Toddler not eating

I have a two year old daughter that doesn’t want to eat. She has maybe 4 things she will eat. Rice, fries, chicken( occasionally) and cookies. Idk how to fet her to eat again. She’s going to start losing weight and it’s not my fault. I’m trying to make her eat but I can’t force her, she’ll just cry and scream no I don’t want it... any ideas or tips ??
