As a whole, however, fasting appears to be a private matter in the Bible, an expression of personal devotion linked to three major kinds of crisis in life: lamentation/penitence, mourning, and petition. Without exception it has to do with a sense of need and dependence, of abject helplessness in the face of actual or anticipated calamity. It is in examining these situations that the theological meaning and value of fasting are to be discovered.

Yes, by cutting out an entire meal each day, you are consuming fewer calories per week – even if your two meals per day are slightly bigger than before. Overall, you’re still consuming fewer calories per day. This is highlighted in a recent JAMA study[b] in which both calorie restricted dieters and intermittent fasters lost similar amounts of weight over a year period.


Still, it's important to note that the results of intermittent fasting are no better than a calorie-restricting diet. A 2017 study in JAMA showed that alternate-day fasting doesn't produce superior benefits for weight loss than daily calorie restriction, and similar conclusions were drawn in a 2018 study published in the American Journal of Clinical Nutrition. So if you don't think fasting is right for you, restricting calories works just as well.
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.
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.
Reduces inflammation: Lowering inflammation is key to losing weight, boosting longevity, and reducing your risk of major illnesses such as Alzheimer’s and cancer. That’s why it’s at the core of the Bulletproof Diet. Intermittent fasting decreases oxidative stress and inflammation across the board, including inflammatory markers such as adiponectin, leptin, and brain-derived neurotrophic factor.[9]
What and when you eat during the feeding window also depends on when you work out. On days you exercise, carbs are more important than fat. On rest days, fat intake should be higher. Protein consumption should be fairly high every day, though it will vary based on goals, gender, age, body fat and activity levels. Regardless of your specific program, whole, unprocessed foods should make up the majority of your calorie intake. However, when there isn’t time for a meal, a protein shake or meal replacement bar is acceptable (in moderation).
The trial, which aimed to investigate how food deprivation affects the aging process, involved 218 normal and slightly overweight men and women between the ages of 21 and 51. Of the group, 143 of them were tasked with following CR, eating 25 percent fewer calories than usual — a decrease deemed feasible based on animal studies. They were to keep this regimen for two years with help from a behavioral intervention team and dietitians to make sure they were getting basic nutrition.

This mirrored some of what researchers were finding in non-human primates. Rhesus monkeys share 93 percent of their genetic makeup with humans and usually live to about 26 in captivity. In one study on 76 rhesus monkeys that’s been running since 1989 at the Wisconsin National Primate Research Center, monkeys on a 30 percent calorie cut lived, on average, two to three years longer than control monkeys. Another ongoing study, started in 1987 by the National Institute on Aging on 121 rhesus monkeys, hasn’t detected the same boost to longevity. But CR has worked remarkably well for the 10 males that started the diet later in life. At least four have lived past age 40, including one to 43 — a record for the species.
Hunger suppression. A ketogenic diet suppresses hunger, too.[16] On a keto diet, your liver turns fat into little bundles of energy called ketones, which it then sends through your bloodstream for your cells to use as fuel. Ketones suppress ghrelin, your body’s main hunger hormone.[17] High ghrelin makes you hungry. On keto, your ghrelin stays low, even when you don’t have food in your system. In other words, you can go longer without eating and you won’t get hungry. Fasting becomes significantly easier on keto so you can fast for longer windows to reap all the benefits.
If you have an addictive relationship with food and you struggle with portion control, track your calorie intake in your meals to make sure you’re not overeating. If you skip breakfast, you might be so hungry from this that you OVEREAT for lunch and this can lead to weight gain. Again, the important thing here is that with intermittent fasting you’re eating fewer calories than normal because you’re skipping a meal every day.
Pros: According to the founders, while everyone is technically fasting every day — during the hours when we’re not eating — most of us do so haphazardly, which makes it harder to reap the rewards. Fat Loss Forever offers a seven-day schedule for fasting so that the body can get used to this structured timetable and reap the most benefit from the fasting periods. (Plus, you get a full cheat day. And who doesn’t love that?)
I am not against people fasting in order to lose weight. Many people fast to lose weight or maintain their weight.What I am opposed to is making the losing of weight your primary goal in a season of spiritual fasting and prayer. To have weight loss as a goal makes your fasting a diet plan, not a time of genuine fasting and prayer. If losing weight is your purpose in fasting, you will be missing out on the full reason for fasting, and you likely will be concerned only with what you don't eat rather than with what you are led to pray.
Often when we slip up on a fast, we can let ourselves feel condemned and defeated. Breaking your fast in NOT a sin. If anything, you’ve proven your humanity, and 2 Corinthians 12:9 states that, “My strength is made perfect in weakness” (NKJV). God’s strength often shows up in our weakest moments. Don’t let a momentary lapse define your fast. We’re not pushing towards our stomach, we’re not even pushing to ourselves, but we are pushing to be closer to God.
There are many promises God makes in His Word in regard to the blessings we will receive through prayer and fasting. In my book The Power of Prayer and Fasting, I talk about seven specific promises. I want to mention three of them here that I trust will bless you as you read. I have seen each of these promises come true in my walk with God, and I’m confident they also can live in you, through you, and will be yours as you call on God to do His will in your life.
A randomized controlled trial that followed 100 obese individuals for one year did not find intermittent fasting to be more effective than daily calorie restriction. [6] For the 6-month weight loss phase, subjects were either placed on an alternating day fast (alternating days of one meal of 25% of baseline calories versus 125% of baseline calories divided over three meals) or daily calorie restriction (75% of baseline calories divided over three meals) following the American Heart Association guidelines. After 6 months, calorie levels were increased by 25% in both groups with a goal of weight maintenance. Participant characteristics of the groups were similar; mostly women and generally healthy. The trial examined weight changes, compliance rates, and cardiovascular risk factors. Their findings when comparing the two groups:
The problem is that too many people jump on the fasting bandwagon without understanding how to assess its impact. Once a plan has been integrated into your everyday life, you should take time every week or month to analyze how things are going. Even if weight loss is your primary goal, it’s important to consider how fasting is affecting other aspects of your health, such as your energy levels, ability to exercise and digestion. Here are some questions you should ask yourself.
“I used to crave foods like crazy when I first started,” says Dr. Sylvia Tara, author of The Secret Life of Fat, in a Bulletproof Podcast episode. “after six to eight weeks, I didn’t feel it anymore.” Dr. Tara kept a journal or foods and schedules to find how fasting worked for her. Her advice for weight loss with intermittent fasting? “For people who have those 20 pounds, know, number one, it can be done. Number two, it might be a bit more effort than you thought it was going to be… Third, know that it gets easier with time and you can maintain it. It really isn’t as bad once you get into it, and it’s extraordinarily effective.”
The competition ended in December 2011. I won the office pool — $220 cash. A lot of people have two big criticisms of dieting. One is that diets don’t tend to work. The other is that if a diet does work, the weight loss is temporary. People call this yo-yo dieting, in that you lose a few pounds, gain a few pounds, and often end up heavier than when you started.
Don’t forget that God loves you so much that He sent His only Son to die for you. His love is stronger than any thing you’ve ever done. When you decide to commit to fast, you’re going to want food. This isn’t abnormal, it happens to everyone. Unfortunately, for all of us, we’re human. Sometimes our stomach gets the best of us on a fast and we grab a bite of something we’re supposed to be fasting. This isn’t the end of everything. It doesn’t even have to be the end of your fast. Pick back up where you left off; we’re in a marathon not a sprint.

