All of these things tend to cause malassimilation, which is the secondary cause of emaciation. In a majority of cases the loss of weight begins while the body is surfeited with food. In fact, it is nothing uncommon for those suffering most from this condition to consume from three to four times the necessary quantity of food; overeating becomes a habit, and consequent fermentation and toxic substances, usually known as autointoxication, are the results. The causes of emaciation, according to most authorities, are impoverished blood and malnutrition. With these opinions the writer fully agrees, but the intelligent reader will naturally inquire--What are the causes of impoverished blood and malnutrition? The answer goes directly back to the food question. [Sidenote: Mental causes of emaciation] All mental influences, business, social, or financial worry, contribute their share toward physical emaciation, but when the body is perfectly nourished it is more capable of withstanding these drains because it is made fearless by perfect health. Behind all forms of business and financial trouble is the demon "fear," and fear rests on the uncertainty of our ability to provide creature comforts and necessities; therefore when we have mastered the science of feeding our bodies, and have learned how simply and cheaply this may be done, the mere possession of such knowledge does more than all else to make of us philosophers and students, eliminating fear and worry of every kind, as in health the mind is usually in a state of optimism and tranquillity. EMACIATION OR UNDERWEIGHT--THE SYMPTOMS The symptoms of emaciation, of course, are so apparent that it is only necessary to say that when the above-named errors are corrected, and the following symptoms are observed, the normal weight can nearly always be maintained. So-called cold-sores, fevered lips and canker-sores on the tongue, intestinal congestion, torpidity of the liver, slight headaches, fullness after eating, alternate constipation and diarrhea, are all symptoms that point to the causes of emaciation. EMACIATION OR UNDERWEIGHT--THE REMEDY Emaciation is sometimes caused by organic or hereditary dis-eases, but the usual causes are to be found within the field of dietetics. The remedy, therefore, is first to naturalize or normalize the diet as to quantity, selection, proportion, and combinations of food. In the majority of cases, those who come to the food scientist for treatment will be those who have tried every conceivable remedy except the natural one, therefore they come in a chronic state of emaciation, poisoned by overeating. Never having been instructed in regard to diet, exercise, breathing, bathing, or any other hygienic law, they will, in most cases, require a counteractive or remedial diet. There may be a number of supplementary causes to be considered, but the most important things for the practitioner to ascertain are: 1 Time the patient rises
