This diet lasts 13 days and although difficult, it is efficient. The metabolism's change is that fundamental that at the end of the diet one can come back to the normal alimentation without gaining weight for two years. If the diet is respected daily, step by step, one can lose all the fat accumulated in tissues. The diet must last exactly 13 days, not more and not less.

Recommendations:

Any aliment added beside the aliments allowed by the diet (a candy, a chewing gum, a biscuit, a glass of beer or wine) imposes the immediate stop of the diet as it has no longer effect. You can start over again only in six months. In case you cannot resist to keep the diet more than 6 days (respecting all the alimentary indications), stop it and begin again the diet after three months.
If you are hungry, drink water, at least 2 l/day.
The lettuce should be fresh. 
The code (the fish) can be replaced by trout or plaice.
Coffee cannot be replaced by tea or the other way round.
The natural yogurt is the non- pasteurized one, without sweeteners or fruits addition.
