Most doctors admit that 99% of human beings eat more than is needed. Indeed, this is a fact of everyday experience, and does not require to be proclaimed by any doctor. There is no fear at all of men ruining their health by eating too little; and the great need is for a reduction in the quantity of food that we generally take.
As said above, it is of the utmost importance to masticate the food thoroughly well. By so doing, we shall be able to extract the maximum of nutriment from the minimum of food. Experienced persons point out that the fæces of a man whose food is wholesome, and who does not eat too much, will be small in quantity, quite solid and smooth, dark in colour, and free from all foul smell. The man who does not have such fæces should understand that he has eaten too much of unwholesome food, and has failed to masticate it well. Also, if a man does not get sleep at night, or if his sleep be troubled by dreams, and if his tongue be dirty in the morning, he should know that he has been guilty of excessive eating. And if he has to get up several times at night to make water, it means that he has taken too much liquid food at night. By these and other tests, every man can arrive at the exact quantity of food that is needed for him. Many men suffer from foul breath, which shows that their food has not been well digested. In many cases, again, too much eating gives rise to pimples on the face, and in the nose; and many people suffer from wind in the stomach. The root of all these troubles is, to put it plainly, that we have converted our stomach into a latrine, and we carry this latrine about with us. When we consider the matter in a sober light, we cannot help feeling an unmixed contempt for ourselves. If we want to avoid the sin of over-eating, we should take a vow never to have anything to do with feasts of all kinds. Of course, we should feed those who come to us as guests, but only so as not to violate the laws of health. Do we ever think of inviting our friends to clean their teeth with us, or to take a glass of water? Is not eating as strictly a matter of health as these things? Why, then, should we make so much fuss about it? We have become such gluttons by habit that our tongues are ever craving for abnormal sensations. Hence we think it a sacred duty to cram our guests with rich food, and we cherish the hope that they will do likewise for us, when their turn comes! If, an hour after eating, we ask a clean-bodied friend to smell our mouth, and if he should tell us his exact feelings, we should have to hide our heads in utter shame! But some people are so shameless that they take purgatives soon after eating, that they might be able to eat still more or they even vomit out what they have eaten in order to sit down again to the feast at once!
Since even the best of us are more or less guilty of over-eating, our wise forefathers have prescribed frequent fasts as a religious duty. Indeed, merely from the point of view of health, it will be highly beneficial to fast at least once a fortnight. Many pious Hindus take only one meal a day during the rainy season. This is a practice based upon the soundest hygienic principles. For, when the air is damp and the sky cloudy, the digestive organs are weaker than usual, and hence there should be a reduction in the quantity of food.
And now we will consider how may meals we may take in the day. Numberless people in India are content with only two meals. Those who do hard labour take three meals, but a system of four meals has arisen after the invention of English medicines! Of late, several societies have been formed in England and in America in order to exhort the people to take only two meals a day. They say that we should not take a breakfast early in the morning, since our sleep itself serves the purpose of the breakfast. As soon as we get up in the morning we should prepare to work rather than to eat. We should take our meal only after working for three hours. Those who hold these views take only two meals a day, and do not even take tea in the interval. An experienced doctor by name Deway has written an excellent book on Fasting, in which he has shown the benefits of dispensing with the breakfast. I can also say from my experience that there is absolutely no need to eat more than twice, for a man who has passed the period of youth, and whose body has attained its fullest growth.

EXERCISE
Exercise is as much of a vital necessity for man as air, water and food, in the sense that no man who does not take exercise regularly, can be perfectly healthy. By “exercise” we do not mean merely walking, or games like hockey, football, and cricket; we include under the term all physical and mental activity. Exercise, even as food, is as essential to the mind as to the body. The mind is much weakened by want of exercise as the body, and a feeble mind is, indeed, a form of disease. An athlete, for instance, who is an expert in wrestling, cannot be regarded as a really healthy man, unless his mind is equally efficient. As already explained, “a sound mind in a sound body” alone constitutes true health.
Which, then, are those exercises which keep the body and the mind equally efficient? Indeed, Nature has so arranged it that we can be engaged in physical as well as mental work at the same time. The vast majority of men on earth live by field-labour. The farmer has to do strenuous bodily exercise at any cost, for he has to work for 8 or 10 hours, or sometimes even more, in order to earn his bread and clothing. And efficient labour is impossible unless the mind is also in good condition. He has to attend to all the many details of cultivation; he must have a good knowledge of soils and seasons, and perhaps also of the movements of the sun, the moon, and the stars. Even the ablest men will be beaten by the farmer in these matters. He knows the state of his immediate surroundings thoroughly well, he can find the directions by looking at the stars in the night, and tell a great many things from the ways of birds and beasts. He knows, for instance, that rain is about to fall when a particular class of birds gather together, and begin to make noise. He knows as much of the earth and the sky as is necessary for his work. As he has to bring up his children, he must know something of Dharma Sastra. Since he lives under the broad open sky, he easily realises the greatness of God.
