Are depleted glycogen stores repleni...

According to Stephan Harrod Buhner (and no other source that i was able to find in about 45 minutes of searching), our glycogen stores which are depleted in the first couple days of fasting are restored once we are in ketosis. Is this indeed true and does anybody have any specific information (preferably which includes good sources) on how exactly this works? His excellent article is found here:
http://gaianstudies.org/articles4.htm
Also, how many days into the fast would it typically take to fully replenish this glycogen? The body somehow knows not to use the replenished glycogen at this point as it continues to metabolize fairly small amounts of protein to obtain the minimally necessary glucose for functions that ketones can not perform?
Much thanks :).

Remove toxins from the body, restore digestive function, lose weight and keep it off.
..the terrain needs to be 'tromped', correct?
Hi Sun-- Isn't this covered 'exhaustively', (sorry!) in the NH literary writings? Chris B1
must have them all collated.
i mean this ( leading questions, ???)
genuinely, while/so
I must confess: I read,
read a LOT, and then
promptly "forgot"...
(now I read
much less...) why????
As the holy teachings teach,
the holy books WILL take the place
of 'remembering'...they just 'move in',
upon one's devotion to truth...and these
(they) are floating in the ether..
and MAY be
located----These inspired "books".
I took that idea
to heart.
and found
what I have 'needed'.
May it be so,
for every one.
:-) best, C
)))))))))))))))))))) and just, Hello!
May you be well! and happy! and every one
you 'know'.

Hello Dear Chiron to you and yours as well :). I hope this is specifically covered in the literature but i don't recall ever reading about it and in the time i spent searching for this answer i came up empty.
"..the terrain needs to be 'tromped', correct?"
From my perspective it does, yes :).

Hello Mighty,
Glycogen is basically the storage form of glucose stored in the Liver and to some extent within the muscles: it is classified as the main fuel of the body while eating and especially for the Brain.
At the beginning of a fast, you will burn glycogen, fat, and some protein (protein-sparing) for energy.
After about two weeks, you burn mainly fat, so the process is one from glucose-burning as our primary fuel-source while eating, to one of fat-burning or ketosis while not eating; ketones from fat-burning then become our main fuel supply once glucose stores are depleted.
It is only when the fast is broken that these reserves are replaced, and that includes the glycogen stores of the Liver and of the muscles, which overall lose about 50% of their glycogen (not to be confused with protein).
Glycogen stores are not replenished during a fast as the body only requires minimal amounts of glucose to feed the Brain and other functions.
In other words, this Stephen H Buhner is largely incorrect, except for the point where you quoted...........
"the body continues to metabolize fairly small amounts of protein (protein-sparing) during a fast to obtain the minimally necessary glucose for functions that ketones cannot perform?"

Hi Chris, thank you for your reply :),
"It is only when the fast is broken that these reserves are replaced, and that includes the glycogen stores of the Liver and of the muscles, which overall lose about 50% of their glycogen (not to be confused with protein)."
I am surprised to hear that we only lose about 50% of our glycogen in a fast. From my interpretation of whatever i have read i always believed it was 100%. Is this because the body has a certain minimum (50%) it must maintain, below which would be detrimental?
"Glycogen stores are not replenished during a fast as the body only requires minimal amounts of glucose to feed the Brain and other functions.
In other words, this Stephen H Buhner is largely incorrect,..."
How can he have made such a mistake? (i mutter to myself rhetorically).
"except for the point where you quoted..........."
'"the body continues to metabolize fairly small amounts of protein (protein-sparing) during a fast to obtain the minimally necessary glucose for functions that ketones cannot perform"'
Those were actually my own words :D.

Hi Mighty,
It is the muscles that lose approx' 50% of their Glycogen stores during a fast, and where that is used sparingly but sufficiently to feed the Brain, which is hardly able to feed from ketones.
The body economizes this usage of glycogen as it does with protein and other nutrients such as electrolytes, in its own innate way in preserving nutrients for as long as possible, so as to stave off the onset of starvation. If this did not occur we would be literally starving to death within a week or two at the onset of a fast, and regardless of how much fat we possess. The body has its own independent intelligence which many are unaware of.
It is almost 100% of the Glycogen stores of the Liver that are are utilized but not really replenished until we resume eating.
Americans might refer to the bodys ability to utilize glycogen from the muscles, in the absence of the stores from the Liver as "back-up".
But you were spot on Mighty with your own quote. I just inserted "protein sparing" as Dr Fuhrman MD calls it. The same can be said for "glucose-sparing" as the Livers supply becomes exhausted and the body knows it needs some glucose for the Brain and other functions. Good post btw.
"the body continues to metabolize fairly small amounts of protein (protein-sparing) during a fast to obtain the minimally necessary glucose for functions that ketones cannot perform"'

This is a reply to # 1,854,889Hi, I'm new here so sorry for replying to an old thread, but hopefully someone will answer. I just broke a 9 day medically supervised Water Fast today. How long does it take the glycogen stores to be fully replenished? Would appreciate cited sources if you have any readily available.
Much thanks,
Christine
