The numbers are startling: 34% of Americans are obese - not just overweight, but obese. That number is expected to grow to 42% by the year 2030.
A new book and documentary are working to issue a wake up call. It's called "Weight of the Nation" with the four-part series airing tonight on HBO.
This morning, HBO Documentary Films vice president John Hoffman and the Institute of Medidine's Dr. Judity Salerno explain why obesity is not a 'failure of personal will' as some believe, but a crisis where everyone has to take responsibility to solve it.
