Dean Ornish

A bestselling author of six books, Dean Ornish, MD, is founder and president of the nonprofit Preventive Medicine Research Institute and a clinical professor of medicine at the University of California San Francisco and the University of California San Diego. He directed groundbreaking randomized trials that showed, for the first time, that a healthy lifestyle — eating well, moving more, stressing less, loving more — could often begin to reverse many common (and costly) chronic diseases, without drugs or surgery. Medicare created a new benefit category to reimburse patients of his lifestyle medicine program, and the "Ornish diet" was rated "#1 for Heart Health" by U.S. News & World Report.
