The amount of weight lost on a fast depends on the individual. On a strict seven-day water fast, a person can lose two pounds a day if she is morbidly obese. A person considered mildly to moderately obese can lose one-half to one pound per day. In the first few days, only water weight is lost and not much fat. For this reason, most dieticians warn against quick fixes and suggest eating healthy foods long-term. Anyone 40 to 100 percent above her ideal weight is moderately obese; 100 percent and above is morbid obesity.

8-4-2017 "Fast" is a religious term for a ceremony which may or may not involve a special diet for some period of time. People who don't know anything assume that it only means going without food. Even worse, a lot of people assume that fat is directly related to food intake, and that you can lose weight by not eating. You really ought to study some books about nutrition so you know a few things. Example: Fat is made of carbon and hydrogen. The only way it comes out of the body is if it is turned into carbon dioxide and water and then it comes out through the lungs. So that involves a lot of heavy breathing, and that means jogging or aerobic dancing. Figure on losing one pound per week when you are doing things right.
