What changes the calories
- Slice thickness varies a lot between loaves, so a thick bakery slice can carry noticeably more calories than a thin pre-sliced one.
- Spreads like butter, cream cheese or mayonnaise add their own calories on top of the bread, often more than people expect.
- Recipes differ: some rye breads are blended with wheat flour, seeds or sweeteners such as molasses, which can shift the calories and macros.
- Toasting removes some water, so a toasted slice weighs less but has about the same calories as it did before toasting.
Tips for logging it accurately
- Weigh a slice once on a kitchen scale to learn whether your loaf's slices are closer to the 25 g thin slice or the 32 g regular slice.
- Log spreads and toppings as separate entries so the bread's calories and the extras are both counted.
- In BerryFit, you can snap a photo of your sandwich or toast to log it, then adjust the slice size to match what you actually ate.
