Zero diet

from Wikipedia, the free encyclopedia

As a zero-diet (even total fasting ) is a radical weight reduction - diet called, one takes away in over a longer period no solid food, but only low-calorie liquids (. Eg water and herbal teas) and possibly supplements . As a result, the body quickly loses muscle and fat tissue , because it has to fall back on its energy reserves after a few days.

Healthy people can survive without food for at least a month.

A zero diet is not to be equated with fasting , although there are forms of fasting that have the same principle, namely the complete absence of food . But the goal is different. While the zero diet is about weight reduction, therapeutic fasting aims at physical regeneration; fasting often has a religious or spiritual background.

criticism

Zero diets are criticized by most doctors and nutritionists as being extremely harmful to health. Symptoms such as tiredness, physical weakness and poor concentration are inevitable, as with any form of starvation . Possible risks are the occurrence of gout and disturbances in the mineral and fluid balance when eating for a long time. After just a few days, there can be severe deficits in essential vitamins.

The carbohydrate stores stored in the liver in particular are usually used up after three days. Then stored fats are converted into keto bodies to produce more carbohydrates , which are then used to supply the body with energy; the so-called starvation metabolism then sets in . Since no proteins are absorbed, there is a loss of muscle mass.

Since the body adapts the metabolism with a zero diet and reacts to this artificial hunger phase with increased fat storage in the following period, the so-called yo-yo effect almost always occurs , so that the diet goal is not achieved. However, this risk can be countered by carefully building up your diet; Overeating too quickly after fasting can lead to refeeding syndrome and can be fatal. Prolonged food deprivation can be harmful.
