There are NAI tags specifically for fats. As well as tags that respond thanks to text encoders understanding them pretty well. The models that were merged should allow for an understanding of the following tokens, even if they aren't typical danbooru tags.
Your general {{{bigger}}} tokens are the following: thighs, hips, legs, ass, boobs/breasts, belly, fat, chubby, plump
The first three should always be qualified if used, and the 4th and 6th tokens can also be qualified but it isn't a requirement. (I haven't tested the breasts token, so I can't say if that needs to be qualified) Never qualify the last three tokens. (Note the 4th token can end up making your gens into a rear shot, so be careful with that)
Your qualifiers are as follow: wide, thick, fat, big, huge.
Wide should almost always be used with hips, thick should be almost always be used with thighs, fat can be used with legs and arms. big and huge should be used with belly, and breasts/boobs.
The fat, chubby, and plump tokens all work at moderating overall genned size to some extent, and you should use one of them if you want consistent fats.
With Aurora Borealis, you will have success with lowering the weight on certain tags in order to get what you are looking for without going too far. (belly:0.4) will give a relatively small belly, while still increasing waist size.
It is possible bbw and sbbbw are tokens that are recognized by the clip encoder, but I have not tested this so YMMV.
