There is a small but growing community of people who eat only raw fruits and raw vegetables. I tried it and it was awesome (though it was expensive and I had trouble getting quality produce).

I find this community very knowledgeable, smart and down to earth. It was impressive to see a 40+ year old body builder (he is no Arnold, but has impressive physique for an amateur) doing so well on this diet.

If someone is interested, spend some time googling this topic. It is well worth your time.
