wouldn't she want to count calories instead? (she's a damn scientist, she could figure this out if not so lazy)  It's actually easier than a points system.  Do about 5-10 min of online research.  Pick your daily caloric intake number.  Look at the package of stuff you are eating, and add it up.  When you hit the daily caloric number, stop eating. So really, it just involves counting and adding.  Nothing difficult like subtraction or, heaven forbid, multiplication! And yet, like their waistlines, it is still too much.
