That's great! Like you said, the scale can lie. You could be losing fat and gaining muscle mass. In that case, I'd say your next step is to make sure you're eating enough protein in addition to the right amount of calories so as to provide your body what it needs to build that muscle. I use MyFitnessPal to track my macros.

Fun ways to track your progress other than the scale include body measurements (with a measuring tape) and pictures! Or DEXA.
