Still N=1 but at least it’s not just ‘feeling’ clearer: I can complete cryptic crosswords by particular setters when eating a keto diet. I couldn’t do this before. Did I just get better at them? I’ve had two switches back to non-keto for a few weeks each and during both I could hardly start the crosswords. I also ‘know’ I am much more able to focus and prioritise better in my work, but there is no quantitive measure I can use there.
