Michael Greger, M.D.: The Evidence-Based Advocate
Often cited as the most famous vegan doctor in modern media, Dr. Michael Greger is the physician and founder of NutritionFacts.org, a nonprofit website providing free, science-based videos and articles on all aspects of healthy eating. A founding member of the American College of Lifestyle Medicine, Greger's work is renowned for its accessibility and its foundation in peer-reviewed scientific literature. His mission is to make evidence-based nutritional science accessible to the public, funded entirely by donations and the proceeds from his best-selling books.
Bestselling Books and Public Speaking
Dr. Greger’s fame skyrocketed with his New York Times best-selling book, How Not to Die, in which he outlines the leading causes of premature death in America and explains how a plant-based diet can help prevent, and in some cases, reverse them.

His engaging public speaking, including testimony before Congress and appearances as an expert witness, has cemented his status as a leading voice in vegan health advocacy.

Caldwell Esselstyn, M.D.: Pioneer of Heart Disease Reversal
Dr. Caldwell B. Esselstyn Jr. is another highly famous vegan doctor, particularly within the field of cardiology. He is best known for his groundbreaking work on the reversal of coronary artery disease through a low-fat, whole-foods, plant-based diet. A former Olympic gold medalist and surgeon, Dr. Esselstyn’s research at the Cleveland Clinic demonstrated that this dietary intervention could halt and reverse heart disease in severely ill patients. His work was famously embraced by former U.S. President Bill Clinton after his own health crisis.
Impactful Publications and Documentaries
Dr. Esselstyn’s seminal book, Prevent and Reverse Heart Disease, details his nutritional program and the clinical evidence supporting it. He was also a featured doctor in the acclaimed 2011 documentary Forks Over Knives, which further popularized his findings and the broader plant-based movement. His decades of research provide a powerful testament to the impact of diet on cardiovascular health.
Neal Barnard, M.D.: Champion for Responsible Medicine
Dr. Neal Barnard is a physician, president of the Physicians Committee for Responsible Medicine (PCRM), and adjunct professor of medicine at the George Washington University School of Medicine.
