I'm confused about the body shaming... are people dissing on the actresses or the fans? Or both?

Neither makes much sense to me. Admittedly, I think most actresses these days could stand to put on a few pounds, but they can't, because their profession demands the super skinny standard.

And actresses become successful because they *can* meet the Hollywood standard of beauty and thinness. To expect fans, normal people who like to watch TV and read /write fanfic for their hobbies, to be as gorgeous is just silly.
