The British BBC documentary above originally aired back in 2008. At the time, one in four preschool children in the UK were overweight or obese, closely matching childhood obesity rates in the United States.

According to the latest statistics, 30 percent of British children between the ages of two and 15 are now overweight or obese.

Similarly, in the US, more than one-third of children and adolescents are overweight or obese. Eighteen percent of American children between the ages of six and 11 are in the obese category-up from seven percent in 1980. Five percent of American children are “severely obese,” which puts them at grave risk for chronic diseases typically reserved for adults, such as heart- and liver disease.
