Ha. Nice. What is interesting about that scenario is the human would be loading up on protein (probably meat based diet) and working hard to gain that, and the gorillas sit around eating a vegetarian diet and have massive muscle mass just because.

gorillas sit around eating a vegetarian diet and have massive muscle mass just because they metabolize different kinds of protein MUCH more effectively than humans do and also are much more physically active than the average human

Fixed it for you.

This would, of course, change if said gorilla had to sit at a desk for 40 hours a week.

Definitely a little but, but probably not as much as you’d think.

Humans produce a protein that forcibly limits our muscle growth and its impact is kinda crazy. Gorillas produce a bit of it too, but it’s a drastically lower amount. It’s called myostatin if I remember right, there is a dog that sometimes has a mutation where they barely produce it too and the differences between a regular one and a mutated one is pretty extreme. Look into ‘Bully Whippets’ if you want some interesting reads.
