St. Benedict's rule prescribed a great many fasts, over and above the ecclesiastical fast of Lent; but it made this great distinction between the two: that whilst Lent obliged the monks, as well as the rest of the faithful, to abstain from food till sunset, these monastic fasts allowed the repast to be taken at the hour of None.

If you're worried you’ll be starving while fasting, you’ll be pleasantly surprised! Intermittent fasting decreases your hunger hormone ghrelin, which in turn can increase dopamine levels in the brain. (Just another example of the gut-brain axis at work.) Fasting can also help free people from emotional eating and kill cravings by transitioning your metabolism from unstable sugar-burning to steady fat-burning.

Intermittent fasting also has a number of added benefits over strict calorie restriction. For starters, it's a lot easier to comply with, and compliance is everything. The calorie restriction route is also extremely dependent on high quality nutrition — you want to sacrifice calories without sacrificing any important micronutrients — and this can be another hurdle for many who are unfamiliar with nutrition and what actually constitutes a healthy diet.
Christian fasting isn't some kind of a "work" that's commanded by Christ or required by Scripture. However, that doesn't mean that fasting isn't recommended as a part of our spiritual growth. The Book of Acts records believers fasting before they made important decisions (Acts 13:4; 14:23). Fasting and prayer are often linked together (Luke 2:37; 5:33). Too often, the focus of fasting is on the lack of food. However, the purpose of fasting is to take our eyes off the things of this world and instead focus on God. Fasting is a way to demonstrate to God and to ourselves that we are serious about our relationship with Him. Although fasting in Scripture is almost always a fasting from food, there are other ways to fast. Anything you can temporarily give up in order to better focus on God can be considered a fast (1 Corinthians 7:1-5). Fasting should be limited to a set time, especially when the fasting is from food. Extended periods of time without eating are harmful to the body. Fasting is not intended to punish our flesh, but to focus on God.

When it comes to intermittent fasting, there’s no one-size-fits-all. Bulletproof Intermittent Fasting fits all your eating into a 6-hour window, leaving you with an 18-hour-fast each day. This is often called “18:6” fasting. You can also try variations such as the one-meal-a-day method, or fasting every other day. The key is to experiment and listen to your body to see what works best for you. If intermittent fasting causes fatigue or other negative symptoms, try fasting just once or twice a week, and build up from there.
Fasting in the Ethiopian Church implies abstention from food and drink. No animal products are consumed, including dairy, eggs and meat, and utensils that have touched such products must be washed before touching the strictly vegan foods that are consumed on fast days. During fast periods, Holy Liturgy (Mass) is held at noon (except on Saturdays and Sundays), and because no food can be consumed before communion, it is traditional for people to abstain from food until mass is over (around 2 to 3 in the afternoon). Every Wednesday and Friday are days of fasting because Wednesday is the day that the Lord was condemned and Friday is the day he was crucified (the Wednesdays and Fridays between Easter Sunday and Pentecost Sunday are an exception as well as when Christmas or Epiphany fall on a Wednesday or a Friday). The fasts that are ordained in the canon of the Church of Ethiopia are:

BUT I stopped losing weight since last 2 weeks, so I stopped doing IF for last a week and my tummy looks same as before and I gained 3/4 lbs back. I am trying to do IF again but I cannot, because I’m getting constantly hungry. I used to start Fasting at 7pm & & break at 11/12pm next day. But My new job schedule is from 5:30, so its hard for me to wait until noon. I tried a different schedule from 4pm to 8am but I get hungry at night, so it didn’t help me either. Please help me.
Fasting can take some time to get used to, as your body sheds old habits and learns new ones. But listen to your body! If you’re in hour 10 of 16 hours of fasting and feel like you absolutely need a snack, then have one. If your fasting time is up but you’re not hungry yet, wait until you are. There are no hard and fast rules here. You’re not “messing up.” You might find it helpful to jot down a sentence or two each day about how you felt; you might find that certain times of the  month or year, different types of fasts work better for you.
The second major day of fasting is Tisha B'Av, the day approximately 2500 years ago on which the Babylonians destroyed the first Holy Temple in Jerusalem, as well as on which the Romans destroyed the second Holy Temple in Jerusalem about 2000 years ago, and later after the Bar Kokhba revolt when the Jews were banished from Jerusalem, the day of Tisha B'Av was the one allowed exception. Tisha B'Av ends a three-week mourning period beginning with the fast of the 17th of Tammuz. This is also the day when observant Jews remember the many tragedies which have befallen the Jewish people, including the Holocaust.
Let me assure you at the outset of this book that I am not advocating prolonged periods of fasting for every believer. A fast can be as short as one meal. Neither do I advocate fasting and praying for the mere sake of saying with self-righteousness, "I have fasted and prayed about this." I do not advocate fasting so that the hungry in a foreign nation might have the food you would have eaten that day -- which is highly unlikely. I do not advocate fasting apart from prayer.
Another perk? There are no “forbidden foods,” and no counting calories, weighing food or restricting your diet, which makes it a bit easier to follow. That said, this isn’t a free-for-all. “You still have to eat like a grown-up,” Pilon says. It’s all about moderation: You can still eat whatever you want, but maybe not as much of it. (A slice of birthday cake is OK, he says, but the whole cake isn’t.)
When you don’t eat any food for a set period of time each day, you do your body and your brain a whole lot of good. It makes sense from an evolutionary standpoint. For most of history, people weren’t eating three square meals a day, plus grazing on snacks. Instead, humans evolved in situations where there wasn’t much food, and they learned to thrive when fasting.[1] Nowadays, we don’t have to hunt for food (although hunting for your own meat isn’t a bad idea!). Rather, we spend most of our days in front of computers, and we eat whenever we want — even though our bodies aren’t adapted to this behavior.

