[QUOTE="Oldvatr, post: 1922915, member: 196898"] I think the problem may be linked to athletes and endurance ones most of all, where the low blood glucose can lead to the muscle scavenging from the local cells around to supply energy surge, Looking at the Krebs (Citric) cycle, then muscles can store glucose from blood as local glucogen, or use glucose direct from blood, or use stored glucogen previously stored in the local cells, But the local stores fo not hold much, and the liver is signalled to release some from the adipose tissues - but this takes time to happen, and so there may be a larger demand than can be locally provided, so the body burns what else it can find, such as ketones or raid other nearby cells. So I suspect it is the cells nearest to the active muscle bundles that get scavenged, and only under extreme duress while blood sugar levels are low in the blood, I am thinking of Paula Radcliffe during the Tokyo Olympics during the marathon walking event, Maybe Tim Noakes has a better handle on this aspect.
