When Varady and her colleagues conducted a study that combined alternate day fasting and exercise, they allowed the participants to pick whether they wanted to exercise on a feasting or fasting day, and found there was no strong preference one way or the other. But the researchers were surprised the dieters actually reported feeling more energetic on fasting days.
Once or twice per week you can have a treat. Remember you will have 600-1000 calories to work with in the main meal. This should make it pretty easy to enjoy some of your favorite foods or go out to a restaurant with friends/family. Just make sure to not go over the calorie budget for the day. If you do end up going over the calorie budget for the day then you can compensate by slightly reducing calories the following days.
Surprisingly, since I've started intermittent fasting I've increased muscle mass (up 10 pounds from 205 to 215), decreased body fat (down 3% from 14% to 11%), increased explosiveness (set a personal best with a clean and jerk of 253 pounds a few months back), and decreased the amount of time I've spent training (down from 7.5 hours per week to 2.5 hours per week).
About that: People don’t usually binge that much on their feed day. “Most people report they can only eat about 10% more coming off a fast than they normally would—their body just won’t let them overeat,” Varady says. That’s why an increasing number of studies show that intermittent fasting may work just as well as limiting your calorie intake when it comes to weight loss.
One potential disadvantage of this schedule is that because you typically cut out a meal or two out of your day, it becomes more difficult to get the same number of calories in during the week. Put simply, it's tough to teach yourself to eat bigger meals on a consistent basis. The result is that many people who try this style of intermittent fasting end up losing weight. That can be a good thing or a bad thing, depending on your goals.

To keep my energy levels up during strength training, I use a couple of pre-workout supplements: For energy and pump I take Naked Energy (It’s Keto Approved), and for strength and endurance I mix in a scoop of Julian Bakery exogenous ketones. I have found that this really takes my workouts to the next level. I always suggest getting these two supplements to anyone that wants to get into keto.

AN IMPORTANT CAVEAT: Intermittent Fasting can be more complex for people who have issues with blood sugar regulation, suffer from hypoglycemia, have diabetes, etc. If you fit into this category, check with your doctor or dietitian before adjusting your eating schedule. It also affects women differently (there’s a whole section dedicated to that below)

The drawbacks were clear. The men became obsessed with food to the exclusion of everything else in their life, and when the calorie restriction ended, they all over-reacted. Within a few weeks, they regained all of the lost weight plus about 10 percent more. Other studies have come to similar conclusions. So starvation-type diets may not be ideal for the average person. Your body will tend to shut down various processes in order to survive. For example, by reducing thyroid function, your body will not burn as many calories.
The problem is that too many people jump on the fasting bandwagon without understanding how to assess its impact. Once a plan has been integrated into your everyday life, you should take time every week or month to analyze how things are going. Even if weight loss is your primary goal, it’s important to consider how fasting is affecting other aspects of your health, such as your energy levels, ability to exercise and digestion. Here are some questions you should ask yourself.

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.
Research7,8,9 has shown that intermittent fasting results in many of the same benefits as calorie restriction — even if you don't place any restrictions on the number of calories you consume when you do eat. This was demonstrated in a 2013 review,10 which found a broad range of therapeutic benefits of intermittent fasting, even when total calorie intake per day did not change, or was only slightly reduced. Research included in that review, and other published studies, indicate that intermittent fasting can help:
Fasting ramps up your stem cell production.[6] Stem cells are like biological playdough — your body turns them into any kind of cell it needs and uses them to replace old or damaged cells, keeping you younger on a cellular level. Stem cells are great for your skin, joints, old injuries, chronic pain, and more. You can try stem cell therapy…or you can just fast.

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 problem is that too many people jump on the fasting bandwagon without understanding how to assess its impact. Once a plan has been integrated into your everyday life, you should take time every week or month to analyze how things are going. Even if weight loss is your primary goal, it’s important to consider how fasting is affecting other aspects of your health, such as your energy levels, ability to exercise and digestion. Here are some questions you should ask yourself.


