How long to burn one serving
About 1,900 steps, or 15 minutes of brisk walking for an average adult.
How we count: an adult of 75 kg and 175 cm walking at 5.6 km/h burns (4.3 − 1) × 75 = 247.5 kcal an hour above resting. Steps are distance divided by a stride of 0.415 × height. That's about 31 steps per kcal. The Kalorea app uses your own height and weight.
Fruit varies mostly by size. A small banana and a large one can differ by 60 kcal, so something for scale in the frame helps.
