Yom Kippur is considered to be the most important day of the Jewish year-cycle and fasting as a means of repentance is expected of every Jewish man or woman above the age of bar mitzvah and bat mitzvah respectively. This is the only fast day mentioned in the Torah (Leviticus 23:26-32). It is so important to fast on this day, that only those who would be put in mortal danger by fasting are exempt, such as the ill or frail (endangering a life is against a core principle of Judaism). Those that do eat on this day are encouraged to eat as little as possible at a time and to avoid a full meal. For some, fasting on Yom Kippur is considered more important than the prayers of this holy day. If one fasts, even if one is at home in bed, one is considered as having participated in the full religious service.
Many people who want to try IF choose the 16:8 method because it allows you to eat whatever you want for an 8-hour window and then fast for 16 hours. During the fasting period, you can drink water, tea, coffee, and even diet soda. The trick is to figure out what 8-hour eating window works best for you. Are you fine with skipping breakfast? Or do you work out in the morning and prefer to forgo dinner? Experiment with the eating and fasting intervals that work best for you. However, like all restrictive diets, there are some drawbacks. For one, drinking caffeinated drinks while fasting can disrupt your circadian rhythm, and therefore, your metabolism.
As a functional medicine practitioner, I see a wide range of health problems that all stem from chronic inflammation. And while acute inflammation is a natural and healthy response to help fight off pathogenic bacteria and infections, long-term chronic inflammation that doesn’t subside when the threat is gone can contribute to everything from autoimmune conditions to cancer.
Jimmy Kimmel lost 25 pounds on the 5:2 diet, eating fewer than 500 calories on Mondays and Thursdays then eating whatever he wants the rest of the week. Actor Benedict  Cumberbatch also lost on the 5:2 diet while Hugh Jackman had a different intermittent fasting schedule. Each day he ate during an eight hour period but fasted for the remaining 16 hours. Is this just a Hollywood fad or are there real benefits to intermittent fasting?
American King James Version×). Jesus knew that His true disciples, once He was no longer there in the flesh with them, at times would need to fast to regain and renew their zeal to serve Him (Mark 2:18-20 Mark 2:18-20 18 And the disciples of John and of the Pharisees used to fast: and they come and say to him, Why do the disciples of John and of the Pharisees fast, but your disciples fast not? 19 And Jesus said to them, Can the children of the bridal chamber fast, while the bridegroom is with them? as long as they have the bridegroom with them, they cannot fast. 20 But the days will come, when the bridegroom shall be taken away from them, and then shall they fast in those days.
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.
Research more about IF and learn outside of what I share to see if there is a different style of IF that is a better fit for you and your needs. While there is widely available research on the benefits of IF, you should also learn more about the potential of negative effects of fasting on sleep, alertness, cognitive-motor performance, mood and for those with a previous history or susceptibility with eating disorders.
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.)
While these five methods are the most well-known in terms of integrating periods of fasting into your eating schedule, there are many other similar philosophies based on meal timing. For those who prefer a more fluid, less rigid method, there’s also the concept of eating intuitively. Primal Diet proponent Mark Sisson is a supporter of the Eat WHEN (When Hunger Ensues Naturally) method, where dieters simply eat whenever their bodies ask them to. However, some believe this can also lead to overeating or overconsumption of calories, since our bodies’ hunger-induced choices may be more caloric than otherwise.
When a feast day occurs on a fast day, the fast is often mitigated (lessened) to some degree (though meat and dairy are never consumed on any fast day). For example, the Feast of the Annunciation almost always occurs within the Great Lent in the Orthodox calendar: in this case fish (traditionally haddock fried in olive oil) is the main meal of the day.
Once or twice per week you can have a treat. Remember you will have 600-1000 calories to work with in the main meal. This should make it pretty easy to enjoy some of your favorite foods or go out to a restaurant with friends/family. Just make sure to not go over the calorie budget for the day. If you do end up going over the calorie budget for the day then you can compensate by slightly reducing calories the following days.
Jesus was teaching that after His departure, the entire dynamic would change and the disciples would need a different type of preparation and provision. Fasting was to be a vital part of this new preparation. The new covenant is based on the truth that we have received everything in Christ, “Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ” (Ephesians 1:3). 

