On Wednesday and Friday of the first week of Great Lent the meals which are taken consist of xerophagy (literally, "dry eating") i.e. boiled or raw vegetables, fruit, and nuts. In a number of monasteries, and in the homes of more devout laypeople, xerophagy is observed on every weekday (Monday through Friday) of Great Lent, except when wine and oil are allowed.

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.
With this information in hand, you should know exactly how to schedule meals when starting an intermittent fasting plan. And while it might seem complicated at first, once you get into the habit of fasting, it will feel like second nature and fit pretty seamlessly into your days. Just remember to always start slow and gradually work up to more advanced plans.
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.)
Fasts can be performed for varying lengths of time, depending on the person and his or her health requirements. For chronic conditions, therapists recommend from two to four weeks to get the most benefits. Seven-day fasts are also commonly performed. A popular fasting program for prevention and general health is a three-day fast taken four times per year, at the change of each season. These can be easily performed over long weekends. Preventative fasts of one day per week are used by many people as well.
“…a progression should be observed in your fasting, especially if this discipline is new to you and you are unfamiliar with its physical effects. Don’t start out with a weeklong water fast! Begin by skipping one meal each day for two to three days and setting aside the money it would have cost to give to the poor. Spend the time praying that you would have used for eating."
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.
Those fasting may experience side effects of fatigue, malaise, aches and pains, emotional duress, acne, headaches, allergies, swelling, vomiting, bad breath, and symptoms of colds and flu. These reactions are sometimes called healing crises, which are caused by temporarily increased levels of toxins in the body due to elimination and cleansing. Lower energy levels should be expected during a fast.
And because you retain this muscle, your metabolism won’t drop the way it might with calorie-restricted weight loss. In fact, fasting actually boosts your metabolism, says Tinsley. “There’s a misconception that your metabolic rate will decrease if you’re not eating. If you’re fasting, your body views it as a mild stress, so research actually that shows your resting metabolism is actually higher after an overnight fast, and 16-24 hours is the window in which you see the largest increase in fat burn,” he explains.
7. Are you craving foods? Paying attention to your relationship with food during fasting is helpful to assess what’s working and what isn’t to build longer-term habits. For example, having a sweet tooth may be a major issue for you typically, but avoiding sugar and restricting calories may change things. Or maybe you notice you are craving greens or meat or another food. This may be from eliminating so many foods that the body is missing certain nutrients.

In the 1662 Book of Common Prayer, there is a list of "Days of Fasting, or Abstinence," consisting of the 40 days of Lent, the ember days, the three rogation days (the Monday to Wednesday following the Sunday after Ascension Day), and all Fridays in the year (except Christmas, if it falls on a Friday).
Time-restricted feeding (TRF) involves eating only during a certain number of hours each day. A common form of TRF involves fasting for 16 hours each day and only eating during the remaining 8 hours, typically on the same schedule each day. A more liberal practice would be 12 hours of fasting and a 12 hour eating window, or a stricter form would be to eat one meal per day, which would involve around 23 hours of fasting per day.[medical citation needed]
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.
An understanding of the physiological effects of fasting began to evolve in the latter part of the 19th century, when some of the first organized studies of fasting were carried out in animals and humans. In the 20th century, as more became known about nutrition and the nutritional requirements of the human body, methods of fasting became increasingly sophisticated, and a wide array of approaches emerged. For example, fasting was used as a treatment and as a form of disease prevention, and it was carried out in various settings (e.g., in a hospital or clinic or at home). Some fasting methods, particularly those applied in the treatment of chronic diseases, lasted more than a month, allowed for the consumption of only water or calorie-free tea, and included exercise and enemas. Other methods, generally referred to as modified fasting, allowed for the intake of 200 to 500 kilocalories per day (daily calorie needs of adults range from about 1,600 to 3,000 kilocalories, depending on sex, age, and activity level) and sometimes included psychological or spiritual therapy; depending on the particular method used, calories usually were in the form of bread, vegetable broth, fruit juice, honey, or milk. Modified fasting was distinguished from a very low-calorie diet, which allowed up to 800 kilocalories per day and typically was aimed at inducing substantial weight loss. Intermittent fasting involved cyclic periods of calorie restriction, such as a 24-hour period of fasting followed by a 24-hour period of regular calorie consumption.
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. 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. 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.
