If cells 'stay alive' after death and it takes, technically, ~18 hrs to deplete glycogen in living humans, what happens with the energy obtained from glycogen?

Just lost I imagine. Only 25% of fuel use in skeletal muscle goes to things like contraction anyway, most of it is lost as heat under the best circumstances.

Also keep in mind that anerobic glycolysis (carb usage) is pretty inefficient in the first place, the amount of ATP being made isn't that high.

So if I were trying to deplete muscle glycogen before a carb up, would death be a good way to accomplish this?
