To prevent this, then, we want to apply to our own lives that rule of all temperance, never to let the mind dwell on anything wherein pleasure’s bait is hid; but above all to be specially watchful against the pleasure of taste. For that seems in a way the most deeply rooted, and to be the mother as it were of all forbidden enjoyment. The pleasures of eating and drinking, leading to boundless excess, inflict upon the body the doom of the most dreadful sufferings; for over-indulgence is the parent of most of the painful diseases. To secure for the body a continuous tranquility, unstirred by the pains of surfeit, we must make up our minds to a more sparing regimen, and constitute the need of it on each occasion not the pleasure of it, as the measure and limit of our indulgence. If the sweetness will nevertheless mingle itself with the satisfaction of the need (for hunger knows how to sweeten everything, and by the vehemence of appetite she gives the zest of pleasure to every discoverable supply of the need), we must not because of the resulting enjoyment reject the satisfaction, nor yet make this latter our leading aim. In everything we must select the expedient quantity, and leave untouched what merely feasts the senses.

—Saint Gregory of Nyssa, On Virginity

Their food consisted of only a small amount of bread and salt that they ate after sunset.

Saint John Chrysostom, On the Vanity of Riches

Health and the belly, these are the two idols—especially with men of the present age, of whom I myself, a great sinner, am one—for which we live, and which we continually serve, even to the neglect of the duties of our Christian calling—for instance, to the neglect of the reading of the Word of God, which is sweeter than honey and honey-comb; to the neglect of prayer, that sweetest converse with God, and of the preaching of the Word of God. To walk a great deal for health, and to incite the appetite, to eat with appetite —such are the objects of the desires and aspirations of many of us. But through our frequent walks, through our fondness for food and drink, we shall find that one thing has been neglected, and another irrevocably missed, whilst others have not even entered into our minds; for can the time after a good dinner or supper be really a good time for any serious work! Even if we would like to occupy ourselves with work, the belly, full of food and drink, draws us away from it, and constrains us to rest, so that we begin to slumber over our work. What sort of work can it be? Indeed, there is nothing left, if it is after dinner, but to lie down and rest, and if it is after supper, after having prayed somehow or other (for a satiated man cannot even pray as he should), to go to bed and sleep—the miserable consequence of an overloaded stomach—until the next morning. And in the morning there is another sacrifice to your belly ready in the shape of a dainty breakfast. You get up, pray, of course not with your whole heart—since with our whole heart we can only eat and drink, walk, read novels, go to theatres, dance at evening parties, dress elegantly—and thus you pray, out of habit, carelessly, to save appearances, only as a form, without the essence of the prayer, without lively faith, without power, without any fervour in your petitions, praises, and thanks to the Lord God for His uncountable mercies, and then you hurry again to food and drink.

—St. John of Kronstadt, My Life in Christ

let us hunger here, that we may be filled there

Philoxenus, Ascetic Discourses (1894) pp.403-471. Discourse 11 — On Abstinence

Unto thee then, O disciple, if thou wishest thy discipleship to be good, let the table, which unto others is a place of pleasure, be a place of fighting,

Philoxenus, Ascetic Discourses (1894) pp.403-471. Discourse 11 — On Abstinence

Everything which is laid upon the table for thy food, and which thine eye looketh upon and lusteth after, thou shalt not think of, but say quietly unto thy belly, “Because thou hast lusted therefor thou shalt not taste it;

Philoxenus, Ascetic Discourses (1894) pp.403-471. Discourse 11 — On Abstinence

Observe then, O thou [disciple], very carefully and with discerning knowledge, that not all hunger is the hunger of nature, and that not all meat is the meat which satisfieth want, and observe the different kinds of hunger, and distinguish and select with knowledge thine own hunger from among them. One kind of hunger belongeth to youth, and another ariseth from weakness, and another from excessive emptiness, and another from habit, and another from idleness of the thoughts which have nothing wherewith to occupy themselves, and another from the feebleness of the thoughts, and another from the daily cutting off which happeneth unto the body, and another from the coldness of the body which seeketh to be made warm [p. by meat, and another which excessive labour produceth; these and such like things are the causes of hunger, besides there being some men also whose hunger is not a healthy hunger. Therefore many men are able to bear hunger from the beginning of the day, and some are an hungered at the second hour, and others at the fourth, and others at the sixth, and others at the ninth, and others in the evening, and others can endure the hunger of the close of the day until the vigil of the night, and others continue to fast until the third hour; and when they have arrived at the number of a double vigil their natural hunger hath entirely ceased in them, because the natural heat which is stirred up in the body taketh the place of meat to them. And when from these things thou dost understand the varieties of hunger which are born in thee, thou must distinguish and select from them all the hunger which cometh of thy need, but thou must from time to time restrain even this, in order that the endurance of thy affliction may be the more made manifest, by which thy love unto God is made known. Take heed then that the hunger of lust lead thee not astray and thou imagine it to be the hunger of nature. Now the real hunger of nature is not the want of food in the stomach, but the want of the power of the food in all the members, for when the members have put off the power of food, and have put on in its stead weakness, and although thou callest unto them they respond not with whatever service thou wishest, this is natural hunger; and thou must therefore take carefully such food as will restore the power to the members, being watchful of thy thought that it be not mingled with the body in the meat, and thou must make the lust which is in thee to sleep, lest it be roused up and the lust for food be excited by thee instead of by want; and if this happeneth thy meal is one to be blamed, even though thou takest food because of hunger, and eatest sparingly.
