Hey, at least you are moving in the right direction. I try to tell my wife (since she wants to lose weight/gain strength) to go more by how you feel, look in the mirror and how clothes fit versus being held captive to a scale as her body changes (has not worked yet).
So, you are probably feeling thinner since your body comp has changed but the total weight is staying stable, all in all not a bad thing.
Take care and enjoy the weekend.
