But what is enough? That in regard to the feeding is a very serious question. At the first glance, too, it seems to be one which is not altogether easy to answer, because some men require more food than others, just as some steam engines consume more coal than others, to keep themselves moving; and just as some lamps take more oil than others, to keep up their flames. It is, nevertheless, a question which may be very easily answered. Every man who eats his meal slowly and deliberately,—not forgetting the mill,—has had enough when his appetite is satisfied. Appetite really is Nature’s own guard. It is ruled, not by the state of the stomach, but by the condition of the blood. When so much blood has been taken from the supply-pipes of your body, by the working parts, that those pipes begin to be comparatively empty, their emptiness makes itself felt in your frame as hunger. Obedient to the hint, you find up food and eat. But while you are eating what happens? First you seize the food with all the keen relish of a hungry man. Then as you eat on, the relish becomes less and less, and if your meal be a simple one, when you have had enough, all relish has disappeared, and the very things that tasted so deliciously at first, are insipid, so that you find no farther enjoyment in the act of grinding and swallowing them. Go on eating after this, and the insipidity will be transformed into disgust; and if notwithstanding this you still persevere in forcing food into your stomach, that sensible organ will at last rebel against the tyranny, and return the whole which it has received upon your hands. Then it will be some little time before the stomach gets over the insult. Consequently the blood remains all this while in the impoverished state, and the result of the over-gorge is that the body itself is actually starved, instead of being feasted. If when your natural appetite for food is satisfied, and your enjoyment and relish of it have ceased, you have rich and high flavored dishes set before you, the high-flavors will then still prove agreeable to the palate, and act upon it as a sort of excitement, and the natural appetite will have its work superseded by a false and artificial one, and you will go on eating under this temptation, until your stomach is over-crammed. All the so-called luxuries of cooking are merely devices to make men eat more, who have already eaten enough.
