Many trackers work like this: jog for half an hour — here's +300 kcal in your budget, "you've earned it". It looks motivating, but in practice this exact mechanic is what stalls progress most often. We don't do it on principle.
Why "earned calories" don't work
First, burned-calorie numbers are inflated. Study after study shows fitness watches overestimate activity expenditure by 20–40% — even the best ones. "+300 kcal for a workout" on the screen is more like +180–240 in reality.
Second, your body compensates. After a workout you unconsciously move less for the rest of the day, and appetite goes up. The real increase in daily expenditure is almost always smaller than the workout's number — the body is good at saving energy.
Together these two errors add up to a familiar story: a person trains honestly, eats back what they "earned" — and the scale doesn't move. It's the most common complaint from users of trackers with this mechanic.
How Calorize does it instead
- Your daily goal already includes your activity. The activity coefficient you picked bakes your usual movement into the goal. Crediting the same workout twice would be double counting.
- Mira sees your activity as context. In the daily and weekly analysis she'll account for your strength session or an active day: she'll support you, remind you about protein or warn against cutting food too hard — but she won't "give calories back" into your budget.
- The same applies to watches and health apps. Even when Calorize can see your steps or workouts from a watch, they never turn into extra food in your budget — only into smarter analysis.
What if I genuinely train more now?
If your activity has changed for good — you started going to the gym regularly, or you're training for a race — there's one honest path: update your activity coefficient or calorie goal on the Personal page. Your goal rises for every day at once, stable, with no daily lottery of watch numbers.
And remember: a workout is not a way to "work off" food. It's sleep, mood, muscle and health. Food is one thing, movement is another — and you're in charge of both.
If you connect steps and workouts from your phone or watch — see Syncing with Apple Health and Health Connect: that activity also feeds only the analysis context, never your calorie budget.
