Today marks 3 months since I last had animal products. I actually started the "Shred It!" challenge on Sept. 3rd, but had chicken on Sept. 6th. Ever since then, I've had no animal products. The purpose of this challenge is to build muscle as a plant based eater, rather than load up my body with too much protein that other bodybuilders do.
I didn't want the health problems that other weight lifters get.. kidney or liver damage from too much protein. Robert Cheeke's book proved that all that extra protein was not needed and that muscle growth can happen with just plants.
