And there are many plans, because there are many schools of thought about what’s considered fasting, what food or drink should be consumed during eating windows, and how long these windows should last. Here are a few of the most common methods: Intermittent fasting means eating normally four or five days a week and consuming minimal calories on two or three nonconsecutive days. Time-restricted eating requires setting a window for consuming food, such as 7 a.m. to 7 p.m, and having nothing but noncaloric liquids the rest of the time. The “fasting mimicking diet” involves eating a small number of calories daily for a specific period of time — say five consecutive days every other month. These protocols all have benefits and drawbacks. One approach may work well for some while being entirely unsustainable for others.
The physiology of fasting has been widely studied and documented by medical science. Beneficial effects such as lowered cholesterol and improved general functioning have been shown. Fasting as a treatment for illness and disease has been studied less, although some studies around the world have shown beneficial results. A 1984 study showed that workers in Taiwan who had severe chemical poisoning had dramatic improvement after a ten-day fast. In Russia and Japan, studies have demonstrated fasting to be an effective treatment for mental illness. Fasting has been featured on the cover of medical journals, although mainstream medicine has generally ignored fasting and detoxification treatments as valid medical procedures.

The Good Friday fast became the principal fast in the calendar, and even after the Reformation in Germany many Lutherans who observed no other fast scrupulously kept Good Friday with strict fasting.


Many physiological changes occur in the body during fasting. During the first day or so, the body uses its glycogen reserves, the sugars that are the basic energy supply. After these are depleted, the body begins using fat. However, the brain, which has high fuel requirements, still needs glucose (sugars converted from glycogen). To obtain glucose for the brain, the body begins to break down muscle tissue during the second day of the fast. Thus, during fasting some muscle loss will occur. To fuel the brain, the body would need to burn over a pound of muscle a day, but the body has developed another way to create energy that saves important muscle mass. This protein-sparing process is called ketosis, which occurs during the third day of a fast for men and the second day for women. In this highly efficient state, the liver begins converting stored fat and other nonessential tissues into ketones, which can be used by the brain, muscles, and heart as energy. It is at this point in the fast that sensations of hunger generally go away, and many people experience normal or even increased energy levels. Hormone levels and certain functions become more stable in this state as well. The goal of most fasts is to allow the body to reach the ketosis state in order to burn excess fat and unneeded or damaged tissue. Thus, fasts longer than three days are generally recommended as therapy.
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.
Dear Adrian, I'm back after several months off on again off again tries. I actually did lose a total of 12 lbs. I started out at around 152 lbs and within a month & a half I was dropped down to 140! I was so happy... But unfortunately I over did an exercise routine of yours so badly I was unable to walk without pain shooting up my legs. ABSOLUTELY NO FAULT OF YOURS! I am the idiot for getting so excited about losing weight I got the attitude of " the more , the better" I advice to anyone don't ever over do anything cause it will have repercussions!! Long story short - after the awful pain I brought on my body I gave up on everything! It took a while to gain the lbs back but unfortunately it is now the end of September 2018 & I'm not only back to 150lbs but more like 158!!! I have started back with Adrian's trusted program & I pray I don't give up or ever, ever OVER DO IT!! I will keep you posted!
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.
That’s what happened to me. I was in ketosis for a year, lost 125lbs, but then I started eating again and poof, back came 90 of the 125 pounds 🙁 I’m finding it more difficult to get back into the swing of eating under 20 carbs a day. I find myself starving, or carb starved as it’s called, and it’s proving to be difficult, even with the meal replacement drinks. I’m going to try this fasting and see if that will help me get back to skinny, but be able to keep it off.
Sounds like your problem was going back to the way you use to eat. Maintaining weight lose is simple. Eat clean and portion your food and exercise a few times a week. Stay away from all fast food, high carb foods, lower alcohol intake and sugar. If anyone thinks that they can just go back to their old ways after losing weight, they are just plain crazy. People get fat for a reason so why would anyone think it wont come back without a permanent lifestyle change.
Before you start your IF plan, it's important to talk with a professional to make sure it's right for you. Women should be especially cautious as there are some mixed opinions on whether or not certain fasting protocols are healthy for female hormone balance. In addition, if you have adrenal fatigue or gut health issues you'll want to proceed with caution. If you have a history of disordered eating, you'll probably want to avoid fasting altogether..
The Church of the East strictly observes the Nineveh Fast (Som Baoutha). This annual observance occurs exactly three weeks before the start of Lent. This tradition has been practised by all Christians of Syriac traditions since the 6th century. At that time, a plague afflicted the region of Nineveh, modern-day northern Iraq. The plague devastated the city and the villages surrounding it, and out of desperation the people ran to their bishop to find a solution. The bishop sought help through the Scriptures and came upon the story of Jonah in the Old Testament. Upon reading the story, the bishop ordered a three-day fast to ask God for forgiveness. At the end of the three days, the plague had miraculously stopped, so on the fourth day the people rejoiced.
The ancient Greek physician Hippocrates wrote, “To eat when you are sick, is to feed your illness”. Another ancient Greek writer and historian Plutarch is also credited with penning “Instead of using medicine, better fast today”. In more recent times one of our founding fathers, Benjamin Franklin, stated, “The best of all medicines is resting and fasting”.

