All those anti-obesity campaigns are working—for teens anyway. Teenagers are exercising more and eating less sugar and more vegetables, reveals a study published Monday in the journal Pediatrics. But teens are still getting less than the recommended amount of exercise, logging in an average of an hour of exercise fewer than five days a week. What’s more, they spend an average of two hours a day watching television or chatting online. Younger children came out the best in the study, with the highest levels of exercise and fruit and vegetable consumption—but it appears their habits deteriorated as they got to be teenagers. Boys overall reported more physical activity than girls, but they watched more television, played more videogames, and consumed fewer vegetables.
