Third, you've probably already fasted many times, even though you don't know it. Have you ever slept in late on the weekends and then had a late brunch? Some people do this every weekend. In situations like these, we often eat dinner the night before and then don't eat until 11am or noon or even later. There's your 16–hour fast and you didn't even think about it.

In many Lutheran churches, the Sundays during the Lenten season are called by the first word of their respective Latin Introitus (with the exception of Palm/Passion Sunday): Invocavit, Reminiscere, Oculi, Laetare, and Judica. Many Lutheran church orders of the 16th century retained the observation of the Lenten fast, and Lutherans have observed this season with a serene, earnest attitude. Special days of eucharistic communion were set aside on Maundy Thursday and Good Friday.

The sense of "living an unrestrained life" (usually of women) is from 1746 (fast living is from 1745). Fast buck recorded from 1947; fast food is first attested 1951. Fast-forward first recorded 1948. Fast lane is by 1966; the fast track originally was in horse-racing (1934); figurative sense by 1960s. To fast talk someone (v.) is recorded by 1946.
Whether a regimen calls for two fasting days a week or eating your meals in a smaller "window" of time in the day, all plans share a near-freedom from calorie counting, a big plus for weary food diarists. Once you have planned your fasting-period menu—say, a 500-calorie day of chicken and veggies—you're set. And in your nonfasting periods, you eat normal, healthy meals (even that steak!) without worrying about every bite.

The Bible has only one command regarding fasting: God’s people are commanded to fast on the Day of Atonement from sundown to sundown (Leviticus 23:27-32 Leviticus 23:27-32 27 Also on the tenth day of this seventh month there shall be a day of atonement: it shall be an holy convocation to you; and you shall afflict your souls, and offer an offering made by fire to the LORD. 28 And you shall do no work in that same day: for it is a day of atonement, to make an atonement for you before the LORD your God. 29 For whatever soul it be that shall not be afflicted in that same day, he shall be cut off from among his people. 30 And whatever soul it be that does any work in that same day, the same soul will I destroy from among his people. 31 You shall do no manner of work: it shall be a statute for ever throughout your generations in all your dwellings. 32 It shall be to you a sabbath of rest, and you shall afflict your souls: in the ninth day of the month at even, from even to even, shall you celebrate your sabbath.


We are not to fast to have people feel sorry for us or to think we’re pious (Matthew 6:16-18 Matthew 6:16-18 16 Moreover when you fast, be not, as the hypocrites, of a sad countenance: for they disfigure their faces, that they may appear to men to fast. Truly I say to you, They have their reward. 17 But you, when you fast, anoint your head, and wash your face; 18 That you appear not to men to fast, but to your Father which is in secret: and your Father, which sees in secret, shall reward you openly. 

Cons: Even though there is flexibility in when you eat, Leangains has pretty specific guidelines for what to eat, especially in relation to when you’re working out. The strict nutrition plan and scheduling meals perfectly around workouts can make the program a bit tougher to adhere to. (You can learn more about the specifics — as well as when to time these meals — directly from Leangains here and here.)

Intermittent fasting (specifically the 5:2 diet) became popular in the UK in 2012[10][11][12] after the BBC2 television Horizon documentary Eat, Fast and Live Longer.[13] Via sales of best-selling books, it became widely practiced.[14][15] In the United States, intermittent fasting has become a trend among Silicon Valley companies.[16] According to NHS Choices as of 2012, people considering the 5:2 diet should first consult a physician, as fasting can sometimes be unsafe.[14][17] A news item in the Canadian Medical Association Journal expressed concern that promotional material for the diet showed people eating high-calorie food, such as hamburgers and chips, and that this could encourage binge eating since the implication was that "if you fast two days a week, you can devour as much junk as your gullet can swallow during the remaining five days".[18]

When your empty stomach starts to growl and begins sending your brain every “feed me” signal it can, don’t be content to let your mind dwell on the fact that you haven’t eaten. If you make it through with an iron will that says no to your stomach, but doesn’t turn your mind’s eye elsewhere, it says more about your love for food than your love for God.

Another aspect of fasting for God is comparable to a person dedicating an action to a cause. For God and country was, at one time, a familiar declaration in the United States.  It implied that the action being taken was to answer a noble call and serve a higher motive, the expectation of reward or compensation being far removed. The motivation came from a spiritual, emotional and dedicated commitment to do what is right. Similarly, a fast may be undertaken for God because it represents a lofty act, a selfless commitment to an act considered meritorious and virtuous.
Several animal studies demonstrated that intermittent fasting based on daily circadian rhythms prevents weight gain. Mice given unlimited access to high-fat lab chow ate throughout the day and night which resulted in obesity and type 2 diabetes. Other mice fasted for 16 hours and actually consumed the same amount yet they didn’t gain weight or have negative health consequences. The findings suggest that it was the timing of eating, rather than the amount consumed which determined weight gain.

