When I stop weighing myself, my weight goes up. Believe me, this has happened a few times. I do go by the fit of my pants and some of them are a bit tight. At first I thought it was because I had just washed my jeans, but it's all my jeans and pants. Of course my huge cycling calves and quads don't help here. I like those things, but when the hips of my pants get tight, that is a cue.
I bought new black ankle length pants in the smaller of the 2 sizes I wear, because the reviews said they stretch out (this brand does). They are really tight, but I am wearing them now to remind myself not to over eat tonight.