Fasting must also be done in an attitude of humility. It is not necessary for others to know we are fasting; it is directed towards God. “But when you fast, put oil on your head and wash your face, so that it will not be obvious to men that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you” (Matthew 6:17-18).
Time-restricted eating is pretty simple to implement. If you finish dinner at 7 p.m., for instance, you wouldn’t eat anything again until at least 7 a.m. If you wanted to take it further, you’d extend the no-eating time until about 11 a.m. or 12 p.m. Because you’re sleeping for a large chunk of the “no eating” time, this is a good way to introduce fasting into your lifestyle and experiment without any major changes.

For this plan, eat clean for five days of the week (you can pick whatever days you want). On the other two days, restrict your calories to no more than 700 each day. Calorie restriction unlocks a lot of the same benefits as fasting for an entire day. On your non-fasting days, you’ll need to make sure you're getting in healthy fats, clean meats, vegetables, and some fruits, and you can structure your meals however best works for you. On restricted days you can have smaller meals or snacks throughout the day or have a moderate-size lunch and dinner and fast in the morning and after dinner. Again, focus on healthy fats, clean meats, and produce. An app like MyFitnessPal can help you log your food and keep track of your calorie intake so you don’t go over 700.

That said, I have heard that women may find a wider window of eating to be more favorable when doing daily intermittent fasting. While men will typically fast for 16 hours and then eat for 8 hours, women may find better results by eating for 10 hours and fasting for 14 hours. The best advice I can give anyone, not just women, is to experiment and see what works best for you. Your body will give you signals. Follow what your body responds favorably to.
Often fasting is done for medical or health reasons, or in an attempt to lose weight. For many other people, fasting is an important part of their religious observance. Fasting is done by Muslims, Christians, Buddhists, and Jews, among other groups. Fasting comes from fast, which in turn has an Old English root, fæsten, "voluntary abstinence from food or drink, especially as a religious duty."
^ Jacobs, Henry Eyster; Haas, John Augustus William (1899). The Lutheran Cyclopedia. Scribner. p. 110. By many Lutherans Good Friday is observed as a strict fast. The lessons on Ash Wednesday emphasize the proper idea of the fast. The Sundays in Lent receive their names from the first words of their Introits in the Latin service, Invocavit, Reminiscere, Oculi, Lcetare, Judica.

When Varady and her colleagues conducted a study that combined alternate day fasting and exercise, they allowed the participants to pick whether they wanted to exercise on a feasting or fasting day, and found there was no strong preference one way or the other. But the researchers were surprised the dieters actually reported feeling more energetic on fasting days.
^ McKnight, Scot (2010). Fasting: The Ancient Practices. Thomas Nelson. p. 88. ISBN 9781418576134. John Wesley, in his Journal, wrote on Friday, August 17, 1739, that "many of our society met, as we had appointed, at one in the afternoon and agreed that all members of our society should obey the Church to which we belong by observing 'all Fridays in the year' as 'days of fasting and abstinence.'
Fasts may last for varying lengths of time -- one day, three days, seven days, and more. We should prayerfully seek the Lord about the length of our fast. Fasting should have an object in mind; we should have a clear idea of the need and purpose. One of the most pressing reasons for Christian fasting may be revival -- “Will you not revive us again...” (Psalm 85:6).
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.
Eating all your meals in an 8-hour window (say, eating between noon and 8PM, and fasting the other 16 hours a day) causes significant weight loss without counting calories.[1]  While this type of intermittent fasting causes weight loss no matter what people eat, research shows that people who do it in a healthy manner lose twice as much weight (7% vs. 3% of their body weight) as those who fast while still eating junk. So it’s still important to follow a high-performance diet like the Bulletproof Diet while you fast.

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.


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.
All three types offer the same fat-burning benefits of intermittent fasting. The real differences are just in how long you’re fasting and what you’re allowed to eat during the fast, Varady says. On both whole-day fasting and alternate-day fasting, for example, you consume 500 calories per fast day to spark fat loss but maintain muscle. During time-restricted feeding, however, you’re consuming zero calories during your fast period (water and tea, for example, are allowed). In all types, you’re free to go hog-wild during the feeding window—though, obviously, all nutritionists would recommend you ditch the junk and stick to healthy fare.

