Updated: 2nd Oct 2014 at 2:30 PM - Update the patch-compatibility info.
Released the game patch on 10/01/2014. I confirmed that this mod worked with the patch.
Updating for compatibility is NOT needed. So you can keep using this mod that you downloaded.
And I added information about the compatibility with the patches. For details, see "Compatibility with the game patches" section.
This mod stops daily change of sim's physique (getting/losing weight and muscle).

What is this?

While this mod is enabled, daily change of sim's physique stops.
Sim can keep his/her physique that have been decided in CAS without special effort.

This includes two mods below.

No Fatness

Stop getting/losing weight.

No Muscles

Stop getting/losing muscle.

You can use both No Fatness and No Muscles at the same time.
Also, you can choose only one of them if you want.


Just put the downloaded zip files into your "Mods" folder.
(ex. C:\Users\Someone\Documents\Electronic Arts\The Sims 4\Mods\)

It is not necessary to extract the zip files to use this mod.

I attached mod source codes of python script to the zip files.
If you want to read them, unzip mod files.


Delete this mod zip file from your "Mods" folder.

Compatibility with the game patches

The below table shows the compatibility between this mod and the game.
These are based on my in-game check (I confirm that my mod works by playing the game).

The reason for creating this

In The Sims 4, there is the feature that sim's physique changes automatically in daily life.
For example, sim will get weight if he/she eats too many foods in a short time.

But I think that sim tends to get weight even if he/she does not eat much.
If sim continues to live ordinarily, his/her weight increases every day.

To lose weight, you will need to let sim take exercise.
This means all sims that you want to keep their physique slim are forced to regular exercise.
I don't agree to this specification, so I create this mod.
