re' loss of weight on a fast, Shelton had this to say about soft and hard fat......
"A woman who fasted in the Health School in January and February of 1950 lost twenty-five pounds in the first two weeks. As before indicated, rapid loss of weight in a fast indicates a poor condition of the tissues. It has been repeatedly noticed that fat individuals who are soft and flabby lose more rapidly than those whose fat is firm and solid. As the fast progresses, the rate of loss decreases in fat patients. Skinny patients commonly lose slowly from the beginning, but one whose tissues are in very poor condition may lose very rapidly at the outset". http://www.soilandhealth.org/02/0201hyglibcat/020127shelton.III/020127.ch17.htm
Shelton considered soft flabby fat deposits to be indicative of tissue of poor quality.
