Pounds & Inches: Massage 
I never allow any kind of massage during treatment. It is entirely unnecessary and merely disturbs a very delicate process which is going on in the tissues. Few indeed are the masseurs and masseuses who can resist the temptation to knead and hammer abnormal fat deposits. In the course of rapid reduction it is sometimes possible to pick up a fold of skin which has not yet had time to adjust itself, as it always does under HCG, to the changed figure. This fold contains its normal subcutaneous fat and may be almost an inch thick. It is one of the main objects of the HCG treatment to keep that fat there. Patients and their masseurs do not always understand this and give this fat a working-over. I have seen such patients who were as black and blue as if they had received a sound thrashing.
In my opinion, massage, thumping, rolling, kneading, and shivering undertaken for the purpose of reducing abnormal fat can do nothing but harm. We once had the honor of treating the proprietress of a high class institution that specialized in such antics. She had the audacity to confess that she was taking our treatment to convince her clients of the efficacy of her methods, which she had found useless in her own case.
How anyone in his right mind is able to believe that fatty tissue can be shifted mechanically or be made to vanish by squeezing is beyond my comprehension. The only effect obtained is severe bruising. The torn tissue then forms scars, and these slowly contract making the fatty tissue even harder and more unyielding.
A lady once consulted us for her most ungainly legs. Large masses of fat bulged over the ankles of her tiny feet, and there were about 40 lbs. too much on her hips and thighs. We assured her that this overweight could be lost and that her ankles would markedly improve in the process. Her treatment progressed most satisfactorily but to our surprise there was no improvement in her ankles. We then discovered that she had for years been taking every kind of mechanical, electric and heat treatment for her legs and that she had made up her mind to resort to plastic surgery if we failed.
Re-examining the fat above her ankles, we found that it was unusually hard. We attributed this to the countless minor injuries inflicted by kneading. These injuries had healed but had left a tough network of connective scar-tissue in which the fat was imprisoned. Ready to try anything, she was put to bed for the remaining three weeks of her first course with her lower legs tightly strapped in unyielding bandages. Every day the pressure was increased. The combination of HCG, diet and strapping brought about a marked improvement in the shape of her ankles. At the end of her first course she returned to her home abroad. Three months later she came back for her second course. She had maintained both her weight and the improvement of her ankles. The same procedure was repeated, and after five weeks she left the hospital with a normal weight and legs that, if not exactly shapely, were at least unobtrusive. Where no such injuries of the tissues have been inflicted by inappropriate methods of treatment, these drastic measures are never necessary.
