Thanks for that, very interesting. There used to be some fruitarian who said his bloodwork was all perfect eating primarily some ridiculous number of bananas each day. And his conclusion everyone should just eat fruit. Well he was burning over 10000 calories a day bicycling, I think he was a delivery rider and it was his hobby. That diet doesn't scale down to 2000 calories for the reasons you mention. I also wonder about all that potassium...
