America's waistline continues to expand, according to a study published on May 29 in The Lancet.
The obesity epidemic remains the biggest public health issue facing the country, and despite awareness of the need to get in shape, more than a third of the country is now obese.
But it's not just America — much of the developed world has seen similar increases, according to the study.
China and India (No.2 and No.3 on the list) together make up 15 percent of the world’s obese population.
Worldwide, the number of overweight and obese people increased from 857 million in 1980 to 2.1 billion in 2013 — an increase of more than 145 percent.
The 7 other countries on the top 10 list are Russia, Brazil, Mexico, Egypt, Germany, Pakistan and Indonesia.
