201 3rd-6th graders were randomly assigned to receive one of four different snacks: 1. Potato chips. 2. Cheese. 3. Vegetables. 4. Cheese and vegetables. Simulating many homes, the kids were allowed to eat as much of their assigned snack while watching a 45 minute television program. Perceived fullness was measured before, midway through and after the 45 minutes.
