Our Team

We are a group of individuals passionate about human health. We look at homo sapiens as a species in a state of crisis. The unsatisfactory way we “self-manage” is a reflection of initially inadequate education from our school system. Our poor parents don’t know the science of healthy eating so don’t know what to teach us, their children. As adults, there is a lack of incentive for us to self-educate produced by a taxpayer-funded, almost free, very high quality, emergency healthcare system in many western countries which “rescues us” when we get sick, as a result of poor eating and exercise habits. This free health care model does not punish us adequately for our poor lifestyles. This self-inflicted state of poor health results in type 2 diabetes, cardiovascular disease and Alzheimer’s dementia as we age. In the years prior to 20 when eating habits are being formed, young people can get away with eating terrible diets with little consequence other than obesity. The poor eating habits take their toll when adults are 40 plus.

At the Nutrition Science Group we enjoy being  able to continue to work with other healthcare professionals, media, employers and our education system to improve the current level of poor self-management of our health. If the public learn about self-management of diet, exercise, sleep and stress, this in turn will save governments billions of dollars spent on healthcare.

We look forward to educating through public speaking, writing, video production.  We love the work of Dr Michael Mosley, Dr Ross Walker, Dr Rangan Chatterjee, Dr Ben Bickman, Dr Peter Brukner, Dr Paul Mason, Paul Taylor and in New Zealand, Dr Glenn Davies, and Professor Grant Schofield. They are health professionals who have dedicated their careers to educating the public on preventative health. Australian Dr Rod Tayler deserves special mention. He has arguably done more than any other human on the planet to spread the word about the science of low sugar, low glycemic index, high healthy fat eating

Meet our great team

Our passion is spreading the word about low sugar, low glycemic index, high healthy fat eating in line with the now irrefutable scientific evidence showing that this approach helps the majority of people, especially if they are interested in losing weight, and dealing with type 2 diabetes either in a sub clinical or clinical form.
Dr John Stewart
Wellness Coach

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 Stewart
Wellness Coach

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.

Peter Symons
Author of Brain-Fuel Depletion

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.
