This is an unattractive subject. Yet, fasting is a spiritual discipline that should be regularly practiced by most Christians.
One powerful benefit as explained in Isaiah 58 is that it breaks chains and yokes of spiritual strongholds. These are influences of evil that have control over people who are themselves powerless to break free from. When we experience these in-explainable irritations, maybe its time to deny ourselves some food and spend that time in prayer about the challenge.
Jesus Himself said, “This kind of demon won’t leave unless you have prayed and gone without food.” [Matt. 17:21]
