Munchies:
Personally, I like to give a basic description of a character and focus on the experience of being fat. Things like discovering new rolls, relearning your center of gravity, or outgrowing old clothes. That way you don't have to worry about being too precise, but the reader can better immerse themselves in your world.
Something of this idea has been of the more fun scenes to write in my ongoing series actually! I was working on how to describe the momentum that can carry you and how adding to that weight, you can feel that and how it carries and shakes oneself when exerting great forces on a larger body, or the kind of impact that it can carry. Describing scenes of launching someone and having them pivot around from the accelerating forces of an intense fire spell makes the magic setting really fun to write in. Slice of Life has its place in our knick of the woods fairly prominently, but sometimes having an intense action scene is both refreshing to write, and to read as we do not get a lot of that in our kink genre, at least from what I have noticed.
Munchies:
A lot of people hyper-fixate on fetish spaces for fetish work inspiration. That's all well and good, but if you want to ground your story in realism, the weight loss and fitness community is the way to go.
You will find people of various sizes and shapes chronicling their experiences in vivid detail. There are precise measurements and they show their bodies off at multiple angles. Super useful.

For sure, a lot of mainstream culture is cultivating losing weight rather than gaining and I should look at it as a resource rather than the opposite vibe of what we have here in our community. Maybe that hyper-fixation on the community causes that snake-eating-its-own-tail sort of mindset of focusing solely on our kink aspect, rather than balancing out the two extremes for a better-balanced story with more room for nuance.
I did have this idea of character a character going through a journey that finds the happy medium of being large while trying to live healthy after extreme dieting and gaining didn't help bring the acceptance and happiness they were looking for in their life. But I kinda backlogged it as something I'd have to just write for my own sake rather than publishing around places like here.
Just like a good artist has a working understanding of biology - regardless of style, a good writer should too. You can't learn that from fetish spaces. That's like learning how to have good sex through porn. Doesn't work like that.
