Help me get my daughter to eat

This is my first post.  I have ran out of places to turn.  No professional,  blog, or research article has been able to give me the information I need. If anyone who has a daughter or son with anorexia and has been able to get them to eat,  please give me some tips.  All the advice tells us to keep telling them how wonderful,  beautiful etc they are.  This doesn’t work. Taking away the iPhone or broadband router does work.  But it’s wearing us down. She’s attending “therapy”. They want to admit her to a psychiatric unit for adolescents which I know will do more harm than good.  I know the best way for her is to stay at home.  But if anyone who has been through this has any tips., please please share 💔
