I've had conversations on similar aspects to this many times. There are many psychological issues involved but the highlights are: 1. People eat for many reasons, sustenance being only one.

"The sooner you can adjust your mental view to treating food as nothing more than fuel, the better off you'll be" Better off how? Eating for enjoyment is one of the best pleasures in life.

I really can't emphasize how bad a feeling that is. I love butter, but I'd trade it in a heart beat to never feel that again. Who knows, maybe it's the same whether it's in your control or not.
