How to make every sim fat?

[mecob3]

I want to make every sim fat in a town for a movie. Is there any way I can edit the game files, or download a mod to do this?

Just replace every rabbit hole with diners and fast food trucks.

The NRaas MasterController should do it.

Just select every Sim in town (from the computer or town hall), and then under Intermediate set their weight to 1.
