how do animals that don’t have a heavy meat diet synthesize so much muscle mass?

Question

I’ve been watching Chimp Empire and the thought occurred that these chimp dudes don’t really eat much protein outside of like an occasional monkey. Even gorillas are also mostly eating plants from my understanding. How do these animals get so beefed meanwhile the average human bodybuilder has to eat a ridiculous amount of protein per day to bulk and put on muscle mass?

Answer 1

Gorillas are an especially fascinating answer to your question,
their highly specialized digestive system has bacteria that consume the plant fibers and produce protein.
