Fasting is hungering for God. When you fast food, you help create a deeper hunger for God activating your spiritual hunger hormone. It may not feel enjoyable physically when we fast, but you are fulfilling your spiritual hunger.
WORD KNOWLEDGE WORD WISDOM
For to one is given through the Spirit the utterance of wisdom, and to another the utterance of knowledge according to the same Spirit,(ESV)

For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.
