Often assumed to mean someone is full, touching the stomach after eating actually signifies satisfaction. "They want to hold in the pleasant feeling," says Wood.
Whereas people who like their food will surround their plate, those who don't will often lean away, pulling back their chests or leaning against the back of the chair.
