Whole Wheat Bread calories & macros
254 calories per 100 g · 81 calories per 1 slice (32 g). Whole Wheat Bread (commercially prepared).
A slice of whole wheat bread is about 81 calories with roughly 2 g of fiber — around three times the fiber of white bread, and the main reason to choose it. Slice weight varies a lot between brands, from thin sandwich slices near 25 g to bakery cuts over 45 g, so the per-slice figure is a guide rather than a constant. Check the label: many loaves marketed as 'wheat' or 'multigrain' are mostly refined flour with colouring.
