Nutrition by weight
| Weight | Calories | Protein | Carbohydrate | Fat |
|---|---|---|---|---|
| 50 g | 77.5 | 6.3 g | 0.6 g | 5.3 g |
| 100 g | 155 | 12.6 g | 1.1 g | 10.6 g |
Values are scaled from the per-100-g data and rounded. “Calories” means kilocalories (kcal).
Tips for weighing and logging
A 50 g serving is an example, not a fixed weight for every egg. Exclude the shell.
To calculate manually, multiply your portion weight in grams by 155 and divide by 100. For example, 50 g provides approximately 77.5 kcal.
When logging a photo, check the food, cooking method and estimated portion before saving. A photograph cannot reliably show hidden oil or exact weight.
