Huntington, West Virginia, has been awarded the dubious mantle of America's fattest city, as new research found that the proportion of obese US citizens grew again last year to 27 per cent.
With almost 40 per cent of its population classed as obese, the riverside city of 50,000 led the nation in a survey by the polling company Gallup.
The fittest Americans were found in Boulder, Colorado, where just over 12 per cent of the residents of the sports-mad university community were classed as obese.
Of Americans as a whole, just 35 per cent are considered to be of normal weight, according to the survey. It showed a 1 per cent rise in obesity from 26 per cent in 2012, while a further 35 per cent were classed as overweight.
Boulder, in the foothills of the Rocky Mountains, was the only US metropolitan area to achieve an obesity rate below 15 per cent last year, according to the research.
