The ordinary person will probably find his appetite leaning towards the simplest of foods, and away from frequency of indulgence. If the breakfast is postponed until a real, earned appetite has been secured, the mid-day or later breakfast (remember always that breakfast means the first meal of the day, no matter when taken) will be so enjoyable a meal, and the appetite will be so entirely satisfied that there will be no more demand for food until evening, and possibly not even then. HOW MANY MEALS A DAY? I am often asked if it is true that I eat only two meals a day; that I never eat breakfast, and why I have dropped that meal. I have two meals a day more habitually than any other number, but not with any prescribed regularity, for the reason that my activities are most irregular at times, and my appetite accommodates itself to my needs. When I am doing work under the most favourable of conditions, one meal a day is the rhythm best appreciated by my body. But the question of "How many meals a day?" is tantamount to the inquiry as to the amount of sleep needed: it is a matter of satisfaction of the natural requirements. The harder one works, the faster one runs, etc., the more air he needs. The same applies to the need for food according to the amount of heat eliminated, and the repair material consumed. The really hardest work that anybody does is done within the body. Muscular effort in normal conditions is not so waste-provoking and exacting as getting rid of excess of food and the counteraction of worry or anger. Likewise, idleness begets uneasiness, uneasiness begets desire for something (nobody knows just what), and groping around for "Don't know what" causes the temptation to eat and drink something which the body does not need; and then the really hard work of the body begins in the attempt of Nature to get rid of the excess. Excess of water can be thrown off in perspiration with comparative ease, but with excess of food it is different. The kidneys, bacteria and fuel furnaces of the body are all over-worked to get rid of it. When I am so busy that I have only time to replenish the real exhausted need of the body, say half an hour at most, I find one meal a day all that my appetite demands of me. This is taken after I have done my day's work of, say, eight hours of writing, or twelve or thirteen hours of bicycle riding or mountain climbing, and then I do not have appetite for more until the next day, after the work is done. When I mention two meals as being the more habitual, it is because I am not fully, constructively active all the time now, although I am usually "snowed under" with things that I _might_ do to advantage; and hence I conform to the social custom and sit down to table some time in the evening to be social.
