Overview

I am a general internal medicine doctor, obesity medicine specialist, and clinical researcher. I have focused my career on the research and management of obesity and its related health issues. I became interested in weight management during my training because I recognized I could treat my patients’ health problems more effectively, and with less medication and fewer devices and procedures, if I could help them manage their weight. I grew up in Durham and came back after residency to join Duke Health. In 2015, I became Director of the former Duke Diet and Fitness Center, now called Duke Lifestyle and Weight Management Center, and certified in obesity medicine. Duke Lifestyle and Weight Management is a multidisciplinary center with experts in medicine, nutrition, fitness, and behavior who are focused on helping patients improve their health via lifestyle change and weight loss using a patient-centered, comprehensive approach.

Dr. Yancy is rated as a Distinguished provider by MediFind in the treatment of Obesity. His top areas of expertise are Obesity, Type 2 Diabetes (T2D), Maturity Onset Diabetes of the Young, and Obesity in Children.

His clinical research consists of co-authoring 132 peer reviewed articles. MediFind looks at clinical research from the past 15 years. In particular, he has co-authored 60 articles in the study of Obesity.
