The locust infestation we're about to have is low fat, zero carbs, and high in protein.

Get ready to put on the feed bag and dig in.

I wonder how good they are as a source of fiber and potassium.

It's a pity that they're available so rarely -- the diversity of cuisine possibilities described in the article is only a hint of what might emerge with a regularly-harvestable supply. Of course, there is a more plentiful alternative, harvestable 24/7/365 in many parts of the country: {http://tolweb.org/tree?group=Blattaria&contgroup=Dictyoptera}...I imagine marketing them as a food source would be something of a challenge, though.
