Losing weight depending on the timing of fasting

During fasting, the body completely switches to internal nutrition, the basis of which is fat accumulation rights. For normal life during the day with complete water starvation, the body is enough 300-400 gram of own fat, the cleavage of which forms glucose, which is the main vital activity of man.

With a full transition to internal nutrition for exactly this amount of grams, you will lose weight in a day. But the transition to internal nutrition is not immediately. This requires some time, the duration of which depends both on your experience of fasting, and on a number of other reasons. The average period of such a transition is 5-7 days, but some people have a crisis later. Basically, this applies to beginners, whose transition to internal nutrition can be delayed even up to 10-11 day. Before this transition, which is called an acidotic crisis weight loss is significantly greater and most often is 1 kg per day. With significant obesity and beginner weight loss these days may be even more - up to 1,5-2 kg per day. The onset of an acidotic crisis indicates a complete transition to internal nutrition. The organism begins to spend its resources very economically. Weight reduction slows down, at first to 500 grams per day, and then to 300-350 grams per day. Such weight loss usually lasts the entire period of fasting even despite physical exertion. With the regular use of fasting, the body quickly moves to internal nutrition and can more economically spend its own fat, so weight loss can be less.

Here is an approximate weight loss graph for water starvation:

with 1 on 7 day of fasting - about 1 kg per day;

with 7 on 10 day - 500 gram per day;

with 10 days and the whole subsequent fasting period, weight loss is 300-350 gram per day.

Table of approximate weight loss in water starvation of different terms.

Duration of fasting Total weight loss
1 day 1 kg
3 day 3-3,5 kg
7 days 7 kg
10 days 8-8,5 kg
14 days 9,5-10 kg
21 day 12-13 kg
40 days 18-19 kg.

As is known, loss of 20-25% of the total weight is considered safe. As can be seen from the table, even for people with a low initial weight, starvation of short and medium terms is quite safe and can be used to treat and prevent various diseases.
