I use a scale and weigh in every day. My daughter and I totally disagree on this. It all depends on your mind set. If I weigh too much, I tell myself it is a reminder to watch what I eat today. If I’m losing, I tell myself awesome job and take heart. If I weigh the same I tell myself maintenance is golden, keep up the good work. My daughter however sees a weight loss and goes out and eats something to celebrate. If she gains weight she tells herself its all a waste of time and goes to the refrigerator and eats . . . you see the pattern. She is not a scale person. It is not her friend.
Its all how you look at the scale. Also remember its going to bounce up and down as your body does its daily thing. Have some rules. I weigh in the same time every day (am) and wear the same thing (jammies) and even though I weigh daily, I always look at the WEEK’s pattern (upward or downward). I think scales are a good thing.
