I think this is not true in ketosis, in which most cells burn the
ketones directly or, after a period of adaptation, free fatty
acids. Some cells, such as the cells in fast-twitch muscle fiber
and certain brain cells, have to have glucose, so these would
need adequate B1 to use it. In short, the B1 requirement may
depend upon whether or not one is in ketosis.
I don't recall the RDA for B1. Do you know it?
