Dr. Kevin Hall, PhD is Senior Chief of the Integrative Physiology Section of the Laboratory of Biological Modeling at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). His laboratory investigates how metabolism and the brain adapt in response to a variety of interventions to diet and physical activity. They carry out studies to better understand the complex mechanisms regulating macronutrient metabolism, body composition, and energy expenditure. Recently Dr. Hall was lead author on a study titled 'Effect of a plant-based, low-fat diet versus an animal-based, ketogenic diet on ad libitum energy intake', which was published in Nature Medicine in early 2021.
