A Big Mac has 540 calories. A kid's meal with Chicken McNuggets, small fries, and chocolate milk has almost 600 calories. That's nearly half the recommended calories in a whole day's meals for a child.

Daniel Conway is with the California Restaurant Association. He says nutritional information can help people make healthier decisions. But, he says it's only part of the solution in fighting obesity.
"Providing information doesn't necessarily dictate people's behavior. I've heard from some people that if it's their birthday or their anniversary or something they don't care how many calories are on whatever they're eating."
