LeFish There is also a stomach % meter too
I remembered this from the first game, though it was just a food meter. Each character had their own favorites etc. as well. I remember frantically jotting down which character liked what style of ramen so I could get the most ability boost for my buck and get the best reaction from them as well. (Which was also reflected in their voice samples)
Such a silly type of thing but they really went for it and it ended up being a fun part of the game for me. Especially when you get to the drug store and can start buying digestive aids? Really, okay then!
