How long to burn one serving
About 8,800 steps, or 69 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.
Cooking method matters more than the cut you see. Frying in oil or a creamy sauce can add 100 kcal or more, so mention it in the description.
