Julie Manasseh
Dr Julie Manasseh - Vice President
She graduated from the University of Western Australia in 1988 with a Bachelor of Medicine and Bachelor of Surgery. She has had extensive experience across the breadth of general practice including women’s health and mental health. She developed an interest in obesity management some years ago, when she realised that over the years, more and more patients were presenting with medical complications related to obesity. She wanted to be able to help her patients address the root cause of their obesity-related complications like diabetes and hypertension, which was their excess weight, rather than just prescribing them medications to treat the complications.
Hence she sought to educate herself further on obesity management. She gained a postgraduate diploma in obesity and weight management with distinction from the University of South Wales in 2017. She has completed SCOPE accreditation through the World Obesity Federation and the Horizon obesity management programme. Her passion is to help to increase education of GPs and specialists in the area of obesity management. She founded the WA Obesity Special Interest Group in 2023 whose members span all healthcare disciplines including GPs, bariatric surgeons and allied health professionals such as dieticians and exercise physiologists. The group holds meetings every quarter to discuss educational obesity topics and acts as a network of professionals for referrals for our patients.
She aims to provide a private multidisciplinary obesity management clinic in Perth which will individualise the management plan according to the patient’s needs, and utilise healthcare professionals who work collaboratively to best suit each patient’s needs.

Within the fitness industry, he has had a great deal of success in the area of weight loss. He was employed as a trainer in the first 2 seasons of The Biggest Loser Australia, where he was given 1 contestant each year. He achieved a perfect record with both contestants winning the competition in consecutive years. He has also written 2 books on weight loss, titled “Winners Do What Losers Don’t” (New Holland, 2008), and “Full Plate, Less Weight” (New Holland, 2014). He has also had input into many publications.
Mr Kelly is award winning Exercise Physiologist, more recently winning the ESSA Exercise Physiologist of the Year (2019). He holds numerous advisory positions and teaching positions including as the Chairperson of the Indigenous Advisory Committee for the Australian Centre for Accelerating Diabetes Innovations (ACADI), the Expert Reference Group for the Australian Diabetes Educators Association, National Advisory Group for Exercise and Sports Science Australia (ESSA), NSW Indigenous Projects Officer (ESSA), and the Advisory Group for the Diabetes and Endocrine Network (Agency for Clinical Innovation).

In the 3-part series Ray presented the research on remission of type 2 diabetes and supported 8 Australians as they turned their health around.
Ray’s passion is Indigenous chronic disease and this led him to develop the Too Deadly for Diabetes is a lifestyle program. It is provided primarily through Aboriginal medical services in rural and remote NSW. Mr Kelly engages with the local Indigenous community and health care providers to identify obstacles and design strategies. This hasImage removed by sender.Ray Parliament_DSF1704 (1).jpg proven effective with each location witnessing a major improvement in clinical outcomes. An independent study was completed on the program in Western Sydney where participants achieved an average weight loss of 7.5kg and a reduction in HbA1c of 1.7%. In his program in Coonamble, patients have lost over 2,200kg in total in the first 2 years of the program.
In particular, the Too Deadly for Diabetes program is provided in many areas where the health outcomes for those with type 2 diabetes is often poor. This leads to an increasing number of patients suffering from complications with their feet, kidneys, eyes and cardiovascular system. As participants often improve their food intake, increase physical activity and reduce HbA1c, the previous issues around the co-morbidities are significantly reduced.
