Tips for weighing and logging
Weigh the kernels used in a recipe or breakfast; halves are not all the same size.
To calculate manually, multiply your portion weight in grams by 654 and divide by 100. For example, 30 g provides approximately 196.2 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.