We are wise to recognize that food was the enticement the devil used to cause Eve and Adam to sin in the Garden of Eden. In Genesis 2 the Lord God told Adam and Eve that they could eat freely of every tree in the garden of Eden, "but of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die" (Gen. 2:17). God did not tell Adam and Eve to refrain from touching a particular animal or smelling a particular flower or swimming in a certain stream. He told them to refrain from taking a particular fruit into their bodies-one type of fruit out of all the many types He had made available to them.
Although certain benefits of caloric restriction have been demonstrated in animal studies, similar benefits of intermittent fasting in humans have not been observed. It is unclear that intermittent fasting is superior to other weight loss methods in regards to amount of weight loss, biological changes, compliance rates, and decreased appetite. Certain people who typically eat one or two meals a day or do not eat for long stretches of time may show better compliance with this type of regimen.
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]
How It Works: Fast for 24 hours once or twice per week. During the 24 hour fast, which creator Brad Pilon prefers to call a “24 break from eating,” no food is consumed, but you can drink calorie-free beverages. After the fast is over, you then go back to eating normally. “Act like you didn’t fast,” Pilon says. “Some people need to finish the fast at a normal mealtime with a big meal, while others are OK ending the fast with an afternoon snack. Time it however works best for you, and adjust your timing as your schedule changes,” he says.

Fasts must be entered and exited with care. To enter a fast, the diet should be gradually lightened over a few days. First, heavy foods such as meats and dairy products should be eliminated for a day or two. Grains, nuts, and beans should then be reduced for several days. The day before a fast, only easily digested foods like fruits, light salads, and soups should be eaten. During the fast, only pure water and occasional herbal teas should be drunk.
Insulin rises when we eat, helping to store the excess energy in two separate ways. Sugars can be linked into long chains, called glycogen and then stored in the liver. There is, however, limited storage space; and once that is reached, the liver starts to turn the excess glucose into fat. This process is called De-Novo Lipogenesis (meaning literally Making Fat from New).
Side effects of fasting include dizziness, headaches, low blood sugar, muscle aches, weakness, and fatigue. Prolonged fasting can lead to anemia, a weakened immune system, liver and kidney problems, and irregular heartbeat. Fasting can also result in vitamin and mineral deficiencies, muscle breakdown, and diarrhea. When you drink laxative concoctions during a fast, there is an increased risk of fluid imbalance and dehydration.
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.
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.
^ Guéranger, Prosper; Fromage, Lucien (1912). The Liturgical Year: Lent. Burns, Oates & Washbourne. p. 8. 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.
Now, intermittent fasting isn’t magical—your calories still count. It’s just an alternate way to reach that same calorie restriction, says Grant Tinsley, Ph.D., C.S.C.S., an intermittent fasting researcher and assistant professor of exercise physiology at Texas Tech University. “With traditional calorie restriction, you’re following a normal, healthy eating pattern but eating less at each meal. With intermittent fasting, you’re eating roughly the same number of reduced calories, just in a confined time frame. You’re just giving yourself different parameters to live within.”
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).

This is the same as the 8-to-6 window plan, but you are extending your fasting time an extra four hours. I personally practice this plan during the workweek. I'm not a breakfast person, so I just enjoy a few cups of herbal tea to start my day. With this plan you will be eating only between the hours of 12 p.m. and 6 p.m. for a full 18 hours of fasting within a 24-hour period.


