Heavy(1995)

He's a man so shy, he doesn't even think he deserves love…

Victor is a cook who works in a greasy roadside restaurant owned by his mother, Dolly. It's just the two of them, a waitress named Delores, and a heavy drinking regular, Leo. But things change when Callie, a beautiful college dropout, shows up as a new waitress and steals Victor's heart. But Victor is too shy to do anything about it, and too self-consciously overweight to dream of winning Callie away.
