Have researchers found out why in the hell women eat like truck drivers with a tapeworm when that time of the month comes around?

I didn't eat lunch today because I had to run errands right after work.  I came home and ate some leftovers from yesterday because my stomach was growling like pissed off bear.  I was satiated for approximately 20 minutes.  Now I am RAVENOUS! I'm trying to wait until the husband finishes cooking.  He was so excited because he wanted to try frying chicken for the first time. I told him what he needed and how to go about cooking it. Now it is smelling so good that I'm salivating!
