How long to burn one serving
About 22,800 steps, or 177 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.

Where the numbers come from
This is a home-style dish, so there's no single lab value. We built it from USDA ingredients using this recipe, then divided by its total weight:
| Ingredient (USDA entry) | Grams |
|---|---|
| Pasta, cooked, enriched, without added salt | 200 |
| Cream, fluid, heavy whipping | 60 |
| Butter, without salt | 15 |
| Cheese, parmesan, grated | 25 |
The ±30% range reflects how much real recipes and portions differ: more oil, fattier meat or a bigger scoop all move it.
