On this page they say:
"Generally, this diet is not viewed as a healthy or sustainable plan. Much of the weight loss is caused by severe reduction in carbohydrate intake, which means that dieters experience mainly water loss. There is also an extreme reduction in caloric intake. Once the three days is over, regaining any lost weight is almost inevitable
"The long term affects of weight loss and being healthy come from gradual weight loss diets. It is better to lose weight slowly and steadily of 1 to 2 pounds a week instead of a few pounds in a short stipulated period of one day or three days or one week. Furthermore, those who lose weight slowly and steadily are those who are more likely to keep the weight off as well."
The only way to lose 40 lbs in a month is with surgery.
