This model generates women with wide hips and curvy bodies. It's fundamentally different from my other BBW model since it was trained under an entirely different dataset, containing zero 3D and real-life images. Usually it can perform well on its own, but it'll mostly generate thick voluptuous women. If you want them fatter, you'll have to guide the model a little more (usually an issue with the base checkpoint and not the training).
I recommend a strength of 1.0 for this but do whatever you want. I don't care.
