Dr Evelyn Parr is a senior research fellow with research interests in reducing obesity through changes in body composition and the management of blood glucose in response to exercise and nutritional interventions. Evelyn’s current research portfolio in the Exercise and Nutrition Research Program involves work regarding manipulating the timing and composition of nutritional intake and exercise on the development of type 2 diabetes in conjunction with overweight/obesity. Evelyn completed her undergraduate Physical Education and Science degrees at the University of Otago in Dunedin, New Zealand. She then completed a research masters in Exercise Metabolism investigating the effects of exercising in the cold on metabolism in female cyclists. A move to Australia to work with Prof Hawley, originally at RMIT and then at ACU, enabled Evelyn to run a large-scale weight loss exercise and diet intervention, aimed at preventing the loss of skeletal muscle mass in older adults, as a part of her PhD studies. Evelyn was awarded her PhD in May of 2016, titled “Exercise and nutrient interactions: Effects on skeletal muscle and body fat mass”. As a keen cyclist, Evelyn’s research interests centre around optimizing and enabling the best prescription of exercise to individuals with a previous history of not exercising. Evelyn’s major projects, in collaboration with Prof Hawley, Dr Brooke Devlin (La Trobe) and A/Prof Leah Brennan (La Trobe) are investigating the effects of time restricted eating in the management of glycaemic control for individuals with type 2 diabetes. In a larger, multi-centre trial with the University of Adelaide, the team are also investigating the effects of time restricted eating to reduce the risk of type 2 diabetes.
