I've been listening to the Fat 2 Fit Radio podcast - the hosts' attitude is that if you want to be a thinner, fitter person, what you need to do is to start eating and acting like a person of the size you'd like to be. And that you shouldn't eat below your basal metabolic rate, or you risk going into starvation mode -- and 1200 calories/day is the BMR for a 30-year-old woman who is 5'4" and weighs 89 pounds.
So (making up numbers, because I don't know your stats), if a 30-year-old 5'4" woman weighed 150 pounds and wanted to weigh 125, but isn't getting any exercise (sedentary), the calories she'd be eating at her goal weight are 1604, so she shouldn't eat any less than that. And they admit that because of the vagaries of personal metabolism, fat/lean body mass composition, etc., you may need to tweak that up or down to find the sweet spot for you. They've got three bodyfat percentage calculators that can give you an estimate you can plug into the BMR calculator and get a better estimate on that.
It's a fairly interesting, sensible philosophy. Their site and their various calculators are at http://www.fat2fitradio.com/. Of the two hosts, one's a PE teacher from Canada who lost some weight himself following that, and the other is a guy from California who has lost over 100 pounds slowly, and is near his goal weight now. He'll probably be moving into maintenance before too long.