There may also be other intermittent fasting benefits: A 2017 study from the University of Southern California followed 71 adults who were placed on a low-calorie, fasting-mimicking diet for five days each month for three months. After following the diet, researchers found that the diet reduced cardiovascular risks, including blood pressure, inflammation, and body fat, in participants. A 2018 study from the British Journal of Nutrition backs this up after overweight participants followed the 5:2 method and saw improvements in their triglyceride levels and blood pressure. Other studies have also shown that IF may help with relieving MS symptoms, but more studies are needed on a larger scale and for a longer period of time to support these claims.

Fasting is not the first dietary approach to excite researchers. Before fasting, there was caloric restriction, or CR. The methods have much in common. Overall, they both drastically reduce energy intake and bring about similar health benefits. They’re like siblings in a way, especially since fasting studies emerged from work on CR. And now, many former CR researchers are exploring fasting, often setting the two against each other in the lab.
I recommend counting calories—not forever, but for about two weeks—so you get a feel for what a regular day of eating feels like. I have used and like Cron-o-meter, Lose It!, and Fitbit to track calories. Don’t get bogged down in the details. If a type of food you ate is not in the database, find something similar or make an educated guess. You just want to make sure you’re in the ballpark.
That said, I have heard that women may find a wider window of eating to be more favorable when doing daily intermittent fasting. While men will typically fast for 16 hours and then eat for 8 hours, women may find better results by eating for 10 hours and fasting for 14 hours. The best advice I can give anyone, not just women, is to experiment and see what works best for you. Your body will give you signals. Follow what your body responds favorably to.
The purpose of fasting is never explicitly stated in Scripture but its connection to penitence, mourning, and supplication suggests a self-denial that opens one to God and to the immaterial aspects of life. Inasmuch as food and drink typify life in the flesh and all its demands and satisfactions, their absence or rejection speaks to the reality of a higher dimension, one in which the things of the spirit predominate. The theology of fasting, then, is a theology of priorities in which believers are given the opportunity to express themselves in an undivided and intensive devotion to the Lord and to the concerns of the spiritual life.

One reason experts tell people not to cut way back on calories is that it can slow your metabolism, making it even harder to lose weight. But studies show that fasting from time to time can be an effective strategy for weight loss. In addition, cutting calories on a couple of days instead of every day may help preserve muscle, so you lose mostly fat.

For example, in the graphic below you would eat dinner on Monday night and then not eat again until Tuesday evening. On Wednesday, however, you would eat all day and then start the 24–hour fasting cycle again after dinner on Wednesday evening. This allows you to get long fast periods on a consistent basis while also eating at least one meal every day of the week.
6. Are you hungry all the time? A scale of 1 to 10 is helpful in moments like this. One is ravenous, while 10 is extremely full. What is your number before and after meals? What is your number at moments during the fast? While hunger may be part of a fast given the caloric restriction, it shouldn’t be constant, ongoing and terrible. Also, notice portions when eating. If you haven’t created the right balance, you might overeat when breaking a fast, which is hard on your digestion and metabolism. Ideally, once acclimated, you’d stay within the 3 to 7 range at all times, 3 when fasting and 7 after meals.
Abstinence from food and/or drink as an element of private or public religious devotion. Fasting is nowhere commanded in the Torah and, in fact, is never attested earlier than the time of the judges of Israel (cf. Judges 20:26 ). The fact that Jesus and the disciples sanctioned it by their own example ( Matt 4:2 ; Acts 13:2-3 ), however, is sufficient justification for its practice in biblical times and, in fact, in modern times as well.
Hi I just started OMAD or 24-HIIT fasting. But I found myself eating more calories than eating 3 meals a day, I used to eat around 1300cal per day but now around 1500cal. I wonder if I’ll gain weight this way. I read some articles and they said if I start eating at dinner time, I should just eat the amount I usually eat for dinner like 500cal. I wonder if that is right.
Now there's certainly an issue of food that is associated with many seasons of prayer and fasting, and let me quickly add this: control of eating is a valid reason to fast. The purpose is not the number of pounds you might lose during a fast, but rather, trusting God to help you regain mastery over food during a fast. Jesus said, "The spirit is . . . willing, but the flesh is weak" (Matt. 26:41). Fasting is a means of bringing the flesh into submission to the Lord so He can strengthen us in our mastery over our own selves. Fasting in the flesh makes us stronger to stand against the temptations of the flesh. Those temptations very often deal with food.
Every person I know needs a breakthrough in some area of his or her life. I am no exception. I need breakthroughs all the time -- it may be a breakthrough in understanding a situation, a breakthrough answer to a problem, a breakthrough idea, a breakthrough insight, a breakthrough in financial or material provision, a breakthrough in health. If you have any need in your life, you need a breakthrough from God to meet that need! Fasting and prayer break the yoke of bondage and bring about a release of God's presence, power, and provision.
Dr. Michael Mosley popularized this variation of intermittent fasting in his book ‘The Fast Diet’. This involves 5 regular eating days and 2 fasting days. However, on these two fasting days, it is permitted to eat 500 calories on each day. These calories can be consumed at any time during the day – either spread throughout the day, or as a single meal.

