as someone with an ed, who has cycled through all sorts of behaviours, NEVER STARVE YOURSELF. eds function kind of like an addiction: you think you can just stop once you get [X] (in this case starting HRT) but you won’t. and you said it yourself, the weight you “need” to lose is nonexistent. estrogen can fuck with your bone density and so do eds. you don’t osteopenia or other health issues. and you need to have fat to redistribute it: so eat. please. this isn’t a path you want to take.
i’m going to sound very dramatic, but there are two options once you go down that path: recovery or death. i have made friends to cope with my ed, and many of them are dead. it is not worth it. please, please don’t stop eating. you are going through puberty — growing needs energy!! you can’t grow from nothing.
