Biblical Fasting requires abstaining from food. Nowadays, some will fast from things such as social media or tv and while that is good, especially if you recognize these as idols in your life, I suggest fasting from food in conjunction.
Similar to tithing (Matthew 6:1-4), fasting should be done in secret, in Matthew 6:18 (NIV) says “so that it will not be obvious to others that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you.”
Usually, if I’m fasting, I tell my family ahead of time in case I’m cranky or feel weak and tired.
Fasting takes me to another spiritual level in my walk with Jesus than anything else. Fasting will also provide revelation to questions I’ve been asking the Lord for. Fasting is a sign of obedience. It allows us to remove something i.e. food from our physical flesh to become more in tune with our spiritual well being. In fact, science has proven many health benefits to normal fasting, such as healing from diabetes, hypertension, arthritis, depression, schizophrenia, etc (see Science of Fasting). God is always moving, however, there is a sense of more increase or shift in certain areas of my life when I fast. If you’re wondering what type of fast you should start, pray and seek the Holy Spirit to provide you the answer.
4 ways to fast from food:
Here are some good guidelines for you to follow or modify as God directs.
1. The normal fast is going without food for a definite period during which you ingest only liquids (water and/or juice). The duration can be 1 day, 3 days, 1 week, 1 month or 40 days. Extreme care should be taken with longer fasts, which should only be attempted after medical advice from your physician. I definitely don’t recommend doing this if you’re pregnant. =)
2. The absolute fast allows no food or water at all, and should be short. Moses fasted for 40 days; but this would kill anyone without supernatural intervention, and should never be attempted today. Be sure to test the spirit that tries to talk you into a 40-day fast, even if it includes liquids.
3. The partial fast is one that omits certain foods or is on a schedule that includes limited eating. It may consist of omitting one meal a day. Eating only fresh vegetables for several days is also a good partial fast. John Wesley ate only bread (whole grain) and water for many days. Elijah practiced partial fasts at least twice. John the Baptist and Daniel with his three friends are other examples of those who participated in partial fasts. People who have hypoglycemia or other diseases might consider this kind of fast.
4. A rotational fast consists of eating or omitting certain families of foods for designated periods. For example, grains may be eaten only every fourth day. The various food families are rotated so that some food is available each day.
9 types of Spiritual Fasts
1. The Disciple’s Fast
Purpose: “To loose the bands of wickedness” (Isa. 58:6)—freeing ourselves and others from addictions to sin.
Key Verse: “This kind goeth not out but by prayer and fasting” (Matt. 17:21, KJV).
Background: Jesus cast out a demon from a boy whom the disciples had failed to help. Apparently they had not taken seriously enough the way Satan had his claws set in the youth. The implication is that Jesus’ disciples could have performed this exorcism had they been willing to undergo the discipline of fasting. Modern disciples also often make light of “besetting sins” that could be cast out if we were serious enough to take part in such a self-denying practice as fasting—hence the term “Disciple’s Fast.”
2. The Ezra Fast
Purpose: To “undo the heavy burdens” (Isa. 58:6)—to solve problems, inviting the Holy Spirit’s aid in lifting loads and overcoming barriers that keep ourselves and our loved ones from walking joyfully with the Lord.
Key Verse: “So we fasted and entreated our God for this, and He answered our prayer” (Ezra 8:23).
Background: Ezra the priest was charged with restoring the Law of Moses among the Jews as they rebuilt the city of Jerusalem by permission of Artaxerxes, king of Persia, where God’s people had been held captive. Despite this permission, Israel’s enemies opposed them. Burdened with embarrassment about having to ask the Persian king for an army to protect them, Ezra fasted and prayed for an answer.
3. The Samuel Fast
Purpose: “To let the oppressed (physically and spiritually) go free” (Isa. 58:6)—for revival and soul winning, to identify with people everywhere enslaved literally or by sin and to pray to be used of God to bring people out of the kingdom of darkness and into God’s marvelous light.
Key Verse: “So they gathered together at Mizpah, drew water, and poured it out before the Lord. And they fasted that day, and said there, ‘We have sinned against the Lord’ ” (1 Sam. 7:6).
Background: Samuel led God’s people in a fast to celebrate the return of the Ark of the Covenant from its captivity by the Philistines, and to pray that Israel might be delivered from the sin that allowed the Ark to be captured in the first place.
4. The Elijah Fast
Purpose: “To break every yoke” (Isa. 58:6)—conquering the mental and emotional problems that would control our lives, and returning the control to the Lord.
Key Verse: “He himself went a day’s journey into the wilderness.… He arose and ate and drank; and he went in the strength of that food forty days and forty nights” (1 Kings 19:4, 8).
Although Scripture does not call this a formal “fast,” Elijah deliberately went without food when he fled from Queen Jezebel’s threat to kill him. After this self-imposed deprivation, God sent an angel to minister to Elijah in the wilderness.
5. The Widow’s Fast
Purpose: “To share [our] bread with the hungry” and to care for the poor (Isa. 58:7)—to meet the humanitarian needs of others.
Key Verse: “The jar of flour was not used up and the jug of oil did not run dry, in keeping with the word of the Lord spoken by Elijah” (1 Kings 17:16, NIV).
Background: God sent the prophet Elijah to a poor, starving widow—ironically, so the widow could provide food for Elijah. Just as Elijah’s presence resulted in food for the widow of Zarephath, so presenting ourselves before God in prayer and fasting can relieve hunger today.
6. The Saint Paul Fast
Purpose: To allow God’s “light [to] break forth like the morning” (Isa. 58:8), bringing clearer perspective and insight as we make crucial decisions.
Key Verse: “And he [Saul, or Paul] was three days without sight, and neither ate nor drank” (Acts 9:9).
Background: Saul of Tarsus, who became known as Paul after his conversion to Christ, was struck blind by the Lord in the act of persecuting Christians. He not only was without literal sight, but he also had no clue about what direction his life was to take. After going without food and praying for three days, Paul was visited by the Christian Ananias, and both his eyesight and his vision of the future were restored.
7. The Daniel Fast
Purpose: So “thine health shall spring forth” (Isa. 58:8, KJV)—to gain a healthier life or for healing.
Key Verse: “Daniel purposed in his heart that he would not defile himself with the portion of the king’s delicacies, nor with the wine which he drank” (Dan. 1:8).
Background: Daniel and his three fellow Hebrew captives demonstrated in Babylonian captivity that keeping themselves from pagan foods God had guided them not to eat made them more healthful than others in the king’s court.
8. The John the Baptist Fast
Purpose: That “your righteousness shall go before you” (Isa. 58:8)—that our testimonies and influence for Jesus will be enhanced before others.
Key Verse: “He shall be great in the sight of the Lord, and shall drink neither wine nor strong drink” (Luke 1:15, KJV).
Background: Because John the Baptist was the forerunner of Jesus, he took the “Nazirite” vow that required him to “fast” from or avoid wine and strong drink. This was part of John’s purposefully adopted lifestyle that designated him as one set apart for a special mission.
9. The Esther Fast
Purpose: That “the glory of the Lord” will protect us from the evil one (see Isa. 58:8).
Key Verses: “Fast for me … [and] my maids and I will fast … [and] I will go to the king … [and] she found favor in his sight” (Esther 4:16; 5:2).
Background: Queen Esther, a Jewess in a pagan court, risked her life to save her people from threatened destruction by Ahasuerus (Xerxes), king of Persia. Prior to appearing before the king to petition him to save the Jews, Esther, her attendants and her cousin Mordecai all fasted to appeal to God for His protection.
