I find this incredibly fascinating. Especially the ability to save hours every day from not needing to eat. If the guy doesn't die after a year or so, I'm definitely trying this out.
When I looked at his blog last, he was eating out socially (understandable). So we onlookers won't get to enjoy his discovery of any new micro-nutrient deficiency syndromes.
I wasn't especially impressed by his approach. Maybe he'll get some good advice from others, but I didn't think he was anyone to listen to.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
