Rather than use reduced calorie bread I have enjoyed thinner sliced or smaller loaves of regular bread. We like Dave's Killer Bread. Here in the Bay area there is also lots of local sourdough which is lower in fat and sugar and tasty.

I haven't noticed a huge taste difference, but most "reduced calorie" breads are also smaller slices that I tend to find less satisfying than normal bread. I agree with @myallforjcbill that sprouted wheat bread, like Dave's Killer Bread, is a great way to get a satisfying slice in for fewer cals and no artificial stuff.

I bake my own bread and just slice thinner slices. I also bake lean sourdough loaves that have no honey or oil, so they are just flour, water, yeast and salt.
