Dr. John Stewart after being diagnosed as pre-diabetic, decided to take charge of his life by starting to eat healthy. He has been rewarded with now normal fasting blood glucose values and a Body Mass Index of 22. He is an advocate of intermittent fasting and finds his periods in ketosis bring him improved mental clarity. He was a sweet toothed, chocaholic lover of high glycemic index foods (eg. bread, rice, pasta, potato) which made the transition to a healthy diet quite difficult for him. His family had a history of diabetes which made him even more determined to change his eating habits. He has spent thousands of hours looking at the latest nutrition research and interacting with scientists and healthcare workers. His training in nutrition, physiology, pathology, microbiology, and pharmacology as a veterinarian has allowed him an appreciation of cross-species differences between humans and other mammals. He contributes his time to the nutrition science group unpaid.

Katherine is a warrior for healthy eating, exercise and meditation. She is training to run her fourth half marathon this year. She is a registered occupational therapist. She finished dux of her class graduating with first class honours. She is a showjumping rider who as a teenager represented Australia at the World children’s showjumping championships in the USA. Two significant injuries happened while this young rider was looking like she might be a potential Olympian. This setback taught her to cope with disappointment and helped her develop the resilience she exhibits today. In addition to riding horses, she runs, skis, swims, plays tennis, table tennis and works out at the Gymnasium. She is also very interested in mental health practices like meditation. She is very good at enthusing those around her. Katherine “walks the talk” re her low carb high healthy fat eating. She is a great role model and admired by her friends for overcoming the setbacks she has faced.

In 2001, Peter Symons recovered well, physically, from his third brain haemorrhage, and second brain surgery. That was the easy part – a much bigger challenge soon presented itself.

He spent an horrendous six months suffering emotionally…to the point of suicidality; before reluctantly seeking help.

Peter Symons, an equine veterinarian diagnosed with depression despite never feeling depressed; developed the Brain-Fuel depletion model that, finally, makes sense of this confusing condition. He then wrote the book "Brain-Fuel Depletion" along side with Dr Clyde Jumeaux to give people great relief and understanding on anxiety and depression.

Olaf Sorensen runs Metabolic Performance from his home base in Glenelg, South Australia, 5045. He focuses on the benefits of eating a low-carb, high-fat diet, regular fasting, being in ketosis and combining it all with high-intensity exercise. His work with clients is the fruit of his years of long-distance running during which he learnt a valuable lesson which can be applied to everyday life: we gain an abundance of energy by improving our physical fitness. Olaf has been self experimenting with the carnivore diet since 2017.

Steven Hamley is a PhD candidate (doctor of philosophy) at Deakin University. He is nearing the end of this 4 year commitment. His research project is on the pathophysiology of insulin resistance (pathophysiology is the mechanism by which the disease develops). He has published 8 scientific articles in peer-reviewed journals on topics related to physiology, metabolism, and insulin resistance, as well as a meta-analysis on saturated fat and heart disease. He has been a presenter at conferences run in Australia and overseas. He is highly valued by The Nutrition Science Group advisory board as a consultant to the Nutrition Science Group. He is one of the “go to” persons when a colleague meets a perplexing issue. His peers regard him as a “rising star” on the Australian landscape as a clear thinker and scientist (Think Ash Barty "rising star" in Australian tennis over the last couple of years).

For his honours thesis, his research group was the first to demonstrate that only 1 week of a simple diet switch completely reversed pre-diabetes in mice. Steven’s honours thesis received the highest mark in the school of exercise and nutrition science, faculty of health, earning him two student prizes, and a PhD scholarship.

He was the runner up New Zealand GP of the year in February 2020. He has done great work in the Taupo population assisting particularly the Maori community with reversing type 2 Diabetes and obesity. He teaches part time in the "PreKure" health coaching program.
