I think this is pretty evident, observing your emotions when someone, a sibling loads up too much in a shared meal. If you ever tried fasting, you realize how much time we spend daily on food intake.

But let's not trivialize the issue. Most certainly, no-one here can even begin to understand starvation from experience. For starters, you would be in a total different state of mind, potentially delusional, disassociated, depressed, abulic, manic, have an altered perception of reality. During the Minnesota Starvation Experiment, participants mutilated themselves, one guy cut off three of his fingers with an axe and didn't remember why... in the rehab phase! Starvation is an holistic horror.
