Can I do whatever workout I want on 50 bananas a day? My expectation is no. I think that I'll have the energy to do lots but not the protein to build and repair the muscle.
A lot of talk comes from people that aren't building muscle. Why are we all so skinny? Could it be because we are low fat and low protein? We are skinny because we don't get the building blocks to get bigger - I think that is flat out the case for most.
This does not mean eat animal products or cooked grains or beans or whatever, but I think it's worth pointing out that if we want to gain muscle mass we need to eat more. I don't see how we're going to build muscle on 33-38 grams of protein per day - even though that can be 3000 calories.
I don't see anyone doing it.
UPDATE March 2013
It has an interview with Charlie Abel a raw bodybuilder on the topic. And more interviews to come.
I've gained 20 pounds since starting this lifestyle, but definitely eat more than 40 grams of protein per day. I think that 50 grams should be enough for most people to gain significant muscle.
Check out this article I wrote:
It talks about the fact that a pound of muscle only contains around 115 grams of protein - which means to gain a pound of muscle you might need only eat around 4-5 grams of protein extra per day!
