Will you elaborate on the obvious reasons? Pretend they aren't obvious to me.

I'm interested in reading more about athletic advantages gained from consuming meat. Is there a reason that other sources of protein aren't giving the same benefit?

I assume they mean efficiency as in land area used etc. You have to put quite a lot of calories into a cow to get one calorie out.

seeing as how veganism is not the default choice in most of the industrialized world, this is a misleading frame. it's also incorrect that it's more efficient to "eat animals" to produce muscle if we're being pedantic (as a vegetarian, however, this is not a meaningless distinction to me)— amino acids in dairy & eggs have a measurably higher bioavailability than those in meat, whether ranked by the PDCAAS or DIAAS https://web.archive.org/web/20151010170125/http://www.idf-is....
