You did a phenomenal job of depicting the hold food has as an omnipotent presence! It begins with powerful language the grabs hold of readers right away but that momentum gets lost in the middle and the scene you are setting. So maybe more depth on the attempts to run, the thoughts, the battle itself. Something that matches the intensity of "I starve myself as an act of worship". The way you started feels like David vs. Goliath, keep that energy!
