Sooooo…didn’t read any of that dump

but ARE WE sayin’ that ketone burn bodies are superior to glucose burn bodies? Heehee

Ketones are partially-burnt fats, just as charcoal is partially-burnt wood. So it takes less oxygen per molecule to finish burning them, which is an advantage in the case of a heart muscle when the arteries are clogged. Fat molecules are too big to cross the blood-brain barrier, but ketones can cross it, which is why ketones feed the brain so well.

In terms of metabolic efficiency, the energy and oxygen costs of metabolising fatty acids are pretty much the same as for glucose, the difference being that fatty acids can only be metabolised in the mitochondria and the process is a bit slower, whereas glucose can be metabolised anywhere in a cell and glycolysis is a bit faster than fatty-acid metabolism. Glycolysis also produces damaging reactive oxygen species, whereas fatty-acid metabolism does not. (This is why our mitochondria become damaged on a high-carbohydrate diet.)

And apart from that, part of the damage glucose does in the bloodstream is that it binds to things (such as your haemoglobin), creating advanced-glycation end-products. As we know, the body needs a small amount of glucose and is capable of making all it needs, in the absence of dietary carbohydrate. It is the excessive serum glucose levels resulting from eating too much carbohydrate that cause the problems.
