What is your n=1 methodology? Plenty of logged data, or occasional intuitive insights? I would be really interested!
Edited To Add: How do you structure your self experiments?
I tend to single out what I want to change/improve/solve clearly first, then read any scientific literature I can find that's related to it. If information is unsatisfactory I end up trawling the blogs and PaleoHacks for ideas on what to try. Then I pick one based on how simple it is to obtain whatever is necessary. I test it for as long as those who recommended it and note my results. I then stop the intervention to check if that has any effect, then I start up again. I'll often retest somethings years later again, or with different variations. Probably the only things I don't test anymore is getting enough fat, avoiding grains and I have to avoid dairy.
The eating fat and avoiding dairy I started before coming across paleo. That's when I stopped grains.
