A new survey has found that British girls were ranked the most overweight in Europe and also came at 30th place on a worldwide scale.
Some 29.2 percent of British girls aged below 19 are classified as obese or overweight, the 27th-worst record in the world, according to the University of Washington study published in Lancet.
John Newton, chief knowledge officer at the government agency Public Health England, blamed the "worrying" increase partly on fast-food culture.
"We have to look at the environment in which people are living, and the constant pressure to eat unhealthy food means things are particularly a problem for girls more than boys," he said.
"Speaking as the father of a teenage daughter, girls are particularly prone to peer pressure."
