In addition to these, there is the fast of repentance which a person keeps after committing sin, it being imposed as a penance by the priest for seven days, forty days or one year. There is also a fast which a bishop keeps at the time he is consecrated. Also there are fasts that are widely observed but which have not been included in the canon of the church and which are therefore considered strictly optional such as the "Tsige Tsom" or Spring Fast, also known as "Kweskwam Tsom" which marks the exile of the Holy Family in Egypt.
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."
“Cycles of fasting can reset and rejuvenate the human body,” said Valter Longo, director of the Longevity Institute at the University of Southern California. Periods with no food, he said, help the body eliminate and replace damaged cells with new ones through a process called autophagy (the study of which recently garnered a Nobel Prize). (Longo is a leading fasting researcher but he’s pretty dug in — with a book about fasting, and a company that sells fasting products. He says he donates all the proceeds from the company and the book to health charities.)
The Hebrew verb sum [Wx] is the only one used to describe fasting as a religious exercise. It (and its cognate noun som [/x]) conveys the explicit meaning "to abstain from food" and thus occurs regularly as a technical religious term. The Greek verb nesteuo [nhsteuvw] and its companion noun nesteia [nhsteiva] occur consistently in the Septuagint as translations of Hebrew sum [Wx] and som [/x] and as the usual terms for fasting in the New Testament.
In 2017, Longo was a co-author on the first human trial of whether fasting might reduce the risk factors for diseases like diabetes, cancer, and cardiovascular disease. The researchers randomized 100 people into one of two groups for three months: The first group ate anything they wanted, and the second fasted for five consecutive days each month. (By “fasted” here, I mean, they followed the fasting-mimicking diet.) After three months, the first group was crossed over into the fasting group, so the researchers could gather even more data on fasting.
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?

Longer fasts likewise can take the form of abstinence from food or some other sacrifice. Some good options for a non-food fast would be abstaining from watching TV from Monday to Friday, reading a biography of a great man or woman of God each week, or dedicating every evening for a week to praying with friends...A longer water-only fast might last from one to three days. If you are fasting from something other than food, your longer fast might last a week. Some use Lent as a time for a longer fast. 

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.
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.
Yes, you'll be hungry at times—but it's not necessarily overwhelming or constant. "Hunger doesn't seem to get worse as the day goes on, and some of our studies report increased fullness and satisfaction," says Kristin Hoddy, Ph.D., R.D.N., a dietitian in private practice who has researched fasting. "Some subjects remarked that they'd get distracted and 'forget' they were hungry."

Although I do not fast like you do (from sunrise to sunset) I do continue to fast not just to maintain my weight but to free the mind and body or the extra weight and burdens that it must carry. You see when your stomach is not full and your mind is not sluggish from trying to digest a heavy meal you start to have more energy think clearer, sleep better and feel better. When you can have this in your life for free why not take it. Some people spend thousands to have access to these feelings when we can experience a little bit of this each week.

Aside from these official days of fasting, Jews may take upon themselves personal or communal fasts, often to seek repentance in the face of tragedy or some impending calamity. For example, a fast is sometimes observed if a sefer torah is dropped. The length of the fast varies, and some Jews will reduce the length of the fast through tzedakah, or charitable acts. Mondays and Thursdays are considered especially auspicious days for fasting. Traditionally, one also fasted upon awakening from an unexpected bad dream although this tradition is rarely kept nowadays.
For those looking into getting into these fad diets. They all work, to an extent. The “best” diet is most certainly the one that you can most adhere to. That being said, so long as you are in a caloric deficit, you will lose weight! Face it, what is the point when you diet down and can not keep the weight off? You will most certainly rebound and end up right where you started. Consult with your doctor first and foremost for health and welfare issues and follow-up with a professional. Your health is of utmost importance. Take care everyone.
Although CR might be metabolic magic, it’s no magic bullet. Some mice bred to carry certain genes for lab research don’t benefit from it, and it actually shortens life in other genetically modified mice. The deprivation can weaken the immune system of very young and very old animals, making them susceptible to disease. And although cutting calories by 25 percent has been standard, it’s not clear if that’s best for animals and humans.

