I have no scale

I have no scale to tell me what my weight is but that's fine. The numbers on the scale never seem to move. I'm stuck at 186. I can't get a single pound off (or on)
I grew frustrated and when the scale broke I chucked it and decided to go on photos to see the changes in my body.

Compare these to the ones I took back in January and I see a change for sure!
