The biggest increases in excess weight gain are from childhood to early adulthood. Many Australians consume more energy than they need through unhealthy diets that are high in sugar, saturated and/or trans fats and alcohol.
The rise in obesity has been attributed to poor eating habits in the country closely related to the availability of fast food since the 1970s, sedentary lifestyles and a decrease in the labour workforce.
Based on the latest available data, of adults aged 18 and over (ABS 2018e): Two in 3 (67%) are living with overweight or obesity. This is approximately 12.5 million adults.
Factors that may cause children to become overweight and obese include: Food choices – these include choosing high fat and sugary foods instead of healthier options. Lack of physical activity – Australian children are less active than they were in the past.
Lack of exercise is also a major culprit in the obesity epidemic. It's been decades since most Americans worked in fields and on factory floors, a far greater majority of us are sitting throughout our workday. This means less exercise each day.
As the economies of developing coun- tries continue to improve, the risk of becoming obese increases across all socio- economic classes as a result of improved access to food, decreased physical activity, and the consumption of “western” diets (Popkin, 1993; Cavalli-Sforza et al., 1996; Drewnowski and Popkin, 1997).
The National Obesity Strategy is a 10-year framework for action to prevent, reduce, and treat, overweight and obesity in Australia. It focuses on prevention, but also includes actions to better support Australians who are living with overweight or obesity, to live their healthiest lives.
People who have obesity, compared to those with a healthy weight, are at increased risk for many serious diseases and health conditions. In addition, obesity and its associated health problems have a significant economic impact on the US health care system. Obesity also affects military readiness.
Overweight and obesity are major risk factors for a number of chronic diseases, including cardiovascular diseases such as heart disease and stroke, which are the leading causes of death worldwide.
For all measures of overweight and obesity, men had higher rates than women did: 75% of men and 60% of women are living with overweight or obesity. 42% of men and 30% of women are living with overweight but not obesity.
According to data from the World Health Organization (WHO), the most obese countries are primarily located in the Pacific and the Middle East. The Pacific island nations of Nauru, Cook Islands, and Palau have the highest rates of obesity, with over 30% of their populations being classified as obese.
Obesity occurs when energy intake (food) is substantially higher than energy expenditure (in particular physical activity). The cause of the obesity epidemic must therefore be due to either an increase in energy intake from food or a decrease in physical activity (or a combination).
The high caloric density and trans-fat content of fast food are only some of the factors contributing to the obesity epidemic. In the past 30 years, the portion sizes of many foods have increased, leading to increased energy intake.
Choosing healthier foods (whole grains, fruits and vegetables, healthy fats and protein sources) and beverages. Limiting unhealthy foods (refined grains and sweets, potatoes, red meat, processed meat) and beverages (sugary drinks) Increasing physical activity. Limiting television time, screen time, and other “sit time”
The High Cost of Excess Weight
No less real are the social and emotional effects of obesity, including discrimination, lower wages, lower quality of life and a likely susceptibility to depression. Read more: health risks and why being overweight does not decrease mortality.
Obesity can lead to many other health problems. Some of these are heart disease, type 2 diabetes, and joint problems. Obesity can be prevented with healthy lifestyle choices like being more physically active and eating more fruits and vegetables.
It's a medical problem that increases the risk of other diseases and health problems, such as heart disease, diabetes, high blood pressure and certain cancers. There are many reasons why some people have difficulty losing weight.
Media Release - 16 November 2020. Aussie men are the second most obese in OECD countries - Aussie men have the second highest rates of obesity (32%) among 23 OECD countries, behind the USA (38%). Aussie women fared better than men but are still obese at a higher rate than the OECD average.
Tamworth was given the unflattering title of fattest town in Australia back in 2020, when the Australian Bureau of Statistics found that 61.2 per cent of residents were considered obese, compared to 31.3 per cent nationally.
Nutrient transmission (change in diet) is the primary cause of the obesity epidemic in the Pacific Islands, with a high amount of imported foods high in salt and fat content grow.
The obesity epidemic started in the 1980s but poor monitoring systems meant the rise in obesity prevalence initially went undetected. In the 1990s, experts started advocating for government action; however, it was the rapid increase in media reports on obesity in the early 2000s which created the pressure for action.
The report indicated the financial burden of obesity in Australia is estimated to be $11.8 billion. Those figures consist of $5.4 billion in direct health costs and $6.4 billion in indirect costs.
