Measurements

I've kicked it into high gear this week and lost over 8 pounds. Utilizing a massive eating shift to "normal" portions and dancing every night has brought this about. However, I used the Spark measurements section of the site, and on 1/31/16, I measured the same as i do now. Actually the only difference is in my thigh measurement. Everything else is identical or a touch bigger. Is that how I tell it's water weight I've lost? If it were fat, would the inches be changing?

Hopefully I'll see progress in the inches department some day.