Peipert was 48, stood at 5 feet, 5 inches, and weighed 174 pounds. During the trial, he cut his daily food intake from 3,300 to 2,475 calories, and his weight dropped to 147 pounds. His health biomarkers, especially his blood pressure, were excellent. “It was a remarkable drop in blood pressure. That taught me that, for our health, if we were just a little thinner, we’d be better off,” says Peipert, a gynecologist and researcher at the Indiana University School of Medicine.
If we are to learn the lost art of fasting and enjoy its fruit, it will not come with our ear to the ground of society, but with Bibles open. Then, the concern will not be whether we fast, but when. Jesus assumes his followers will fast, and even promises it will happen. He doesn’t say “if,” but “when you fast” (Matthew 6:16). And he doesn’t say his followers might fast, but “they will” (Matthew 9:15).
What makes fasting seem so novel is that, with all the diet advice out there, the easiest might be to simply not eat. Of course, fasting isn’t the same as starving yourself, which is what many people think when they hear “fasting.” And yet, fasting isn’t a diet, either. The literal definition of fasting is to abstain from food and drink from a specific period of time; it’s been around for thousands of years, as spiritual fasting is a part of many religions. But in this context, I prefer looking at fasting as simply a change in eating patterns.
Once you start your IF journey, you’ll most likely find that you feel fuller longer and can keep the meals you do eat very simple. There are a few different ways you can fast, so I broke up each of the different plans below into beginner, intermediate, and advanced along with a typical meal plan for each day. The combination of nutrients will give you the energy you need to enhance the benefits of your fasting journey. Just make sure to take into account any individual food intolerances, and use this as a guide for your particular health case, and adjust from there.

Pray before your fast. Pray, confessing every one of your sins, and inviting the Holy Spirit to lead your life. Let Jesus know you wish to know Him personally. Acknowledge that He lived without sin, died in our place, on the cross for our sins and rose 3 days later, freeing us from condemnation, and giving us His free gift of eternal life. Humble yourself to ask forgiveness from everyone you have hurt; ask forgiveness from God. Forgive those who have hurt you. You do not want to enter into a fast holding grudges, carrying envy, pride, anger or hurt. The enemy will try to use those things to distract you from your fast.

Fasting can be used for nearly every chronic condition, including allergies, anxiety, arthritis, asthma, depression, diabetes, headaches, heart disease, high cholesterol, low blood sugar, digestive disorders, mental illness, and obesity. Fasting is an effective and safe weight loss method. It is frequently prescribed as a detoxification treatment for those with conditions that may be influenced by environmental factors, such as cancer and multiple chemical sensitivity. Fasting has been used successfully to help treat people who have been exposed to high levels of toxic materials due to accident or occupation. Fasting is thought to be beneficial as a preventative measure to increase overall health, vitality, and resistance to disease. Fasting is also used as a method of mental and spiritual rejuvenation.

Martin Luther, founder of the Lutheran Churches, held that fasting served to "kill and subdue the pride and lust of the flesh".[63] As such, the Lutheran churches often emphasized voluntary fasting over collective fasting, though certain liturgical seasons and holy days were times for communal fasting and abstinence.[64][65] Certain Lutheran communities advocate fasting during designated times such as Lent,[37][66] especially on Ash Wednesday and Good Friday.[39][37][67][68] A Handbook for the Discipline of Lent delineates the following Lutheran fasting guidelines:[69]
