On this plan you'll eat clean five days of the week but will not eat anything for two nonconsecutive days of the week. For example, you can fast on Monday and Thursday but eat clean meals on the other days. Food on these five days will look just like the rest of the fasting plans—healthy fats, clean meat sources, vegetables, and some fruit. Keep in mind that this plan is not for beginners, and you should always talk to your doctor before starting any fasting regimen, especially if you are on medication or have a medical condition.
Alternative medicine A period of voluntary abstinence from foods and/or drinks; fasting is integral to many religions, as it is believed to purify the mind and spirit; fasting rests the GI tract, and may rid the body of toxins and undigested metabolites; fasting leads to a loss of water, Na+, and K+, resulting in postural hypotension, and decreased blood sugar resulting in depression, fatigue, decreased libido, and malaise, increased nitrogen in the circulation due to protein breakdown, and may result in premature childbirth—Yom Kippur effect
Thirty-six young healthy male volunteers were placed on a 24-week calorie-restricted diet of about 1,600 calories per day. They also had to walk for about 45 minutes a day. But instead of resulting in continuous weight loss, at 24 weeks their weight had stabilized, and no more weight loss could be elicited even when he reduced calorie intake down to 1,000 or less per day.
This type of dietary pattern would be difficult for someone who eats every few hours (e.g., snacks between meals, grazes). It would also not be appropriate for those with conditions that require food at regular intervals due to metabolic changes caused by their medications, such as with diabetes. Prolonged periods of food deprivation or semi-starvation places one at risk for overeating when food is reintroduced, and may foster unhealthy behaviors such as an increased fixation on food. [7,8]
Thank you very much for the great article. As a Muslim, we are encouraged to fast two days a week (Monday and Thursday)! It is not a must, just preferred. We fast from sunrise to sunset. No food or drink is allowed during this period (no water). As you mentioned a true fast can be a mental and physical cleansing time. From a personal experience, fasting is really great. I strongly believe it has many benefits on the mind and body as well if done correctly.
Longo warned that any fasting diet should start with a visit to the doctor. Fasting studies have not been done in children, very elderly people, or people who are underweight — so it’s possible fasting could be harmful in these cases. “If you’re a diabetic and taking insulin or any other drugs, or if you have metabolic disorders, you should not fast,” he added, noting that fasts done poorly can also increase the risk of gallstones.
In practice, however, I would be concerned with eating enough. Based on my experience, teaching yourself to consistently eat more is one of the harder parts of intermittent fasting. You might be able to feast for a meal, but learning to do so every day of the week takes a little bit of planning, a lot of cooking, and consistent eating. The end result is that most people who try intermittent fasting end up losing some weight because the size of their meals remains similar even though a few meals are being cut out each week.
Studies show that intermittent fasting accelerates weight loss. In a 2015 review pooling 40 different studies, participants shed on average 10 pounds in a 10-week period.[1] Another study found that obese adults following an “alternate day” intermittent fasting schedule (eating 25 percent of their daily calories on one day, and eating normally the following day) lost up to 13 pounds over 8 weeks.[2]
The purpose in fasting for God is not about giving up food; it is about removing the obstacles that get in the way of fully focusing on Him. Human beings are conditioned to eat, usually 3 meals a day and snacks. We are so focused on what we are going to eat next, we leave very little room in our minds for thinking about God. Removing the food will free up your mind so you can meditate on God.
In addition to our attitudes towards God and our stance before man, our motives must also be correct. We should fast in order to further the building up of God’s kingdom by seeking to minister to others. The prophet Isaiah received from the Lord the acceptable motives for our fasts: “Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke? Is it not to share your food with the hungry and to provide the poor wanderer with shelter -- when you see the naked, to clothe him, and not to turn away from your own flesh and blood?” (Isaiah 58:6-7).

Not only does fasting and prayer help us focus on God, but through that time, it brings us closer to Him and changes our hearts. Niles and Little write, "When we fast and pray, we are taking time away from a meal or an activity to devote our entire being to focus on God. We find we are more sensitive to the voice of God, more attuned to hearing what He has to reveal to us. Gently, God whispers in our mind what we were really thinking at the time of our sin, what our true intent was and we are shocked…momentarily. Then like a light turned on in a pitch black room, we see it. We did mean harm. We were manipulative. Even though our recognition makes us want to hide our face, our loving Savior lifts our chin to look into his forgiving eyes. As we repent, we no longer want to hide, but to praise and worship the very one who confronted our wrong."

