I splurged a little while back and bought a body fat analyzer from Amazon. The scale wasn't moving, yet I was seeing a difference in my clothes (my jeans are getting downright baggy). I'm so thrilled with it. I've been tracking my body fat percentage with it since late January and have seen changes there even when the scale didn't move.
January 25 my body fat percentage was 35% (I know, eep).
Today my body fat percentage is 33%.
I'll take it! Fat loss is what is important, not 'weight' on the scale. The scale doesn't care if it's new muscle, water, or peanuts!
So, I'm enjoying my new toy, and learning along the way. That's what it's all about.
