Durch dick und dünn (1987)

Eva, a successful publicity executive, has weight problems. In spite of diets and starvation cures she is overcome frequently by attacks of compulsive eating so that all resolutions and efforts to reduce weight are of no avail. She becomes more and more frustrated. Her new boyfriend Thomas does his best to pep her up but it doesn't help her self esteem.
Finally, after she ditches her date with Thomas because she can't find the right dress to wear, she flies into a rage and -in an act of self-liberation- throws her clothes and scale through a closed window.
