At least 20 per cent of adults are obese in every state of America, according to new figures from the Centers for Disease Control and Prevention.
In four states – Alabama, Louisiana, Mississippi, and West Virginia – more than 35 per cent of residents are morbidly overweight.
And 21 states have a rate between 30 and 35 per cent.
The figures, released on Thursday, are a damning sign that public health efforts to improve nutrition and fitness are barely scratching the surface of the problem.
At least 20 per cent of adults are obese in every state of America, this new CDC map reveals
Colorado had the lowest rate, which was a staggeringly high 20.2 per cent.
The highest figure was recorded in Louisiana, where 36.2 per cent of adults are obese.
The data came from a series of telephone interviews conducted from 2013 to 2015, asking people their height and weight to calculate their body-mass index (BMI).
According to the CDC, a BMI above 30.0 is classed as obese.
Breaking down the data into racial groups, the researchers found stark differences.
More than 38 per cent of non-Hispanic black adults were classed as obese.
In at least 34 states, more than 35 per cent of the non-Hispanic black population is obese.
Around 32 per cent of Hispanic adults are obese, and 27 per cent of white adults are obese.
There was some good news: obesity figures decreased in four states (Minnesota, Montana, New York and Ohio) between 2014 and 2015.

It is the first time in 10 years that any states have seen a decline in obesity rates.
However, the number of obese adults went up in Kansas and Kentucky.
And the rest maintained their staggeringly high rates with little difference either way.
Public health officials are urging the nation to look at Minnesota, Montana, New York and Ohio as examples in a bid to combat the obesity epidemic.
The government currently pours as much as $ 210 billion a year into health services to treat obesity-related diseases like diabetes and heart disease.
As the number of office-bound stationary jobs increases, and the population ages, officials warn the situation is only going to get worse unless we combat diet and fitness culture.
