My go-to answer has been that Tracen makes a change in food vendors for the cafeteria, and whoops it's all really fattening and addicting! POV would be tricky, would probably be some unnamed jobber Uma.
But past that, I think more about the "ok everyone's fat, what now?" stage, which is like where the good stuff is anyway. The dorms in particular gotta worry about the girls on the upper floors taking "quick" ways down (or getting stuck trying to).
