Hi. I've been on Fitday since 2007, but just noticed this forum...ha.
I weigh myself most days. Depending on what I'm doing, I might miss a day or 2. Sometimes if I know it's going to be higher...I skip that day in order to give myself time to lose it
If the scale goes up, I am motivated to lose it, if it goes down, that makes me motivated to continue what I'm doing.
Sometimes waiting a week to weigh in can cause a 4 lb gain. So I like to stay on top of it.
