The number of obese women in America has grown to outnumber men.
A decade ago, both genders' obesity rates were roughly the same, at about 35 percent of Americans for each.
But a new study published in the Journal of the American Medical Association says while men's obesity rate stayed at 35 percent, by 2014, women's had climbed to 40 percent.
The increase in obesity for women, or even the lack of a decrease for men, could be troubling, considering how much money has been spent on campaigns against it.
A different JAMA article notes hundreds of millions of dollars have gone toward obesity research and drug development.
And the Harvard School of Public Health says in 2005 –– even when the women's rate was lower –– the U.S. spent $190 billion on health care expenses stemming from obesity.
One limit to the prevalence study we first mentioned could be what's counted as obese.
The government data used height and weight proportions to calculate participants' body mass indexes –– not their fat content directly.
