What is obesity?
“Obesity” is a medical term used to describe extra body fat that affects a person’s health. Just like other health conditions, obesity is not a personal judgment or a reflection of someone’s character. Obesity is a chronic, relapsing condition, with strong social, genetic, biological, historical, and environmental influences. It is not only about personal responsibility and behaviour change. Today, weight stigma and bias remain key barriers to collectively understanding and addressing obesity.
Our work
The Obesity Collective was established to transform the way Australia thinks, acts and speaks about obesity. There is growing recognition that obesity is a systems and societal challenge that is misunderstood and we need to do more about it for the health and wellbeing of Australians. We work to create the network for collaboration, change the narrative around obesity and advocate for action to create healthier environments and better support from the health system.
