Stuffing

I lose my appetite and feel like i can’t eat anymore, but i’m far from stuffed

Whenever I want to stuff myself, I tend to lose my appetite to where the food taste bland and horrible and I don’t enjoy it anymore. I haven’t been able to get stuffed beyond capacity before. I follow SnackedoutJackie and I WISH to have a body like here, her belly looks like the only fat part, and it always looks super big and tight.
Any idea how I can push past my appetite and eat however much I want?
