Christian fasting is more than denying ourselves food or something else of the flesh - it's a sacrificial lifestyle before God. In Isaiah 58, we learn what a "true fast" is. It's not just a one-time act of humility and denial before God, it's a lifestyle of servant ministry to others. As Isaiah tells us, fasting encourages humility, loosens the chains of injustice, unties the chords of the yoke, frees the oppressed, feeds the hungry, provides for the poor, and clothes the naked. This concept of fasting isn't a one day thing - it's a lifestyle of servant living for God and others.
No-one promoting this fasting diet plan should tell you to not eat anything for two days a week. If the body doesn’t get enough nutrients, it starts building a more durable fat, which is made for long-term safety and is harder to lose. Not eating for two days on a regular basis will build this type of fat and will make it hard to slim down if that is what you desire.

The so-called black fast refers to a day or days of penance on which only one meal is allowed, and that in the evening. The prescription of this type of fast not only forbids the partaking of meats but also of all dairy products, such as eggs, butter, cheese and milk. Wine and other alcoholic beverages are forbidden as well. In short, only bread, water and vegetables form part of the diet for one following such a fast.

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.  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:
“There’s really no conclusive evidence that there’s any benefit,” Sasson says. The German Cancer Research Center study qualified its findings by noting that the positive results weren’t noticeably better than those experienced by subjects who adopted a conventional calorie-reduction diet. In other words, it works, but not notably better than the alternative. (Sasson also offered a helpful list of individuals who should not give intermittent fasting a try: pregnant women and anyone with diabetes, cancer, or an eating disorder.)

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.
Fasting is always practiced prior to surgery or other procedures that require general anesthesia because of the risk of pulmonary aspiration of gastric contents after induction of anesthesia (i.e., vomiting and inhaling the vomit, causing life-threatening aspiration pneumonia). Additionally, certain medical tests, such as cholesterol testing (lipid panel) or certain blood glucose measurements require fasting for several hours so that a baseline can be established. In the case of a lipid panel, failure to fast for a full 12 hours (including vitamins) will guarantee an elevated triglyceride measurement.
