Fatso  (1980)

Theatrical Release Information:
Fatso

In this dark and sometimes sad comedy, Dominick -- an extremely obese man -- is pushed by his sister Antoinette to shed a few pounds lest he end up dead like his cousin. To do so, she helps him enroll in the fanatical weight-loss group, the Chubby Checkers, who will do anything to keep fellow members from over-eating. Another incentive for Dominick is his love for Lydia, a women whom Dominick fears has deserted him because of his obesity.The process of weight loss is torture, and he is left with a painful choice (one that the naturally thin don't always understand), suffer the pain and lose the weight or somehow learn to live with it. After his initial attempts to lose weight end in failure, and he goes on a gigantic food bender (one of the great binge scenes in movie history), in the end, Dominick learns that Lydia loves him for who he is, and he decides that he should do himself the same favor. ~ Sandra Brennan, All Movie Guide
