The diet or regimen is the next point of consideration, and it is very simple. As the intention of the trainer is to preserve the strength of the pedestrian, he must take care to keep him in good condition by nourishing food. Animal diet is alone prescribed, and beef and mutton are preferred. The lean of fat beef cooked in steaks, with very little salt, is the best, and it should be rather under-done than otherwise. Mutton being reckoned easy of digestion, may be occasionally given, to vary the diet, and gratify the taste. The legs of fowls are highly esteemed. It is preferable to have the meat BROILED, as much of its nutritive qualities is lost by roasting or boiling[28]. Biscuit and stale bread are the only preparations of vegetable matter which are permitted to be given; and every thing inducing flatulency must be carefully avoided. Veal and lamb are never allowed, nor pork, which operates as a laxative on some people; and all fat or greasy substances are prohibited, as they induce bile, and consequently injure the stomach. But it has been proved by experience, that the lean of meat contains more nourishment than the fat, and in every case, the most substantial food is preferable to any other kind. Vegetables, such as turnips, carrots, or potatoes, are never given, as they are watery, and of difficult digestion. On the same principle, fish must be avoided, and besides, they are not sufficiently nutritious. Neither butter nor cheese is allowed; the one being very indigestible, and the other apt to turn rancid on the stomach. Eggs are also forbidden, excepting the yolk taken raw in the morning. And it must be remarked, that salt, spiceries, and all kinds of seasonings, with the exception of vinegar, are prohibited. With respect to liquors, they must be always taken cold; and home-brewed beer, old, but not bottled, is the best. A little red wine, however, may be given to those who are not fond of malt liquor; but never more than half a pint after dinner. Too much liquor swells the abdomen, and of course injures the breath. The quantity of beer, therefore, should not exceed three pints during the whole day, and it must be taken with breakfast and dinner, no supper being allowed. Water is never given alone, and ardent spirits are strictly prohibited, however diluted. It is an established rule to avoid liquids as much as possible, and no more liquor of any kind is allowed to be taken than what is merely requisite to quench the thirst. Milk is never allowed, as it curdles on the stomach. Soups are not used[29]; nor is any thing liquid taken warm, but gruel or broth, to promote the operation of the physic; and the sweating liquor mentioned above. The broth must be cooled in order to take off the fat, when it may be again warmed; or beef tea may be used in the same manner, with little or no salt. In the days between the purges, the pedestrian must be fed as usual, strictly adhering to the nourishing diet by which he is invigorated.
