Depending on dominance in a diet of these or those feedstuffs P. of subdivide on proteinaceous, carbohydrate, fatty (are applied seldom) and combined. Fasting days treat as well the modes of a complete starvation (see. Starvation , medical), so-called water days. Rubles of appoint for the purpose of stimulation of exchange processes, removal from an organism of nedookislenny products of interstitial exchange and excesses of sodium, increase in a diuresis. Rubles of appoint against the background of the main medical diet (see. clinical nutrition ) 1 — 3 time a week. The number of meals in such days — 4 — 6 times. Depending on indications, the nature of a disease of the patient and individual portability they can alternate and be dual or stroyenny.

Carbohydrate fasting days

Are used by hl. obr. the complex carbohydrates (see) which are contained in vegetables and fruit. Their efficiency is caused by the small caloric content, influence of salts of potassium on increase in a diuresis, increase in a tone of vessels, metabolism of a myocardium and a liver, and also alkalization of urine and removal of oxalate and urate salts. Also other vegetable R. is most widely used apple, kuragovy (potassium), rice kompotny, potato.

Appoint apple R. at obesity, a hypertension, atherosclerosis, hron, nephrite, gout, urate diathesis, hron, a coloenteritis. The patient in 5 receptions receives 1,2 — 1,5 kg of crude or baked apples.
