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.
Studies on every-other-day fasting show mixed results. One published in 2010 in the Nutrition Journal suggested that the technique was effective among a group of obese patients. A group of 16 participants ate only one meal – lunch – every other day, and they were limited to about 500 calories. That's the same amount of calories women consume on the Fast Diet's fasting days. On the days when the study participants were not fasting, they were not constrained to any rules. Over the course of eight weeks, the participants lost an average of 12 3/10 pounds.

What is ghrelin? It is actually also known as the hunger hormone, because it is responsible for telling your body that it is hungry. Dieting and really restrictive eating can actually increase ghrelin production, which will leave you feeling hungrier. But when you fast, though you might struggle in the first few days, you’re actually normalizing ghrelin levels.


”A lot of organs start shrinking [during a periodic fast],” Longo explained. “A lot of cells start dying and we have evidence a lot of the cells killed by this process are the bad cells. Then the stem cells get turned on, and we see the body starts regenerating itself.” What’s more, he added, certain inflammatory markers and biomarkers for cancer seem to be lowered when animals and humans fast.

3 days in a 16:8 ration – my body loves it. I don’t feel famished and look forward to my 8 hrs of eating window. I keep calories in check with a healthy balanced diet. My exercise begins after my last hour of fasting, I eat a few fruits (mango and raspberries) and an avocado (topped with a homemade crushed walnut dressing) and I’m good to lift weights and run. My body feels light and healthy. Amazing solution to any fitness junky.
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.)
The second one is more subtle: The body shifts into fat-burning mode when it doesn’t get food for an extended period of time. That’s because the body’s first source of fuel is glycogen, and it only turns to burning body fat once that quickly available energy source is depleted. So when you fast for long enough, you drive down stores of glycogen and start burning fat tissue. “In people, we see a change in fasting glucose — it’s lower — and abdominal fat is affected without much of an effect on the muscles,” Longo explained.

As long as you’re aware that it isn’t nutritional magic, Sasson isn’t against intermittent fasting altogether. “I’ve worked with patients who need positive reinforcement to see that their weight went down to feel better, and they feel in control for the first time,” she says. “That self-efficacy, that feeling that they could do it—for some, that might be important.”
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 Bible gives examples of God’s people occasionally combining fasting with their prayers so as to stir up their zeal and renew their dedication and commitment to Him. King David wrote that he “humbled [him]self with fasting” (Psalms 35:13 Psalms 35:13But as for me, when they were sick, my clothing was sackcloth: I humbled my soul with fasting; and my prayer returned into my own bosom.

From a Christian perspective, there are many options. One may go on only fruits and vegetables for a day or more. One may do a complete fast, involving only water and no food for a specific period of time. One may skip breakfast intentionally to pray and focus on God, and then eat lunch. Caloric restriction, especially when one is not doing complete food fast, offers the opportunity to live what some have described as a “fasted life.” The key is to choose a plan that works for you at that time and to start small. In all cases, the important thing is to intentionally focus on God in prayer.
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).
Hi I'm happy that I was able to accomplish this 1st week...but I would honestly say that I feel tired and want to sleep.....I prayed and try to stay connected with my heavenly father, but honestly it is really hard when you are fasting alone and you still need to continue with a regular schedule...such as cooking for your children....go to work....and attend different activities that are required. Please pray for me so I can continue this fast but on another level, I need strength, motivation and continue with the main goal that is a closer and meaningful relationship with Him. :(
In the religions of some tribes of Native Americans, fasting was practiced before and during a vision quest. Among the Evenk of Siberia, shamans (religious personages thought to have the power to heal and to communicate psychically) often received their initial visions not with a quest but rather after an unexplained illness. After the initial vision, however, they fasted and trained themselves to see further visions and to control spirits. Historically, priestly societies among the Pueblo Indians of the American Southwest fasted during retreats before major ceremonies connected with seasonal changes.
This proved to be the most important forty days of my life. As I waited upon the Lord, the Holy Spirit gave me the assurance that America and much of the world will, before the end of the year 2000, experience a great spiritual awakening. This divine visit from heaven will kindle the greatest spiritual harvest in the history of the Church. But before God comes in revival power, the Holy Spirit will call millions of God's people to repent, fast, and pray in the spirit of 2 Chronicles 7:14:
Repent through fasting. Empathize with God’s grief over your sins by fasting. Engage your entire person in repentance by using your body to turn away from self-indulgence and toward God. At church, schedule some times to fast with others for group repentance, just as you all sometimes gather to feast together in celebration (at church parties, potluck dinners, etc.). Express your personal repentance through fasting at times like during Lent and Holy Week, when God seems absent from your life, and when you realize your own complicity in society’s moral wrongs.