This is the same as the 8-to-6 window plan, but you are extending your fasting time an extra four hours. I personally practice this plan during the workweek. I'm not a breakfast person, so I just enjoy a few cups of herbal tea to start my day. With this plan you will be eating only between the hours of 12 p.m. and 6 p.m. for a full 18 hours of fasting within a 24-hour period.

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.

Dr. Michael Mosley popularized this variation of intermittent fasting in his book ‘The Fast Diet’. This involves 5 regular eating days and 2 fasting days. However, on these two fasting days, it is permitted to eat 500 calories on each day. These calories can be consumed at any time during the day – either spread throughout the day, or as a single meal.
American King James Version×). Daniel and Nehemiah set the example of having a repentant frame of mind (Daniel 9:3-4 Daniel 9:3-4 3 And I set my face to the Lord God, to seek by prayer and supplications, with fasting, and sackcloth, and ashes: 4 And I prayed to the LORD my God, and made my confession, and said, O Lord, the great and dreadful God, keeping the covenant and mercy to them that love him, and to them that keep his commandments;

Alternative medicine A period of voluntary abstinence from foods and/or drinks; fasting is integral to many religions, as it is believed to purify the mind and spirit; fasting rests the GI tract, and may rid the body of toxins and undigested metabolites; fasting leads to a loss of water, Na+, and K+, resulting in postural hypotension, and decreased blood sugar resulting in depression, fatigue, decreased libido, and malaise, increased nitrogen in the circulation due to protein breakdown, and may result in premature childbirth—Yom Kippur effect
Fasting is important, more important perhaps, than many of us have supposed . . . when exercised with a pure heart and a right motive, fasting may provide us with a key to unlock doors where other keys have failed; a window opening up new horizons in the unseen world; a spiritual weapon of God’s provision, mighty, to the pulling down of strongholds. [Arthur Wallis, God’s Chosen Fast].
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.
Biblical fasting is a spiritual discipline which was encouraged by Jesus, Himself, while He was on earth. When questioned as to why the Pharisees and the disciples of John the Baptist fasted while Jesus disciples did not, Jesus answered, "How can the guests of the bridegroom mourn while he is with them? The time will come when the bridegroom will be taken from them; then they will fast” (Matthew 9:15).
Hi Adrian. I hope all is well with you. I was referred to subscribe to your channel last night and I did. Well, not sure where to start BUT... I have been on my journey with weight loss for a while now and on April 16th of this year I decided to try intermittent fasting. I broke my fast a few times the first week but after that I have been doing well, going to the gym and working out 4-5 days a week doing mostly cardio. From what I've been reading and seeing about IF, people are losing 5-8 lbs a week. Me? I've only lost 4.7 lbs. I am happy for the 4.7lbs down but I was thinking that being the weight that I started (245.4 lbs) would mean I would lose the weight faster. No? I also am watching what I eat via MyFitnessPal to help me count my calories. I usually east between 1200 - 1450 calories. There are days that I have eaten a little less but not much. Also I am 5'1. Please help me because I am discouraged and frustrated doing all I think is right with IF but not seeing the maximum results as people have mentioned. What do you think may be the issue here? Also there is nothing wrong with me medically to say that's the reason I am not losing much weight. I hope to hear from you because I really don't want to give up. I am trying to be healthy! Thank you. (I also sent this message to you on YouTube. Not sure which messages you check more frequently).
Tons of celebs are jumping on the intermittent fasting keto bandwagon, and for good reason. The two work hand in hand to accelerate weight loss, not to mention stimulate lots of other performance-boosting benefits. Fasting is an extraordinary tool for improving your biology. It’s free. It’s universally accessible. It’s adaptable. It’s the reason it’s always been a major part of the Bulletproof Diet.
Although it’s possible that fasting helps manage blood sugar and insulin, fight inflammation, and ease sleep problems, most people follow a fasting diet to lose weight. Fasting is believed to help in this goal because of the effects that caloric restriction and extended periods without food have on metabolism, or simply because people eat less during the restricted feeding window. (Some dieters benefit from the structure and clear boundaries fasting plans offer.)
Where diets complicate life, fasting simplifies. Where diets are expensive, intermittent fasting is free. Where diets can take time, fasting saves time. Where diets are limited, fasting is available anywhere. Where diets have variable efficacy, fasting has unquestioned efficacy. There is no more powerful method for lowering insulin and decreasing body weight.

