Jackson says: "In uncomplicated cases of total inanition, or on water only, the lungs are usually normal in appearance. The loss in weight of the lungs in such cases is usually relatively less than that in the body as a whole, though sometimes equal to, or even relatively greater than, that of the entire body. In the young, the lungs usually appear more resistant to loss in weight."--Inanition and Malnutrition, p. 361.
That the lungs are greatly benefited by fasting is shown by their recovery from "disease," even tuberculosis, during a period of abstinence. Shorter fasts are usually required in lung "diseases," than in "disease" of other organs and Carrington thinks this is due to the fact that lung tissue "possesses the inherent power of healing itself in a far shorter time, and more effectually, than any other organ which may be diseased."
