Your welcome jasmine,
However, fasting to completion is not really a myth: it has been done many times over. Take the cases of Mr George W Tuthill and Mr J Austin Shaw under the guidance of Hereward Carrington and Dr B in his classic work: "Vitality Fasting and Nutrition: a Physiological Study of the Curative Power of Fasting" P.192 & 206 and in particular with Chapter V111 on how and when to break the fast.
It also depends on the actual definition of "Fasting to completion", where in the Hygienic sense this would mean undertaking a fast until the return of genuine hunger, and not necessarily until all of the bodys food-reserves have become exhausted.
A fast to completion would mean.............
"Nature will always indicate, by unmistakable symptoms, when the fast should be terminated, and it should never be broken prior to these indications and to the return of natural hunger! No matter how long a fast may be necessary, the same rule holds good in every case. Nature, in her wisdom, adopts this course and the rule is infallible. If a fast of only two days is necessary, in order to clear up the system and recover health, then hunger will return at the end of the second day. If, on the contrary, two weeks or two months are necessary---then natural hunger will not return until the expiration of that lengthy period. And thus we see that natural hunger will always return when, and only when, the cause of the disease is completely expelled from the system, and the body is once more restored to perfect health".

The comparison with Nature isn't necessarily a sound one, as animals in the wild have to contend with predators and food scarcity where both have a strong influence on their fasting-length thru injury or illness.
Humans however have the luxury of being able to avoid the former reasons for terminating a fast, and where we can exploit our innate and biological powers to our utmost advantage.
In this way we are able to "fast to completion" if required, but in todays World we seldom have the need for this kind of protracted fast, and which most would need in order to free themselves of toxemia completely and maximize the healing capacity of the body.
Sound nutritional principles as in a plant-based and nutrient-dense diet are slowly coming more prominent in curing/reversing and preventing disease.
Fasting still has its place in an overall Hygienic regimen, but has taken on an out-of-proportion prominence in healthcare and recovery, while the other agencies of life, and lifestyles in particular, should and could play a far more significant role in achieving greater longevity, good health and freedom from disease.
Sidhwa was a disciple of Sheltons that is true, but we must bear in mind that Shelton was the most experienced fasting supervisor EVER, having single-handedly saved the works of the "Masters" into one huge volume: Human Life: Its Philosophy and Laws and supervised more fasts than anyone in recorded history.
Dogma can be born out of experience, and in this case the experience of others who have gone before you and have had a great deal of success in health-recovery. That is the kind of dogma worth having.
I agree with you wholeheartedly, and as I have said before: it is a matter of personal preference as to how and with what to break a fast, and to resist the temptation to overeat, which is easily the case if genuine hunger has returned and all of the benefits of the fast are undone.
