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.
We are wise to recognize that food was the enticement the devil used to cause Eve and Adam to sin in the Garden of Eden. In Genesis 2 the Lord God told Adam and Eve that they could eat freely of every tree in the garden of Eden, "but of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die" (Gen. 2:17). God did not tell Adam and Eve to refrain from touching a particular animal or smelling a particular flower or swimming in a certain stream. He told them to refrain from taking a particular fruit into their bodies-one type of fruit out of all the many types He had made available to them.
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."

The physiology of fasting has been widely studied and documented by medical science. Beneficial effects such as lowered cholesterol and improved general functioning have been shown. Fasting as a treatment for illness and disease has been studied less, although some studies around the world have shown beneficial results. A 1984 study showed that workers in Taiwan who had severe chemical poisoning had dramatic improvement after a ten-day fast. In Russia and Japan, studies have demonstrated fasting to be an effective treatment for mental illness. Fasting has been featured on the cover of medical journals, although mainstream medicine has generally ignored fasting and detoxification treatments as valid medical procedures.
Whether a regimen calls for two fasting days a week or eating your meals in a smaller "window" of time in the day, all plans share a near-freedom from calorie counting, a big plus for weary food diarists. Once you have planned your fasting-period menu—say, a 500-calorie day of chicken and veggies—you're set. And in your nonfasting periods, you eat normal, healthy meals (even that steak!) without worrying about every bite.

Intermittent fasting is hard in the contemplation, of that there is no doubt. “You go without food for 24 hours?” people would ask, incredulously when we explained what we were doing. “I could never do that.” But once started, it’s a snap. No worries about what and where to eat for one or two out of the three meals per day. It’s a great liberation. Your food expenditures plummet. And you’re not particularly hungry. … Although it’s tough to overcome the idea of going without food, once you begin the regimen, nothing could be easier.”


Those fasting may experience side effects of fatigue, malaise, aches and pains, emotional duress, acne, headaches, allergies, swelling, vomiting, bad breath, and symptoms of colds and flu. These reactions are sometimes called healing crises, which are caused by temporarily increased levels of toxins in the body due to elimination and cleansing. Lower energy levels should be expected during a fast.
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.
Basically, the 12:12 plan is a type of intermittent fasting where you eat for 12 hours of the day and fast for the other 12 hours. This method requires you to limit your daily calorie intake within a 12-hour window (meaning 12 hours eating, 12 hours fasting), rather than eating whenever you want throughout the day. For instance, if you eat your evening meal or dinner at 8 p.m., you should have your breakfast around 8 a.m. the following morning while on this plan. The 12:12 is claimed to be the simplest type of intermittent fasting, especially for beginners who are trying to lose weight or simply want to improve health. Read - Weight loss: All you need to know about the 16:8 diet and 6 tips to burn belly fat using intermittent fasting

All of this may seem hopelessly contradictory. On the one hand, calorie restriction promotes beneficial biological changes that tend to extend life; on the other, there are built in mechanisms that when triggered by chronic calorie restriction can trigger other health problems. These are complex issues, and any extreme measure is likely to cause more problems than it solves.
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.
Often when we slip up on a fast, we can let ourselves feel condemned and defeated. Breaking your fast in NOT a sin. If anything, you’ve proven your humanity, and 2 Corinthians 12:9 states that, “My strength is made perfect in weakness” (NKJV). God’s strength often shows up in our weakest moments. Don’t let a momentary lapse define your fast. We’re not pushing towards our stomach, we’re not even pushing to ourselves, but we are pushing to be closer to God.
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. 

For charismatic Christians fasting is undertaken at what is described as the leading of God. Fasting is done in order to seek a closer intimacy with God, as well as an act of petition. Some take up a regular fast of one or two days each week as a spiritual observance. Members of holiness movements, such as those started by John Wesley and George Whitefield, often practice such regular fasts as part of their regimen.

Still, researchers are exploring whether fasting might help fight cancer, or help cancer patients tolerate chemotherapy. And they’re putting serious thought into whether fasting has a role in treating and preventing diabetes, cardiovascular disease, and multiple sclerosis. But while the animal literature is rich, the literature in humans is promising — though far from conclusive. As this 2017 review of the science found, the studies on fasting to control Type 2 diabetes come to contradictory results, and there’s “minimal data” comparing the effects of fasting to plain old calorie restriction in overweight or obese people with the disease. There were also no studies on fasting and human cancer rates.
Fasting, abstinence from food or drink or both for health, ritualistic, religious, or ethical purposes. The abstention may be complete or partial, lengthy, of short duration, or intermittent. Fasting has been promoted and practiced from antiquity worldwide by physicians, by the founders and followers of many religions, by culturally designated individuals (e.g., hunters or candidates for initiation rites), and by individuals or groups as an expression of protest against what they believe are violations of social, ethical, or political principles.

Fasting or intermittent calorie restriction may affect cancer and tumor development, but are not currently used as a form of treating cancer.[5][6] In 2011, the American Cancer Society recommended that people undergoing chemotherapy increase their intake of protein and calories,[6] but provided evidence that a short-term period of fasting may have benefits during chemotherapy.[5][7] Chronic fasting is not recommended for people with cancer at risk for weight loss or a suppressed immune system.[5]