Pros: While 24 hours may seem like a long time to go without food, the good news is that this program is flexible. You don’t have to go all-or-nothing at the beginning. Go as long as you can without food the first day and gradually increase fasting phase over time to help your body adjust. Pilon suggests starting the fast when you are busy, and on a day where you have no eating obligations (like a work lunch or happy hour).
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.
Those desiring to receive Holy Communion keep a total fast from all food and drink from midnight the night before (see Eucharistic discipline). The sole exception is the Communion offered at the Easter Sunday midnight liturgy, when all are expressly invited and encouraged to receive the Eucharist, regardless of whether they have kept the prescribed fast.
Fasting can take up a significant portion of the calendar year. The purpose of fasting is not to suffer, but according to Sacred Tradition to guard against gluttony and impure thoughts, deeds and words.[50] Fasting must always be accompanied by increased prayer and almsgiving (donating to a local charity, or directly to the poor, depending on circumstances). To engage in fasting without them is considered useless or even spiritually harmful.[47] To repent of one's sins and to reach out in love to others is part and parcel of true fasting.
Good Friday, which is towards the end of the Lenten season, is traditionally an important day of communal fasting for Methodists.[38] Rev. Jacqui King, the minister of Nu Faith Community United Methodist Church in Houston explained the philosophy of fasting during Lent as "I'm not skipping a meal because in place of that meal I'm actually dining with God".[62]

The second major day of fasting is Tisha B'Av, the day approximately 2500 years ago on which the Babylonians destroyed the first Holy Temple in Jerusalem, as well as on which the Romans destroyed the second Holy Temple in Jerusalem about 2000 years ago, and later after the Bar Kokhba revolt when the Jews were banished from Jerusalem, the day of Tisha B'Av was the one allowed exception. Tisha B'Av ends a three-week mourning period beginning with the fast of the 17th of Tammuz. This is also the day when observant Jews remember the many tragedies which have befallen the Jewish people, including the Holocaust.

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.”
All three types offer the same fat-burning benefits of intermittent fasting. The real differences are just in how long you’re fasting and what you’re allowed to eat during the fast, Varady says. On both whole-day fasting and alternate-day fasting, for example, you consume 500 calories per fast day to spark fat loss but maintain muscle. During time-restricted feeding, however, you’re consuming zero calories during your fast period (water and tea, for example, are allowed). In all types, you’re free to go hog-wild during the feeding window—though, obviously, all nutritionists would recommend you ditch the junk and stick to healthy fare.
Fasting can be used for nearly every chronic condition, including allergies, anxiety, arthritis, asthma, depression, diabetes, headaches, heart disease, high cholesterol, low blood sugar, digestive disorders, mental illness, and obesity. Fasting is an effective and safe weight loss method. It is frequently prescribed as a detoxification treatment for those with conditions that may be influenced by environmental factors, such as cancer and multiple chemical sensitivity. Fasting has been used successfully to help treat people who have been exposed to high levels of toxic materials due to accident or occupation. Fasting is thought to be beneficial as a preventative measure to increase overall health, vitality, and resistance to disease. Fasting is also used as a method of mental and spiritual rejuvenation.

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.


Isn’t it interesting that we in the Western world think going for 12 hours w/o water is harmful? Millions do this and it seems w/o much harm. As a person with an autoimmune, this has been really helpful in tracking down the food which really bothers me. The list of have-not is endless and really bums me out BUT at least I know what I can put in my mouth w/o too much harm. 1 out of 3 suffer from some kind of skin issue, most all being traced back to what you put in your mouth. If one doesn’t stop putting stuff in their mouths how would one EVER know?

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.
New Delhi: As more and more people are trying to lose weight, intermittent fasting (IF) continues to be one of the most popular fitness trends across the world. Studies have shown that IF can be a powerful weight loss tool that can effectively help you fight belly fat while also improving health in many ways. It is claimed that it can benefit your brain health, reduce your risk of certain conditions - such as diabetes, heart disease, cancer, - and may even help you live a longer life.
Along with obligatory prayer, it is one of the greatest obligations of a Bahá'í.[22] In the first half of the 20th century, Shoghi Effendi, explains: "It is essentially a period of meditation and prayer, of spiritual recuperation, during which the believer must strive to make the necessary readjustments in his inner life, and to refresh and reinvigorate the spiritual forces latent in his soul. Its significance and purpose are, therefore, fundamentally spiritual in character. Fasting is symbolic, and a reminder of abstinence from selfish and carnal desires."[23]
