The statistics are alarming. Two-thirds of U.S. adults are overweight and half of that group is considered obese.  It's not just adults who are tipping the scales; kids are gaining weight too.  One-third of all school age children are overweight. But thanks to a group of nurses, that may change.

These fourth graders are getting a fun lesson in healthy living. Their song and dance is part of a study designed to help kids develop healthy habits early.

“It really does take a village or a whole group of us in a community to come together to look at how can we shape healthier habits for life? And how can we help support parents on their journey of raising children?" Sharon Tucker, a nurse at Mayo Clinic said.

Tucker says the study gets kids and their families focused on four goals: the 5210 Plan.

"The five is five servings of fruits and vegetables a day. The two is no more than two hours of TV or computer a day," fourth-grader Joise Breeze said.

"One hour of exercise or more. And 0 stands for zero sugar drinks," fourth-grader Ben Anderson said.

The program includes tips on how to fit these goals, one at a time, into real life.

"I'm learning not to watch so much TV and eat more fruits and vegetables," Dana Brandt, a fourth-grader, said.

Because research shows that if children develop healthy habits while they're young, they're more likely to maintain those habits as adults.
