Bread, sugar and potatoes exist on a spectrum from highly processed/refined (truly problematic) to minimally processed whole food versions (nutritionally valuable). There's no reason to give up minimally processed whole food versions of these.

What a bizarre, illogical comment. Did you even read what @throwawaylaptop wrote above? While most of us can handle she carbs just fine, some people have to pretty much eliminate them (regardless of processing level) in order to lose fat.

There is no spectrum for me. I can't eat bread or sugar.
