One of the things I've been up to the last couple years is reducing the divergence between my life and the conditions I probably evolved for. E.g., much less processed food, reduced use of artificial light that diverges from the normal day/night cycle, more frequent modest physical exercise, very low sugar consumption, way less alcohol and caffeine. To me it feels a lot like when I'm debugging a system and am trying to get back to a baseline by eliminating complicating factors.

Lately I've been wondering about fasting in that context. Not eating occasionally was presumably pretty normal for our ancestors. Have other self-hackers here experimented with this?
