I have always known that for every gram of stored glycogen in muscle and liver it holds three grams of water. I even see this information on this website.

I am looking for some additional sources that state this information, preferably any published research that also discuses how depleted glycogen stores contribute to weight loss. Does anyone have any? If you cannot share the link as that is blocked on the forum, please let me know the search query you used to find a result with the information or the name of the website.

Thank you in advance for any help you can provide.

Bryan

Have you already tried a Google search? That's all that any of us could do.

I actually found one. And it's contradicting. Take mind that this is only an abstract, and it was done on rats. So the reliability is not that high.
http://www.ncbi.nlm.nih.gov/pubmed/7068293

"These data, therefore, do not support the commonly accepted muscle glycogen-to-water ratio of 1.0:2.7 (g:g). Further work is necessary to quantify the exact amount of water that is actually associated with the glycogen complex."

Glucagon (in title)

Glucagon is a hormone. It is completely different from glucose.

Glucose
There is plenty of information on how glucose cause water storage.

Protein

It is a dieuretic, just for you're information.

glycogen =/= glucagon

Glycogen is an energy source in your muscles, which you deplete during exercise, and then replenish with carbs. It is a polysaccharide made of several glucose molecules.

Glucagon is a hormone that helps regulate blood sugar, acting in opposition to insulin, raising blood sugar. It is created by the pancreas and used to convert glycogen to glucose in the liver.

So I think one is essentially a chemical that breaks the protein bond of the other to release the individual molecules it contains.

So they are related but hardly the same thing.

I would say that glycogen doesn't hold water so much as glycogen and water levels are the result of the same thing, carbohydrate intake. Notice you get a little rapid weight gain initially when you carb up for a bulk, you also get a little rapid weight loss initially when you get on a ketogenic diet.

So I would say it's a case of "post hoc ergo propter hoc". Because relation and causation, much like glycogen and glucagon, are similar, yet entirely different things.

isn't glucagon a hormone that kinda acts as a buffer to insulin?

EDIT: Should probably read threads before I post

Sorry about the mental brain fart when typing the title. I did not mean to reference glucagon at all. I have heard the three grams for every one gram before, I thought it was from a text book, but I have not been able to find it again except as a rule of thumb versus any evidence. I have tried Google search and the only thing I found was a page on this website that says it but no reference. I am looking for anything in humans that supports or counters the three grams of water per one gram of glycogen.
