There's kind of a growing movement around Rob Rhinehart's Soylent thing, dunno if you folks have heard of this.

Basically, he got tired of making food all the time and tried to figure out the absolute minimum required chemical compounds required for a healthy diet, and then posted the overall list, and has now been roughly food free for three months, along with a bunch of other people.

It seems awesome to me and I'm hoping this sort of idea becomes more prevalent. My favorite quote from him I can't now find, but it's something along the lines of "I enjoy going to the movie theater, but I don't particularly feel the need to go three times a day."

There's small reddit community/discourse groups around getting your own mixture.
