I’ll share some of my experiences, now doing heavy strength training for 3 years in a fasted state: For my first “fasted” workout or two after starting an IF protocol, it was very weird to not eat before training. However, after a few sessions, I learned that my body could certainly function (and even thrive) during my training sessions despite not eating a pre-workout meal.
BUT I stopped losing weight since last 2 weeks, so I stopped doing IF for last a week and my tummy looks same as before and I gained 3/4 lbs back. I am trying to do IF again but I cannot, because I’m getting constantly hungry. I used to start Fasting at 7pm & & break at 11/12pm next day. But My new job schedule is from 5:30, so its hard for me to wait until noon. I tried a different schedule from 4pm to 8am but I get hungry at night, so it didn’t help me either. Please help me.
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.
Expect funny looks if you spend a lot of mornings with breakfast eaters.  A few weeks back I had a number of friends staying with me, and they were all completely dumbfounded when I told them I didn’t eat breakfast anymore. I tried to explain it to them but received a bunch of blank stares. Breakfast has become so enGRAINed (zing!) in our culture that NOT eating it sounds crazy.  You will get weird looks from those around you…embrace it. I still go to brunch or sit with friends, I just drink black coffee and enjoy conversation.
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]
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.
Fasting isn't appropriate for everyone and, in some cases, could be harmful. Any person undertaking a first fast longer than three days should seek medical supervision. Those with health conditions should always have medical support during fasting. Plenty of water should be taken by fasters since dehydration can occur. Saunas and sweating therapies are sometimes recommended to assist detoxification, but should be used sparingly. Those fasting should significantly slow down their lifestyles. Taking time off of work is helpful, or at least reducing the work load. Fasters should also get plenty of rest. Exercise should be kept light, such as walking and gentle stretching.

When you’re intermittent fasting, you eat all the food your body needs but during a shorter period of time. There are many methods, but the most common involves eating during a 6- to 8-hour window, and fasting the remaining 14 to 16 hours. It’s not as bad as it sounds, especially when you add Bulletproof Coffee to keep hunger levels in check (more on that later).
A randomized controlled trial that followed 100 obese individuals for one year did not find intermittent fasting to be more effective than daily calorie restriction. [6] For the 6-month weight loss phase, subjects were either placed on an alternating day fast (alternating days of one meal of 25% of baseline calories versus 125% of baseline calories divided over three meals) or daily calorie restriction (75% of baseline calories divided over three meals) following the American Heart Association guidelines. After 6 months, calorie levels were increased by 25% in both groups with a goal of weight maintenance. Participant characteristics of the groups were similar; mostly women and generally healthy. The trial examined weight changes, compliance rates, and cardiovascular risk factors. Their findings when comparing the two groups:

Feelings over hunger may also become more tolerable over time. Studies of alternate-day fasting have shown that people rate their hunger at 8 on a scale of 1 to 10 for their first few fast days, but after two weeks, that number drops to 3. Mattson puts the window at three to four weeks, after which, he says, "you're not hungry on fasting days." (Try clean eating to shed stubborn pounds.

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.
TV/Movie Fast: You can take a break from a weekly favorite and use the time to pray or read the Bible. Is there a small group at church that you've thought about joining but it's during the time your show is on? Do you spend your Saturday binging Netflix when you could take some time to mentor someone God has placed on your heart? This is also a good time to evaluate how much of your time is spent watching TV and whether you need to cut back to make time for other priorities.
“I used to crave foods like crazy when I first started,” says Dr. Sylvia Tara, author of The Secret Life of Fat, in a Bulletproof Podcast episode. “after six to eight weeks, I didn’t feel it anymore.” Dr. Tara kept a journal or foods and schedules to find how fasting worked for her. Her advice for weight loss with intermittent fasting? “For people who have those 20 pounds, know, number one, it can be done. Number two, it might be a bit more effort than you thought it was going to be… Third, know that it gets easier with time and you can maintain it. It really isn’t as bad once you get into it, and it’s extraordinarily effective.”
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.

“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 four-hour eating window — which Hofmekler refers to as the “overeating” phase — is at night in order to maximize the Parasympathetic Nervous System’s ability to help the body recuperate, promoting calm, relaxation and digestion, while also allowing the body to use the nutrients consumed for repair and growth. Eating at night may also help the body produce hormones and burn fat during the day, according to Hofmekler. During these four hours, the order in which you eat specific food groups matters, too. Hofmelker says to start with veggies, protein and fat. After finishing those groups, only if you are still hungry should you tack on some carbohydrates.
Physician Roy Walford was one of the scientists. He also happened to be a CR devotee and had recently written a book on living to the age of 120 by following the regimen. Soon after entering, the team realized the food they raised in the dome wouldn’t be enough to sustain them. So Walford implemented an impromptu CR experiment. The four men and four women reduced their approximate calorie intake by up to 30 percent. It was essentially the first human study of CR and its effects.
Fasting in the Ethiopian Church implies abstention from food and drink. No animal products are consumed, including dairy, eggs and meat, and utensils that have touched such products must be washed before touching the strictly vegan foods that are consumed on fast days. During fast periods, Holy Liturgy (Mass) is held at noon (except on Saturdays and Sundays), and because no food can be consumed before communion, it is traditional for people to abstain from food until mass is over (around 2 to 3 in the afternoon). Every Wednesday and Friday are days of fasting because Wednesday is the day that the Lord was condemned and Friday is the day he was crucified (the Wednesdays and Fridays between Easter Sunday and Pentecost Sunday are an exception as well as when Christmas or Epiphany fall on a Wednesday or a Friday). The fasts that are ordained in the canon of the Church of Ethiopia are:
The main benefit of intermittent fasting is weight loss—fat loss, specifically. “Insulin increases when you eat, and when insulin is high, you cannot burn fat. When you fast, insulin falls, which allows your body to access its stores of food (i.e., body fat) for energy,” explains Jason Fung, M.D., a Toronto-based nephrologist and author of The Complete Guide to Fasting.
3 days in a 16:8 ration – my body loves it. I don’t feel famished and look forward to my 8 hrs of eating window. I keep calories in check with a healthy balanced diet. My exercise begins after my last hour of fasting, I eat a few fruits (mango and raspberries) and an avocado (topped with a homemade crushed walnut dressing) and I’m good to lift weights and run. My body feels light and healthy. Amazing solution to any fitness junky.

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).

In many Lutheran churches, the Sundays during the Lenten season are called by the first word of their respective Latin Introitus (with the exception of Palm/Passion Sunday): Invocavit, Reminiscere, Oculi, Laetare, and Judica. Many Lutheran church orders of the 16th century retained the observation of the Lenten fast, and Lutherans have observed this season with a serene, earnest attitude. Special days of eucharistic communion were set aside on Maundy Thursday and Good Friday.
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.
Unger’s Bible Dictionary explains that the word fast in the Bible is from the Hebrew word sum, meaning “to cover” the mouth, or from the Greek word nesteuo , meaning “to abstain.” For spiritual purposes, it means to go without eating and drinking (Esther 4:16 Esther 4:16Go, gather together all the Jews that are present in Shushan, and fast you for me, and neither eat nor drink three days, night or day: I also and my maidens will fast likewise; and so will I go in to the king, which is not according to the law: and if I perish, I perish.
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.
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.

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]
