Some teachers in Northern Colorado’s Poudre School District say legislation to encourage more physical activity among children won’t be enough to stop the rise of obesity. Although national health officials recommend that kids get 30 minutes of physical education each day, many schools don’t have the time or resources to meet the requirement, reports the Fort Collins Coloradoan, quoting critics who say the bill’s aims are too vague to enforce.

In the last two decades, obesity among children age six to 11 has doubled across the nation and more than tripled among teenagers, as 5280 has noted. The Colorado Children’s Campaign estimates that 76 percent of Coloradans will be overweight or obese by 2020. 

HealthDay News, meanwhile, reports that babies who gain weight too quickly during their first six months could be more likely to have problems with obesity as toddlers.
