All his life, Dominic DiNapoli (Dom DeLuise) has found comfort in food. But when his sister Antoinette (Anne Bancroft, who also wrote and directed) implores him to stop eating himself into an early grave, Dominic begins bouncing from crash diets to the support group "Chubby Checkers" to all manner of binges in between. Throughout this painful process, Dominic discovers that what he needs most is a steady diet of love - from his family, from a new and lovely neighborhood acquaintance... and most importantly, from himself.
