Diet of Hope Institute

OUR FOUNDERS

Dietmar Gann MD, FACC, FCCP and Elizabeth Gann MBA, CNC

In 2010 Dr. Gann and his wife Elizabeth created Diet of Hope to fill a need in the healthcare world.  Dr. Gann was born in Germany and later migrated to the United States, where he established a long and successful career as a medical professional, contributing immensely to the betterment of the lives of countless people. Dr. Gann became interested in a dietary approach to treating heart disease, hypertension and diabetes while running a successful cardiology practice. He decided to perform a study with his own patients who were struggling with heart disease and put them on a low carbohydrate diet. He noticed that his patients were successfully reducing most of their coronary risk factors. It was published in the American Journal of Cardiology. It was at that time that the seed of Diet of Hope Institute was planted. Dr. Gann along with his wife Elizabeth, a 2005 National Minority Female Entrepreneur recipient, began their Journey to developing the dietary plan for the Diet of Hope Institute. 

Dr. Gann passed away in 2023 but under the leadership of his wife Elizabeth his legacy lives on at Diet of Hope Institute.
