I believe it's because our metabolism speeds up at that time of the month, therefore our calorie consumption needs to be increased....(Apparently that's why womyn eat more at that time of the month, but dont put on any extra weight?!)
I have no idea if that's true or not, because I haven't studied it myself, but that's what I was told :D
yeah, still i wonder 'WHY'!
i usually eat 3000-35000 a day, and 4000+ on my pre-days.
Yeah, 3000-3500 si about what I eat now on average. At the time, I was eating less while I streeetched my stomach :) I never had this type of monthly craving while eating cooked food, so the whole idea of it was new to me. I basically just eat alll day for a week or so before my periods. I don't even keep track of calories - too busy eating.
