For persons with cardiovascular diseases, obesity, osteochondrosis it is useful to be on juice-fruit-vegetable diet.

For persons with diseases of digestive system, bronchial asthma, skin allergies use of sparing hypoallergenic diet is recommended. In case of medical fasting under outpatients’ conditions use of an adopted variant of re-feeding diet is possible. The main principals of re-feeding are fractional food intake, gradual broadening of a diet, exclusion of salt. As usual, after a small portion of food intake patients feel satiation very quickly, that is why it is recommended to take food by small portions every 2-3 hours. In case of overeating at this period a syndrome of "food overloading " can be observed. Sickness, vomiting, unpleasant feeling in epi- and mesogastria can be noticed. In this case lavage of the stomach along with laxative is necessary. In case of spontaneous "food overloading" patients are recommended to abstain from any food during one day. After that the rehabilitating nutrition continues according to the usual scheme.

According to the clinical experience the are 3 main periods can be distinguished in the re-feeding period:

1st stage (asthenia period) lasts first 2-4 days

The following symptoms are common: weakness, emotional instability, and quick fatigability. Sometimes a feeling of discomfort or ache in epigastria appears, due to aggravation of motorics intestine. The symptoms of cardiac arrhythmia (extrasistology) are noticed rarer. During this 1st stage of re-feeding the organism move from endogenic nutrition to normal ecsogenic nutrition and such metabolic transition can be difficult for the organism. That is why patients are prescribed ward regimen or confinement to bed, all physiotherapeutic treatments, massage, gymnastics and cleaning enemas should be called off. Depending on the type of the diet fruit or vegetable juice (apple, pears, peach etc) diluted in two with water should be prescribed, or rice or wheat water and gruel on water without salt and sugar (buckwheat porridge, rice and millet porridge). The body mass of the patients during this 1st stage of re-feeding continues to decrease. On the third-forth day of re-feeding, independent stool appears, otherwise a cleaning enema should be prescribed.

2nd stage (intensive rehabilitation)

The length of this stage depends on the length of fasting period (usually it is a 1/2 of fasting period). Patients notice improvement of general feeling, appetite appears, the mass of the body increases. All blood biochemistry is normalizing and acetone disappears in the urine. The exercises must be implemented (walks, gymnastics). From the 5-7th day patients have buckwheat, millet, oatmeal porridge on milk, vegetable puree, bread, butter, kefir, curds, nuts, honey. All hard little part of food should be thoroughly chewed. The intake of meat, fish, eggs and mushrooms as well as salt are not recommended. At this stage rarely under skin edema is observed, first of all under eyes. This occurs due to use of common salt or products with it’s high content (herring, brown bread, cheese, carnichons, etc). It is recommended to keep to achlorid diet, to use diuretics (decoction of leaves of bearberry, fruits of juniper, leaves of red bilberry, birch, etc)

3d stage (normalization)

Is characterized by restoration of all physiological functions, stabilization of mass of the body, transition to normal nutrition.

The length of re-feeding period is equal to the length of fasting period.
