All of our care of the faster should be designed to conserve in every possible manner, his energies and reserves. Every method of care and every influence in the environment of the patient that occasions a dissipation of the patient's energies and reserves should be carefully avoided. Much harm results from the use of drugs and measures of treatment that are not conservative and there is everywhere, in the ranks of those who oppose fasting, a tendency to credit this harm to the fast, rather than to the enervating measures employed in mis-caring for the patient. Let conservation, rather than dissipation, be our watch-word. The instructions that follow, if carried out conscientiously, will prove conservative; hence, they will definitely shorten the period of time the patient will have to fast, and will leave him in better physical condition at the end of his fast.
