Simply put, the calorie gap is that your basic metabolism and various sports consume 3000 calories a day, and your diet intake is 2600 calories that day, then you have a calorie gap of 400 calories, which will consume your fat or muscle. For most people, don't set the calorie gap too high when losing weight, because losing weight will have a series of "sequelae". Regarding the formulation of the calorie gap, it is best to ask the nutritionist in detail. After filming Wrestling, amirkhan reduced his body fat from 32% (as if he remembered) to about 9.6 in five months, with a calorie gap of 500 calories per day, but he hired a dietitian in the United States.
