Glycogen Storage: illusions of easy weight loss... (http://www.ajcn.org/cgi/reprint/56/1/292S.pdf)

Aside from the discussion about potassium (which we already knew dropped pretty harshly in the first days of ketogenic dieting), glycogen dumping on a ketogenic dieting is something I think I understood pretty well before this "study". We're talking 11 people doing 4 days of dieting. Anyone who has done a ketogenic diet can tell you that the first four days don't really bear much relation to the next X number of days. So, I don't think this complicates anything. As the old wisdom about this type of dieting goes, you can pretty much toss out your first week or two of weight as being water that was bound with glycogen.
