A 45-minute walk counts. In CalorAI, you can log it and see roughly what it burned.
The calculation
Each exercise has a MET value, a standard measure of how hard an activity is compared with resting. CalorAI subtracts 1 MET, so you only count the calories above what you would burn anyway:
(MET − 1) × intensity × 3.5 × weight in kg ÷ 200 × minutes
Intensity is 0.75 for low, 1 for medium and 1.25 for high.
Examples for a 70 kg person
| Workout | Time | Estimated burn |
|---|---|---|
| Walking, medium | 45 min | 138 kcal |
| Walking, low | 45 min | 103 kcal |
| Weights, medium | 60 min | 184 kcal |
| Running, medium | 30 min | 323 kcal |
What happens to those calories
Burned calories are added to that day's target. If your target is 2,000 kcal and you log a 138 kcal walk, your target for the day becomes 2,138 kcal.
Don't overcount
These numbers are estimates. Heart rate, fitness and effort all change the true figure. If you want to lose weight, it is safer not to eat back every calorie you burn.
