TUCSON (KGUN9-TV)-- According to a new study by the CDC, many kids who are overweight, don't see themselves that way. This study spanned from 2005 to 2012. Almost a third of children and teens between the ages of 8 and 15 put themselves in the wrong weight category. That's a little more than 9 million young people. More than three quarters of overweight young people and more than 40 percent of obese kids didn't realize they had a weight problem.The issue? If you don't see yourself having a problem, then you can't change to a more healthy lifestyle. Being overweight or obese compromises a child's health, increasing their risk for cardiovascular disease, type 2 diabetes and other health issues.
