I tried making low carb bread - flax, gluten, bran, etc. It was horrible - awful taste and consistency of a sponge.
For my husband I have been getting Oroweat, Light 100% Whole Wheat Bread. Two slices have 18 carb and 7 fiber = 11 carbs. One slice then has 5 1/2 carbs. The slices are small. I would rather have half of one of those small slices of real bread (about 2 1/2 to 3 carbs)than a slice of that sponge stuff which has about 3 carbs.
