I saw a transcript of what seemed to be a post from her OF (I can't verify myself, haven't been subbed in ages) that seems to confirm this to some extent?
Basically she said that she got super insecure about her body recently after a remark that someone she slept with, causing her to go on weight loss drugs, then try to regain the weight after a panic session to try and fix what she was doing.
Not to play armchair psychologist but somehow I'm doubtful that she was perfectly okay before that one comment and then spiralled solely as a result of it, I imagine there was probably some less-than-great self-esteem before then that she was just kinda holding in. idk, maybe I'm being weird and seeing things where there aren't any.
It's a shame. It's not like my opinion matters but she's been hot ever since the Tumblr days, giant tits and big belly and all. Then again, maybe that's just my taste, lol.
