I'm interested in cognition-enhancement as well as life-extension and there's a lot of anecdotal claims of increased mental sharpness on a ketotic diet, where the brain and body are powered largely from "ketone bodies" derived from fats, rather than glucose/glycogen stores.
(The ketotic diet has some other health benefits as well, but many of those seem to be largely duplicative with CR.)
Is anyone in this community doing a "ketotic version" of CR? (High fat, low/medium protein, extremely low carb.)
I'd be very interested to hear your experiences -- although admittedly, I hate the idea of giving up fruit.

PS: These forums seem oddly quiet. I read somewhere that there are about 10,000 CR practicioners -- is there someplace other than this website where people are hanging out online?
