As our children head off to school each day, backpacks aren't the only things weighing them down.
Recent studies show that obesity in children has more then doubled in the last decade.
So the challenge now is reversing this trend. When they come to the U.S., that same group ends up gaining weight. But we're seeing it now in teenagers. The body is actually making more insulin then normal. But something about having excess fat tissue makes the insulin not function as well in doing its job of getting that sugar out of the bloodstream and into cells.
