Tips for weighing and logging
Log added butter and cream separately.
To calculate manually, multiply your portion weight in grams by 22 and divide by 100. For example, 100 g provides approximately 22 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.
