It's hard to really appreciate how many calories are added to things like bread, just by virtue of changing the recipe to be more "USA tasty" (e.g., sugary). My EU friends always commented on how sweet everything is in USA, even store-bought bread. If we didn't do that, when we started reducing fat, everything would taste like hardtack. But 200 extra sneaky calories a day + insulin spikes from the refined carbs, and here we are - all fat.
That's true, "bread" in the US is atrocious. I recommend flour, water, salt, yeast. Amazing book if you want to get into home baking.
