I've heard that before, SparkleKitty - about obsessive tracking.
It seems that the people who struggle with it the most are usually restricters. I am a binge eater, so tracking is a very good thing - because if left to my own desires/appetite, I would eat 4000 calories per day every day; and I only need 1700-2000. It's hard for me to start and stop eating. I don't have an off button for alcohol, and I often can't seem to find it with food, either. Once I start eating for the day I do better when I have a large amount of protein and few carbs first thing or first meal. That slows my appetite down.
I use a digital food scale and make almost all my meals from scratch to control the ingredients so there is a bit of controlling behavior going on, but it's good control!
I don't think of it as obsessive, just what I need to do to stay on plan.