Where diets complicate life, fasting simplifies. Where diets are expensive, intermittent fasting is free. Where diets can take time, fasting saves time. Where diets are limited, fasting is available anywhere. Where diets have variable efficacy, fasting has unquestioned efficacy. There is no more powerful method for lowering insulin and decreasing body weight.
This handy reference guide, Seven Basic Steps to Successful Fasting and Prayer, will help make your time with the Lord more spiritually rewarding. I encourage you to keep it with you during your fast and refer to it often because it gives easy-to-follow suggestions on how to begin your fast, what to do while you fast, and how to end your fast properly.

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.
As it turns out, the science behind these diets is still pretty nascent and exploratory — more than the acolytes might have you believe. While there’s lots of animal research, human studies on fasting are only just beginning to ramp up. And while we have learned that fasting helps people lose weight, it’s only if you can stick with it. But that doesn’t make fasting any less fascinating. Here’s what we know and don’t know.
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.
Additionally, various studies ( in both animals and humans) have shown that intermittent fasting could be an effective way for losing weight, especially belly fat, as it may slightly boost your metabolism while helping you consume fewer calories. The diet plan may also boost digestion and reduce bloating, as well as improve mental clarity. One of the best things about IF is that it may help those who tend to overeat with late-night snacking as fasting can reduce hunger, helping you stick to your diet plan.
         Refraining from eating food. The Bible describes three main forms of fasting: 1) The Normal Fast, involving the total abstinence of food. Luke 4:2 reveals that Jesus "did eat nothing." Afterwards "He was hungered." Jesus abstained from food but not from water. 2) In Acts 9:9 we read of an Absolute Fast where for three days He "neither did eat nor drink." The abstinence from both food and water seems to have lasted no more than three days (Ezra 10:6; Esther 4:16). 3) The Partial Fast-in Daniel 10:3 the emphasis is upon the restriction of diet rather than complete abstinence. The context implies that there were physical benefits resulting from this partial fast. However, this verse indicates that there was a revelation given to Daniel as a result of this time of fasting.
Fasting is not a way to be forgiven of your sins, but rather a way to grow closer to God after he has already forgiven your sins. For your sins to be forgiven, cry out to God and ask him for forgiveness. Jesus (God) took the punishment for your sins - past present and future. Ask God to forgive you because of Jesus' sacrifice on the cross and realize you cannot save yourself by fasting or any other way. Only God can save you. Salvation is mercy. It is a free, undeserved gift of grace and love. Meditate on that and on the Bible. Read the book of John.
You can still get great benefits while sneaking in a cup of coffee however if you want optimal results nothing should enter your stomach other than water while fasting. Not even meds. One of the reasons that the intermittent fasting is so effective is that the enzymes in your gut are allowed to rest. Your 8 hour window should start as soon as anything other than water is ingested which includes coffee. Again, that is the strict answer but you can certainly still get good benefits even if you have your coffee during your fast

