Go and have a look at the amino acid profiles of seitan and tofu and also their bioavailability in comparison to meat and vegetarian protein sources. And you can talk all you want about people overestimating protein macro but 1 to 2 grams per lb of bodyweight has consistently shown to be optimal. You’ll be hard pressed to find any high performing athlete who isn’t aiming for that outside of endurance sports.

At the end of the day in my experience, a vegan diet is both a lot more hard work and less healthy than a non vegan one. Saying that a vegan diet isn’t any less healthy than a meat eating or vegetarian one is an absolute joke, especially considering there are no vegan foods containing vitamin B12 outside of yeast flakes and artificial supplements.