In the religions of ancient peoples and civilizations, fasting was a practice to prepare persons, especially priests and priestesses, to approach the deities. In the Hellenistic mystery religions (e.g., the healing cult of the god Asclepius), the gods were thought to reveal their divine teachings in dreams and visions only after a fast that required the total dedication of the devotees. Among the pre-Columbian peoples of Peru, fasting often was one of the requirements for penance after an individual had confessed sins before a priest. In many cultures the practice was considered a means to assuage an angered deity or to aid in resurrecting a deity who was believed to have died (e.g., a god of vegetation).
DU: The biggest benefit of fasting is disciplining us to focus on God long enough to be changed by Him. I have seen brothers and sisters who, after spending much time in God’s presence through prayer and fasting, have been significantly empowered to carry out God’s call on their lives. From a medical perspective, there are a significant number of credible studies showing that fasting substantially reduces the risk for type 2 diabetes, heart disease, and cancer. I reviewed scientific literature on the health benefits of fasting going back up to 70 years, and what I found is that fasting improves our health span if it is done consistently and intermittently as a lifestyle.

Forms of intermittent fasting exist in religious practices in various groups across the world.[8] Religious fasting regimens include, but are not limited to, Vrata in Hinduism, Ramadan fasting (Islam), Yom Kippur fasting (Judaism), Orthodox Christian fasting, Fast Sunday (The Church of Jesus Christ of Latter-day Saints), and Buddhist fasting.[8] Certain religious fasting practices, like Buddhist fasting, only require abstinence from certain foods, while others, like the Jewish fast on Yom Kippur, last for a short period of time and would cause negligible effects on the body.[8] Islam is the only major religion that engages in a fasting practice reflective of intermittent fasting in terms of both food consumption and diet consistency.[8] The duration of the Ramadan fast is between 28 and 30 days, depending on the year, and consists of not eating or drinking from sunrise until sunset.[8] During the holiday, Muslims eat twice per day: once in the morning before dawn and once in the evening after dusk.[8] A meta-analysis on the health of Muslims during Ramadan shows significant weight loss during the fasting period of up to 1.51 kilograms (3.3 lb), but this weight was regained within about two weeks of Ramadan ending.[9] The analysis concluded that "Ramadan provides an opportunity to lose weight, but structured and consistent lifestyle modifications are necessary to achieve lasting weight loss."[9] Negative effects of Ramadan fasting include increased risk of hypoglycemia in diabetics as well as inadequate levels of certain nutrients.[8]
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]
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.
This type of fasting is also known as cyclic fasting. Intermittent fasting is a catch-all phrase for eating (and not eating) intermittently. In fact, almost all of the fasting methods below are types of intermittent fasting! Typical intermittent fast times range from 14 to 18 hours. The longest period any one of these plans would require you to abstain from solid food would be about 32–36 hours.
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.
Some of this newly created fat is stored in the liver, but most of it is exported to other fat deposits in the body. While this is a more complicated process, there is no limit to the amount of fat that can be created. So, two complementary food energy storage systems exist in our bodies. One is easily accessible but with limited storage space (glycogen), and the other is more difficult to access but has unlimited storage space (body fat).
A systematic review of 40 studies found that intermittent fasting was effective for weight loss, with a typical loss of 7-11 pounds over 10 weeks. [2] There was much variability in the studies, ranging in size from 4 to 334 subjects, and followed from 2 to 104 weeks. It is important to note that different study designs and methods of intermittent fasting were used, and participant characteristics differed (lean vs. obese).  Half of the studies were controlled trials comparing the fasting group to a comparison group and/or a control group (either continuous calorie restriction or usual lifestyle), with the other half examining an intermittent fasting group alone. A brief summary of their findings:
Listen to your body during workouts. If you get light headed, make sure you are consuming enough water. If you notice a significant drop in performance, make sure you are eating enough calories (especially fats and protein) during your feasting window. And if you feel severely “off,” pause your workout. Give yourself permission to EASE into intermittent fasting and fasted workouts. This is especially true if you are an endurance athlete.
