Dr. William Li Crosses 1 Million on Both YouTube and Facebook
Milestone reflects the rapid expansion of his global digital health platform
BOSTON, Sept. 16, 2026 /PRNewswire-PRWeb/ -- Physician-scientist, two-time New York Times bestselling author, and internationally recognized authority on food as medicine and health, William W. Li, MD, has reached two major digital milestones: one million subscribers on YouTube and one million followers on Facebook. Together with more than 830,000 followers on Instagram, his combined following across the three platforms is nearing three million.
The growth reflects rising demand for credible health information that makes complex science understandable and useful in everyday life.
Dr. Li's YouTube channel (@drwilliamli) has grown from fewer than 100,000 subscribers in 2023 to one million today. In the 28 days leading up to the milestone, the channel generated approximately 7.9 million views, more than 303,000 hours of watch time, and 40,000 new subscribers.
Through long-form videos, short-form content, interviews, and social media, Dr. Li translates health science into practical insights on food as medicine, metabolism, gut health, immunity, inflammation, cardiovascular health, cancer, healthy aging, and the body's natural health defense systems.
"This milestone belongs to a community of people who truly want to understand their health and take meaningful action," said Dr. Li. "Science can transform lives, but only when people understand it and see how it applies to the choices they make every day. That's the purpose behind everything I create."
Dr. Li is President and Medical Director of the Angiogenesis Foundation, a nonprofit organization dedicated to improving global health through angiogenesis-based science, prevention, and treatment. His scientific work has been published in leading medical journals, and his TED Talk, "Can We Eat to Starve Cancer?", has been viewed more than 11 million times. His books, Eat to Beat Disease and Eat to Beat Your Diet, have been translated into 20 languages.
As his digital platform enters its next phase, Dr. Li and his team are developing original programming, educational experiences, media projects, and select strategic collaborations across food, health, longevity and healthspan, technology, travel, culinary culture, and lifestyle. Scientific credibility and rigorous standards will remain central to that growth.
