Consistently, I eat great during the day and then bust out the calories during the evening. I don't know why I can't keep track during dinner, but I keep eating even after I finish the meal I've planned for myself. In my mind it's something small, but I shouldn't overeat by even 100 calories.
I need to plan my dinners better. When I don't plan my meals, I don't eat well. Which is what makes the holiday season so hard. Or, you know, life.
