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.
Improves cholesterol: Intermittent fasting diets impact cholesterol by decreasing your levels of LDL and VLDL cholesterols (the bad stuff). While improving your cholesterol won’t directly lead to weight loss, overweight and obese people are more likely to have dangerously high LDL and VLDL cholesterol, and the cardiovascular risk that comes with it.[8]
Longer fasts likewise can take the form of abstinence from food or some other sacrifice. Some good options for a non-food fast would be abstaining from watching TV from Monday to Friday, reading a biography of a great man or woman of God each week, or dedicating every evening for a week to praying with friends...A longer water-only fast might last from one to three days. If you are fasting from something other than food, your longer fast might last a week. Some use Lent as a time for a longer fast. 
God uses fasting as a teaching tool on one of the annual holy days He commands us to keep. In Leviticus 23:27 God says “afflict your souls” on the Day of Atonement. The New Unger’s Bible Dictionary points out that afflicting your souls is a reference to fasting. So on this particular holy day God commands that His people forgo both food and water for 24 hours as a means of humbling themselves before Him, seeking Him and His will and guidance in life.
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.
You’ll spike your blood sugar when you eat. If you’re fasting on a high-carb diet and you’ve powered through the cravings and lack of energy from low blood sugar, there’s a good chance you’ll eat a ton of carbs when you feast. You want to eat big meals when you fast to make sure you’re getting enough calories, but all those excess carbs in one go will spike your blood sugar in the opposite direction, from low to high.[14] High blood sugar causes fatigue and lack of focus. That raging hunger will also cause you to binge unnecessarily, and whatever carbs you don’t use will get stored as fat.

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]
Social Media Fast: This is becoming one of the more common fasts in our culture. Do you need to take some time away from the noise and refresh? Log out of your accounts, delete them from your device for a period of time, and just spend that time being present with God. Pray and listen. Spend some time in nature soaking in His beauty. Spend some time alone worshipping God.
When I started intermittent fasting, I spent a lot of time thinking about how I wasn’t eating. I would think about how hungry I was, and then, when it came time to break my fast, I would eat more than a regular dinner, thinking I deserved it after having fasted all day. This is how people fail at intermittent fasting. It took me about two weeks to figure it out.

It may sound really hard at first, but at least eight hours of the 16 is spent sleeping. There's also a lot of downtime between dinner and sleeping that adds up. Just be patient with yourself, and you'll find your body adjusting to this new eating schedule in no time. If you're looking to get started now, what better way than planning what you're going to eat during your eight-hour eating window?

Improves cholesterol: Intermittent fasting diets impact cholesterol by decreasing your levels of LDL and VLDL cholesterols (the bad stuff). While improving your cholesterol won’t directly lead to weight loss, overweight and obese people are more likely to have dangerously high LDL and VLDL cholesterol, and the cardiovascular risk that comes with it.[8]
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].
You can still get great benefits while sneaking in a cup of coffee however if you want optimal results nothing should enter your stomach other than water while fasting. Not even meds. One of the reasons that the intermittent fasting is so effective is that the enzymes in your gut are allowed to rest. Your 8 hour window should start as soon as anything other than water is ingested which includes coffee. Again, that is the strict answer but you can certainly still get good benefits even if you have your coffee during your fast

American King James Version×). Isaiah 58 gives both bad and good examples of fasting, contrasting wrong attitudes and actions (Isaiah 58:3-5 Isaiah 58:3-5 3 Why have we fasted, say they, and you see not? why have we afflicted our soul, and you take no knowledge? Behold, in the day of your fast you find pleasure, and exact all your labors. 4 Behold, you fast for strife and debate, and to smite with the fist of wickedness: you shall not fast as you do this day, to make your voice to be heard on high. 5 Is it such a fast that I have chosen? a day for a man to afflict his soul? is it to bow down his head as a bulrush, and to spread sackcloth and ashes under him? will you call this a fast, and an acceptable day to the LORD?
Yes, you'll be hungry at times—but it's not necessarily overwhelming or constant. "Hunger doesn't seem to get worse as the day goes on, and some of our studies report increased fullness and satisfaction," says Kristin Hoddy, Ph.D., R.D.N., a dietitian in private practice who has researched fasting. "Some subjects remarked that they'd get distracted and 'forget' they were hungry."
In more recent years, many churches affected by liturgical renewal movements have begun to encourage fasting as part of Lent and sometimes Advent, two penitential seasons of the liturgical year. Members of the Anabaptist movement generally fast in private. The practice is not regulated by ecclesiastic authority.[74] Some other Protestants consider fasting, usually accompanied by prayer, to be an important part of their personal spiritual experience, apart from any liturgical tradition.
How can you know if you are praying and fasting according to God's will? Are you praying and fasting for things that honor and glorify God? Does the Bible clearly reveal that it is God's will for you? If we are asking for something that is not honoring to God or not God's will for our lives, God will not give what we ask for, whether we fast or not. How can we know God's will? God promises to give us wisdom when we ask. James 1:5 tells us, "If any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given to him."
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.
When you don’t eat any food for a set period of time each day, you do your body and your brain a whole lot of good. It makes sense from an evolutionary standpoint. For most of history, people weren’t eating three square meals a day, plus grazing on snacks. Instead, humans evolved in situations where there wasn’t much food, and they learned to thrive when fasting.[1] Nowadays, we don’t have to hunt for food (although hunting for your own meat isn’t a bad idea!). Rather, we spend most of our days in front of computers, and we eat whenever we want — even though our bodies aren’t adapted to this behavior.
If the better part of wisdom for you, in your health condition, is not to go without food, consider fasting from television, computer, social media, or some other regular enjoyment that would bend your heart toward greater enjoyment of Jesus. Paul even talks about married couples fasting from sex “for a limited time, that you may devote yourselves to prayer” (1 Corinthians 7:5).
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.
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.
Dietrich Bonhoeffer, in his book The Cost of Discipleship, said, “Jesus takes it for granted that His disciples will observe the pious custom of fasting. Strict exercise of self-control is an essential feature of the Christian life. Such customs have only one purpose — to make the disciples more ready and cheerful to accomplish those things which God would have done.”

