Why though? He didn't say that "Given that ALL/MOST top body builders are vegans", but that "Given that top body builders are vegans".

And indeed there are some. Which points that there's no necessary connection between being vegan and losing muscle.

He also didn't say "Given that SOME top body builders are vegans".

Top body builders eat meat. Top body builders do not eat meat.

The implication is "The top body builders", but yes, there's wiggle room for when someone challenges the statement.

It would be seriously cool, though, if anyone here could leave a link as a citation to any article, tweet, FB page, whatevs that shows even one top body builder who is vegan as back up for the claim.

Because Google is too difficult? (note to self: cut down snark)...
