Boosts metabolism: Intermittent fasting also boosts protein, fat, and glucose metabolism in animal studies. Boosting your resting metabolism helps your body burn more calories throughout the day, even while you rest. Fasting also increases your levels of adrenaline and noradrenaline, hormones that help your body free up more stored energy (that’s your body fat) during a fast.[10][11]

1) A soul cleansing. How often we forget that our bodies are the temple of the Lord—especially when deciding what to eat! Fasting is a great time to remember the spiritual connection we have to our physical bodies. Without the toxins we put in our bodies, we not only give our bodies a break from the digestive process, but we also allow our spirits to be detoxed.  Fasting is a faith-move, an expectation we have that God will fill us with His Holy Spirit, just as He promised. But as Christ told His disciples, “[N]o one pours new wine into old wineskins. Otherwise, the wine will burst the skins, and both the wine and the wineskins will be ruined. No, they pour new wine into new wineskins." By fasting, we meditate cleanses the soul and makes it new so we can receive the Holy Spirit and become empowered to live for Christ in a new way.
Of the two most popular methods, Sasson leans toward the 5:2 schedule as slightly more manageable, since you’re only reducing your intake twice a week. But again, that’s contingent on you being a responsible dieter on your days of lowered caloric intake, which requires an immense amount of discipline—especially when it comes to remembering to drink water. “You can go a long time without food, but only a few days without adequate hydration,” she warns.
Fasting has been used therapeutically since at least the 5th century bce, when Greek physician Hippocrates recommended abstinence from food or drink for patients who exhibited certain symptoms of illness. Some physicians recognized a fasting instinct, whereby patients in certain disease states naturally experience a loss of appetite. Some physicians believed that administering food during such states was unnecessary and possibly even detrimental, since fasting was thought to be an important natural part of the recovery process.
In related news, recent research3 suggests drinking 500 ml (a little more than two eight-ounce glasses) of water half an hour before your meals may help boost weight loss. Obese participants who "pre-loaded" with water before each meal lost an average of nearly three pounds (close to 1.5 kilos) more than the control group over the course of three months.
Zero-calorie beverages are okay.  I drink green tea in the morning for my caffeine kick while writing. If you want to drink water, black coffee, or tea during your fasted period, that’s okay.  Remember, don’t overthink it – keep things simple! Dr. Rhonda Patrick over at FoundMyFitness believes that a fast should stop at the first consumption of anything other than water, so experiment yourself and see how your body responds.
According to a research published in Cell Metabolism, fasting for 12+ hours most days may promote weight loss, prevent disease and promote longevity. The researchers, who divided the mice into four diet groups and categorised them into different feeding schedules, found that mice fasted for at least 12 hours and kept their eating within a set 12-hour time frame experienced significant weight loss compared to mice eating the same diet but with liberty to eat all day long. 
The Church of the East strictly observes the Nineveh Fast (Som Baoutha). This annual observance occurs exactly three weeks before the start of Lent. This tradition has been practised by all Christians of Syriac traditions since the 6th century. At that time, a plague afflicted the region of Nineveh, modern-day northern Iraq. The plague devastated the city and the villages surrounding it, and out of desperation the people ran to their bishop to find a solution. The bishop sought help through the Scriptures and came upon the story of Jonah in the Old Testament. Upon reading the story, the bishop ordered a three-day fast to ask God for forgiveness. At the end of the three days, the plague had miraculously stopped, so on the fourth day the people rejoiced.
Even though you are skipping breakfast, it's still important to stay hydrated. Make sure to still drink enough water. You can also have herbal tea. The catechins in tea have been shown to enhance the benefits of fasting by helping to further decrease the hunger hormone ghrelin, so you can make it until lunch and not feel deprived. Since you’ve increased your fasting period an extra four hours, you need to make sure your first meal (at noon) has enough healthy fats. The burger in the 8-to-6 window plan will work well, and you can add more fats in with your dressing or top with an avocado!
The very simple and direct conclusions I draw are these: First, if the Bible teaches us to do something, I want to do it. I want to obey the Lord in every way that He commands me to obey Him. And second, if fasting and praying are means to a breakthrough that God has for me, I want to undertake those disciplines so I might experience that breakthrough!
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.

