Based on a 2011 - 2012 survey by the Australian Bureau of Statistics, the number of overweight and obese Australian adults has continued to rise to 63 per cent from 61 per cent in 2007 - 2008 and 56 per cent in 1995.


Overweight is generally defined as having more body fat than is optimally healthy


Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems.

In 2010, the Australian Bureau of Statistics estimated that more than 4.3 million Australians, roughly one in four, were obese.

The average Australian woman weighed 62.6 kilograms in 1989. Nowadays, the average is approximately 70.1 kilograms – a difference of 7.5 kilograms.

For men, the difference is even more alarming. In 1989, the average Australian man weighed 77.4 kilograms. That has now risen to approximately 86.1 kilograms – a difference of 8.7 kilograms.

Initial results from the 2011 - 2012 health survey, released by the Australian Bureau of Statistics, show 63 per cent of adults are overweight (35 per cent) or obese (28 per cent). The figure was up from 61 per cent in 2007 - 2008, an increase which is very concerning.


Excessive body weight is associated with various diseases, particularly cardiovascular diseases, diabetes mellitus type 2, obstructive sleep apnea, certain types of cancer, osteoarthritis and asthma. As a result, obesity has been found to reduce life expectancy.


Numerous health articles have been written about the various benefits of weight loss. Below are a few examples of how a 10 kilogram weight loss can have a significant positive impact on one’s condition:

  • Diabetes – 50% fall in fasting glucose
  • Blood Pressure – 10mmHg fall in Systolic BP and 20mmHg fall in Diastolic BP
  • Blood Lipids – 10% fall in total cholesterol; 15% fall in LDL; 30% fall in triglycerides; 8% increase in HDL
  • Blood Clotting Indices – reduced red cell aggregability; improved fibrinolytic capacity
  • Physical Complications – reduced back and joint pain; improved lung function; reduced breathlessness; reduced frequency of sleep apnea
  • Mortality –  >20% fall in total mortality; >30% fall in diabetes related deaths; fall in obesity related cancer deaths
