James McCarter, MD, PhD. is a researcher and author of over 60 scientific publications and patents. He recently led research and clinical operations for San Francisco-based Virta Health, a nationwide medical provider that delivers the first clinically-proven treatment to safely and sustainably reverse type 2 diabetes without medications or surgery. Dr. McCarter recently directed the Virta - Indiana University Health clinical trial demonstrating reversal of diabetes using nutritional ketosis and guided behavior change. This trial has resulted in changes to the American Diabetes Association Standards of Care and consensus statement on nutrition in 2019, reflecting the benefit of low-carbohydrate diets. 

In this podcast, James discusses the results that have emerged from this research and the incredible outcomes Virta is demonstrating in helping people reverse their type-2 diabetes and improve cardiac risk markers. He also talks about the five facets of treatment behind Virta’s success, and the business model they employ to make treatment more widely available. 

Dr McCarter recently spoke at the AACE (American Association of Clinical Endocrinology) meeting in Kansas City on ketosis for T2D. These slides provide nice visuals for all of the Virta-IUH trial outcomes as well as background information.
