Tips for weighing and logging
Weigh after peeling. Log accompanying milk or nut butter separately.
To calculate manually, multiply your portion weight in grams by 89 and divide by 100. For example, 100 g provides approximately 89 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.
