What a calorie counter is for
A calorie counter is a record of what you eat in a day, scored against a target. The target depends on your weight, your activity, and what you want to do next, whether that is losing fat, holding steady, or building muscle. The tool itself does not change anything. The act of writing down a plate is what changes the next plate.
Used well, a calorie counter answers two questions. How much am I eating in a day, and what does that look like on a plate. After a couple of weeks the numbers stop being a surprise. Most people can stop logging at that point, or drop to logging only one meal a day to keep the calibration honest.
We are not interested in the parts of this category that lean on guilt, on streaks, or on bright red warnings. A calorie counter is a notebook. It works when it disappears into your day, not when it shouts at you.
