I could see where fiber comes into play, as that can help. Otherwise, I don't see any other carb being a good idea.

I’m not convinced fiber is all that important if you don’t eat processed junk. And sure, this doesn’t apply to everyone, but for a lot of people carbs help keep sex hormones in a healthy range, make it easier to absorb minerals like sodium, send the body a “plenty of fuel” signal that keeps stress hormones in check, and boost athletic performance.
These issues become more apparent after eating this way for a prolonged period of time.