John Calvin, the figurehead of the Reformed tradition (the Continental Reformed, Congregational, Presbyterian, and Anglican Churches) held that communal fasts "would help assuage the wrath of God, thus combating the ravages of plague, famine and war."[63] In additional, individual fasting was beneficial in that "in preparing the individual privately for prayer, as well as promoting humility, the confession of guilt, gratitude for God's grace and, of course, discipling lust."[63] As such, many of the Churches in the Reformed tradition retained the Lenten fast in its entirety.[36] The Reformed Church in America describes the first day of Lent, Ash Wednesday, as a day "focused on prayer, fasting, and repentance" and considers fasting a focus of the whole Lenten season,[71] as demonstrated in the "Invitation to Observe a Lenten Discipline", found in the Reformed liturgy for the Ash Wednesday service, which is read by the presider:[72]
Is fasting worth the effort? A recent metanalysis combined the results of six studies of intermittent fasting found the average weight loss of 15.4 pounds was equal to continuous dieting but both were significantly better than no treatment. It’s hard to draw definitive conclusions based on the results of six studies. Since fasting is difficult for most people, even if it proved to be effective, it might not be a long-term solution to weight control. The 5:2 diet would be more acceptable than a strict fast but many folks would still be miserable on Mondays and Thursdays if they tried to follow Jimmy Kimmel’s example.
But here’s something important to note about what we know from science about fasting: Though a lot of the popular interest is in weight loss, many of the key researchers who study fasting aren’t focusing on that at all. In fact, many of the studies on fasting come from institutes of aging, like this one, and the researchers behind the studies actually focus on longevity and disease prevention.
Through evolution, the body became very efficient at storing energy and handling situations when no food was available. For many centuries, fasting was probably a normal occurrence for most people, and the body adapted to it. It is estimated that even very thin people can survive for 40 days or more without food. The body has a special mechanism that is initiated when no food is eaten. Fasting is not starvation, but rather the body's burning of stored energy. Starvation occurs when the body no longer has any stored energy and begins using essential tissues such as organs for an energy source. Therapeutic fasts are stopped long before this happens.

Once you start your IF journey, you’ll most likely find that you feel fuller longer and can keep the meals you do eat very simple. There are a few different ways you can fast, so I broke up each of the different plans below into beginner, intermediate, and advanced along with a typical meal plan for each day. The combination of nutrients will give you the energy you need to enhance the benefits of your fasting journey. Just make sure to take into account any individual food intolerances, and use this as a guide for your particular health case, and adjust from there.


Body mass index, or BMI, uses height and weight to determine how healthy a person’s weight is. (To calculate, multiply weight in pounds by 703, divide by height in inches, then divide again by height in inches.) Though it doesn’t measure body fat, BMI has been shown to correlate closely with metabolic and disease risks. In general, health risks rise for people with BMIs of 30 and above or below 18.5.

Another type of intermittent fasting, alternate day fasting has you severely restricting the amount of calories you eat during fasting days, then eating to your stomach’s content on non-fasting days. Food isn’t completely off the table, but you’ll stick to about 25 percent of your normal caloric intake. Someone eating 2,000 calories would cut back to 500, for example. Alternate-day fasting isn’t necessarily a long-term plan, because it can become difficult to stick to, but it can be helpful to get a healthy habit in motion.

