It is 11 PM. You are standing in the kitchen. You are about to eat something you did not plan to eat.
And the little voice says: "I will not log this one. It does not count if it is not written down."
That voice is how people end up with a food log that is 100 percent accurate for breakfast and lunch and silent after dark. Which makes it useless, because the nights are where the story is.
So here is the rule. If you ate it, it counts, and it gets logged.
Not so you can feel bad. So the record is true. A true record of a rough night is more valuable than a clean record that lies.