By the ninth century b.c. fasting had become institutionalized or formalized to the extent that days or other periods of fasting were called as occasions for public worship. The usual way of describing such convocation is "to call for" or "proclaim" a fast. Thus, Jezebel, to provide an occasion whereby Naboth would be unjustly accused and condemned, proclaimed a fast ( 1 Kings 21:9 1 Kings 21:12 ). Jehoshaphat later, and with much nobler motives, called for such an assembly in order to implore God's intercession on Judah's behalf ( 2 Chron 20:3 ). The same formula appears in ezr 8:21 and jon 3:5, in the last instance initiated by the people of Nineveh as an expression of their repentance at Jonah's preaching.

Although the findings with mice are well established there’s less evidence that time restricted eating works for humans. One human study found significant weight loss when participants fasted for 11 hours overnight compared with control conditions. Another study found a 4.1 percent weight loss resulting from consuming a single meal in the afternoon although self-reported hunger was greater the next morning. Other studies haven’t supported night-time fasting for humans so it’s too early to draw definitive conclusions but you might want to experiment to see if it would work for you.

Feelings over hunger may also become more tolerable over time. Studies of alternate-day fasting have shown that people rate their hunger at 8 on a scale of 1 to 10 for their first few fast days, but after two weeks, that number drops to 3. Mattson puts the window at three to four weeks, after which, he says, "you're not hungry on fasting days." (Try clean eating to shed stubborn pounds. This plan gives you 150 delicious recipes you'll love!)
On the other five days of the week, there's no calorie cap, and no food is off-limits. This freedom isn't permission to binge and make up for your two fast days, but it does mean you shouldn't feel guilty about eating a slice of cake. U.S. News experts evaluate the Fast Diet poorly in all rankings, mostly due to its tough-to-follow nature and health risks in some populations.
The Armenian Apostolic Church (with the exception of the Armenian Patriarchate of Jerusalem) has followed the Gregorian Calendar since 1923, making it and the Finnish Orthodox church the only Orthodox churches to primarily celebrate Easter on the same date as Western Christianity. As a result, the Armenian church's observation of Lent generally begins and ends before that of other Orthodox churches.
We begin this holy season by acknowledging our need for repentance and our need for the love and forgiveness shown to us in Jesus Christ. I invite you, therefore, in the name of Christ, to observe a Holy Lent, by self-examination and penitence, by prayer and fasting, by practicing works of love, and by reading and reflecting on God's Holy Word.[72]

