I'm a great proponent of the 'non-scale' victory.
You know the ones, like when your undies begin to fall down, or your pants are too big, or my personal favourite - needing to pull the drivers seat forward another notch, that sort of thing.
Non-scale victories are great for the confidence because you know you've been working out hard, and staying on track with your eating, but the blasted scales just aren't showing the results of all that effort.
