What changes the calories
- Slice size varies a lot between loaves, so a thin 20 g slice has 53 calories while a large 30 g slice has 80.
- Toasting removes some water, so a slice weighs a little less afterward but keeps essentially the same calories.
- Spreads such as butter, margarine, jam or peanut butter can add as many calories as the bread itself or more.
- Bread for sandwiches and toast is often eaten two slices at a time, which doubles the count compared with a single slice.
Tips for logging it accurately
- Weigh a slice from your usual loaf once, since packaged bread slices differ in thickness and weight from brand to brand.
- Log the bread and each spread or topping as separate entries so nothing gets missed.
- In BerryFit, snap a photo of your toast or sandwich and adjust the slice count and toppings so the entry matches what you ate.
