As an expression of lamentation and/or penitence, fasting nearly always is associated with weeping ( Judges 20:26 ; Esther 4:3 ; Psalm 69:10 ; Joel 2:12 ), confession ( 1 Sam 7:6 ; Dan 9:3 ), and the wearing of sackcloth ( 1 Kings 21:27 ; Neh 9:1 ; Esther 4:3 ; Psalm 69:10 ; Dan 9:3 ). In the New Testament Jesus chides the hypocritical Pharisees for disfiguring their faces when they fast ( Matt 6:16-18 ), a reference no doubt to the custom of smearing themselves with ashes. These objects and actions had no intrinsic penitential value but in a culture in which inner feelings were commonly displayed or even dramatized, when done sincerely they effectively communicated contrition. It became easy, however, for the outward exhibition of repentance to take the place of a genuine, inner attitude and thus become an act of hypocrisy.
Chris Pratt! Hugh Jackman! Halle Berry! Kourtney Kardashian! What these celebrities have in common, other than a gratuitous exclamation point after their names, is a professed fondness for intermittent fasting, the diet craze turning the fitness world on its sweaty, well-toned head. For help determining whether you, too, should incorporate this into your 2019 resolution-related plans, we asked a few experts to explain what it is, why people love it, and whether it’s really worth the pain of forgoing on-demand snacks for the rest of the winter.
Keep in mind that the initial weight lost on a fast is primarily fluid or "water weight," not fat. And when you go back to eating, any lost weight usually gets a return ticket back. Not only do most people regain weight lost on a fast, they tend to add a few extra pounds because a slower metabolism makes it easier to gain weight. Worse, the weight that is regained is likely to be all fat -- lost muscle has to be added back at the gym.
In addition to the fasts mentioned above, Roman Catholics must also observe the Eucharistic Fast, which involves taking nothing but water and medicines into the body for one hour before receiving the Eucharist. The ancient practice was to fast from midnight until Mass that day, but as Masses after noon and in the evening became common, this was soon modified to fasting for three hours. Current law requires merely one hour of eucharistic fast, although some Roman Catholics still abide by the older rules.
As far back as the 1930s, scientists have been exploring the benefits of reducing calories by skipping meals. During that time, one American scientist found that significantly reducing calories helped mice live longer, healthier lives. More recently, researches have found the same in fruit flies, roundworms and monkeys. Studies have also shown that decreasing calorie consumption by 30 to 40 percent (regardless of how it’s done) can extend life span by a third or more. Plus, there’s data to suggest that limiting food intake may reduce the risk of many common diseases. Some believe fasting may also increase the body’s responsiveness to insulin, which regulates blood sugar and helps control hunger.
But while these diets have gained popularity, there have been only a few longitudinal studies on whether they actually lead to sustained weight loss. (U.S. News & World Report has a breakdown of past research into fasting diets.) Now there’s a new credible study to add to the mix: This 50-week study of 150 obese and overweight adults published in The American Journal Of Clinical Nutrition found that the 5:2 fasting diet was “equivalent but not superior to” conventional dieting in terms of weight loss and the prevention of metabolic diseases.

6. Are you hungry all the time? A scale of 1 to 10 is helpful in moments like this. One is ravenous, while 10 is extremely full. What is your number before and after meals? What is your number at moments during the fast? While hunger may be part of a fast given the caloric restriction, it shouldn’t be constant, ongoing and terrible. Also, notice portions when eating. If you haven’t created the right balance, you might overeat when breaking a fast, which is hard on your digestion and metabolism. Ideally, once acclimated, you’d stay within the 3 to 7 range at all times, 3 when fasting and 7 after meals.
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”.
Jesus’ statements concerning fasting are simple and straightforward. His disciples will fast (Luke 5:33-35 Luke 5:33-35 33 And they said to him, Why do the disciples of John fast often, and make prayers, and likewise the disciples of the Pharisees; but your eat and drink? 34 And he said to them, Can you make the children of the bridal chamber fast, while the bridegroom is with them? 35 But the days will come, when the bridegroom shall be taken away from them, and then shall they fast in those days.

