Tips for weighing and logging
Check the packing liquid, product label and drained weight.
To calculate manually, multiply your portion weight in grams by 86 and divide by 100. For example, 100 g provides approximately 86 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.