For some, fasting may be easier to maintain if viewed as a semi-regular activity throughout the week. If you don’t think you can cut down on calories every day of the week at first, try a low-calorie fast for only two days a week. However, you have to be careful about this schedule: just because you’re not fasting every day doesn’t mean that your “off days” should be used to binge on high calorie foods. 
This is probably a good time to mention that while I have practiced intermittent fasting consistently for the last year, I'm not fanatical about my diet. I work on building healthy habits that guide my behavior 90% of the time, so that I can do whatever I feel like during the other 10%. If I come over to your house to watch the football game and we order pizza at 11pm, guess what? I don't care that it's outside my feeding period, I'm eating it.
fast, rapid, swift, fleet, quick, speedy, hasty, expeditious mean moving, proceeding, or acting with celerity. fast and rapid are very close in meaning, but fast applies particularly to the thing that moves fast horses and rapid to the movement itself. rapid current swift suggests great rapidity coupled with ease of movement. returned the ball with one swift stroke fleet adds the implication of lightness and nimbleness. fleet runners quick suggests promptness and the taking of little time. a quick wit speedy implies quickness of successful accomplishment speedy delivery of mail and may also suggest unusual velocity. hasty suggests hurry and precipitousness and often connotes carelessness. a hasty inspection expeditious suggests efficiency together with rapidity of accomplishment. the expeditious handling of an order
Additionally, alternate-day fasting and whole-day fasting have been shown to not only reduce body fat but also total cholesterol and triglycerides in both overweight and normal-weight people, according to a study analysis in Nutrition Reviews. Because intermittent fasting can stabilize insulin levels—if you don’t eat, your blood sugar will come down—there’s reason to believe it could be a good diet for people with Type 2 diabetes, Varady adds. Research also suggests that intermittent fasting may even help prevent Alzheimer’s and cancer, adds Fung.
In her blog, Gospel Taboo, Amanda Edmondson writes, "Biblically, fasting is mentioned in both the Old and New Testament. In the Old Testament it was often a way of expressing grief or a means of humbling one's self before the Lord. In Psalm 35:13, David humbled himself with fasting. In the New Testament it was a means to grow closer to God through mediating and focusing on Him. In Matthew 4:1-2, Jesus went to the wilderness to fast for 40 days. In Matthew 6:16-18 we learn that we aren’t to look somber while fasting so that it’s not obvious to others when we are fasting. Throughout the New Testament fasting and prayer are often mentioned together. In Acts 13:3, ‘they had fasted and prayed.’ In Luke 2:37 a widow worshiped day and night fasting and praying."
You’ll eat lunch and dinner within a six-hour window, which gives you an 18-hour fast. Most people will have no problem intermittent fasting every day. Some women may need to do intermittent fasting every other day or a couple of times a week and build up from there. You can learn more about intermittent fasting and women here. The key is to experiment to see what works for you.
Now I'm certainly not linking the devil to a piece of pie, but I am saying this: the devil will always call your attention repeatedly to the thing that is harmful for you, but he will do it in a way that makes you feel deprived if you don't indulge in eating, drinking, or partaking of what is harmful. The implication of the devil is always: "This is so good. Has God really said you can't have any of this good thing?"
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.

If you have an addictive relationship with food and you struggle with portion control, track your calorie intake in your meals to make sure you’re not overeating. If you skip breakfast, you might be so hungry from this that you OVEREAT for lunch and this can lead to weight gain. Again, the important thing here is that with intermittent fasting you’re eating fewer calories than normal because you’re skipping a meal every day.

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. :(
Most of us have contemplated going on a diet. When we find a diet that appeals to us, it seems as if it will be a breeze to do. But when we get into the nitty gritty of it, it becomes tough. For example, I stay on a low–carb diet almost all the time. But if I think about going on a low–fat diet, it looks easy. I think about bagels, whole wheat bread and jelly, mashed potatoes, corn, bananas by the dozen, etc. — all of which sound appealing. But were I to embark on such a low–fat diet I would soon tire of it and wish I could have meat and eggs. So a diet is easy in contemplation, but not so easy in the long–term execution.

Pope Pius XII had initially relaxed some of the regulations concerning fasting in 1956. In 1966, Pope Paul VI in his apostolic constitution Paenitemini, changed the strictly regulated Roman Catholic fasting requirements. He recommended that fasting be appropriate to the local economic situation, and that all Catholics voluntarily fast and abstain. In the United States, there are only two obligatory days of fast – Ash Wednesday and Good Friday. The Fridays of Lent are days of abstinence: eating meat is not allowed. Pastoral teachings since 1966 have urged voluntary fasting during Lent and voluntary abstinence on the other Fridays of the year. The regulations concerning such activities do not apply when the ability to work or the health of a person would be negatively affected.
