Tips for weighing and logging
Weigh butter added to bread or rice and include it in that meal.
To calculate manually, multiply your portion weight in grams by 717 and divide by 100. For example, 10 g provides approximately 71.7 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.
