Why CaloRec never counts your resting metabolism
Most calorie apps add the calories your body burns at rest, then subtract them again. CaloRec counts only active burn, and the number is more honest for it.
Open most calorie apps and the day starts with a big number already in your favour. Two thousand, sometimes more, before breakfast. That number is an estimate of your resting metabolism, the energy your body spends keeping warm and thinking, and the app has added it to your budget.
Then the app subtracts your meals from it, adds your workouts back, and shows you what is “left”. It feels generous. It is also the least certain number in the whole app, dressed up as the most certain.
One assumption, kept in one place
CaloRec takes a simpler line. The balance you see on Today is:
net = food in − active burn
Food in is what you said you ate, looked up in the nutrition table and confirmed with a portion chip. Active burn is what your watch or phone recorded you doing: a walk, a run, a workout. Nothing else.
Your resting metabolism is still in the picture, but in exactly one place: the plan. When you choose “Hold at 2,300” or say “I want to lose a little weight”, the target already assumes a resting burn for a person like you. Adding the same estimate into the daily ledger would count it twice, once as a target and once as a credit.
Why this makes the number calmer
A resting-burn estimate can be off by two or three hundred calories either way. Formulas disagree, and bodies disagree with the formulas. If that estimate is baked into “calories left”, the day’s number swings by that much before you have done anything.
Keeping it in the plan means the swing lives in one decision you made once, which you can change with a sentence, rather than in a figure that changes every time you look.
It also means the line under the hero number can be honest. “Room for a normal dinner, about 780” is a comparison of two things CaloRec can actually see: what you logged, and the target you picked.
What counts as active burn
- Walks and workouts your watch recorded, read from Apple Health or Health Connect.
- Runs you start in CaloRec on the phone or on the wrist.
- Anything you say out loud: “I walked for forty minutes” is an entry too.
One event becomes one entry. A run tracked by the watch and by the phone at the same time is written once, with a note that says so.
What this is not
CaloRec is not a metabolism calculator and does not try to be. It will not tell you your basal rate, your TDEE, or how many calories a flight of stairs is worth. It keeps a ledger of what went in, what you did on purpose, and how that compares to the plan you chose. The rest of the day’s energy is yours, uncounted, as it should be.
