What would be the best way for business people to adopt Fletcherism? is often asked. The case is frequently cited to me of a young man or woman who isn't hungry for breakfast at seven o'clock, does not eat at that time because the appetite doesn't demand it; and then gets ravenously hungry at eleven o'clock. It may be impossible to get any food until one-thirty - by which time the feeling comes that one has "waited too long,"and a headache and no desire for food are the results. Or, the case of working-girls who live in boarding-houses, eat no breakfast, and at noon cannot afford the wholesome and hearty food Nature would then crave. Later, at dinner, they have to eat what is put before them, whether they want it or not, or else go without. Will a hearty luncheon, rightly eaten, interfere with a good afternoon's work? I am reminded also that leisure, money, and easily-accessible cafes are not always available for business women.
My answer to such questions is: - Any change of habit is apt to excite a protest on behalf of the body, especially when the body is not properly nourished, and is in a state of more or less disease. When the habit-hunger comes on a few sips of water will quiet the discomfort for the time being and, very likely, until it is convenient to take food comfortably and with the calm and relish necessary to good digestion. Headache, faintness, "all-goneness" and like discomforts, are symptoms, not of hunger, but of the reverse - that is, fermentation of undigested excess of food which the body cannot use.
A person, thus troubled, should brave discomfort for a week, and even go without food entirely for a few meals, in order to give the body a chance to "clean house": then the real sensation of hunger will be expressed by "watering of the mouth" and a keen desire for some simple food such as bread and butter, or dry bread alone. But this healthy appetite will "keep" and accumlate until it is convenient to take food.
