Yeah I'll be trying to differentiate them more so in the future.
To start of, yeah, the game is a fantasy, and it's not real life, but many aspects of it, do mimic reality a bit more, like the injury system, or the hunger system, eating food, even how after a nights sleep, injuries don't completely heal.
But, we can clearly see, how the recovery rate is way faster, meaning that Lona is like a superhuman, so she could recover fast of course, therefore, I feel like we could exclude feeling sore, and the somewhat basic stuff we feel.
Now, we know that Lona, is technically an adventurer, and all rounder, considering we don't escape fast with hacks or what not, her stamina is well, fine, or rather we know she can recover fast, therefore the 100 swings, in a fight, she should be able to recover fast, as we can see that in game too.
Through many many parts, we can see that although the game might not be trying to simulate to actual stomachs, it still is, like you said to a certain degree, and that degree, is not like other typical rpg games, I cant think one of the top of my head, but it's sense of reality is a more then others.
This is why I dislike, not that I have an issue, but dislike the in battle hunger system, since the game feels way more embedded in this type of irl system.
I'm not sure if I made proper connections and sense, my heads in a jumble right now, so if there's something weird I said don't hesitate to point it out.