You’ll run out of energy. When you don’t have anything in your system for several hours, your blood sugar will eventually drop below baseline. If you’ve ever had a blood sugar crash, you know how this state feels. Sleepiness, trouble focusing, lightheadedness, intense cravings, and the occasional mood swing typically accompany low blood sugar. Your cells run low on fuel and they start demanding that you give them more carbs.[13]

Fasting has been used in Europe as a medical treatment for years. Many spas and treatment centers, particularly those in Germany, Sweden, and Russia, use medically supervised fasting. Fasting has gained popularity in American alternative medicine over the past several decades, and many doctors feel it is beneficial. Fasting is a central therapy in detoxification, a healing method founded on the principle that the build up of toxic substances in the body is responsible for many illnesses and conditions.
3. How are your labs? Are measures such as your cholesterol and blood sugar levels moving in the right direction, and all in healthy ranges? Also, many fasting protocols can be low in certain nutrients. Using labs to look at micronutrients, such as vitamins, minerals, and essential fatty acids and amino acids is essential to ensure that your intake is sufficient.
Physiologically, calorie restriction has been shown in animals to increase lifespan and improve tolerance to various metabolic stresses in the body. [4] Although the evidence for caloric restriction in animal studies is strong, there is less convincing evidence in human studies. Proponents of the diet believe that the stress of intermittent fasting causes an immune response that repairs cells and produces positive metabolic changes (reduction in triglycerides, LDL cholesterol, blood pressure, weight, fat mass, blood glucose). [3,5] An understandable concern of this diet is that followers will overeat on non-fasting days to compensate for calories lost during fasting. However, studies have not shown this to be true when compared with other weight loss methods. [5]
So what accounts for this heightened mental state? It seems fasting triggers a dramatic switch in the body’s metabolism, according to a paper Mattson and colleagues published in February in the experimental biology journal FASEB. In humans, fasting for 12 hours or more drops the levels of glycogen, a form of cellular glucose. Like changing to a backup gas tank, the body switches from glucose to fatty acids, a more efficient fuel. The switch generates the production of ketones, which are energy molecules that are made in the liver. “When the fats are mobilized and used to produce ketones, we think that is a key factor in accruing the health benefits,” says Mattson.
It’s a good idea to weigh yourself before starting (and then again at the same time each week), and also to take chest, waist and hip measurements. The rate that you’ll lose depends on your age, levels of activity and your own body – so don’t be disheartened if you’re losing a pound a week while others are losing five or more. Typically weight loss will be faster at the beginning of the diet, and for those with a lot of weight to lose to reach a healthy weight (see this calculator to find out what a healthy weight - or BMI - is for someone of your height and weight).

Tisha B'Av and Yom Kippur are the major fasts and are observed from sunset to the following day's dusk. The remaining four fasts are considered minor and optional fasting is only observed from sunrise to dusk.[90] Both men and women can choose to observe them,[91] and a rabbi may give a dispensation if the fast represents too much of a hardship to a sick or weak person, or pregnant or nursing woman.
Just began this 16:8 IF with Keto. I track macros and split them into two meals for my eating window. It works out to 40grams of protein each meal.. Isn’t this a lot of protein in one meal? Should I do less than my macros say because it’s two meals instead of three? Just checking because I thought I read somewhere about not consuming too much protein in a meal. Thank you.
Those studies above, in working with small sample sizes, and different types of fasting than recommended here, would lead me to believe that fasting affects men and women differently, and that many of the weight loss benefits associated with intermittent fasting (that affect insulin and glucose responses) work positively for men and negatively for women.

