Just wanted to address the "why does fruit have so many carbs?" question.
I would lay money on the fact that commercially available fruit is larger and sweeter than the wild fruit Grok ate. Most wild blackberries in my yard are about half the size of the ones in the store (though there are a few that get that big---just not most of them). Wild strawberries (which are mind blowingly delicious) are less than 1/5 the size of an average commercial strawberry. A bag of Trader Joes wild blueberries contains fruit at least 1/2 the size of farmed, non-organic blueberries.