View fasting as a response instead of a request. Don’t use fasting as a way to try to get the results you want from your prayers. Adding fasting to your requests to God when you want to convince Him to answer your prayers in a certain way amounts to using fasting as a manipulative tool. Instead of fasting to try to get God to respond to you, fast to respond to God. When you notice God at work in a special way in your life, you can express your awe, gratitude, and love back to Him by fasting. In the process, you may experience God’s presence on a deeper level. But fasting doesn’t guarantee any particular results. Fasting is simply a natural, inevitable response of a person to a grievous sacred moment in life – a moment when focusing on the physical pleasures of eating pales in comparison to focusing on the spiritual reality you’re encountering. Rather than fasting for what you can get from God, fast for what you can give to God. Fasting is simply a way of worshipping Him.
You’ll spike your blood sugar when you eat. If you’re fasting on a high-carb diet and you’ve powered through the cravings and lack of energy from low blood sugar, there’s a good chance you’ll eat a ton of carbs when you feast. You want to eat big meals when you fast to make sure you’re getting enough calories, but all those excess carbs in one go will spike your blood sugar in the opposite direction, from low to high.[14] High blood sugar causes fatigue and lack of focus. That raging hunger will also cause you to binge unnecessarily, and whatever carbs you don’t use will get stored as fat.
I take a 1200 calorie diet and I exercise. A lot. In the morning I have a cup of coffee and do a 1:30hr workout consisting of 2 HIIT workouts and a strength workout along with A 20 minute fat burning yoga. I open my fast at 2pm and stop eating at 8pm after 3 hours before sleeping I do another 1 hr workout. One HIIT workout and some cardio. Then I go to sleep. Acc to my calorie calculator I burn around 600-800 calories. I try my best to eat as healthy as possible but I’m seeing no results. I tried following all the advices I could find but I don’t understand what’s wrong. People are losing this much weight in a week. It’s very disheartening for me.
^ Smith, Larry D. (September 2008). "Progressive Sanctification" (PDF). God's Revivalist and Bible Advocate. 120 (6). Principles which underlie our Wesleyan/holiness heritage include such commitments as unquestioned scriptural authority; classical orthodox theology; identity with the one holy and apostolic church; warmhearted evangelical experience; love perfected in sanctifying grace; careful, disciplined living; structured spiritual formation, fidelity to the means of grace; and responsible witness both in public and in private—all of which converge in holiness of heart and life, which for us Methodists will always be the “central idea of Christianity.” These are bedrock essentials, and without them we shall have no heritage at all. Though we may neglect them, these principles never change. But our prudentials often do. Granted, some of these are so basic to our DNA that to give them up would be to alter the character of our movement. John Wesley, for example, believed that the prudentials of early Methodism were so necessary to guard its principles that to lose the first would be also to lose the second. His immediate followers should have listened to his caution, as should we. For throughout our history, foolish men have often imperiled our treasure by their brutal assault against the walls which our founders raised to contain them. Having said this, we must add that we have had many other prudentials less significant to our common life which have come and gone throughout our history. For instance, weekly class meetings, quarterly love feasts, and Friday fast days were once practiced universally among us, as was the appointment of circuit-riding ministers assisted by “exhorters” and “local preachers.”

Prepare yourself to encounter God through fasting. When you realize that your intimacy with God is superficial and you long to experience Him more directly, respond by fasting, and you may find that you encounter God more deeply and powerfully. Through fasting, render yourself freer to hear from God through prayer than you may be when you’re not fasting. Let your love for God motivate you to reach out to Him through fasting.
To conduct the study, researchers divided the 150 individuals into three groups: a control group that wasn’t asked to change their diets; a group that followed the 5:2 diet; and a group that followed a more conventional diet of continuously restricting their calorie intake by 20 percent. During the first few months of the experiment, a nutritionist monitored the participants to make sure they adhered to the diets; the next few months saw the participants monitor their own diets.
In some specific periods of time (like Caturmasya or Ekadashi fasting) it is said that one who fasts on these days and properly doing spiritual practice on these days like associating with devotees -sangha, chanting holy names of Hari (Vishnu, Narayana, Rama, Krishna) and similar (shravanam, kirtanam vishno) may be delivered from sins.[citation needed]

Fasting for Jews means completely abstaining from food and drink, including water. Traditionally observant Jews fast six days of the year. With the exception of Yom Kippur, fasting is never permitted on Shabbat, for the commandment of keeping Shabbat is biblically ordained and overrides the later rabbinically instituted fast days. (The optional minor fast of the Tenth of Tevet could also override the Shabbat, but the current calendar system prevents this from ever occurring.[89])


It’s important to understand that fasting, as part of The Fast Diet, does not mean starving yourself. In The Fast Diet, you limit the amount and the kind of food you put into your body on a daily basis. So, if you are looking to fast throughout the day, don’t skip lunch — just eat fewer calories. If you normally eat a sandwich and chips for lunch, swap that out for a salad and an apple — this meal is significantly fewer calories and healthier for you too!
On weekdays of the first week of Great Lent, fasting is particularly severe, and many observe it by abstaining from all food for some period of time. According to strict observance, on the first five days (Monday through Friday) there are only two meals eaten, one on Wednesday and the other on Friday, both after the Presanctified Liturgy. Those who are unable to follow the strict observance may eat on Tuesday and Thursday (but not, if possible, on Monday) in the evening after Vespers, when they may take bread and water, or perhaps tea or fruit juice, but not a cooked meal. The same strict abstention is observed during Holy Week, except that a vegan meal with wine and oil is allowed on Great Thursday.[47]
