as well as "Wheat Belly 10-Day Grain Detox" and "Undoctored."

His book "Super Gut: A Four-Week Plan to Reprogram Your Microbiome, Restore Health and Lose Weight" outlines the impact of modern lifestyles on the human microbiome and provides actionable steps for restoration. Davis's work explores the role of specific probiotic strains in promoting gut health, reducing disease risk, and influencing emotional well-being. He is co-founder and chief medical officer of Realize Therapeutics Corp., a company focused on research and development of therapeutic products based on microbiome science.

Davis has appeared on national media outlets including The Dr. Oz Show, CBS This Morning, National Public Radio, and Live with Kelly, as well as features on The Colbert Report and in print media such as First for Women, Woman's World, New York Post, Chicago Tribune, The Atlantic, and Women's Health. His "Wheat Belly Total Health" program has also been adapted into a public television special. Davis maintains a significant online presence, with millions of visitors to his "Wheat Belly" blog, hundreds of thousands of followers on Facebook, and millions of views on YouTube.

Davis is the founder and medical director of the Infinite Health Program and the Infinite Health Inner Circle, where he provides science-based strategies for restoring gut health, addressing chronic conditions, and supporting long-term wellness. Through his books, programs, recipes, and the "Defiant Health" podcast, Davis continues to advance a movement toward grain-free, microbiome-focused living and patient-centered preventive cardiology.

We are on the cusp of a dramatic disruption of the notion of healthcare.

  • Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health

    I recount how and why we find ourselves in a peculiar predicament: a human diet largely reliant on the seeds of grasses--"grains"--an unnatural situation made worse by the fiddling of agribusiness and genetics research. But understand a handful of basic principles and listeners are provided astounding personal control over health and weight.
