A Texas school has a new way to battle childhood obesity -- a candid camera.
Children at a San Antonio elementary school are a part of a $2 million, U.S. government funded program to see if anti-obese campaigns work.
A camera snaps a picture of students trays before they start eating and then again when they throw away their leftovers.
The calories consumed are counted and recorded.
"We're going to see if its healthy or not healthy," said one third grader.
"They try to get you healthy and have good shape in your body and stuff," said a fourth grader.
"This feedback is going to be provided to parents so they can help us raise healthier children," explained Dr. Roberto Trevino, M.D., the director of the Social and Health Research Center.
Critics say the calorie cameras go too far. However, those behind the cameras say they're just looking to make parents more aware of what their children are eating.
