Causing severe pain or anguish. Withholding a day's rations would be considered torture if the prisoner has reason to believe his or her captors would go so far as starvation methods.

It is not that physiologically damaging, but it is a psychological assault. It is degrading and it raises the question of basic human rights. Though it might seem mild, withholding a day or more worth of rations would be a form of torture as this is the starvation threshold. Even if we would be reluctant to call it outright torture, it isn't a practice one should do if they wish to avoid violating human rights.
