2. Beverage, far from being suppressed, should be augmented, in order to facilitate stomachal digestion and promote general nutrition, though alcoholic liquids must be inhibited; likewise mineral waters, except, perhaps, for occasional use. Both should be replaced by infusions of coffee or tea, taken as hot as can be drank. Henrich Kisch insists that any method which promises rapid and marked decrease of adipose must, _per se_, be objectionable, even if not positively injurious, since it tends to provoke general troubles of nutrition. He suggests that first the fats and hydrocarbons be reduced as little as possible; that a moderate mixed regimen is required, containing a preponderance of albumen, small quantities of hydrocarbons and gelatinous matters, with but very little fat. Certain fatty meats, however, should be generally interdicted, such as pork sausage, smoked beef tongue, goose breast, smoked ham, fat salmon, and herring in any form. Eggs, however, may be partaken of in moderation, giving preference to the albumen over the yelk. Farinaceous foods, in the main, should be rejected, even bread being allowed only in small quantities, and then preferably in the form of toast. Cheese likewise contains too much fat; and mushrooms are so rich in hydrocarbons that they should be rejected. Condiments, water, vegetable acids (vinegars excepted) may be permitted; especially pernicious is vinegar where there is any tendency to gout or gravel. All fatty beverages--_bouillon_, unskimmed milk, chocolate, or cacao--and all alcoholics, are hurtful; breakfast tea is undoubtedly the best beverage, but, after a little, is advantageously replaced by light white wine diluted with water. Kisch believes in a free and abundant use of water by the obese, especially where there is a tendency to plethora, since this fluid facilitates oxidation as the result of absorption; thus he advocates the inhibition of large quantities of cold water by all, save those presenting evidence of cardiac insufficiency. In short, his regimen is based upon the administration of a large quantity of albumen, like that of Harvey-Banting. E. Munk recommends an almost identical dietary, save that he prefers great moderation in fluids employed as beverage. M. Robin has sought to harmonize the opposing views regarding fluids, and therefore declares obesity arises from two distinct sources: 1. Augmentation of assimilation. 2. Reduced disassimilation. In the former, he insists water must be interdicted, while in the latter it may be allowed _ad libitum_. Again, in order to recognize the exact variety of obesity, he divides his patients into three classes, each recognizable by the volume of urea excreted. In the first there is an increase above normal; in the second the volume of urea is stationary; in the third decreased, increased, or stationary.
