Look at the graph in my signature, below.
The lighter line is a trend line calculated automatically, based on all those ups and downs. But one thing that may not be obvious is that some of those ups that are more recent are equal to the downs from a month ago or more.
Weight fluctuates a lot. I understand that it's nice to see a change on the scale, and it can make you feel motivated about continuing... But you can find other ways to track your progress, so the number on the scale isn't everything.
I love data, and I am collecting as much of it as I can as I lose weight. But I'm not rewarding myself or judging my progress based on the scale, because I'd be disappointed in myself too often, for something I don't have much control over. So instead, I reward myself just for logging my calories regularly. By judging my progress based on how well I stick to the plan, I'm giving myself realistic and achievable goals. I have complete control over what I eat and whether I log my calories (that is not to say I don't overeat sometimes, but I know it was a decision if I do, since I always log my calories and stay aware of this).
I still pay attention to my weight because, of course, I need to know which way it is trending so I can adjust my plan accordingly. As long as I reevaluate regularly though, I do not need to use my weight as a direct guide for how well I am doing. Sticking to the plan is good enough.
My method might not work for you. But I want you to know, it's possible to like your scale, and not rely on it to tell you how you feel.
