In this note I propose to do little more than record a few instances, out of many, of persons who have lived for longer or shorter periods, and continue to live, on one meal a day, and let my readers draw their own inferences, merely remarking that these cases have a very great significance as bearing upon the question of the _quantity of food_ best suited to nourish the body and promote health. Dr. Abernethy, a celebrated English physician, affirmed that “one-fourth of all a man eats sustains him; the balance he retains at his risk”; but his countrymen eat four meals, at least. The case of Mrs. Solberg, an emaciated dyspeptic, whose restoration to health was accomplished by the one-meal vegetarian diet and “a change of air” (at home), is mentioned in the chapter on Malaria. S. N. Silver,[64] of Auburn, Me., a hard-working mechanic, has, for upwards of three years, lived on the one-meal-a-day plan. He eats at night, after resting sufficiently from his day’s work. He never eats more than seven meals per week, not even so much as an apple between meals; and on Sundays, unless he takes considerable exercise, his “meal” consists of fruit only——three or four apples, for example. He is a typically healthy young man, and has not in three years experienced a moment of physical inconvenience. He is a vegetarian, and lives wholly on simple, pure food, chiefly bread and fruit. [Footnote 64: Mr. Silver is 30 years old and is 6 feet, 2 inches in height. On the three-meal system his greatest weight was 137 pounds. For two years past, on the new plan, he has weighed from 150 to 160 pounds, according to his work. When he works hard he eats more, and gains in weight; when his work is light he eats light and his weight falls off correspondingly. This illustrates a truly physiological diet. It should always be thus with man and the domestic animals alike. In practice, however, the reverse is the rule: the weight increases during leisure and decreases when hard work is done. Both our athletes and race-horses are permitted to fatten between times, and are fitted for sharp work by reducing their weight by exercise. In other words, they are allowed to become diseased, and then they are “cured.” This process is apt to result, finally, in premature death, or at least so exhausts the vital forces as to render former accomplishments impossible, at an age when the individual should be in his prime.]
