On this special edition of CBS' Sunday Morning, Charles Osgood told us stories about America's obsession with being fat. The obesity epidemic is a heavy subject (ha, get it?), that is costly and effects nearly a third of American adults.

America is 4.6 billion pounds overweight, and over $147 billion is spent yearly on health problems related to obesity. People spend $60 billion dollars a year on dieting, and places like the Duke Diet and Fitness Center run about $8,000 for a one month stay. On top of this, the Center for Disease Control estimates that one-third of American adults are overwieight, and an additional third is obese.

Mo Rocca visited dietician Kathy Isoldi in New York City to find out why he wasn't effortlessly skinny anymore. Despite looking like a reasonably normal human, it turns out he is practically overweight.

In a nation that is so obsessed with being thin, the health aspect of being overweight or obese is often lost in the images of waif models in glossy magazines. Despite hard facts like the ones cited above, things like different standards of beauty and movements of acceptance worldwide make this apparent epidemic almost hard to believe.

The best and most ironic part of watching this show-a commercial for CBS' new comedy about an overweight couple, called Mike and Molly, that boasts a tagline of "More to Love".
