How long to burn one serving
About 10,900 steps, or 85 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.
Shoot it from above so the whole plate is in frame. If it's oilier than usual, add “lots of oil” to the description, and Kalorea will lean to the top of the range.
