How long to burn one serving
About 6,800 steps, or 53 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.
Size is what changes the number here. Put something for scale next to it, like a fork or your hand, or type the weight if you know it.
