About

The Obesity Evidence Hub’s objective is to identify, analyse and synthesise the evidence on obesity.

About the Obesity Evidence Hub

The Obesity Evidence Hub is a joint project resulting from a partnership between the Cancer Council Victoria, the Bupa Health Foundation and the Food for Health Alliance. It is a foundational component to the Obesity Collective, a modern movement to drive action on important obesity initiatives in Australia.

The Obesity Evidence Hub’s objective is to identify, analyse and synthesise the evidence on obesity. By presenting the evidence base, our goal is to provide the platform for future policy development in Australia.

The Obesity Evidence Hub covers obesity trends; health impacts; prevention; environmental influences; and treatment. The hub is a constantly evolving platform, to be refreshed as new data becomes available and trends emerge over time.

Our approach

The information on this website draws on the best available evidence from the academic literature, including systematic reviews and meta-analyses where available. The most current data on rates of overweight and obesity and diet and exercise has been sourced from government agencies including the Australian Institute of Health and Welfare and the Australian Bureau of Statistics.

The Hub also uses a range of other sources including key reports by policy thinktanks and health groups; submissions to government inquiries; and reports from reputable media outlets. The information has been clearly referenced so that users of the Hub can seek out more information from source documents where this is useful for their purposes.

Original content for the Hub was overseen by Food for Health Alliance Executive Manager Jane Martin; and Academic Director of the Charles Perkins Centre at the University of Sydney Professor Stephen Simpson. With the exception of the Treatment section, content was mostly written by Cancer Council Victoria research and policy consultant Kate Hagan with input from the topic experts listed below. The Hub was updated between 2022 and 2025 with new data and inclusions; these authors are indicated below.
