Dr. William Davis, MD

Dr. William Davis is a cardiologist and author of 6 books, including the New York Times bestseller Wheat Belly. He has been featured in major media outlets, including The Dr. Oz Show, Fox TV, the New York Times, the Los Angeles Times, and Huffington Post. After 25 years practicing cardiology, Dr. Davis became acutely aware that he was in the business of dispensing prescription drugs and procedures, not health. So he began to seek out ways to restore health naturally, logically, and inexpensively — and discovered that managing the human microbiome is key to better health, weight management, and longevity. This course is the culmination of those findings.
