With permission of the author, I present coldsteelj’s Sims 3 mod.
These are just clothing items you put on your sims that change their body. They don’t affect the vanilla body.

Tips
If you want a greater range of body shapes, download Consort’s “2x Weight and Fitness Integration core-mod”. It comes in three versions: Standard (x2), Mild (x1.5), and Unlimited. The body can get pretty weird-looking at extreme sizes, so I use a combination of body sliders to diminish the problem. You can pretty much get whatever shape you want, with the right sliders.
If you wish to change the rate of WG, download the “Sims Weightwatchers” by severedsolo . Open the mod with s3pe and find the line called "kFatBodyShapeChange value=“0.7” (It’s towards the top). Change the numerical value. The higher the number, the slower the WG, and vice versa. Go by small increments as it is very sensitive. I have it at 1.3.
This is just a personal modification. I do not condone stealing any mod and uploading it as your own.
I’ll add some more tips as I think of them. Feel free to add your own.
