Globally, more than 425 million people are living with diabetes, accounting for 8.8% of the world population and estimated to project to 629 million (9.9%) by 2045 (International Diabetes Federation, 2017). Type 2 diabetes is responsible for 90% of all diabetes population. Without treatment and disease management, diabetes can cause serious complications such as cardiovascular disease, blindness, kidney failure, amputations and premature death. Approximately, AUD1,088 billion annually has spent on the healthcare costs of diabetes (NCD Risk Factor Collaboration, 2016) which means diabetes corresponds to one in every eight dollars of healthcare costs (International Diabetes Federation, 2017). The WHO has recommended four simple and effective strategies to prevent type 2 diabetes and its complications, including 1) achieve and maintain a healthy body weight; 2) be physically active; 3) eat a healthy diet, low sugar and saturated fat intake; and 4) avoid tobacco use (World Health Organisation, 2017).
