Otoh, it was the answer given to the doctor in the context of a sports exam that resulted in an intervention for a friend’s D.
D was "supplementing " her restrictive eating regimen with XC. The mom was concerned but the MD connected the dots between her choice of sport, etc. and was able to address before it became more serious.
If you don’t want to answer, don’t. I understand why someone might not want to answer, just like they might not want their weight in the file. But I am not really seeing evil intent in this, especially as abuses of athletes (by coaches) and concerns about mental health (including eating/exercise disorders) have come to be better understood.
