The Australian and New Zealand Obesity Society (formally known as the Australasian Society for the Study of Obesity or ASSO) was established in 1991.

ANZOS is a scientific organisation of medical practitioners, dietitians, scientists and other health care professionals interested in obesity research, treatment or public health initiatives directed at the prevention of obesity.

The Society has over 250 members throughout Australia, New Zealand and the Pacific Region.

Letter to Ministers


On November 24, 2017 Ministers across the nation had an opportunity to discuss and support a recommendation that, where sugars are added as a separate ingredient to a food product, information must be provided on the label of the product to identify added sugars.  This is the letter we sent to all Ministers attending the meeting.

Tipping the Scales

Over the past two years the Obesity Policy Coalition and The Global Obesity Centre, Deakin University, have convened an expert advisory group of public health professionals representing a range of organisations. Through this process we have developed the agreed key components of a national obesity prevention strategy for Australia. Further, these priority actions have been endorsed by a range of academic, public health, consumer and other groups. This consensus delivers a rigorous and evidence based agenda to our Federal Government and establishes the key elements to include in a national strategy as well as the basis for an ongoing dialogue about the best ways to addresses the obesity epidemic.
