Amber, The lower your weight, the harder it is to drop more weight. The first 5 pounds come off a lot easier than the last 5.
It's telling that you say you want to lose more weight, but want to do it all by exercise, not by further calorie restriction. The lower your weight the more important it is to do both. If you don't want to cut back on your food, are you really sure you want to lose more weight? If you are happy where you are, why change?
In the last 6 months I have managed to get my BMI from 19.6 down to 18.2. At the low end, continued loss has to be primarily through calorie restriction. It IS a sacrifice that I am willing to endure, at least for now. There are risks to being too thin: if I ever come down with the flu, I would have to be hospitalized for IV nutrition because I can't afford to lose any more weight. I have to put up with people who think I'm anorexic (I'm not. I make and eat 3 meals a day.) And I could put 5 pounds back on in a week if I let myself.
You have to figure out what weight you want, and whether or not you are willing to do whatever is necessary to get there.
No one ever got up in the morning wishing she'd eaten more the night before.
