So yeah, what i'd like to see ingame is a system of "exercise" (doing physical activities: like mining, chasing animals, long walks) and fat generation (eating lots of flour based food, or food in general. And not doing demanding physical activities, the ones who sit inside the palli all day). While you do exercise regularly you'll have fit body, but if you dont or you eat too much i would be reflected on the character as it would in real life.
I didnt really thought about penalties, but it'd be kind of useless because it wouldnt interfere their particular activities(or it could and they should leave the pally? idk).
Just wanted to see what people thinks and really hope devs could at least read it and give it a little thinking, it'd be really fun.
