About David Katz

David L. Katz was born on February 20, 1963, in Los Angeles, California.[3] His father was an internist and cardiologist. He explained why he wanted to become a doctor when he said, “I revere medicine. I was raised with the Calvinist principles that you work hard and contribute something. I wanted to do something that mattered.”[4] 

Katz studied French at Dartmouth College, earning his bachelor’s degree in 1984.[5] He then moved to New York to attend Albert Einstein College of Medicine, earning his MD in 1988. After medical school, Katz completed two residency programs, the first in internal medicine and the second in preventive medicine and public health. While in his second residency, he also completed a Master’s of Public Health at Yale University.[2]  

Katz met his future wife, Catherine, while at Yale. Catherine was a neuroscience post-doc born in Africa and raised in France.[6] Katz says, “Catherine loved food in a different way than I did. I was committed to nutrition and was willing to eat tree bark and gravel if it had nutritional value, but Catherine was a foodie.”[4] 

After their marriage, the Katzs combined their love of nutrition and food to collaborate on several books. They now have five children together, Rebecca, Corinda, Valerie, Natalia, and Gabriel.[4] 

In 2015, Katz faced criticism when he used his platform as a columnist at The Huffington Post to praise a science-fiction book he had written under a pseudonym. He said the book had “lyrically beautiful writing” but did not disclose he was the book’s author until the following year.[7]

From 2008 to 2015, Katz worked as the chief science officer at the nutrition company NuVal. From 2014 to 2016, Katz was president of the American College of Lifestyle Medicine.[5] 

Katz has also founded several other health and medicine organizations, Including True Health Initiative, Diet ID, National Exchange for Weight Loss Resistance, and Turn the Tide Foundation. He has also been an advisor to Sunbasket, Better+, Fitbit, Mercy Virtual, Verywell.com, Wisewear, KIND, and Mindstream Academy.[5]

Throughout his career, Katz has published over 400 papers in scientific journals. His areas of research include nutrition, lifestyle medicine, and disease prevention.[1] He’s also overseen dozens of community and clinical trials.[9]  

From 2011 to 2015, Katz served as the editor-in-chief of the Childhood Obesity Journal. He has worked as a medical journalist, contributor, and columnist for several news publications, including ABC News, O Magazine, The Huffington Post, Forbes, US News and World Report, and The New York Times.[5]
