About

David L. Katz, MD, MPH, FACPM, FACP, FACLM earned his BA at Dartmouth College (1984); his MD at the Albert Einstein College of Medicine (1988); and his MPH from the Yale University School of Public Health (1993). He completed sequential residency training and board certification in Internal Medicine (1991) and Preventive Medicine/Public Health (1993).

Katz is the founder and former director of Yale University’s Yale-Griffin Prevention Research Center (1998-2019); Past President of the American College of Lifestyle Medicine; President and Founder of the non-profit True Health Initiative; Founder and CEO of Diet ID, Inc; and Chief Medical Officer for Tangelo (food-as-medicine). He is a Fellow of the American College of Preventive Medicine; the American College of Physicians; the American College of Lifestyle Medicine; and Morse College, Yale University.

The recipient of numerous awards for teaching, writing, and contributions to public health, Katz was a 2019 nominee for a James Beard Foundation Award in health journalism, has been a widely supported nominee for the position of U.S. Surgeon General, and has received three honorary doctorates.

Katz has an extensive media portfolio, having served as a nutrition columnist for O, the Oprah Magazine; an on-air contributor for ABC News/Good Morning America, and with appearances on most major news programs and contributions to most major magazines and leading newspapers, including OpEds in the New York Times and Wall Street Journal. He is one of the original 150 “Influencers” selected by LinkedIN, and has a social media following of nearly one million.

He holds multiple US patents; has roughly 250 peer-reviewed publications; has published many hundreds of on-line and newspaper columns; and has authored/co-authored 19 books to date including multiple editions of leading textbooks in nutrition, preventive medicine, and epidemiology. He is the inventor of several innovations in clinical research methodology, including the evidence mapping.

His career-long focus has been the translation of science into action for the addition of years to life, and life to years.

On the COVID pandemic, he advocated for a policy of total harm minimization (https://www.truehealthinitiative.org/covid/) by means of risk-stratified interdiction efforts.


Katz has presented at conferences in all 50 states and in multiple countries on six continents. He has been recognized by peers as the “poet laureate of health promotion.”

He and his wife, Catherine, live in Connecticut. They have five grown children.

    The leading causes of mortality and healthcare costs worldwide are chronic diseases, resulting from lifestyle and environmental factors.

    The leading causes of mortality and healthcare costs worldwide are chronic diseases, resulting from lifestyle and environmental factors. The economic burden of poor lifestyle choices is no longer sustainable and impossible to ignore. Most chronic diseases are preventable. To treat the causes of these diseases and to be successful in prevention, a strong focus must be placed on lifestyle medicine aspects. Lifestyle Medicine encompasses research, prevention, diagnosis and treatment of dysfunctions caused by a non-physiological lifestyle (lifestyle-related diseases, LRDs) and morbidogenic environments conducive to promoting such lifestyles. The ultimate goal and primary focus of Lifestyle Medicine is to promote healthier lives through salutary environments and healthier lifestyle choices. Treatment of LRDs includes nutritional, exercise, psychological, social, economic and environmental interventions. To successfully do this requires education, training and communication about Lifestyle Medicine at the professional and general public level, while avoiding the trap of ‘victim blaming’ of individuals whose lifestyles are influenced by circumstances beyond their control.
