Don't let a pregnant woman get too hungry. Do not deny her proper nutrition for extended periods of time, or you might be at risk of a binge. And, ironically, the binge may not include "proper nutrition".
The binge could include an hastily consumed half bag of sour cream and onion chips. It might be followed with a large glass of chocolate milk to tide her over until juice can be properly mixed from concentrate. It could then include a proper meal of four meatballs and some broccoli gratin because she might have a conscience after all. And that could be quickly followed with a Super Jos Luis eaten properly on a white dinner plate with a fork. The entire process could take up to an hour and a half....or less....depending on just how famished you have let her become.
