Eggs absorb oil quickly when scrambled, so this dish moves a lot with the oil level.
With and without oil
The same 1 serving, changing only the oil the eggs are scrambled in. Normal is about 10 g in this portion. A little halves the recipe’s fat and a lot doubles it, so in a portion of the same weight a lot comes out a little under double. These are the four levels the app asks about, with the same numbers.
| Oil | Added | Calories | Protein |
|---|---|---|---|
| None | 0 g | 200 kcal | 15 g |
| A little | 5 g | 240 kcal | 14 g |
| Normal | 10 g | 280 kcal | 14 g |
| A lot | 19 g | 350 kcal | 14 g |

The recipe behind these numbers
Raw ingredient weights in one 1 serving, scaled from the batch recipe in the Homekcal app’s dish table, with normal oil. Water, salt and spices add almost no energy but are listed so the recipe is complete. If your version has more of something, the numbers move with it.

How this was worked out
This is the same dish the Homekcal app logs, from the same table. Each raw ingredient’s weight is multiplied by its per-100 g values in USDA FoodData Central, the batch is added up and divided by the cooked weight it makes. Calories are rounded to the nearest 10 and grams to the nearest gram, because a standard recipe is not your recipe. These are calculated values, not weighed or lab tested meals, and home versions vary a lot.