Fasting is not the first dietary approach to excite researchers. Before fasting, there was caloric restriction, or CR. The methods have much in common. Overall, they both drastically reduce energy intake and bring about similar health benefits. They’re like siblings in a way, especially since fasting studies emerged from work on CR. And now, many former CR researchers are exploring fasting, often setting the two against each other in the lab.


The Bible gives examples of God’s people occasionally combining fasting with their prayers so as to stir up their zeal and renew their dedication and commitment to Him. King David wrote that he “humbled [him]self with fasting” (Psalms 35:13 Psalms 35:13But as for me, when they were sick, my clothing was sackcloth: I humbled my soul with fasting; and my prayer returned into my own bosom.
Why try a plan with a high dropout rate and hours of hunger? Beyond the health benefits, some people actually like it—and find it the easiest way to control their weight. Mark Mattson, Ph.D., a neuroscientist at the National Institute on Aging, has studied intermittent fasting since the 1990s and himself been on a plan for years. "Once you get used to it, it's not a big deal," he says. "You adapt." Other fans? Reportedly, trendsters from Beyonce to Silicon Valley techies; and Jimmy Kimmel has said he lost 25 pounds fasting too. So... should you experiment?
There are MUCH bigger fish to fry with regards to getting healthy than a few calories here and there during a fast. 80% adherence that you stick with for a year is better than 100% adherence that you abandon after a month because it was too restrictive. If you’re trying to get to a minimum bodyfat percentage, you’ll need to be more strict – until then, however, do what allows you to stay compliant!
And that's not all, says Courtney Peterson, Ph.D., an assistant professor in the department of nutrition sciences at the University of Alabama at Birmingham. "Studies suggest you keep more muscle and lose more fat than on other diets, even if you lose the same number of pounds." That's because after about 12 hours of fasting, you run out of stored energy from carbs and start burning stored fat.
Prepare yourself to encounter God through fasting. When you realize that your intimacy with God is superficial and you long to experience Him more directly, respond by fasting, and you may find that you encounter God more deeply and powerfully. Through fasting, render yourself freer to hear from God through prayer than you may be when you’re not fasting. Let your love for God motivate you to reach out to Him through fasting.
Hold morning worship. Worship Him and praise Him for His attributes. Read God’s Word, and meditate that God will lend me His Wisdom, so that I can input His Word into my life, and I can gain a fuller understanding of it. Pray for God’s Will to be done, and for the guidance of the Holy Spirit. Ask God to lead you in spreading His Glory into the world we live in.
Vitousek, the psychologist, has seen this kind of enthusiasm before — and it was for CR. Caloric restriction never reached fasting’s popularity, but it had its share of lay followers in the 2000s, when she got a chance to talk with members of a group practicing it. Initially, they were excited and motivated. Then, like most dieters, the majority began to fall away. Some who had done CR for years simply couldn’t do it anymore. “You can pretty much take that to the bank,” Vitousek says of dieters’ waning enthusiasm. “That’s why we have these cyclical waves.”
People who use insulin or drugs like metformin need to eat regularly, warns Foroutan. "If you go too long between meals you risk having your blood sugar fall way too low, which could be incredibly dangerous.” Skipping breakfast or avoiding snacks can be especially bad for people with diabetes because having consistent meals can prevent spikes in blood sugar and strengthen the effectiveness of their medication.

What about us? There's an element of good in foods and substances that are ultimately bad for us, even if it's just the good appearance, smell, or taste. Have you ever noticed how beautiful all the colored and distinctly shaped bottles look in a bar? Those bottles always seem lighted in just the right way to make them look very special, very festive, very appealing. Many foods are pleasant to the eyes. Many drinks are presented in ways that make them appear pleasing. We buy into the lie that what is pleasing is also nutritious and beneficial.


