Speaking personally, it's very easy to me to be able to completely separate the thought of food from having to be enjoyable. I don't drink water because it tastes good, I drink water because I know I need to drink water. I don't eat a plain sandwich at lunch because it tastes good, I eat that sandwich at lunch because I am hungry and know I need to eat. I don't need my food to taste good for me to eat it. If that has to do with habits or genes, I have no idea.

And that doesn't mean I don't get enjoyment from eating. I certainly enjoy an occasional nice steak or a few slices of cake every now and then, but I don't eat meat every meal despite it tasting enjoyable, just like I imagine you don't eat cake every meal despite it tasting wonderful,
