Great and informative post. One thing though that I don't quite agree on though is the bit on protein. Rather than referring to it as too much protein, I'dd prefer to refer to it as not enough resistance training. My previous issues with keto were basically all related to losing the wrong kind of weight, lean body mass, and losing it for two reasons. Reason one you address in your post, ofcause was not getting enough salt. The second reason however was that my protein intake wasn't suficient to fully sustain my muscle mass. I know lots of people don't care that much about losing LBM as long as they are losing weight and have a shrinking weist circumverence, not losing any LBM in the process IMHO is still the prefered way to lose fat, and high (at least 1.0 g/kg LBM) protein combined with a solid weight lifting regime seems to be the best way to do that. Thus my conclusion that the more common mistake is actual a lack of resistance training rather than actually consuming too much protein.
