I'm looking this old manga about a girl who has super big appetite. she could smell food within meters away and it made her family always left with a little portion. her parents often cried because how big the food money is. when she ate, she could swallow the food in one gulp (somehow it looked scary)
It sounds an awful like any Han Yu-Rang or Mi Ri Hwang manhwa in existence!!
On a more serious note, some older series with similar female leads that come to mind include Sailor Moon and Fushigi Yugi, but from your description, I doubt that it is either of these series.
