Intermittent fasting (or IF for short) is a hot diet trend that seems simple enough - cycle between periods of fasting and eating - for weight loss and health benefits.

But with the many IF variations (5:2, 16/8, Eat-Stop-Eat, etc) understanding the pros, cons, practicality and evidence for intermittent fasting is more complex in reality.

Join our panel of speakers, who are researching and testing IF for weight management, longevity and performance.

Don't miss this cutting edge update on intermittent fasting.

The presentations

Assoc Prof Leonie Heilbronn

BSc(Hons), PhD

Leonie  is an Australian Research Council Future Fellow at the University of Adelaide and is based at the South Australian Health and Medical Research Institute (SAHMRI), where she leads the Obesity and Metabolism laboratory.

Dr Heilbronn completed her PhD studies in 2001, and went on to research positions in the United States and in Sydney, before returning to Adelaide in 2010. Her research is at the interface between basic and clinical science, and her research goal is to reduce chronic disease risk and insulin resistance through a greater understanding of nutrition and metabolism, and mechanisms underpinning these relationships particularly in muscle and adipose tissue.

In 2014 Leanie was awarded a Diabetes Australia Research Trust (DART) grant to study the "Effects of periodic fasting on the inflammatory profile in serum and adipose tissue." She has also received an NHMRC grant to investigate period fasting and insulin sensitivity and metabolic health.

She has published more than 75 peer reviewed papers in scientific journals, and is an associate editor for Obesity Research and Clinical Practice.