Bhagiratha says, The vow of fast was known to Indra. He kept it a secret but USANAS first made it known to the universe. Bhagiratha says, "In my opinion, there is no penance higher than fast." Bhagiratha did many sacrifices and gave gifts and says "the present that flowed from me were as copious as the stream of the Ganga herself.(but ..) it is not through the merits of these acts that I have attained this region." Bhagiratha observed the vow of fasting and reached "the region of Brahman"
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).
In section 106, of the same book, Yudhishthira says, "the disposition (of observing fasts) is seen in all orders of men including the very Mlechchhas..... What is the fruit that is earned in this world by the man that observes fasts?" Bheeshma replies that he had asked Angiras "the very same question that thou has asked me today." The illustrious Angiras says Brahmans and kshatriya should fast for three nights at a stretch is the maximum. A person who fasts on the eight and fourteenth day of the dark fortnight "becomes freed from maladies of all kinds and possessed of great energy."
The Fast Diet is only an eating pattern, but that doesn't mean you shouldn't exercise. In fact, being physically active lowers your risk of heart disease and diabetes, helps keep weight off and increases your energy level. Most experts suggest getting at least 30 minutes of moderate-intensity exercise – like brisk walking – most or all days of the week.
On its web site, the Academy of Nutrition and Dietetics says that although there is evidence that intermittent fasting diets may help prevent chronic disease, more research is needed. It doesn't recommend the diet because "it is not a realistic long-term solution.” The academy also notes that "any variation of fasting may make a person irritable, cause daytime sleepiness/sleeplessness at night, and can even lead to dehydration."
If you haven't met someone who's into intermittent fasting (IF), that's likely to change pretty soon. As one of the biggest diet trends in 2018, people who swear by IF say it has helped them lose weight and accelerate fat loss, gain muscle, and feel healthier overall. Although the idea behind this controversial eating plan isn't exactly a new one—it was used in the early 1900s to treat disorders such as diabetes and epilepsy—it's been gaining traction with dieters today with new intermittent fasting methods such as The Fast Diet (aka the 5:2 program) and the 16:8 method. But what is intermittent fasting exactly—and how can you use it to help you lose weight?
Thanks for your insight, there are millions of people throughout the world who fast for religious reasons, it is a part of honoring their faith. If someone is fasting to lose weight, improve their health, improve immunity and decrease their insulin sensitivity (or any of the other many health benefits associated with fasting) then yes I agree we promote and encourage you to drink water throughout your fasting days. Why? Drinking water helps keep the body hydrated which is important since we are made up of more than 70% water, it helps you from being dehydrated, which when people feel dehydrated they often feel hungry and want to eat and lastly water helps flush toxins and waste materials from the body. When fasting you will be breaking down waste and other by products so it is important to flush them out of your body; this will also aid your digestion and improve your overall well being.
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.
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.
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?
Yes, it's a good idea for believers to fast from time to time. Fasting is not required in Scripture, but it's highly recommended. The primary Biblical reason to fast is to develop a closer walk with God. By taking our eyes off the things of this world, we can focus better on Christ. "When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show men they are fasting. I tell you the truth, they have received their reward in full. But when you fast, put oil on your head and wash your face, so that it will not be obvious to men that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you" (Matthew 6:16-18).
Because we don't enter the fasted state until 12 hours after our last meal, it's rare that our bodies are in this fat burning state. This is one of the reasons why many people who start intermittent fasting will lose fat without changing what they eat, how much they eat, or how often they exercise. Fasting puts your body in a fat burning state that you rarely make it to during a normal eating schedule.
To begin, you may wish to try spending about 1 week, or so, eating smaller meals and abstaining from sugary foods and caffeine to prepare yourself for total fasting. The 2 days before you begin your actual fast, you might eat only fruits and vegetables, while drinking only water. This will prepare your appetite (physically) and your mind for going without your favorite foods.
