RESEARCHER PROFILE
Filmed in Adelaide, South Australia | February 2025
Professor Leonie Heilbronn is based at the South Australian Health and Medical Research Institute (SAHMRI), where she leads the Obesity and Metabolism laboratory. Her research is at the interface between basic and clinical science. She is internationally recognised for her work in nutritional modulation in humans and has made major contributions to our current understanding of mechanisms underlying conditions such as insulin resistance, particularly inflammation and lipid metabolism. She has also contributed significantly to current concepts of caloric restriction (CR), intermittent fasting (IF) and time restricted eating (TRE) in humans. She has published more than 110 peer reviewed papers in scientific journals and is an Associate Editor of Obesity, and Obesity Research and Clinical Practice.
Prof. Heilbronn is a translational investigator in obesity and diabetes research. She has a particular interest in understanding how fasting and meal timing alter nutrient signalling pathways to improve health and contributed extensively to current concepts in calorie restriction, intermittent fasting and time restricted eating. She has published more than 140 peer-reviewed manuscripts, and has a current h-index of 44. She is an Associate Editor of Obesity and the European Journal of Endocrinology. She is President of the Australia and New Zealand Obesity Society and an Associate Member of the Australian Academy of Health and Medical Science.
