Sweet! Are you going by the scales's body fat percentage? Mine is notoriously inaccurate - and always tells me I'm way above where I'm actually at (even though it does have the sense to go down when I lose weight). I actually calculate my body fat % using my measurements at this website: scientificpsychic.com/fitness/diet.html
I love it because it also calculates your approximate lean muscle mass, and I LOVE watching that number go up, up, up! while body fat % goes down, down, down! :)