It’s a good idea to weigh yourself before starting (and then again at the same time each week), and also to take chest, waist and hip measurements. The rate that you’ll lose depends on your age, levels of activity and your own body – so don’t be disheartened if you’re losing a pound a week while others are losing five or more. Typically weight loss will be faster at the beginning of the diet, and for those with a lot of weight to lose to reach a healthy weight (see this calculator to find out what a healthy weight - or BMI - is for someone of your height and weight).
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.
Methods of fasting also vary widely and cover a broad spectrum. If followed strictly, the person fasting does not partake any food or water from the previous day's sunset until 48 minutes after the following day's sunrise. Fasting can also mean limiting oneself to one meal during the day, abstaining from eating certain food types or eating only certain food types. In any case, the fasting person is not supposed to eat or even touch any animal products (i.e., meat, eggs) except dairy products. Amongst Hindus during fasting, starchy items such as Potatoes, Sago and Sweet potatoes are allowed. The other allowed food items include milk products, peanuts and fruits. It should be noted that peanuts and the starchy items mentioned above originate outside India.
Where diets complicate life, fasting simplifies. Where diets are expensive, intermittent fasting is free. Where diets can take time, fasting saves time. Where diets are limited, fasting is available anywhere. Where diets have variable efficacy, fasting has unquestioned efficacy. There is no more powerful method for lowering insulin and decreasing body weight.
Autophagy is spring cleaning for your cells. It’s Latin for “self-eating,” which is spot-on: when autophagy turns on, your cells sift through their internal parts, get rid of anything that’s damaged or old, and install shiny new versions.[8] Autophagy is like a tune-up for your car: afterward everything runs more smoothly. It reduces inflammation and even boosts longevity. Intermittent fasting triggers, to quote researchers, “profound” autophagy, especially in your brain.[9]
Fasting also helps us learn the lessons of the Day of Atonement : forgiveness, reconciliation to God and the need to resist Satan and pray for the time of his removal (Revelation 20:1-3 Revelation 20:1-3 1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. 2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years, 3 And cast him into the bottomless pit, and shut him up, and set a seal on him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
It can level up your brain, including positively counteracting conditions like Parkinson’s, Alzheimer’s, and dementia. As explained here in this TEDx talk by Mark Mattson, Professor at Johns Hopkins University and Chief of the Laboratory of Neurosciences at the National Institute on Aging fasting is grounded in serious research and more studies are coming out showing the benefits:
Plea through fasting. While keeping mind that fasting isn’t a manipulative tool to add to your prayer requests, you can still fast to give yourself wholly to God when you’re pleading for something or someone. Fast when you find a particular condition intolerable, and you can’t be satisfied until you spend time with God expressing your concerns about it.

God has reminded me the importance of preparation. I am not much for planning or preparing food in advance. However, since beginning the fast, the Lord has shown me that if I don't plan and prepare my food I will trip, fall or fail. There are so many temptation in an office setting. But, I was reminded that it is the same in the spirit. If I don't prepare by seeking him in prayer and worship daily, I will also trip, fall or fail.


