At Carrie Martin Elementary students are getting a special lesson in how their body works. 

"I leaned that if you eat healthy your brain will get stronger," said 4th grade student Jaionna Hogan. 

Hogan took part in a program called "Body Walk" presented by LSU AG Center. 

"It's an exhibit for kids to try to learn more about their body and that they need to exercise. There are 11 stations inside the body and we start them out in the brain," says John Albrado. 

Albrado says the goal is program is to teach students how certain foods affect their body in hopes of curbing childhood obesity in the state. 

" It has been proven that obese kids tend to have lower test scores," says Albrado. 

Currently 47.54% of students in Louisiana between the ages of 5 and 17 are fat. And the state ranks 4th in the nation for childhood obesity. 

The CDC recommends and hour of intense activity several days a week if not daily to prevent obesity. It's also recommended that parents moderate portion sizes and to limit drinks filled with sugar, opting for to drink more water instead.
