KAMILAROI man Ray Kelly says the fact a reversible disease like type 2 diabetes is growing shows the health system needs to change.
In recent years, Mr Kelly has been visiting outback and disadvantaged metro communities, as well as corporate settings, making huge changes to individuals' health with a simplified approach to tackling diabetes.
"It is based around eating fresh, unprocessed foods and light exercise so it's something anyone can do" Mr Kelly said.
"I am currently working toward a PhD in reversing diabetes."
The program is now headed for Coledale, Quirindi, Werris Creek and Walhallow following successful runs in areas including Bourke and Walgett.
He said one person in Bourke was able to drastically reduce their insulin intake in a matter of weeks after being on four-to-five injections a day for 20 years, under the "Too Deadly for Diabetes" program.
It has been provided through Aboriginal health services giving patients affordable diet and exercise regimes.
Mr Kelly is calling for Aboriginal people in the region to sign for the program which gets under way in the coming weeks.
"In the past, diabetes programs have been teaching people to live with the disease," he said.
"We turn it around and what we do teach is how to manage blood sugars.
"It's a reversible disease which is growing, but less than 50 per cent of all diabetics can achieve ideal blood sugars ... that means it's not the patients, but the system which needs changing the in medical centres."
Mr Kelly's diabetes program targets the reduction of fat surrounding the liver and pancreas.
The Primary Health Network has provided funding for the Walhallow program, while University of New England Professor Kim Usher will be completing research on the outcomes of the program.
West Tamworth, including Coledale, has some of the highest rates of diabetes in Australia, according to national health trackers.
