I understand that your metabolism "resets" itself -lower than it was before-if you don't eat for a few days. (that is why starving yourself doesn't work) But does the same thing happen when you are ill? If you can't keep anything down, does your body recognize that, or does it think you are starving yourself? I haven't felt very good for the past few days, but I have been trying to eat little bites here and there because I don't know the answer to the above. Do you know?
