If you bite it, write it!
When tracking your food, be honest with yourself. Don't "tweak" the amount you ate to make it fit into your calorie range -- you will only hurt yourself. If you don't want others to know what you ate, you can always set it so no one can see your food tracker.
If you did go over your calorie range, commit to yourself to stay on the low end of your calorie range the next two days (calorie cycling).
