Weight loss and Heath concern?

I need advice from someone who knows the female body and how it reacts to weight loss and toning. I have lost two Jean sizes since October I have not changed my life style or my diet. I do feel amazing and would love to continue lossing weight cause I am a bigger girl but I don't want to do it in a way that will harm my health nor do I want to starve my self or look like I'm trying to become a swim suit model. I just want to be more healthy for me. But first I need to understand how I have managed to lose Jean sizes and almost no weight doing absolutely nothing?
