With this mod, Sims that aren't gluttons will stop eating as soon as they are fed up - just like it was in the Sims 2. I recommend to use the grandmeal module in combination with my moregrandmeals_tradionstweak. Otherwise, your Sims will not fulfill the grand meal tradition when they don't finish their plates.
With the Neurodiverse mod, you can customize your Sims 4 gameplay to suit the needs of players with autism, ADHD, dyslexia, and other neurodivergent conditions.
