Watch Fingers on the Belly (1988)

Fingers on the Belly

A young woman wanders through Paris spending most of her time eating all the junk she can: in a fast-food, out of a tin can and so on. She steals some more food in a supermarket, meets a friend who gently carresses her belly in the street, then goes back home where she makes herself vomit in the toilets. She is then ready for the family dinner.
