According to the Food and Agriculture Organization of the UN, 1.4 billion people are overweight -- half a billion are obese -- and America is at the top of the list of the most obese developed nation in the world -- 31.8 percent of its population and rising. That means almost 1 in every 3 people in the United States is classified as obese.
That number is expected to grow to 42 percent by 2030.
