Auto Cannibalism

"left hand washes the right don't let your left hand know what your right hands doing one potato two potato three potato four we got a refrigerator with a store-more door hahaha. Who cares, this hand or that. good food good meat good God let's eat. lady fingers they taste just like lady fingers"

- Stephen King, "Survivor Type"

How do you take the already disturbing concept of cannibalism and make it even more screwed up? Why, by making the diner what's also being served, of course!

The reason for why the Hell someone makes a meal of themselves tends to fall under one of the following three categories - an extreme last resort due to imminent starvation, a form of Cold-Blooded Torture inflicted upon someone by a particularly sadistic captor, and simple insanity.

A character eating a clone or duplicate of themselves also counts. Also see I Taste Delicious, which tends to be about characters finding themselves irresistibly delectable after becoming or being covered in food (try to keep examples of that on its page). Some of the more disturbing examples of Let's Meet the Meat (like the image of that page) can involve this.

Your body will also actually do this automatically in the later stages of starvation; breaking down redundant organs and muscle to keep the more vital parts running.
