Dean Ornish, M.D.
President and Founder, Preventive Medicine Research Institute, Clinical Professor of Medicine, University of California San Francisco
Dr. Ornish is the founder and president of the nonprofit Preventive Medicine Research Institute in Sausalito, Calif. He is clinical professor of medicine at the University of California, San Francisco.
For more than 32 years, Dr. Ornish has directed clinical research demonstrating, for the first time, that comprehensive lifestyle changes may begin to reverse even severe coronary heart disease, without drugs or surgery. He directed the first randomized, controlled trial demonstrating that comprehensive lifestyle changes may stop or reverse the progression of early-stage prostate cancer. His research showed that comprehensive lifestyle changes affect gene expression, “turning on” disease-preventing genes and “turning off” genes that promote cancer and heart disease. In collaboration with Nobel laureate Elizabeth Blackburn, Ph.D., he also showed that these lifestyle changes can lengthen telomeres, the ends of chromosomes that control how long we live.
He is the author of six best-selling books, including New York Times best-sellers Dr. Dean Ornish's Program for Reversing Heart Disease; Eat More, Weigh Less; Love & Survival; and his most recent book, The Spectrum.
The research that he and his colleagues conducted has been published in the Journal of the American Medical Association, The Lancet, Proceedings of the National Academy of Sciences, Circulation, TheNew England Journal of Medicine, the American Journal of Cardiology, The Lancet Oncology, and elsewhere.

Hana Kahleova, M.D., Ph.D.
Physicians Committee for Responsible Medicine
Dr. Kahleova is director of clinical research for the Physicians Committee for Responsible Medicine. She is an endocrinologist with a doctorate in human physiology and pathophysiology. Her current research interests focus on dietary treatment of metabolic disease and type 2 diabetes. She conducted several clinical trials with a plant-based diet. The studies proved the power of a plant-based nutrition to improve oxidative stress and metabolic control in patients with type 2 diabetes. One of the studies showed that a plant-based diet reduces muscle fat more than a conventional hypocaloric diet in people with type 2 diabetes. This reduction in muscle fat was also associated with improvements in glucose metabolism and insulin sensitivity. Her research proved that eating a large breakfast and lunch is more beneficial than eating six smaller meals a day for patients with type 2 diabetes. She completed her postdoctoral research fellowship at Loma Linda University in California, analyzing data from more than 50,000 people, who were followed up for more than 7 years, on meal frequency and timing in relationship to body weight regulation.
