My zois do not gain weight even when eating junk food. Is this a bug? Or am I doing smth wrong? How can I make my zois plus size without using donuts?

Set the Game Options ON

Options \> Simulation  
Dynamic Physique  
Dynamic Muscles

I don’t have the game open, so the exact option names could be different.

I think you have to have your Zois keep eating when their Hunger bar is full for them to gain weight. It used to happen really easily in earlier versions of the game, but I think that’s been changed. You may have to do it several times over.

they get skinny/small too easily with the dynamic weight on; I leave it off in my game bc it makes my chubby zois thin not even a day after leaving CAZ
