Anyone who's worked out on a regular basis can confirm this. And it's not just anecdotal, significant components such as creatine simply don't exist in vegan meals without supplements.
As an ex-vegetarian (who rarely eats meat now), I'd love to see more research into this and what's missing. Also, what needs to be done to supplement a vegan/vegetarian diet for exercise is pretty well known.
But this "study" of a small sample size confirms what has been pretty much completely and unambiguously known for decades. And it's meat industry funded. Nice.
