Is your fast drawing you closer to Jesus, or is it just easy for you to do? The challenge is for it to be hard, so you can rely on God to sustain you. We do it to please the Lord. If you're not expecting from the Lord, you are just on a fancy diet...and no one wants that :)
We encourage to use the times of temptations to lean in to God and His presence within you...it's a good reminder to rely on God when your body is fighting against you, and to pray for what you're fasting for.
