Thanks for the translation, but I don't think that wanting to be in shape for someone you love is "fatphobic", the boy in other chapters also cared about his hair (maybe that could be "baldphobic"? I know some men become depressed for losing their hair), so I don't see why the girl couldn't care about her looks too, but that's my two cents, I just hope that you guys don't get demotivated from keeping translating this over a joke, because your work is appreciated, so thank you anyways.
