Ample time is thus given to discover what is possible under a diet, and the necessity of continuing the treatment by a fast is fortified by the knowledge thus obtained.
When merely functional disease is in question, the case in treatment is simplicity itself, unless dissipation, excessive nervous expenditure, or serious blood taint, has largely prohibited vital expression. Patients of this class are ordinarily able to care for themselves throughout a fast of average length.