Understanding the potential adverse effects of intermittent fasting is limited by an inadequate number of rigorous clinical trials. One 2015 review of low-quality clinical studies found that short-term intermittent fasting may produce minor adverse effects, such as continuous feelings of weakness and hunger, headaches, fainting, or dehydration.[26] Long-term fasting may cause eating disorders or malnutrition, with increased susceptibility to infectious diseases.[26]
In Methodism, fasting is considered one of the Works of Piety.[52] The Discipline of the Wesleyan Methodist Church required Methodists to fast on "the first Friday after New-Year's-day; after Lady-day; after Midsummer-day; and after Michaelmas-day."[53] Historically, Methodist clergy are required to fast on Wednesdays, in remembrance of the betrayal of Christ, and on Fridays, in remembrance of His crucifixion and death.[54][55] "The General Rules of the Methodist Church," written by the founder of Methodism, John Wesley, wrote that "It is expected of all who desire to continue in these societies that they should continue to evidence their desire of salvation, by attending upon all the ordinances of God, such are: the public worship of God; the ministry of the Word, either read or expounded; the Supper of the Lord; family and private prayer; searching the Scriptures; and fasting or abstinence."[55] The Directions Given to Band Societies (25 December 1744) mandated fasting and abstinence from meat on all Fridays of the year,[53][56] a practice that was reemphasized by Phoebe Palmer and became standard in the Methodist churches of the holiness movement.[57][58] Wesley himself also fasted before receiving Holy Communion "for the purpose of focusing his attention on God," and asked other Methodist Christians to do the same.[55] In accordance with Scripture and the teachings of the Church Fathers, fasting in Methodism is done "from morning until evening"; John Wesley kept a more rigorous Friday Fast, fasting from sundown (on Thursday) until sundown (on Friday) in accordance with the liturgical definition of a day.[55][59] The historic Methodist homilies regarding the Sermon on the Mount also stressed the importance of the Lenten fast.[60] The United Methodist Church therefore states that:
Another plus is that this is easily the most sustainable eating plan I’ve ever come across. You don’t need to fast forever to maintain the benefits — you can fast for a time and stop when you reach your goal weight. But if your weight creeps up, you can add in one fasting day per week to head it off, rather than going into full-blown “emergency calorie-restriction” mode.
A randomized controlled trial that followed 100 obese individuals for one year did not find intermittent fasting to be more effective than daily calorie restriction. [6] For the 6-month weight loss phase, subjects were either placed on an alternating day fast (alternating days of one meal of 25% of baseline calories versus 125% of baseline calories divided over three meals) or daily calorie restriction (75% of baseline calories divided over three meals) following the American Heart Association guidelines. After 6 months, calorie levels were increased by 25% in both groups with a goal of weight maintenance. Participant characteristics of the groups were similar; mostly women and generally healthy. The trial examined weight changes, compliance rates, and cardiovascular risk factors. Their findings when comparing the two groups:
Time-restricted eating is pretty simple to implement. If you finish dinner at 7 p.m., for instance, you wouldn’t eat anything again until at least 7 a.m. If you wanted to take it further, you’d extend the no-eating time until about 11 a.m. or 12 p.m. Because you’re sleeping for a large chunk of the “no eating” time, this is a good way to introduce fasting into your lifestyle and experiment without any major changes.
Although it’s possible that fasting helps manage blood sugar and insulin, fight inflammation, and ease sleep problems, most people follow a fasting diet to lose weight. Fasting is believed to help in this goal because of the effects that caloric restriction and extended periods without food have on metabolism, or simply because people eat less during the restricted feeding window. (Some dieters benefit from the structure and clear boundaries fasting plans offer.)
Also, for many people, a full 16 hours of fasting just isn’t realistic, says Cynthia Sass, a New York City– and L.A.-based performance nutritionist. She recommends 12 hours of overnight fasting at most and believes the 16-hour gap is especially tough on those who exercise early in the morning or late at night. “If fasting makes you feel miserable and results in intense cravings and rebound overeating, it's not the right path for you,” she says.
The Bible also gives instructions about the attitude and approach we should have in fasting. Jesus warned about hypocritical fasting, trying to show off or make others feel sorry for us.In the New Testament, Anna, the prophetess, is described as serving God day and night with fasting and prayers (Luke 2:37). We read that John the Baptist taught his disciples to fast and Jesus Christ said His disciples would fast after His death (Mark 2:18-20). Paul and Barnabas prayed and fasted when they ordained elders in the Church (Acts 14:23). And Jesus Christ fasted 40 days and nights before facing Satan in an epic battle of spiritual will (Matthew 4:2).

