I was a lifter, with some nice results, after just one year in a "healthy" cooked food diet. I wasnt into junk, but i was a omnivore.
I have being doing 811 for 4 years and a half now. Its unbelivable in terms of health results. I wish i could go back and eat a high protein diet, because i enjoyed the looks and getting every month bigger and bigger muscles, but my body wont let me. I fell so good and am so much more productive eating this way. But unfortunaly, i disagree with doug, that affirms that less then 10% protein is enough.
For this 4 years and a half, i kept lifting at least 3 times a week, but no improvements. No losses, but no improvements as well. And i look smaller then ever, had my own face and body look that i had at 16, and i am now 27. I rejuvenated and look like a kid

. Its good to know and even see that i will live a lot longer, but for sure, hehehe i digged the old look because girls dig a lot, a more muscular and "men" looking body.
It has its pros and cons. I am still trying to figure out ways to get bigger and still be raw and a frugivore... but if i had to drop my raw fruit and veggie diet for muscles, i have to say i would prefer to be a small thin guy as i am today.
