Worldwide, women are about 1.4 times as likely to be obese as men. But in high-income countries, the obesity gap disappears. This difference persisted in the U.S. until relatively recently. In 2000, 33.4% of American women and 27.5% of American men were obese. Over the following decade, the men gradually caught up to the women, and by 2010, obesity was equally prevalent in both genders. But the correlation between income and obesity is not uniform between the genders. Suspecting that men and women pay different prices for being obese, a group of researchers at George Washington University recently attempted to quantify the economic impact by gender. They found that obesity costs women nearly twice as much as it does men, and that the vast majority of this difference can be traced to the hit obese women take to their wages.