How It Works: Not completely satisfied with the IF diets listed above? This method takes the best parts of Eat Stop Eat, The Warrior Diet and Leangains, and combines it all into one plan. You also get one cheat day each week (yay!) — followed by a 36-hour fast (which may be not-so-yay for some). After that, the remainder of the seven-day cycle is split up between the different fasting protocols.
When obese people structured their schedule so that they fasted for 16 hours a day, but were free to eat whatever they wanted in the other eight hours — known as the 16:8 diet, or time-restricted feeding — they modestly lost weight and lowered their blood pressure after 12 weeks on the regimen, a new early study published in the journal Nutrition and Healthy Aging found.
For the uninitiated, intermittent fasting is an eating pattern or a diet regimen that cycles between brief periods of fasting (with either no food or significant calorie reduction) and non-fasting over a defined period. There are different types of intermittent fasting such as the 16/8 method, the 5:2 diet, eat-stop-eat -- all of which involve vary in the number of fast days and calorie portions. But if you’re a newbie faster and trying to lose weight or do away with that unhealthy visceral fat using the intermittent fasting, most of them can seem too extreme for you. But fret not, here’s one that’s considered best for beginners - the 12:12 method. Let’s try to figure out what exactly is the 12:12 fasting and how does it help with weight loss.

Among the Western religions, only Zoroastrianism prohibits fasting, because of its belief that such a form of asceticism will not aid in strengthening the faithful in their struggle against evil. The other Western religions—Judaism, Christianity, and Islam—emphasize fasting during certain periods. Judaism, which developed many dietary laws and customs, observes several annual fast days, primarily on days of penitence (such as Yom Kippur, the Day of Atonement) or mourning. Christianity, especially Roman Catholicism and Eastern Orthodoxy, has observed a 40-day fast period during Lent, a spring period of penitence before Easter, and during Advent, a penitential period before Christmas. Among Roman Catholics the observance has been modified since the Second Vatican Council (1962–65) to allow greater individual choice, with mandatory fasting only on Ash Wednesday and Good Friday during Lent. Protestant churches generally leave the decision to fast to individual church members. The month of Ramadan in Islam is a period of penitence and total fasting from dawn to dusk.

The combination of fasting and praying is not a fad or a novelty approach to spiritual discipline. Fasting and praying are not part of a human-engineered method or plan. They are not the means to manipulate a situation or to create a circumstance. Fasting and praying are Bible-based disciplines that are appropriate for all believers of all ages throughout all centuries in all parts of the world.
Research more about IF and learn outside of what I share to see if there is a different style of IF that is a better fit for you and your needs. While there is widely available research on the benefits of IF, you should also learn more about the potential of negative effects of fasting on sleep, alertness, cognitive-motor performance, mood and for those with a previous history or susceptibility with eating disorders.
Fasting should not be considered a "dieting method" either. We shouldn't fast to lose weight, but rather to gain deeper fellowship with God. Yes, anyone can fast. Some may not be able to fast from food (diabetics, for example), but everyone can temporarily give up something in order to focus on God. Even unplugging the television for a period of time can be an effective fast.

Making sure you’re hydrated in general is not only healthy, but can also help stave off hunger. Drinking water before a meal and during the day can help temporarily stave off hunger pangs by putting something in your stomach. Plus, water helps keep your body functioning properly throughout the day. When you’re fasting, remember to get plenty of fluids.
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.

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."
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.
During the Biosphere 2 experience and the Calerie trial, some researchers hoped CR would become a viable regimen. But the enthusiasm has significantly cooled. While side effects were an issue, people’s inability to stick to a significantly reduced calorie load every day was the hammer blow. At this point, fasting was CR’s heir apparent: It seems eating nothing on occasion might be better than eating less all the time.

It doesn't matter when you start your 8–hour eating period. You can start at 8am and stop at 4pm. Or you start at 2pm and stop at 10pm. Do whatever works for you. I tend to find that eating around 1pm and 8pm works well because those times allow me to eat lunch and dinner with friends and family. Breakfast is typically a meal that I eat on my own, so skipping it isn't a big deal.


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.
The Vajrayana practice of Nyung Ne is based on the tantric practice of Chenrezig.[29][30][31] It is said that Chenrezig appeared to an Indian nun[29] who had contracted leprosy and was on the verge of death. Chenrezig taught her the method of Nyung Ne[29] in which one keeps the eight precepts on the first day, then refrains from both food and water on the second. Although seemingly against the Middle Way, this practice is to experience the negative karma of both oneself and all other sentient beings and, as such is seen to be of benefit. Other self-inflicted harm is discouraged.[32][33]
