Was discussing this in depth, but basically here is the idea.
If your character is someone who just cooks, or sews and doesn't do any hard labor (or use a lot of stamina) such as farming, hunting, mining etc...
Your character slowly starts to get fat. The fatter your character is the slower you move in each movement tier. And then your character becomes actually fat.
I would love to see some fatties walking around in the world. LOL
please?