Thursday fasting is common among the Hindus of northern India. On Thursdays, devotees listen to a story before opening their fast. On the Thursday fasters also worship Vrihaspati Mahadeva. They wear yellow clothes, and meals with yellow colour are preferred. Women worship the banana tree and water it. Food items are made with yellow-coloured ghee. Thursday is also dedicated to Guru and many Hindus who follow a guru will fast on this day.
The boss expects this to be done this afternoon, so you'd better work fast. He ran as fast as he could. This is fast becoming a national problem. You need to act fast to take advantage of this offer. I don't know what caused the accident. It all happened so fast. She's a woman who can think fast in a crisis. He's going to have to talk fast to get himself out of this mess. The window was stuck fast. She held fast to her belief in justice. We must stand fast and not surrender!
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.
In order for a fast for God to be effective, you must also pray. Praying and fasting to God is a powerful weapon against adversity. Joel 1:14 says, "Declare a holy fast; call a sacred assembly. Summon the elders and all who live in the land to the house of the Lord your God, and cry out to the Lord." A fast for God puts your trust in Him as the only one who can help you. During your fast for God, remember that He is faithful and true, willing and able to help you in any way He can.
For members of The Church of Jesus Christ of Latter-day Saints, fasting is total abstinence from food and drink accompanied by prayer. Members are encouraged to fast on the first Sunday of each month, designated as Fast Sunday. During Fast Sunday, members fast for two consecutive meals (24 hours); this is usually Sunday breakfast and lunch, thus the fasting occurs between the evening meal on Saturday and the evening meal on Sunday. The money saved by not having to purchase and prepare meals is donated to the church as a fast offering, which is then used to help people in need.[79] Members are encouraged to donate more than just the minimal amount, and be as generous as possible. The late LDS President Gordon B. Hinckley asked: "Think ... of what would happen if the principles of fast day and the fast offering were observed throughout the world. The hungry would be fed, the naked clothed, the homeless sheltered. … A new measure of concern and unselfishness would grow in the hearts of people everywhere."[80] Fasting and the associated donations for use in assisting those in need, are an important principle as evidenced by Church leaders addresses on the subject during General Conferences of the Church, e.g. The blessing of a proper fast in 2004, Is Not This the Fast That I Have Chosen? in 2015
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 (Matthew 6:16-17). Instead we should not “appear to men to be fasting, but to your Father who is in the secret place” (verse 18). Isaiah also contrasts selfish fasting with godly fasting marked by care and concern for others (Isaiah 58:3-10).
Carbs are only problematic when eaten excessively, beyond what your body requires. As long as you are eating low calories then carb intake will make very little difference in respect to fat loss. In other words, two diets of equal calories with varying levels of carb intake will result in the same level of fat loss. If you are still unsure then you can read this brilliant article by Lyle McDonald, Low Carbohydrate Diets Have No Metabolic Advantage. In addition, carbs in the main meal serve very important functions such as increasing leptin (improved satiety and metabolic rate), refilling depleted muscle glycogen stores and triggering the release of serotonin which will improve your quality of sleep and make you feel good.
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.
Wicked kings, destined for destruction, received mercy from humbling themselves and fasting (1 Kings 21:29). The entire city of Nineveh, including animals, fasted upon hearing the pronouncement of judgment from the prophet Jonah -- and God spared them (Jonah 3:10). Jesus received divine preparation for His earthly ministry while fasting and enduring temptation. Moses waited upon God forty days and received the divine revelation of God’s commandments.
Fat loss. Keto and intermittent fasting are a one-two punch for losing weight. Fasting and keto both spontaneously increase fat loss, even when people don’t intentionally restrict their calories.[18][19] When you pair intermittent fasting and keto together, you become a fat-burning machine. The weight comes off quickly, and because keto also suppresses ghrelin, you don’t get nearly as much of the hunger and feelings of deprivation that usually accompany weight loss.
Prayer and fasting is defined as voluntarily going without food in order to focus on prayer and fellowship with God. Prayer and fasting often go hand in hand, but this is not always the case. You can pray without fasting, and fast without prayer. It is when these two activities are combined and dedicated to God's glory that they reach their full effectiveness. Having a dedicated time of prayer and fasting is not a way of manipulating God into doing what you desire. Rather, it is simply forcing yourself to focus and rely on God for the strength, provision, and wisdom you need.
Prolonged very low calorie diets can cause physiological changes that may cause the body to adapt to the calorie restriction and therefore prevent further weight loss. [2] Intermittent fasting attempts to address this problem by cycling between a low calorie level for a brief time followed by normal eating, which may prevent these adaptations. However, research does not consistently show that intermittent fasting is superior to continuous low calorie diets for weight loss efficiency.

If you, Rahula, are desirous of doing a deed with the body, you should reflect on the deed with the body, thus: "That deed which I am desirous of doing with the body is a deed of the body that might conduce to the harm of self and that might conduce to the harm of others and that might conduce to the harm of both; this deed of body is unskilled (akusala), its yield is anguish, its result is anguish.
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.

Fasting is practiced by lay Buddhists during times of intensive meditation, such as during a retreat. During periods of fasting, followers completely stray away from eating animal products although, they do allow consumption of milk. Furthermore, they also avoid eating processed foods and the five pungent foods which are; garlic, welsh onion, garlic chives, asana, leeks.[26] The Middle Path refers to avoiding extremes of indulgence on the one hand and self-mortification on the other. Prior to attaining Buddhahood, prince Siddhartha practiced a short regime of strict austerity and following years of serenity meditation under two teachers which he consumed very little food. These austerities with five other ascetics did not lead to progress in meditation, liberation (moksha), or the ultimate goal of nirvana. Henceforth, prince Siddhartha practiced moderation in eating which he later advocated for his disciples. However, on Uposatha days (roughly once a week) lay Buddhists are instructed to observe the eight precepts[27] which includes refraining from eating after noon until the following morning.[27] The eight precepts closely resemble the ten vinaya precepts for novice monks and nuns. The novice precepts are the same with an added prohibition against handling money.[28]