You also want to avoid the counting calories and calorie restriction fallacies. Most people fail to appreciate that there are many intricate biochemical dynamics that occur that are unaccounted for when you just count "calories in and calories out." While animals like rats can achieve a 40 percent increase in longevity through lifelong calorie restriction, such a great effect is not seen in humans, and there are good reasons for that. As pointed out by Fight Aging:14
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.
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.
Dietrich Bonhoeffer, in his book The Cost of Discipleship, said, “Jesus takes it for granted that His disciples will observe the pious custom of fasting. Strict exercise of self-control is an essential feature of the Christian life. Such customs have only one purpose — to make the disciples more ready and cheerful to accomplish those things which God would have done.”
The drawbacks were clear. The men became obsessed with food to the exclusion of everything else in their life, and when the calorie restriction ended, they all over-reacted. Within a few weeks, they regained all of the lost weight plus about 10 percent more. Other studies have come to similar conclusions. So starvation-type diets may not be ideal for the average person. Your body will tend to shut down various processes in order to survive. For example, by reducing thyroid function, your body will not burn as many calories.
The Hebrew verb sum [Wx] is the only one used to describe fasting as a religious exercise. It (and its cognate noun som [/x]) conveys the explicit meaning "to abstain from food" and thus occurs regularly as a technical religious term. The Greek verb nesteuo [nhsteuvw] and its companion noun nesteia [nhsteiva] occur consistently in the Septuagint as translations of Hebrew sum [Wx] and som [/x] and as the usual terms for fasting in the New Testament.
Even though this plan is advanced, it's very simple. Don't eat anything every other day. This is the most intense form of fasting but can produce amazing results. Every other day, eat healthy fats, clean meat sources, vegetables, and some fruit, and then on your fasting days, you can consume water, herbal tea, and moderate amounts of black coffee or tea.

According to a research published in Cell Metabolism, fasting for 12+ hours most days may promote weight loss, prevent disease and promote longevity. The researchers, who divided the mice into four diet groups and categorised them into different feeding schedules, found that mice fasted for at least 12 hours and kept their eating within a set 12-hour time frame experienced significant weight loss compared to mice eating the same diet but with liberty to eat all day long. 
I hope this encourages someone. This morning I got into an argument with someone. (that isn't the encouraging part of course) I became so discouraged and did not want to go to my office and try to talk with God about anything at that point. And I wanted a cup of coffee but tried to stay away. Finally I felt the Lord say to me that if a cup of coffee was going to keep me from spending time with Him then have the cup of coffee. I made my cup, went to my office and logged into pastor Jentezen's blog. And I cried and cried. I just couldn't pray but I could listen. I clicked on his sermon, "Right People, Right Place, Right Plan" and God said some of the sweetest and most encouraging things in that sermon. Please stick to and fight through your fast but don't let anything you feel is a slip up keep you from what's really important. If I had let that cup of coffee make me feel unworthy of seeing God this morning then I would have been out of the biggest blessing of hearing His Words to me.
Snacking throughout the day can be a major source of calories you don’t need and is often the ultimate pitfall for dieters. Make sure you stick to your fast by only eating three designated meals a day and leaving the extra snacks out of the equation. Cutting the excess sugar, carbs, and calories not only helps you lose weight but also helps your body become healthier too.

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.

Still, researchers are exploring whether fasting might help fight cancer, or help cancer patients tolerate chemotherapy. And they’re putting serious thought into whether fasting has a role in treating and preventing diabetes, cardiovascular disease, and multiple sclerosis. But while the animal literature is rich, the literature in humans is promising — though far from conclusive. As this 2017 review of the science found, the studies on fasting to control Type 2 diabetes come to contradictory results, and there’s “minimal data” comparing the effects of fasting to plain old calorie restriction in overweight or obese people with the disease. There were also no studies on fasting and human cancer rates.


All of this may seem hopelessly contradictory. On the one hand, calorie restriction promotes beneficial biological changes that tend to extend life; on the other, there are built in mechanisms that when triggered by chronic calorie restriction can trigger other health problems. These are complex issues, and any extreme measure is likely to cause more problems than it solves.
You’ll run out of energy. When you don’t have anything in your system for several hours, your blood sugar will eventually drop below baseline. If you’ve ever had a blood sugar crash, you know how this state feels. Sleepiness, trouble focusing, lightheadedness, intense cravings, and the occasional mood swing typically accompany low blood sugar. Your cells run low on fuel and they start demanding that you give them more carbs.[13]
Fasting is a practice in several Christian denominations and is done both collectively during certain seasons of the liturgical calendar, or individually as a believer feels led by the Holy Spirit.[35] In Western Christianity, the Lenten fast is observed by many communicants of the Catholic Church, Lutheran Churches, Methodist Churches, Reformed Churches, Anglican Communion, and the Western Orthodox Churches and is a forty-day partial fast to commemorate the fast observed by Christ during his temptation in the desert.[36][37] While some Western Christians observe the Lenten fast in its entirety, Ash Wednesday and Good Friday are nowadays emphasized by Western Christian denominations as the normative days of fasting within the Lenten season.[38][39]
