First, congratulations on being so consistant in your Pilates. And I'm sure you are much more toned and how wonderful is it that your back side is rounder!!

And I agree with the previous post, you do need some cardio. The other thing I would recommend is to do a food journel. Write down everything you eat. You may be surprised. And even if you are eating well, at the very least, it will put you in touch at a deeper level with your nutrition.
