Patients who need to lose 15 pounds (7 kg.) or less require 26 days treatment with 23 daily injections. The extra three days are needed because all patients must continue the 500-Calorie diet for three days after the last injection. This is a very essential part of the treatment, because if they start eating normally as long as there is even a trace of HCG in their body they put on weight alarmingly at the end of the treatment. After three days when all the HCG has been eliminated this does not happen, because the blood is then no longer saturated with food and can thus accommodate an extra influx from the intestines without increasing its volume by retaining water.
We never give a treatment lasting less than 26 days, even in patients needing to lose only 5 pounds. It seems that even in the mildest cases of obesity the diencephalon requires about three weeks rest from the maximal exertion to which it has been previously subjected in order to regain fully its normal fat-banking capacity. Clinically this expresses itself, in the fact that, when in these mild cases, treatment is stopped as soon as the weight is normal, which may be achieved in a week, it is much more easily regained than after a full course of 23 injections.
As soon as such patients have lost all their abnormal superfluous fat, they at once begin to feel ravenously hungry in spite of continued injections. This is because HCG only puts abnormal fat into circulation and cannot, in the doses used, liberate normal fat deposits; indeed, it seems to prevent their consumption. As soon as their statistically normal weight is reached, these patients are put on 800-1000 Calories for the rest of the treatment.
The diet is arranged in such a way that the weight remains perfectly stationary and is thus continued for three days after the 23rd injection. Only then are the patients free to eat anything they please except sugar and starches for the next three weeks.
Such early cases are common among actresses, models, and persons who are tired of obesity, having seen its ravages in other members of their family. Film actresses frequently explain that they must weigh less than normal. With this request we flatly refuse to comply, first, because we undertake to cure a disorder, not to create a new one, and second, because it is in the nature of the HCG method that it is self limiting. It becomes completely ineffective as soon as all abnormal fat is consumed. Actresses with a slight tendency to obesity, having tried all manner of reducing methods, invariably come to the conclusion that their figure is satisfactory only when they are underweight, simply because none of these methods remove their superfluous fat deposits. When they see that under HCG their figure improves out of all proportion to the amount of weight lost, they are nearly always content to remain within their normal weight-range.
When a patient has more than 15 pounds to lose the treatment takes longer but the maximum we give in a single course is 40 injections, nor do we as a rule allow patients to lose more than 34 lbs. (15 Kg.) at a time. The treatment is stopped when either 34 lbs. have been lost or 40 injections have been given. The only exception we make is in the case of grotesquely obese patients who may be allowed to lose an additional 5-6 lbs. if this occurs before the 40 injections are up.
