Whole-day fasting involves regular one-day fasts. The strictest form would be alternate day fasting (ADF). This involves a 24-hour fast followed by a 24-hour non-fasting period. The alternate day modified fasting (ADMF) and 5:2 diets—the latter defined as five days per week not fasting and two days per week either total fasting or modified fasting—both allow the consumption of approximately 500–600 calories on fasting days.[1][3]
In a 2011 study published by the American Association for Cancer Research, researchers at Genesis Prevention Center at University Hospital in South Manchester, England tested the effects of three kinds of diets on 115 women. One diet looked like the Fast Diet (five days of normal eating and two days following a calorie-restricted, low-carb diet each week), another restricted carbs two days a week but had no calorie restrictions and a final group followed a calorie-restricted Mediterranean diet for all seven days of the week. After four months, participants following the intermittent low-carbohydrate diets lost an average of 9 pounds, while those on the Mediterranean diet lost an average of 5 pounds.

Once when the Buddha was touring in the region of Kasi together with a large sangha of monks he addressed them saying: I, monks, do not eat a meal in the evening. Not eating a meal in the evening I, monks, am aware of good health and of being without illness and of buoyancy and strength and living in comfort. Come, do you too, monks, not eat a meal in the evening. Not eating a meal in the evening you too, monks, will be aware of good health and..... living in comfort.[25]
Through evolution, the body became very efficient at storing energy and handling situations when no food was available. For many centuries, fasting was probably a normal occurrence for most people, and the body adapted to it. It is estimated that even very thin people can survive for 40 days or more without food. The body has a special mechanism that is initiated when no food is eaten. Fasting is not starvation, but rather the body's burning of stored energy. Starvation occurs when the body no longer has any stored energy and begins using essential tissues such as organs for an energy source. Therapeutic fasts are stopped long before this happens.

Hey! I've been following this site for a while but I'm so busy that I've never been able to get around to a lot of this. I'm a 17 year old female in high school, and I take college level classes and work a lot after school, so I'm constantly busy between work, homework, and school itself. I also lack willpower a lot, which I think is why I struggle to lose weight so much. With such a busy schedule and such little willpower, what do you think would be the best way for me to lose weight and rather quickly (though healthily)? I'm 5'5 and I weigh 240 pounds.
"I also discourage the idea of fasting for those who struggle with eating disorders that are making intake of food a challenge and concern in their daily living. The point of the fast is to combine it with a more intense, focused time of prayer that brings a greater communion with God, a greater empowerment of the Spirit, and a greater earnestness in your soul.”
Fasts may last for varying lengths of time -- one day, three days, seven days, and more. We should prayerfully seek the Lord about the length of our fast. Fasting should have an object in mind; we should have a clear idea of the need and purpose. One of the most pressing reasons for Christian fasting may be revival -- “Will you not revive us again...” (Psalm 85:6).

Biblical fasting, unlike fasting for medical or health reasons, must be done with an attitude of seriousness and sincerity. When we fast, we willingly deprive the body of nourishment and the pleasurable taste of food. The body requires food for sustenance; therefore our hearts and minds must be totally focused and directed towards God so that He may be the full source of our strength during our period of fasting.


In a sense, everyone fasts. When we are in bed asleep, we go without any food or drink. That is fasting. That is why the first meal of the day is called breakfast. However, when people speak of fasting, they usually mean a longer period of time of deliberately choosing not to eat and drink. It can be for a whole day, part of a day or more than a day.
Fasting proponents will also note that there’s a long tradition of religious fasting, though the focus there tends to be more spiritual than health-oriented. “Many religious groups incorporate periods of fasting into their rituals,” this article points out, “including Muslims who fast from dawn until dusk during the month of Ramadan, and Christians, Jews, Buddhists, and Hindus who traditionally fast on designated days of the week or calendar year.”

If you're looking to lose weight, this isn't a problem. And even if you're happy with your weight, this won't prove to be too much of an issue if you follow the daily fasting or weekly fasting schedules. However, if you're fasting for 24 hours per day on multiple days per week, then it's going to be very difficult to eat enough of your feast days to make up for that.
The combination of fasting and praying is not a fad or a novelty approach to spiritual discipline. Fasting and praying are not part of a human-engineered method or plan. They are not the means to manipulate a situation or to create a circumstance. Fasting and praying are Bible-based disciplines that are appropriate for all believers of all ages throughout all centuries in all parts of the world.
As you pray and fast, you will call on God, and He will answer you. Answered prayer is the quintessence of praying and fasting. If I were to share with you the five or six pages of the prayer journal I prepared prior to my first forty-day fast, and then walk you back through my journal since then, you would see one thing: My prayers were answered. They are still being answered. There is something to the disciplines of prayer and fasting. I could point you to every experience of long-term fasting where God has answered my requests before Him. This does not mean they were answered as I preferred, but it did not matter. He had worked in my heart, and I was released, fully confident that God was ordering my way. When we humble ourselves before the Father, and when God sees we are serious about giving Him our broken spirits, He begins to do things we have never seen before. It’s empowering. It sensitizes us to the needs of others at home and overseas as we suddenly find ourselves quietly praying for people, events, and situations with the knowledge that our prayers not only will be heard but that the Father will answer them.
How It Works: This one’s easy: Eat very little one day, and eat like normal the next. On the low-calorie days, that means one fifth of your normal calorie intake. Using 2,000 or 2,500 calories (for women and men, respectively) as a guide, “fasting” (or “down”) day should be 400 to 500 calories. Followers can use this tool to figure out how many calories to consume on “low-calorie” days.

