If you ask most people, they will tell you that it is impossible to build a decent huge body without eating meat. Most big bodybuilders are fans of meat, especially red meat as it has Creatine and other needed amino acids in it and they consume vast amounts of meat.
Can you build a BEEFY body without beef? By being vegan for example? Well, apparently so and you can even go all the way to winning a Mr Universe contest too as Barny Du Plessis did at the 2014 NABBA Mr Universe! There go all the theories on only meat eaters can get huge!
What you need to bear in mind though is that these vegan bodybuilders do consume a huge amount of vegan protein and they ensure their protein intake is kept high through vegan sources. At the end of the day it is protein that will build decent muscle size (and keep it) and if you are not getting it from meat, you need to get it from vegan sources - a lot of them!
