I have food issues with my cat also. She has been the same weight for as long as I've had her. She hates dry food but I always have it available. She won't eat the cat food that's good for her only Fancy Feast. She snubs the food if it's been in the dish longer than 1/2 hour and she drives my son and I insane with her meowing when she is upset that we didn't give her what she wants. She's just too cute to be angry at for very long.
