I swear, I think the scale should KNOW how much effort it took to stay on plan and darn it, it should compensate me for that effort. But unfortuately, scales are just dumb machines.
When I first started, I had a month where that happened and so I started recording my food and I found out that I was going over my goal. Oops! So, make sure it's not that first.
Then, check out those leg muscles, arm muscle and anything else you're working. Is your butt smaller? Are you muscle bigger?
This would be a good time to start making a monthly measurement of yourself, so if the scale doesn't move, maybe the tape measure will!
Hang in there, chica! I know how much this hurts!