Cost isn't really a factor for the Fast Diet, given that you're eating normally most days. There's a good chance you'll wind up buying fewer foods on fast days, and thus spend less on your grocery bills. But keep in mind that if you follow the diet authors' advice and get your calories from high-quality foods, they can be a bit pricier than cheap, high-calorie fast-food cheeseburgers.
It can level up your brain, including positively counteracting conditions like Parkinson’s, Alzheimer’s, and dementia. As explained here in this TEDx talk by Mark Mattson, Professor at Johns Hopkins University and Chief of the Laboratory of Neurosciences at the National Institute on Aging fasting is grounded in serious research and more studies are coming out showing the benefits:

What is ghrelin? It is actually also known as the hunger hormone, because it is responsible for telling your body that it is hungry. Dieting and really restrictive eating can actually increase ghrelin production, which will leave you feeling hungrier. But when you fast, though you might struggle in the first few days, you’re actually normalizing ghrelin levels.
^ Epps, David (20 February 2018). "Facts about fasting". The Citizen. Retrieved 16 March 2018. In Methodism, fasting is considered one of the “Works of Piety.” The Discipline of the Wesleyan Methodist Church required Methodists to fast on certain days. Historically, Methodist clergy are required to fast on Wednesdays, in remembrance of the betrayal of Christ, and on Fridays, in remembrance of His crucifixion and death.

The Old Testament law specifically required prayer and fasting for only one occasion, which was the Day of Atonement. This custom became known as "the day of fasting" (Jeremiah 36:6) or "the Fast" (Acts 27:9). Moses fasted during the 40 days and 40 nights he was on Mount Sinai receiving the law from God (Exodus 34:28). King Jehoshaphat called for a fast in all Israel when they were about to be attacked by the Moabites and Ammonites (2 Chronicles 20:3). In response to Jonah's preaching, the men of Nineveh fasted and put on sackcloth (Jonah 3:5). Prayer and fasting was often done in times of distress or trouble. David fasted when he learned that Saul and Jonathan had been killed (2 Samuel 1:12). Nehemiah had a time of prayer and fasting upon learning that Jerusalem was still in ruins (Nehemiah 1:4). Darius, the king of Persia, fasted all night after he was forced to put Daniel in the den of lions (Daniel 6:18).
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.
Another big concern of mine, but it turns out this fear was unfounded. We’ve been told by the supplement industry that we need to consume 30 g of protein every few hours, as that’s the most amount of protein our body can process at a time. Along with that, we’ve been told that if we don’t eat protein every few hours, our body’s muscle will start to break down to be burned as energy.
Secular Music Fast: Instead of listening to Top Hits on the radio, you can choose to listen to the Christian radio station for a period of time. Pop in a CD of your favorite worship leader when you're driving to work. Listen to a Christian podcast or audiobook. You can even turn the stereo off completely and spend that time in prayer. You'll be amazed what this little change will do for your life. 
Fasting is practiced by lay Buddhists during times of intensive meditation, such as during a retreat. During periods of fasting, followers completely stray away from eating animal products although, they do allow consumption of milk. Furthermore, they also avoid eating processed foods and the five pungent foods which are; garlic, welsh onion, garlic chives, asana, leeks.[26] The Middle Path refers to avoiding extremes of indulgence on the one hand and self-mortification on the other. Prior to attaining Buddhahood, prince Siddhartha practiced a short regime of strict austerity and following years of serenity meditation under two teachers which he consumed very little food. These austerities with five other ascetics did not lead to progress in meditation, liberation (moksha), or the ultimate goal of nirvana. Henceforth, prince Siddhartha practiced moderation in eating which he later advocated for his disciples. However, on Uposatha days (roughly once a week) lay Buddhists are instructed to observe the eight precepts[27] which includes refraining from eating after noon until the following morning.[27] The eight precepts closely resemble the ten vinaya precepts for novice monks and nuns. The novice precepts are the same with an added prohibition against handling money.[28]
