World Obesity Day: Which countries have the biggest weight problem?

Read the text.

More than 603 million adults and 107 million children (out of a global population of around 7.5 billion) are obese, according to a report published earlier this year from the Institute of Health Metrics and Evaluation, based at the University of Washington in Seattle. That represents around five per cent of all children and 12 per cent of all adults. But which nations have the highest levels of obesity?

Telegraph Travel took data from the CIA's World Factbook and, contrary to what some may believe, it is not the US that tops the chart, but rather American Samoa - an unincorporated territory of the US in the South Pacific - where a whopping 74.6 per cent are considered to be obese.

A slew of other South Pacific nations follow, including Nauru, Tonga, Samoa, Palau and Kiribati. In fact, Kuwait is the only country outside the region to feature in the top 10. There is a clear obesity problem in the South Pacific, with the weight of adults is increasing at four times the global average. Some have claimed the islanders are genetically predisposed to putting on weight, while a 2014 report suggested that colonial settlers, who taught them Western ways of eating - frying fish, for example, rather than eating it raw - are to blame.
