肥胖形式的超重被认为是一个人的主要危险因素，可能导致心血管疾病，肌肉骨骼状况，甚至癌症。随着体重的增加，一个人在日常生活中的能力受到阻碍，他们可能无法随着时间的推移来管理慢性疾病。在这种背景下，研究似乎表明，饮用含糖饮料，如碳酸饮料，是导致肥胖流行的原因之一。因此，澳大利亚的超重和肥胖率持续增长。澳大利亚统计局(Australian Bureau of Statistics) 2011-2012年超重和肥胖数据的详细数据显示，约三分之二的成年人患有肥胖症。在澳大利亚的成年人中，约63%的人被划分为超重或肥胖(澳大利亚健康与福利研究所，2016)。
Excessive weight in the form of obesity is considered as a major risk factor for the individual and can result in cardiovascular diseases, musculoskeletal conditions and even cancer. With the level of weight increase the person’s capabilities in daily life are hampered and they might not be able to manage chronic disorders with time. In this context, research studies seem to indicate that the consumption of sweetened beverages such as carbonated drinks are contributing to the overweight epidemic. The overweight and the obesity rates in Australia are continuing to grow because of this. Details on the overweight and obesity numbers from the Australian Bureau of Statistics for the years 2011-2012 indicates that around 2 in three adults are obese. In the Australian Adult population around 63 percent of them are classified as being either overweight or obese (Australian Institute of Health and Welfare, 2016).
In terms of costs to the country, the overweight and the obesity (high BMI) issue is seen to be the second highest contribution to the country’s economic burden of disease. The first is dietary risks and the third is smoking risks. As of 2008, with respect to obesity it was noticed that around 242,033 Australians had type 2 diabetes because of being obese, around 644,843 Australians had some form of cardiovascular disease because of being obese, around 422,274 Australians had osteoarthritis and 30,127 Australians had either a colorectal cancer or some form of breast cancer, uterine issues and more because of being obese (Australian Government, 2009). These in turn increase health care costs for the country, so there is a strong need to address the issue of obesity from a larger scale.
