When you send your kids to school you expect them to feed their hunger for knowledge. But some parents have learned their kids are being forced to focus more on their hungry tummies.
That is sparking a new backlash against first lady Michelle Obama's healthy food program for schools.
Critics argue the new school meals don't include enough calories for growing kids. Ironically, it's part of the "Healthy, Hunger-Free Kids Act" which President Obama signed into law in 2010.
The new nutritional guidelines require limiting the amount of calories in school lunches.
The administration's goal is to end childhood obesity. Instead it has sparked a revolt by hungry students.
One group of Kansas students created a video mocking the guidelines. It shows kids collapsing on the volleyball court, stashing junk food in their lockers and day-dreaming about heartier meals.
One high school english teacher told US News & World Report, "I have been a teacher for 20 years, and this is the worst that it's ever been. Our kids eat at 12:06, and they are hungry by 1:30."
