Obesity is no longer considered a cosmetic issue due to eating too much. The World Health Organisation (W.H.O) from 2013 recognizes obesity as a chronic progressive disease resulting from multiple environmental and genetic factors.
Obesity is defined as a disease in which fat has accumulated to the extent that health is impaired.
Obesity is commonly measured by body mass index (BMI), which calculates the relationship of weight to height. An adult with a BMI of 30 or more is considered obese.
An increasing number of Australians are at high risk of serious diseases and premature death because of excess body weight or obesity. More than two thirds of Australian adults are either overweight or obese and 23 per cent of children aged 2 – 16 years are either overweight or obese.
Obesity substantially contributes to preventable, non-communicable diseases, shortened life-expectancy and impaired quality of life. Obesity is a major risk factor for chronic conditions such as type 2 diabetes, heart disease, hypertension, stroke, musculoskeletal disorders and impaired psychosocial functioning. Obesity is now challenging smoking as the major cause of potentially preventable death in Australia
