No he didnt. HIYORI offered umprompted that she will offer anything if they save them. Than Zoro said he wants a meal AND a drink. A classic samurai call back like the usual shit zoro does, also content with that he does nothing for free and he is someoen who doesnt share.
There is not 1 panel of him being hungry. And infact when he wakes up he doesnt yell for sake/food (which happens in canon) but is still obsessed about killer and wants even to leave without eating anything first, just hold back by him getting fucked up (which also goes against the headcanon, as the injury is so severe he makes a luffy face as soon as hiyori pulls his arm back)
Maybe if the only one who buy your theory is you and your scholar friends its not as objective fact as you think it is
