In 20 years, four out of ten American adults will be overweight, according to a recent study published by the U.S. Centers for Disease Control. Even today more than 78 million U.S. adults are obese.
Faced with these staggering figures, the U.S. Surgeon General, the nation’s leading spokesman on matters of public health, says Americans need to be more active. To set an example, Surgeon General Regina Benjamin went for a walk this week. Lots of other people went along — including VOA’s Mariama Diallo.
