The American obesity epidemic 1989 – 2010.

"Here is the obesity prevalence in the USA in 1989, as the modern obesity epidemic was just getting started. A few years earlier the fear of fat had gripped the nation, and eating carbohydrates instead was the solution.

Two short decades later, in 2009, the official obesity statistics had changed beyond all recognition. And every year there is a new record. Just recently the numbers for 2010 was released. Do you want to see them?"

Very much the same in the UK !
