Who is the Fattest Nation in the World?

Australia could soon unseat the United States as the fattest nation in the world according to a study by Australian researchers. 


"If we ran a fat Olympics we'd be gold medal winners as the fattest people on earth at the moment," said the Institute of Preventative Cardiology’s Simon Stewart.

According to the study conducted by the Baker Heart and Diabetes Institute, about four million Australian adults, or 26% of the population, are obese. This is slightly higher than the 25% rate in the United States. The report entitled “Australia’s Future Fat Bomb,” said that 70% of men and 60% of women aged 45-65 were overweight or obese.

A total of nine million people were overweight and 123,000 were at risk of an early death over the next 20 years according to the study. The report claims Australia has overtaken the U.S. as the fattest nation per capita, but recent studies have suggested the U.S.’s obesity rate could be as high as 34%.

There are approximately 1.6 billion overweight adults in the world according to the World Health Organization. They expect that number to grow 40% in the next ten years. The United States is ranked number nine on the WHO list, with 74.1% of Americans overweight or obese. Australia was ranked number 21 on the WHO list.
