I'm sorry I don't have the answer to this. But I noticed you had yet to receive a reply. So I thought I would write one. Hopefully other members will yet have more incisive insights to offer.

I suppose what you are experiencing could be a symptom of depression. I would also suppose it could suggest some sort of eating disorder; or perhaps it might be something that could lead to an eating disorder?

In my case, I used to like to eat (as well as cook.) But at this point in my life I just really don't much care. I eat because I have to. But I don't really care what it is as long as it's easy. I don't like sloppy food. Back when I used to go to restaurants, I tried to avoid anything on the menu that sounded as though it would be messy, such as some of the sandwiches restaurants serve up that have everything but the kitchen sink in them.
