To put it into an extreme: for someone who's schizoid even your own physical body can be experienced as something foreign/detached from your psyche. I seldom enjoy a meal. I just eat it because if I don't I will feel out of energy later or already do. You can only ignore a feeling of hunger so long. Thinking of what to eat is a struggle because there is nothing that would come to my mind because I love it. I usually end up eating something I already know, is convenient etc.
