It seems that wikipedia is crashing! Indeed, studies on penguins - and verified on humans - have shown that, after the fat mass has melted, the volume of muscle wasting is almost nonexistent (documentary on therapeutic fasting cited some time ago.)Wikipedia wrote:
Limits and danger of fasting
An adult of 1,70 m, weighing 70 kg, has about 15 kg of fat reserve, enough to keep, if he is healthy, forty days of fasting. But beyond that, the continuation of the fast consumes the proteins of the body. The body catabolizes certain amino acids that can be converted to glucose during neoglucogenesis to supply the brain. Proteins are stored in muscles (including the heart).
Another misconception! Fasting poses no danger even beyond 3 weeks, but the physiological limit is individual, in some a 40-day fast will pass very well and others at two weeks will have to stop."Within the defined limits [fasting less than three weeks in a person of normal build] fasting is not dangerous"
this is correct for a maintenance fast, but more for a therapeutic fast, such as for the elimination of cancer for example or other serious pathologies.For reasons of healthy living, it is not necessary to fast for long periods. A day or two is enough if you drink depurative at the same time (infusion of chamomile, sage ...)

inaccurate.
We "tap" in the muscle long before having burned all the fat.
It is for this reason that all slimming diets (aesthetic or sports) are hyper-protein, it helps maintain muscle mass.
The penguins have reserves which allow them to face the periods of scarcity and intense cold, unfortunately the human being does not have such capacities.
Research carried out by the US army aims precisely to allow, through chemical substances, fat burning without impacting muscle, in order to allow soldiers to hold out longer on the battlefield.
The Paleo diet also targets this.
Janic wrote:that everything depends on the references used. Review the documentary in question, which has been studied by both Russians and Americans, and the conclusion does not go in your direction. Muscle mass, even after the total fat loss, does not exceed 3% (of memory) in both penguins and humans.
Documentary: "fasting a new therapy"
A study of a population of which all individuals were referenced as well as their diet according to harvests showed thata grandmother who has experienced a famine transmits this information to her offspring and therefore modifies the DNA of her grandson, who can develop illness when he has never experienced famine
In the Överkalix study, Marcus Pembrey and colleagues observed that the paternal (but not maternal) grandsons [53] of Swedish men who were exposed during preadolescence to famine in the 19th century were less likely to die of cardiovascular disease. If food was plentiful, then diabetes mortality in the grandchildren increased, suggesting that this was a transgenerational epigenetic inheritance. [54] The opposite effect was observed for females — the paternal (but not maternal) granddaughters of women who experienced famine while in the womb (and therefore while their eggs were being formed) lived shorter lives on average
Young how long, what type of young?
Over 3 days, there are almost no decreases, by cons arrived at 10 days, a young complete causes a decrease in muscle mass which can reach 2kg.
Young people have their advantages and disadvantages, it's like everything.
No, prolonged fasting is not a violent method when it is used with discernment because effectively a fast is a break with an automatic mechanism. But it's like sport, so don't try to run the 100m in 10 seconds after 8 days of training.Not for nothing that we are looking for low-impact, prolonged fasting is a fairly violent method amha. It is better to see if there are not sweeter means to achieve the same ends.

Preconceived idea. If the faster is in bed, he will probably lose muscle like any unsolicited muscle such as quadriplegics who consume normally, but whose muscles shrink.
With minimal activity, walking, jogging, muscle mass does not decrease and, even more, allows better endurance. For the few fasts of more than 3 days carried out by accustomed fasters, no muscle wasting noted. There are websites dedicated to fasting with lived testimonies: consult them!
