What is Obesity?

Obesity means having too much body fat. It is not the same as overweight, which means weighing too much. Obesity is becoming much more common in childhood. Most often, it begins between the ages of 5 and 6 and in adolescence.

The Cause of Obesity

Risks of Obesity

Obesity increases the risk of many diseases. Adults with a body mass index (BMI) of 30 or greater are classified as obese, but different measures are used for children and teenagers. Chronic conditions and diseases associated with obesity include diabetes, high blood pressure, atherosclerosis, cardiovascular disease, stroke, some cancers and lack of sleep.

Obesity rates in Australia have more than doubled over the past 20 years. Australia is now ranked as one of the fattest developed nations. Around 37 percent of Australians are overweight and 25 percent are obese. Overweight and obesity is more common in men than women (68 percent versus 55 per cent) and in people aged between 65 and 74 years.

Why do people become Obese?

People become obese for a lot of reasons, including:

  • People are eating much more than they used to
  • Not sleeping enough, risks of becoming obese doubles
  • Poorly balanced diets and the lack of physical exercise are key factors in the increase of obesity

Causes of Obesity

Eating an unhealthy diet and lack of exercise are the main causes of obesity. Fatty foods, sweet foods and sugary drinks can cause weight gain if you eat or drink them often. This is because they contain lots of calories and sugar. Large portion sizes can increase your chances of becoming obese.

Causes of Obesity for Children

When children eat more than they need, their bodies store the extra calories in fat cells to use for energy later. If this continues over time, and their bodies don't need this stored energy, they develop more fat cells and may develop obesity.

No single factor or behaviour causes obesity. Obesity is caused by many things, including a person’s habit, lifestyle, and environment. Genetics and some medical conditions also increase a person’s chances of becoming obese.

Causes of Obesity for Adults

In adults, the diagnosis of obesity is most commonly made using BMI levels. BMI is calculated as weight in kilograms divided by height in metres squared. As a general rule, an ideal BMI is 20 to 25.
