Fasting is also an evidence of being elevated above the level of the body.
In it, we do not give the body all that it asks or desires of food. By so doing, we are elevated above bodily desires. We are even being elevated above materialism in general. And so we give the spirit a chance to take it's opportunity, remembering the Lord's saying: "Do not labour for the food which perishes, but for the food which endures to everlasting life" (Jn 6:27). And the Apostle's saying: "For to be carnally minded is death, but to be spiritually minded is life and peace." (Rom 8:6).
