Ask God what He wants you to pray about while fasting. Is it praying about a very important decision you need to make, or is it releasing to God an unsaved child/ spouse, a worried heart, a divorce, an illness, a painful situation, a new job, a move, a financial burden, an addiction, etc.? Whatever your specific situation is, God’s purpose for you to fast and pray is for you to focus on Him, laying your burdens down at His feet.
During your fast, you will spend more time with God than you did previously. Expect changes to take place in your heart and life as you get closer to God.
Fasting is as important as any of the other spiritual habits that believers should incorporate into their lives. It will help you have a closer relationship with God. It also helps with self-control by denying yourself something you desire, such as food.
Before you start fasting, pray and ask for God's direction and guidance to see if He is leading you to begin a fast.
If you have health problems, or are unsure, call your doctor for medical advice.
If you are pregnant or nursing a baby, do not fast.
Write down specific prayer requests and thanksgivings related to your fast. (But remember: Fasting is not done as an attempt to get something from God, only to submit to His Will.)
Expect to be blessed by God as you fast, pray, and honor Him.
Decrease the frequency of your meals and the portions of your food two days prior to fasting. Don't aim at "storing up" by overeating before a fast.
The day before you start your fast, eat raw vegetables and fresh fruits.
If fasting on your own, don't boast about it! It is between God and you.
Set aside time to pray and enjoy God's presence. He is the sole focus of your fast. Read the Word of God and keep a journal to write your conversations with Him.
While on a fast, drink lots of water.
While fasting, continue your regular activities, but this is not a good time to start any new strenuous exercise.
Agree with God when He brings attention to sins in your life. ("Confess" means to agree with God.)
If you are completing an extended fast, break your fast gently by eating some fruits. Remember, do not overeat after a fast!
