Wow, you actually tried it!! I'm half laughing because I can almost see myself trying it in the name of science
. But, honestly it doesn't surprise me the results you had. I was not successful in overriding that urge at twenty when being skeletal was the ONLY important thing in my life. Since that is not important nor desirable now It only makes sense I'd give in to the pleasure of the binge despite knowing what I know. And those brain pathways are there no matter how week (in the same way as I still know how to play the violin although not as well as I once did). It would be quite interesting to give this knowledge to someone who has never ever binged and ask them to starve and see what happens. Kidding
it wouldn't be interesting, just possibly cruel.
