A large majority of the kpop industry is skinny!

I must be missing something because in all the photo's she look's the same. With that said before BP began promoting she wouldn't have been as busy as after and she wouldn't have been working as hard either. Any 'fat' she had would have been converted to muscle especially with her appearance on Real Men 300. She doesn't look anorexic or exhausted so I'm assuming she's doing well enough eating wise and keeping herself rested enough.