New Delhi: As more and more people are trying to lose weight, intermittent fasting (IF) continues to be one of the most popular fitness trends across the world. Studies have shown that IF can be a powerful weight loss tool that can effectively help you fight belly fat while also improving health in many ways. It is claimed that it can benefit your brain health, reduce your risk of certain conditions - such as diabetes, heart disease, cancer, - and may even help you live a longer life.
But followers beware, says nutrition researcher Michelle Harvie. Dieters going keto tend to lose weight, but the diets are low in fiber and high in saturated fat, which is a risk for cardiovascular disease. “And there is increasing evidence that its effect on the gut microbiome is pretty adverse,” says Harvie. “The gut microbiome is a poorly understood but potentially important part of our metabolic health. And if you mess that up, you’re in trouble.”

Before beginning your fast, decide when you’re eating and what you’ll be eating then. Knowing this in advance takes the pressure off, especially if you feel like you may eat everything in sight “because you can.” As you become more used to fasting, you might find it’s unnecessary to sort out meals beforehand, but I find having a range of healthy food waiting for me in the fridge makes fasting a lot easier.

In this example, lunch on Monday is your last meal of the day. You then fast until lunch on Tuesday. This schedule has the advantage of allowing you to eat everyday of the week while still reaping the benefits of fasting for 24 hours. It's also less likely that you'll lose weight because you are only cutting out two meals per week. So, if you're looking to bulk up or keep weight on, then this is a great option.


Fasting has been found to have positive effects on body mass as well as other health markers in professional athletes. This is because, as previously mentioned, fasting can effectively shed excess fat, while optimizing muscle growth, because of HGH production. Traditionally, athletes are advised to consume high-quality protein half hour after finishing their workouts (post-workout nutrition) to simultaneously build muscle and reduce fat. Fasting is advised for training days, while eating is encouraged on game days.
The digestive tract is the part of the body most exposed to environmental threats, including bacteria, viruses, parasites, and toxins. It requires the most immune system support. When food is broken down in the intestines, it travels through the blood to the liver, the largest organ of the body's natural detoxification system. The liver breaks down and removes the toxic by-products produced by digestion, including natural ones and the chemicals now present in the food supply. During fasting, the liver and immune system are essentially freed to detoxify and heal other parts of the body.
That’s the principle behind the diet method known as intermittent fasting. Unlike many popular diets, intermittent fasting has the backing of scientific research (including a massive 2017 study analysis by the International Society of Sports Nutrition), which suggests that intermittent fasting is just as effective as daily calorie restriction—sometimes better—at improving body composition. Furthermore, intermittent fasting doesn’t involve any calorie counting, and may suppress hunger better than traditional low-calorie diets.

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.


The general idea behind the 5:2 diet is calorie restriction on the two (non-consecutive) given days. That is, for two of the 7 days in each week, you eat very low calorie (but high in nutrition) foods, while the other 5 days you can eat what you would usually eat. This diet isn’t a full fast (as in water only), but is a carefully planned eating plan for a couple of days each week.
These types of side effects weren’t more common in CR dieters overall, but several people had to pull out of the study because of safety concerns. Noted side effects of CR are chronic loss of bone density and lean body mass, and excessive weight loss. Some CR dieters have body mass indexes in the teens, which suggest malnutrition and frailty, Longo says.
I have found that the 4:3 style fasts have worked well for my friends and me based on our work/life schedule and our personal health goals. I like that full day fasts feel like an on/off switch — I don’t think about eating on fast days and on eat days if I happen to overeat, I don’t feel guilty about it (since I’m eating at a deficit during the week). I find it more manageable to cut calories over a week (using the 4:3 style of IF) instead of every day (trying to eating less daily).
In terms of your comment regarding water yes millions of people may do this and as you say it has little impact and harm. I however prefer to drink water on a regular basis; it is what the body is primarily made up of and what the cells need for repair and regeneration. That and because many of us often think we are hungry when in fact we are dehydrated and the body is wanting more water – wanting more fluids this is why I encourage people to drink more water during fasting days than do a total fast.

In her blog, Gospel Taboo, Amanda Edmondson writes, "Biblically, fasting is mentioned in both the Old and New Testament. In the Old Testament it was often a way of expressing grief or a means of humbling one's self before the Lord. In Psalm 35:13, David humbled himself with fasting. In the New Testament it was a means to grow closer to God through mediating and focusing on Him. In Matthew 4:1-2, Jesus went to the wilderness to fast for 40 days. In Matthew 6:16-18 we learn that we aren’t to look somber while fasting so that it’s not obvious to others when we are fasting. Throughout the New Testament fasting and prayer are often mentioned together. In Acts 13:3, ‘they had fasted and prayed.’ In Luke 2:37 a widow worshiped day and night fasting and praying."
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.
Seeking God's will in special circumstances requires special time with God. Fasting to God proves acknowledgment of your personal weakness and dependence on Him. The first step to any fast is admitting your need for God. Giving up food is an outward action for an inward commitment. Ezra 8:23 says, "So we fasted and petitioned our God about this, and he answered our prayer." Fasting for God requires sacrifice and discipline.
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.
