Studies show that more kids are becoming obese these days due to more emphasis on video games, TVs, and computers, rather than actually exercising. Big Macs only add to the problem. Leonard Epstein of the State University of New York and team came up with a monitoring device that cuts time in half, resulting in overweight kids being forced to do something else that would burn those calories. After 2 years, the study found that kids who were restricted by 17.5 hours a week ended up with lower BMIs. We think this would be a good idea for some of the adults we know.
