Studies show that intermittent fasting accelerates weight loss. In a 2015 review pooling 40 different studies, participants shed on average 10 pounds in a 10-week period.[1] Another study found that obese adults following an “alternate day” intermittent fasting schedule (eating 25 percent of their daily calories on one day, and eating normally the following day) lost up to 13 pounds over 8 weeks.[2]

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.
Although the findings with mice are well established there’s less evidence that time restricted eating works for humans. One human study found significant weight loss when participants fasted for 11 hours overnight compared with control conditions. Another study found a 4.1 percent weight loss resulting from consuming a single meal in the afternoon although self-reported hunger was greater the next morning. Other studies haven’t supported night-time fasting for humans so it’s too early to draw definitive conclusions but you might want to experiment to see if it would work for you. 
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.
If your doctor has told you that you're in danger of developing diabetes, ask him or her if IF is worth a try. This type of eating plan may help your cells become more sensitive to insulin, says Foroutan. The reason: Every time you eat, your body releases the hormone insulin in an attempt to shuttle sugar from your bloodstream into your cells for energy. But people who are prediabetic are insulin resistant, which means the cells in your body don't respond well to insulin and can't take up glucose so your blood sugar levels stay elevated. Going longer between eating may help because it requires your body to pump out insulin less often.
Praise the Lord im still here. Had a little stumble yesterday but the Lord reassured me thats its not by my might nor power but by his spirit and strength. So im more determined to stay committed make the sacrifice and submit. Amen. Im a working person, so I have set times in the morning 12am and 5am(devotion) when I pray. In the evenings I listen to praise and worship and sermons, read my bible or listen to audio bible, visit the blogs. Visit church services-bible study, fasting, Sunday etc, as often as possible to keep focus. At work I keep away from idle jesting and keep my head phone with me to listen to the same as home. I assign some of my casual leave to attend prayer conferences and fasting services that occurs in the day time. I'm willingly to make the sacrifice as I need more of God. In Jesus' Name.Amen
I sometimes hear people say, "I'm giving up chocolate" and they regard this as a type of fasting. I think this is a rather frivolous approach. The first and foremost purpose of a biblical or spiritual fast is to get a breakthrough on a particular matter that one lifts up to the Lord in prayer. A spiritual fast involves our hearts and the way in which we relate to and trust God. It relates to discerning and receiving strength to follow through on what God might reveal to us about circumstances in our lives or a direction we are to take.

The increase in longevity is also clearly associated with a decrease in disease states that would cut your life short, and calorie restriction is associated with a number of health improvements, including reduced visceral fat, reduced inflammation, lower blood pressure, and improved insulin sensitivity,5,6 just to name a few. Earlier research has demonstrated that calorie restriction helps extend the lifespan of animals by improving insulin sensitivity and inhibiting the mTOR pathway.


These types of side effects weren’t more common in CR dieters overall, but several people had to pull out of the study because of safety concerns. Noted side effects of CR are chronic loss of bone density and lean body mass, and excessive weight loss. Some CR dieters have body mass indexes in the teens, which suggest malnutrition and frailty, Longo says.
You’re consuming less food and thus spending less money. Rather than overeating to put on 1 pound of muscle and 4 pounds of fat in a week or two, you’re aiming to eat exactly enough to put on 1 pound of muscle without adding much fat on top of it.  Yeah, it’s a delicate balance, but there’s far less swing involved. You are just slowly, steadily, and consistently building muscle and strength over many months.

In a paper published in 2002 on the pseudo-experiment, Walford and colleagues reported that the Biosphere staff had been in excellent health. Nearly all of them lowered their blood pressure, blood sugar, cholesterol and other health measures. Still, their skeletal appearance was shocking. “They were malnourished, and they didn’t look healthy,” says Eric Ravussin, a metabolic researcher at the Pennington Biomedical Research Center in Baton Rouge, Louisiana.
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]
