This problem of flipping out amongst doctors seems to be quite commonplace. They often seem to think that fasting is bad for you.
Is this condition called Doctoritis perhaps? Or maybe Doctor-eaubia, and the Doctor is Doctor-eaubic? I am not sure what the cure is, but I think a Water Fast may help releive them of some of the anxiety associated with Doctoreaubia. A group fast of many doctors may even cure the syndrome, as they seem to require this pre-requisite activity before believing something. All I can say is - thank god my doctor does not require a group study before he approves of me eating apples!
