If to the moment of passage to Protasov's diet you fed "as all people" - with a small quantity of fresh vegetables and fruits and a large quantity of "poor" carbohydrates and products of industrial production in the ration - that in the first 2 weeks of correct nourishment the unpleasant side effect is possible: the abdominal distension. Do not hurry to follow the majority of doctors and to blame fresh vegetables and fruits in this phenomenon. They are not guilty, but that "rubbish", which remained in the bowels after many years of incorrect nourishment. In combination with fruit and vegetable cellulose it gives "explosive" effect. There is the only one medicine: continue to eat fresh vegetables and fruits in the sufficiently large quantity (portion not less than 200-250 g) to the hungry stomach and to collect the patience.
Vegetable cellulose will clean from the bowels a basic quantity of "rubbish" and unpleasant phenomena will cease during 2 weeks. In this case it is necessary to drink not less than 1,5 l of pure water during the day, since cellulose is derived well from the bowels, only with a water.
To probably superfluously recall that salt and large quantity of servicing in the lettuce will lower "clearning" vegetable effect almost to zero.
And of course the described "therapy" is not applied to the people with the serious chronic diseases of the gastrointestinal tract.
