Obesity is a chronic health condition where a person has too much body fat, which can negatively affect their health and wellbeing. In Australia, obesity is commonly defined using the Body Mass Index (BMI), where a BMI of 30 or more is considered obese. While BMI doesn’t measure body fat directly, it’s a useful tool to identify those at higher risk of health issues related to excess weight.
Obesity is more than just a number, it’s a complex condition influenced by lifestyle, environment, genetics, and mental health. It develops over time when energy intake (through food and drinks) consistently exceeds energy output (via physical activity and body functions). It’s not just about “eating too much” or “exercising too little”, many people face barriers like limited access to healthy food, lack of time or facilities for exercise, or underlying medical conditions.
Why Does Obesity Matter?
Obesity can increase the risk of developing a wide range of serious health conditions, including:
Potential Health Risks
● Type 2 diabetes: Obesity is the leading risk factor.
● Heart disease: Excess fat can raise blood pressure and cholesterol.
● Certain cancers: Including breast, bowel, and kidney cancers.
● Sleep apnoea: Interrupted breathing during sleep.
● Osteoarthritis: Extra weight puts strain on joints.
● Mental health challenges: Such as depression and low self-esteem.
In Australia, over two-thirds of adults and one in four children are overweight or obese. It’s a growing public health concern, especially in rural communities with limited access to healthcare, fresh produce, and exercise facilities.