American King James Version×), though other national fast days are mentioned in the Bible. Also, personal fasts are clearly expected of Christ’s disciples (Matthew 9:14-15 Matthew 9:14-15 14 Then came to him the disciples of John, saying, Why do we and the Pharisees fast oft, but your disciples fast not? 15 And Jesus said to them, Can the children of the bridal chamber mourn, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and then shall they fast.
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.
BUT I stopped losing weight since last 2 weeks, so I stopped doing IF for last a week and my tummy looks same as before and I gained 3/4 lbs back. I am trying to do IF again but I cannot, because I’m getting constantly hungry. I used to start Fasting at 7pm & & break at 11/12pm next day. But My new job schedule is from 5:30, so its hard for me to wait until noon. I tried a different schedule from 4pm to 8am but I get hungry at night, so it didn’t help me either. Please help me.
Because it simplifies your day. Rather than having to prepare, pack, eat, and time your meals every 2-3 hours, you simply skip a meal or two and only worry about eating food in your eating window. It’s one less decision you have to make every day. It could allow you to enjoy bigger portioned meals (thus making your tastebuds and stomach satiated) and STILL eat fewer calories on average.
Cons: Even though it’s nice to eat a few snacks rather than go without any food for 20-plus hours, the guidelines for what you need to eat (and when) can be hard to follow long-term. The strict schedule and meal plan may also interfere with social gatherings. Additionally, eating one main meal at night — while following strict guidelines of what to eat, and in what order — can be tough. It’s especially hard for those who prefer not to eat large meals late in the day.
A healthy person who is not perspiring much can go without food and water for about three days before the body begins to be stressed. And a healthy person can go without food for several days if he is drinking water. Thus, the amazingly long 40-day fasts by Moses, Elijah and Jesus Christ (Deuteronomy 9:9 Deuteronomy 9:9When I was gone up into the mount to receive the tables of stone, even the tables of the covenant which the LORD made with you, then I stayed in the mount forty days and forty nights, I neither did eat bread nor drink water:
Intermittent fasting, unlike many other diets, is famously flexible in that you choose the days and hours during which you think it’s best to fast. The two most common methods are the 16:8 strategy—where you eat whatever you want (within reason) for eight hours a day and then fast for the other 16—and the 5:2 method, where you eat normally five days a week and then keep your food intake to roughly 500-600 calories for the other two days. It’s kind of a simplified-calories math problem that’s supposed to prevent the yo-yo effect of weight loss and weight gain.
If you’re eating processed foods and potato chips, it’s unlikely you’ll reap the benefits of fasting. If that’s you, I encourage you to examine your diet before trying a fast. But if you practice fasting and stick to a mostly whole food diet, rich in fruits, veggies, lean proteins, healthy fats and raw dairy, you will see changes — and those occasional splurges on chocolate or cheese won’t have as big of an impact as they might if you were on a calorie-restrictive diet.
Expect funny looks if you spend a lot of mornings with breakfast eaters.  A few weeks back I had a number of friends staying with me, and they were all completely dumbfounded when I told them I didn’t eat breakfast anymore. I tried to explain it to them but received a bunch of blank stares. Breakfast has become so enGRAINed (zing!) in our culture that NOT eating it sounds crazy.  You will get weird looks from those around you…embrace it. I still go to brunch or sit with friends, I just drink black coffee and enjoy conversation.
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:
This is a type of spiritual fasting. Based off of Daniel’s experiences in the Bible’s Book of Daniel, the Daniel Fast is a partial fast where vegetables, fruits and other healthy whole foods are featured prominently, but meat, dairy, grains (unless they’re sprouted ancient grains) and drinks like coffee, alcohol and juice are avoided. Most people follow this fast for 21 days in order to experience a spiritual breakthrough, have more time to reflect on their relationship with God or just to feel closer to what Daniel would have experienced in his time.
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.
If the better part of wisdom for you, in your health condition, is not to go without food, consider fasting from television, computer, social media, or some other regular enjoyment that would bend your heart toward greater enjoyment of Jesus. Paul even talks about married couples fasting from sex “for a limited time, that you may devote yourselves to prayer” (1 Corinthians 7:5).

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.
