I often hear that vegan athletes cannot perform at the same level as non-vegan athletes, focused more in terms of strength, performance, etc.

There are tons of articles and debates on the topic.

But is there a real study or good examples that support this?

And, if any, what are the pros/cons for athletes on becoming vegan/vegetarian?

  • In what way? If the premise of your question is "there is tons of arguments and debates", it is already too broad to answer in this context. But if you have a very specific question about a particular aspect of how a vegan diet might affect the body, it might work here; but this is simply too broad to answer decisively in the one-answer Q&A style of this site.

  • is there a real study or good examples that support this? so, no @RobertCartaino, I'm looking for studies and facts, I don't want more debate as there is enough already on the internet Feb 3 '17 at 14:23
  • About what though? There's no real "problem statement" here that can be answered definitively in the context of this site. "Performance" can mean anything; the field of athletes covers a lot of territory. We could list literally thousands of anecdotes about performance improvements here they'd all be equally valid. That's why broad questions generating a scattershot of random answers for your to pick through later are not really how this site was meant to work.