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.
Whether you are considering a 12-hour fast, a two-day fast, or a daily low calorie fast, you should talk to your doctor before beginning a new eating regimen. Certain medical conditions may get worse with sudden changes in diet and some medications are affected by changing the foods you eat. A doctor can help you weigh the possible benefits and consequences of a fast to see if it’s right for you.
On first fast days, people often expect to feel really hungry. But thought you will be aware of eating less, you’ll probably be surprised at how quickly any pangs pass, especially if you keep busy with work or other activities. On the first few fasts, some people report feeling the cold more, or experiencing headaches – both of these are common with all diets. Most people find it gets much easier after the first one of two fasts.
^ Bhikkhu, Thanissaro (5 June 2010). "Questions of Skill". Access to Insight. John T. Bullitt. Retrieved 7 June 2011. Each time you're about to act, ask yourself: "This action that I want to do: would it lead to self-harm, to the harm of others, or to both? Is it an unskillful action, with painful consequences, painful results?" If you foresee harm, don't follow through with it.

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.
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.
4) A sensitivity to God’s voice. The New Testament prophetess Anna is praised in the book of Luke for being a devoted servant to God and His temple. Because she regularly fasted and prayed, she was able to hear the voice of God speak clearly to her the day that Baby Jesus was brought into her temple to be dedicated. She knew He was the Christ and told everyone who would listen about His arrival. When we detox the spirit and become consumed with desire and praise for God, we become sensitive to His voice. Like Anna, when God speaks to us in the midst of chaos, we’ll still be able to pick out His voice and know what He wants us to do because we have trained our ear to hear Him through fasting, prayer, study and praise.
When I started intermittent fasting, I spent a lot of time thinking about how I wasn’t eating. I would think about how hungry I was, and then, when it came time to break my fast, I would eat more than a regular dinner, thinking I deserved it after having fasted all day. This is how people fail at intermittent fasting. It took me about two weeks to figure it out.

Fasting is an ancient practice sparking new interest in both pop and scientific culture. Entrepreneurs, venture capitalists and a variety of celebrities have extolled its virtues in helping them lose weight, while medical experts are intrigued by the possibility that it may enhance cognitive functioning and longevity and help treat and prevent some diseases.
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."

Another study, this one out of the University of Southern California, discovered that when 71 adults were placed on a five-day fast (eating between 750 and 1,100 calories a day) once every three months, they lost an average of 6 pounds, reduced inflammation levels and their waistlines and lost total body fat without sacrificing muscle mass. (2) If you want to lose weight and lose belly fat, fasting even irregularly could be the key.
The health benefits of fasting are extremely appealing, but I do want to stress that fasting isn’t always for everyone. People who suffer from hypoglycemia and diabetics should probably avoid fasting, up until blood glucose and insulin levels have been normalized. Pregnant and breastfeeding women should absolutely not fast, as it can have negative effects on the baby.

I’m 65 and I retired recently. I tried this for one week, and I must admit I particularly watched the clock all day long. I was very intergetic, and my depression subsided most of the time. At one week I weight myself, and thought why am I doing this if I’m not losing weight? So I went off and now I feel like I drag most of the day. I’m getting back on…enough said.
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.
In some specific periods of time (like Caturmasya or Ekadashi fasting) it is said that one who fasts on these days and properly doing spiritual practice on these days like associating with devotees -sangha, chanting holy names of Hari (Vishnu, Narayana, Rama, Krishna) and similar (shravanam, kirtanam vishno) may be delivered from sins.[citation needed]

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.)
Based on my experience, 24-hour fasts will get me into ketosis much faster than other methods like the fat fasting technique. To make the fast easier, I generally start my fast about 3–4 hrs before I go to bed the night before your full day fast. That means if I am going to fast all day Sunday, I start the fast on Saturday night right after my final meal. That way when I wake up, I am 11–12 hrs into my fast.

The Armenian Apostolic Church (with the exception of the Armenian Patriarchate of Jerusalem) has followed the Gregorian Calendar since 1923, making it and the Finnish Orthodox church the only Orthodox churches to primarily celebrate Easter on the same date as Western Christianity. As a result, the Armenian church's observation of Lent generally begins and ends before that of other Orthodox churches.
