Obesity has become a global issue and Australia is no exception. With an estimated 67% of adults (as at 2017) classified as obese, it is crucial to understand the factors contributing to this growing problem and how it can be addressed. In this article, we will dive deep into the obesity rate in Australia and what can be done to tackle this epidemic.

Definition of Obesity

Obesity is defined as having an excessive amount of body fat. A person is considered obese if their body mass index (BMI) is 30 or higher. BMI is calculated by dividing a person’s weight in kilograms by their height in meters squared. It is important to note that BMI is not a perfect indicator of health, as muscle mass and bone density can also impact a person’s BMI, but it is a commonly used tool to assess obesity.

Causes of Obesity in Australia

There are several factors that contribute to the growing rate of obesity in Australia. These include:

Unhealthy Diet

A diet high in processed foods, sugar, and unhealthy fats is a major contributor to obesity. Many people in Australia consume fast food on a regular basis, which is high in calories and low in nutrients. Additionally, portion sizes in restaurants and at home have increased, leading to overconsumption of calories.

Lack of Physical Activity

Sedentary lifestyles have become increasingly common in Australia, with many people spending long hours sitting in front of computers or televisions. This lack of physical activity combined with unhealthy eating habits has contributed to the obesity epidemic.


Obesity can also be influenced by genetics. Some people may have a higher tendency to gain weight due to their genetic makeup.

Socioeconomic Status

Studies have shown that low-income communities tend to have higher rates of obesity. This is often due to limited access to healthy food options and recreational facilities, as well as lower levels of education and awareness about healthy lifestyle choices.

Another factor is the lack of access to healthy food options in certain areas, particularly in lower-income neighborhoods. This is often referred to as “food deserts,” where fresh fruits and vegetables are not readily available and the only options are fast food and processed snacks.

Consequences of Obesity

The consequences of obesity go far beyond just appearance. Obesity can lead to a range of serious health problems, including:

Type 2 Diabetes

Obesity is a major risk factor for type 2 diabetes, a chronic condition in which the body is unable to effectively regulate blood sugar levels.

Cardiovascular Disease

Obesity can increase the risk of heart disease, stroke, and high blood pressure, which are all leading causes of death in Australia.


Studies have shown that obesity can increase the risk of several types of cancer, including breast, colon, and kidney cancer.

Joint Problems

Obesity can also lead to joint problems, such as osteoarthritis, due to the increased stress on weight-bearing joints.

Mental Health Issues

Obesity can also have a negative impact on mental health, with studies showing a link between obesity and depression.

To effectively tackle the growing problem of obesity in Australia, a multi-faceted approach is necessary. This includes:

Promoting Healthy Eating Habits

The government, healthcare providers, and educators can work together to promote healthy eating habits. This can be done by providing education about healthy food options and portion control, as well as making healthy foods more accessible and affordable.

Encouraging Physical Activity

Increasing physical activity levels can help combat obesity. This can be achieved through promoting active lifestyles, investing in recreational facilities, and encouraging physical activity in schools and the workplace.

Improving Awareness and Education

Increasing public awareness about the dangers of obesity and the importance of a healthy lifestyle is crucial. This can be achieved through education campaigns, community outreach programs, and through healthcare providers. By providing accurate and up-to-date information, people will be more informed and equipped to make healthy lifestyle choices.
