Jessica is the Director of Ellipse Health and holds a PhD in nutrition awarded by the Faculty of Medicine and Health at the University of Sydney. Her thesis investigated the use and efficacy of low-carbohydrate diets for diabetes management, with a specific focus on type 1 diabetes. Dr Turton conducted a clinical trial in collaboration with the CSIRO using a fully online delivery model which enabled Australia-wide participation. The aim of the study was to assess the safety and effect(s) of a nutritionally adequate low-carbohydrate diet on type 1 diabetes management outcomes. The trial was completed successfully in 2022 and the results are expected to be published in 2023. Jessica has co-authored several research articles in leading scientific journals, including "An Evidence-based Approach to Developing Low-carbohydrate Diets in Type 2 Diabetes: A Systematic Review" in Diabetes, Obesity and Metabolism (read it here). Jessica was invited to speak at the American Diabetes Associated Conference in June 2020 to present the evidence for low-carbohydrate diets and nutritional ketosis in the treatment of diabetes and obesity. Jessica has a passion for working with individuals to identify the primary nutritional problems affecting their health and preventing them from reaching their goals.

Tom is a lead dietitian at Ellipse Health with several years of experience under his belt working alongside Dr Turton and many lifestyle medicine practitioners, including Dr Pran Yoganathan and Dr David Lim, in private practice. After graduating from the University of Newcastle, Tom completed additional dietetic training with Ellipse Health and was mentored by Jessica Turton who generously shared everything she knew about nutrition with him. This fuelled Tom's passion for Medical Nutrition Therapy and he has a particular interest in the application of evidence-based dietetic strategies for improving chronic pain management and inflammatory conditions, such as migraines. As a migraine sufferer himself, Tom is extremely compassionate when it comes to addressing complex health issues and understands the daily challenges involved in living with chronic pain. Prior to formally investigating the role of diet in his own health, Tom experienced up to six debilitating migraines a fortnight and it was having a major impact on his quality of life. With a targeted nutritional approach, Tom has now reduced the severity and frequency of his migraines. Tom co-authored an article with Jessica Turton on getting started with low-carbohydrate diets - you can read it here. He was also an invited speaker at the Low Carb Canberra conferences in 2020 and 2022.
