Thanks for this response.I eat lots of psuedograins and beans, so I haven't done a frutarian diet and I do get protein. I feel great, so I stand by a low-fat vegan diet (for me). I came hear with questions about what the fruit situation would have been like in primitive times. By more vascular, I mean more pumped then on low-carb...most people find that happens. Don't eat more animals just because I'm not eating any.
