I have to "ditto" everything said above! It all depends on how you feel rather than any chart or 'expert' advice.

I picked my goal weight because it sounded about right for a medium-build, 5'4" (well.... if my hair is sticking up a half inch) female. I will see what it's like when I get there, because last vivid memories only cover somewhere around the neighborhood of 175-200.

I also keep in mind that I plan to carry my exercise through to higher levels which will up the scales since muscle weighs more than fat. As Nat says, if the smaller size clothes fit, I don't care how much I weigh. I suppose it has to do with each individuals motivation, too. For myself, I have never in my life wanted to be SKINNY or look like a model or actress, just me. I want to be lean and healthy, ready for anything life sends my way.
