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”.

God uses fasting as a teaching tool on one of the annual holy days He commands us to keep. In Leviticus 23:27 God says “afflict your souls” on the Day of Atonement. The New Unger’s Bible Dictionary points out that afflicting your souls is a reference to fasting. So on this particular holy day God commands that His people forgo both food and water for 24 hours as a means of humbling themselves before Him, seeking Him and His will and guidance in life.
On the other five days of the week, there's no calorie cap, and no food is off-limits. This freedom isn't permission to binge and make up for your two fast days, but it does mean you shouldn't feel guilty about eating a slice of cake. U.S. News experts evaluate the Fast Diet poorly in all rankings, mostly due to its tough-to-follow nature and health risks in some populations.

Whole-day fasting involves regular one-day fasts. The strictest form would be alternate day fasting (ADF). This involves a 24-hour fast followed by a 24-hour non-fasting period. The alternate day modified fasting (ADMF) and 5:2 diets—the latter defined as five days per week not fasting and two days per week either total fasting or modified fasting—both allow the consumption of approximately 500–600 calories on fasting days.[1][3]
How It Works: This one’s easy: Eat very little one day, and eat like normal the next. On the low-calorie days, that means one fifth of your normal calorie intake. Using 2,000 or 2,500 calories (for women and men, respectively) as a guide, “fasting” (or “down”) day should be 400 to 500 calories. Followers can use this tool to figure out how many calories to consume on “low-calorie” days.
But it wasn’t until the 1940s that the first experiments began as an outgrowth of CR studies. Researchers started withholding food from lab animals on alternate days, says Michelle Harvie, a research dietitian in Manchester, England. And in 1946, The Journal of Nutrition published the first study on fasting, showing that rats deprived of food every third day lived longer and were less likely to develop tumors than control animals. Later work showed that fasting spurs metabolic changes similar to those of CR.
An informative description of the proclamation of a fast is in Jeremiah 36:9. There the people of Judah convened, apparently for the purpose of national repentance. This at least is what Jeremiah instructed Baruch to encourage them to do (vv. 7-8). Moreover, Jeremiah refers to the anticipated event as a "day of fasting" (v. 6), suggesting a common practice known to him and the people generally. In fact, Isaiah had spoken of such convocations a century earlier ( 58:3-6 ), gatherings on special days for special purposes. Regardless of Isaiah's feelings about the abuse of fasting, it is obvious that he recognized it as a legitimate form of worship and that he found no fault with it being carried out on specially called occasions.

When you eat a meal, your body spends a few hours processing that food, burning what it can from what you just consumed.  Because it has all of this readily-available, easy to burn energy (thanks to the food you ate), your body will choose to use that as energy rather than the fat you have stored.  This is especially true if you just consumed carbohydrates/sugar, as your body prefers to burn sugar as energy before any other source.


You’re consuming less food and thus spending less money. Rather than overeating to put on 1 pound of muscle and 4 pounds of fat in a week or two, you’re aiming to eat exactly enough to put on 1 pound of muscle without adding much fat on top of it.  Yeah, it’s a delicate balance, but there’s far less swing involved. You are just slowly, steadily, and consistently building muscle and strength over many months.
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]
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).
On my fasting days, I would wake up, have coffee, and start my day without any food. This would continue until about 5:30 p.m., when I would prepare a dinner that didn’t vary from my regular dinner in terms of either what or how much I ate. So, my fasting dinner would be something normal for me, like stir-fry, pasta, soup, sandwich, sushi, etc. This dinner looked like any other and occurred at the usual time. This made it simpler — I was just resuming eating with no special fanfare.
Jesus equates supplication and fasting when he teaches that the removal of mountains comes about only by prayer and fasting ( Matt 17:21 ). The godly prophetess Anna looked for the redemption of Israel with supplicatory prayer and fasting ( Luke 2:37 ). Before Paul and Barnabas appointed elders for the various churches, they committed them to the Lord with prayer and fasting ( Acts 14:23 ). In all these instances there is the clear implication that fasting is an effective adjunct to petition.
I have found that the 4:3 style fasts have worked well for my friends and me based on our work/life schedule and our personal health goals. I like that full day fasts feel like an on/off switch — I don’t think about eating on fast days and on eat days if I happen to overeat, I don’t feel guilty about it (since I’m eating at a deficit during the week). I find it more manageable to cut calories over a week (using the 4:3 style of IF) instead of every day (trying to eating less daily).

Thanks for bringing this to our attention, I believe Muslims are urged to fast entirely, whereas the fasting diet plan or 5:2 diet allows people to eat and drink a small amount of food throughout the day. Having said this if this is something you have been doing your entire life perhaps you have some great tips you can share that makes fasting easier?

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.
Muslims believe that fasting is more than abstaining from food and drink. Fasting also includes abstaining from any falsehood in speech and action, abstaining from any ignorant and indecent speech, and from arguing, fighting, and having lustful thoughts. Therefore, fasting strengthens control of impulses and helps develop good behavior. During the sacred month of Ramadan, believers strive to purify body and soul and increase their taqwa (good deeds and God-consciousness). This purification of body and soul harmonizes the inner and outer spheres of an individual. Muslims aim to improve their body by reducing food intake and maintaining a healthier lifestyle. Overindulgence in food is discouraged and eating only enough to silence the pain of hunger is encouraged. Muslims believe they should be active, tending to all their commitments and never falling short of any duty. On a moral level, believers strive to attain the most virtuous characteristics and apply them to their daily situations. They try to show compassion, generosity and mercy to others, exercise patience, and control their anger. In essence, Muslims are trying to improve what they believe to be good moral character and habits.

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.
Medical supervision is recommended for any fast over three days. Most alternative medicine practitioners, such as homeopaths, naturopathic doctors, and ayurvedic doctors, can supervise and monitor patients during fasts. Those performing extended fasts and those with health conditions may require blood, urine, and other tests during fasting. There are many alternative health clinics that perform medically supervised fasts as well. Some conventional medical doctors may also supervise patients during fasts. Costs and insurance coverage vary, depending on the doctor, clinic, and requirements of the patient.
The most common approach to eating less than you burn is to “watch what you eat” or to eat at a low-grade calorie deficit all the time. At every meal, eat about 10 to 20 percent fewer calories than you need in order to maintain that deficit, which requires your body to dip into its reserves and burn excess fat. This can be mentally difficult, because you always have to be restricting calories.
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.
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.
Saint Augustine's Prayer Book defines "Fasting, usually meaning not more than a light breakfast, one full meal, and one half meal, on the forty days of Lent."[45] Abstinence, according to Saint Augustine's Prayer Book, "means to refrain from some particular type of food or drink. One traditional expression of abstinence is to avoid meat on Fridays in Lent or through the entire year, except in the seasons of Christmas and Easter. It is common to undertake some particular act of abstinence during the entire season of Lent. This self-discipline may be helpful at other times, as an act of solidarity with those who are in need or as a bodily expression of prayer."[46]
