Almost a third of the world population is now fat, and no country has been able to curb obesity rates in the last three decades, according to a new global analysis released Thursday May 29, 2014, led by Christopher Murray of the Institute for Health Metrics and Evaluation at the University of Washington, USA, and paid for by the Bill & Melinda Gates Foundation. Researchers reviewed more than 1,700 studies covering 188 countries covering over three decades and found more than 2 billion people worldwide classified as overweight or obese. The highest rates of obesity were found in the Middle East and North Africa, with the U.S. having about 13 percent of the world's fat population. (AP Photo/Mark Lennihan, FILE)
