There’s no set schedule for intermittent fasting, but most people do one of three major IF types: the 16:8 diet, the 5:2 diet, or the 24-hour fast. The 16:8 diet allows you to eat during eight ...

5:2 intermittent fasting: This form of intermittent fasting is when someone consumes 25% of their calorie needs—typically 500 for women and 600 for men—two days per week. The other days of the ...
The concept of "protein-sparing modified fast" (PSMF) was described by George Blackburn in the early 1970s as an intensive weight-loss diet designed to mitigate the harms associated with protein-calorie malnutrition [8] and nitrogen losses induced by either acute illness or hypocaloric diets in patients with obesity, in order to adapt the patient's metabolism sufficiently to use endogenous fat ...
There is limited evidence that intermittent fasting produces weight loss comparable to a calorie-restricted diet. [5] [6] [33] [34] Most studies on intermittent fasting in humans have observed weight loss, ranging from 2.5% to 9.9%. [35] [36] The reductions in body weight can be attributed to the loss of fat mass and some lean mass.
A high protein diet relative to a low-fat or high-carbohydrate diet may increase thermogenesis and decrease appetite leading to weight reduction, [53] particularly 3-6 months into a diet when rapid weight loss is observed. [54] However, these advantages may be reduced later at 12–24 months into a diet during the slow weight loss phase. [54]

Typical observed weight loss under prolonged fasting averages at 0.9 kg per day during the first week and 0.3 kg per day by the third week. [14] In early fasting, during periods of high gluconeogenesis, roughly two-thirds of weight lost is lean muscle mass as opposed to fat.
