A study by a pill manufacturer whose business is sickness, promoting a sick diet for more obedient consumer customers.

Adult humans require surprisingly little protein. So little, in fact, it's virtually impossible to be protein deficient eating an adequate isocaloric diet with even a modicum of variety. This is a very well cited page which explains most misconceptions and falsehoods about protein in diet https://www.drmcdougall.com/misc/2007nl/apr/protein.htm

McDougall promotes a vegan fad diet. Not sure why I would trust his literature when there's plenty of contrary scientific evidence today. Also, it's been 16 years since that article was written. Scientific consensus has advanced considerably.

Just because humans survive on very little protein doesn't mean there are not negative implications, notably on muscle mass and development.

Fad diet? Until recent history, and coincidentally before the prevalence of vast diet-related disease, most of the world lived on a mostly vegan diet. You are welcome to cite some of this advanced scientific evidence refuting McDougall or suggesting protein deficiency is a concern anywhere in the Western world.

You're confusing requirements vs thriving. Yeah humans can essentially starve themselves for months and survive, that doesn't mean it's optimal.

You miss the point: reducing protein intake to the small required amount is what is optimal for health.
