Obesity has become a major problem in the U.S. A growing number of adults and children are living unhealthy lifestyles. Carrying around extra weight can also lead to a variety of other health conditions.

Those who are overweight are more likely to develop high blood pressure and type 2 diabetes, for example. Both conditions are costly to the healthcare system and can be avoided in most cases.

Childhood obesity is particularly rampant in Georgia, which has the second-highest rate in the country. Avoiding unhealthy foods and watching portion sizes can help people lose weight.

Child Wellness at Children's Hospital medical director Dr. Stephanie Walsh says combating obesity requires everyone's efforts.

"The crisis of childhood obesity is the responsibility of every Georgia citizen," says Walsh. "As a society, we need to take ownership and act immediately on this issue for the sake of the future health of Georgia's population."

According to the 2007-2008 National Health and Nutrition Examination Survey, it's estimated that nearly 17 percent of of those between the ages of 2 and 19 are obese. Action will need to be taken to reduce the trend of obesity.