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.


When it comes to intermittent fasting, there’s no one-size-fits-all. Bulletproof Intermittent Fasting fits all your eating into a 6-hour window, leaving you with an 18-hour-fast each day. This is often called “18:6” fasting. You can also try variations such as the one-meal-a-day method, or fasting every other day. The key is to experiment and listen to your body to see what works best for you. If intermittent fasting causes fatigue or other negative symptoms, try fasting just once or twice a week, and build up from there.

Intermittent fasting, unlike many other diets, is famously flexible in that you choose the days and hours during which you think it’s best to fast. The two most common methods are the 16:8 strategy—where you eat whatever you want (within reason) for eight hours a day and then fast for the other 16—and the 5:2 method, where you eat normally five days a week and then keep your food intake to roughly 500-600 calories for the other two days. It’s kind of a simplified-calories math problem that’s supposed to prevent the yo-yo effect of weight loss and weight gain.
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.
In order for a fast for God to be effective, you must also pray. Praying and fasting to God is a powerful weapon against adversity. Joel 1:14 says, "Declare a holy fast; call a sacred assembly. Summon the elders and all who live in the land to the house of the Lord your God, and cry out to the Lord." A fast for God puts your trust in Him as the only one who can help you. During your fast for God, remember that He is faithful and true, willing and able to help you in any way He can.
Autophagy is spring cleaning for your cells. It’s Latin for “self-eating,” which is spot-on: when autophagy turns on, your cells sift through their internal parts, get rid of anything that’s damaged or old, and install shiny new versions.[8] Autophagy is like a tune-up for your car: afterward everything runs more smoothly. It reduces inflammation and even boosts longevity. Intermittent fasting triggers, to quote researchers, “profound” autophagy, especially in your brain.[9]
Eve listened to what the devil had to say to her about the benefits of eating what God had prohibited. The devil always points out the would-be and usually short-term benefits of sin. Many substances that are ultimately harmful for us taste good or feel good or bring pleasure. In some cases, the partaking of the substance makes us feel like adults, feel accepted by others, or feel more powerful and in greater control. Some people say about certain foods and substances that they "give me quick energy," "make me more alert," or "help me relax."

I take a 1200 calorie diet and I exercise. A lot. In the morning I have a cup of coffee and do a 1:30hr workout consisting of 2 HIIT workouts and a strength workout along with A 20 minute fat burning yoga. I open my fast at 2pm and stop eating at 8pm after 3 hours before sleeping I do another 1 hr workout. One HIIT workout and some cardio. Then I go to sleep. Acc to my calorie calculator I burn around 600-800 calories. I try my best to eat as healthy as possible but I’m seeing no results. I tried following all the advices I could find but I don’t understand what’s wrong. People are losing this much weight in a week. It’s very disheartening for me.
WHAT DO YOU THINK? - We have all sinned and deserve God's judgment. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him. Jesus, the creator and eternal Son of God, who lived a sinless life, loves us so much that He died for our sins, taking the punishment that we deserve, was buried, and rose from the dead according to the Bible. If you truly believe and trust this in your heart, receiving Jesus alone as your Savior, declaring, "Jesus is Lord," you will be saved from judgment and spend eternity with God in heaven.
Although I do not fast like you do (from sunrise to sunset) I do continue to fast not just to maintain my weight but to free the mind and body or the extra weight and burdens that it must carry. You see when your stomach is not full and your mind is not sluggish from trying to digest a heavy meal you start to have more energy think clearer, sleep better and feel better. When you can have this in your life for free why not take it. Some people spend thousands to have access to these feelings when we can experience a little bit of this each week.
God had given Adam and Eve authority over all things that He had created-every bird, fish, beast of the field, and over "every herb bearing seed, which is upon the face of all the earth, and every tree, in which is the fruit of a tree yielding seed; to you it shall be for meat" (Gen. 1:29). God did not prohibit Adam and Eve from interacting with any part of God's creation when He commanded them to be fruitful, multiply, replenish the earth, and subdue it-except for this one tree and its fruit. They were not to eat of a particular tree,what God described to them as the "tree of the knowledge of good and evil."
César Chávez undertook a number of spiritual fasts, including a 25-day fast in 1968 promoting the principle of nonviolence, and a fast of 'thanksgiving and hope' to prepare for pre-arranged civil disobedience by farm workers.[17][19] Chávez regarded a spiritual fast as "a personal spiritual transformation".[20] Other progressive campaigns have adopted the tactic.[21]
