Addicted to the damn scale!
Not too long ago I had a response on my blog from someone claiming to be a trainer and that my stall was not necessary and was recommending changes I knew weren't beneficial--just to make the scale move. Believe me, the stall was frustrating. I was at 270 for mid-May to mid-June and then it broke and broke big. It took everything I had, plus a little whining to make it through.
There is no "this is how it should be". The math doesn't always play out, week after week smoothly and perfectly. When you accept that, you free yourself to just do the do. After almost a year, I've finally won back my sanity from the scale. Now I don't care what it says, when it says it. If I'm doing things right, that's all I need to know.
