I think that is a general disinterest in food...
I don't eat out very often at all.
I don't go out very much at all, either.

It's like, I can go into a supermarket and see nothing to eat, whereas most people can see loads of food.
I get jealous of people who get very excited about food - I can't.
I used to have a friend who would describe a meal with such enthusiasm as to be almost inspiring - I wish I had that. To me, I can't wait til they invent a pill that would constitute a meal....put a pill on a plate, drop some water on it, and 'hey presto!', roast beef dinner....

Oooh..I got major de ja vu then!