Could you please recommend me to what workout i should do . I would like to lose 6-7 kgs for the first month .I am following your videos but i am confused which one to follow..I followed your 5 lbs in a week video for a couple of days and felt like burning fat and now i am seeking for your suggestion

It requires less time (and potentially less money). Rather than having to prepare or purchase three to six meals a day, you only need to prepare two meals. Instead of stopping what you’re doing six times a day to eat, you simply only have to stop to eat twice. Rather than having to do the dishes six times, you only have to do them twice. Rather than having to purchase six meals a day, you only need to purchase two.
There are a couple of other caveats here. Fasting diets require working through hunger, saying no to the bagels and muffins put out in your morning meeting or the food at your business lunch. So it’s no surprise that many people can’t stick to fasting diets long enough to keep the weight off. In another 2018 review of the literature on fasting’s impact on weight, the researchers note, “Dropout rates have been as high as 40 percent. Thus, despite the statistical significance of weight loss results, the clinical significance and practicality of sustaining an [intermittent fasting] regimen are questionable.”
Basically, the 12:12 plan is a type of intermittent fasting where you eat for 12 hours of the day and fast for the other 12 hours. This method requires you to limit your daily calorie intake within a 12-hour window (meaning 12 hours eating, 12 hours fasting), rather than eating whenever you want throughout the day. For instance, if you eat your evening meal or dinner at 8 p.m., you should have your breakfast around 8 a.m. the following morning while on this plan. The 12:12 is claimed to be the simplest type of intermittent fasting, especially for beginners who are trying to lose weight or simply want to improve health. Read - Weight loss: All you need to know about the 16:8 diet and 6 tips to burn belly fat using intermittent fasting

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.)

This is probably a good time to mention that while I have practiced intermittent fasting consistently for the last year, I'm not fanatical about my diet. I work on building healthy habits that guide my behavior 90% of the time, so that I can do whatever I feel like during the other 10%. If I come over to your house to watch the football game and we order pizza at 11pm, guess what? I don't care that it's outside my feeding period, I'm eating it.


Biblical fasting brings us into a closer union with God. While our bodies are being deprived for the purpose of drawing near to God, He has promised in return to draw near to us. This is a spiritual certainty. As we decrease, the Spirit increases. As individuals we are strengthened and renewed. “...Though outwardly we are wasting away, yet inwardly we are being renewed day by day” (2 Corinthians 4:16).

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.)

Fasting is often used as a tool to make a political statement, to protest, or to bring awareness to a cause. A hunger strike is a method of non-violent resistance in which participants fast as an act of political protest, or to provoke feelings of guilt, or to achieve a goal such as a policy change.[citation needed] A spiritual fast incorporates personal spiritual beliefs with the desire to express personal principles, sometimes in the context of a social injustice.[17]
