In the UK, non-private eating disorder services, when you contact to be referred, ask you how much you weigh, and they determine how urgently you need support based on this. I personally believe that this is very harmful to all others suffering massively, despite not being classed as underweight. However, I do appreciate the demand that these services have and I understand there must be a system. This is why I believe that it should be about how much weight you lose within a recorded period of time. I believe this will be a much more effective way of deciding, because people suffer horrendously no matter their body size.
