"Fat Farm" is a short story by American writer Orson Scott Card.
Originally published in the January 1980 issue of Omni magazine, it also appears in his short story collection Maps in a Mirror.
After Barth has legally transferred his identity to his replacement and it is too late to change his mind, he is told that he is now the property of the company that runs the clinic.
The short story "Fat Farm" was made into a comic which appears in the October 2005 issue of InterGalactic Medicine Show.
The art for this comic was done by Jin Han and the script was written by Aaron Johnston, who also co-authored the novel Invasive Procedures with Card.
