Overnutrition and an inactive lifestyle contribute to many of the biggest public health challenges of the 21st century, including obesity, type 2 diabetes, cardiovascular diseases and sarcopenia. Dr. Mittendorfer’s research aims to understand the physiological mechanisms involved in driving cardiometabolic diseases and how they can be prevented or reversed by specific lifestyle interventions.
