Whole Food diet/Fruitarian

Anyone eat only whole foods or have a diet strictly made up of fruits?  I come from a Vegetarian background and hardly consumed any dairy products.  With that being said I just started(about a week or two ago) consuming higher amounts of whole foods and limiting my intake of man made foods.  Lots of veggies, fruits, nuts, grains, etc.  I feel great so far, and feel that I have a lot more energy.  I just started reading about Fruitarian based living and I am really interested with this idea.  My question is do any of you have experience with either a whole food based diet or strictly a fruit based diet?  I discovered Fruitarian living from this guys blog, pretty interesting stuff.  Just thought I'd share.
