It can, but not in a specific way. If the center tank is empty those pumps are off, but the weight at which that occurs varies. If you have a lower payload maybe fewer ovens are used to heat meals, but I think galley loads would be shed if you were engine out. It would help to know the condition the burn numbers are for. Engine failure? IDG out dispatch?
I don't know the answer to the OP's question - I'm speculating.
