There's the movie 'Feed'.
Not movies but...
In king of Queens Carrie isn't so happy when Doug loses weight, because she apparently doesn't look as good in comparison, so she tries to fatten him up again.
There was an episode of Malcolm in the Middle with Hal secretly fattening up Lois, because he likes the bigger her.
Same in Family Guy, but not secretly, just rather forcefully.
In the Animaniacs parody of Star Trek there's some extreme feeding.
