Childhood obesity is a serious concern for Americans. It’s so serious that First Lady Michelle Obama led a major public health campaign to fight it through exercise and healthy eating.

But despite these efforts, childhood obesity is still a problem, affecting nearly 13 million children and teens, according to figures from the Centers for Disease Control.

The statistics on child obesity can be scary.

Close to 20 percent of America’s children deal with obesity, with some groups of children more affected than others.

While child obesity is a problem, it’s not an insurmountable one. A proper diet coupled with vigorous outdoor play can go a long way to keeping kids healthy.

The country has managed to begin reversing the obesity trend in children in recent years, as President Barack Obama said in his proclamation naming September National Child Obesity Awareness Month.
