The protein leverage hypothesis suggests that animals consume enough protein to optimize their genetic fitness, which is distinct from maximizing lifespan.

“And Steve Simpson and David Robenheimer from down under from Australia uh study something called the protein leverage hypothesis we may want to come back to at some point. And what what they've shown is that what at least some animals do in experimental settings they're able to set up is they consume enough protein to optimize their genetic fitness. Meaning how many of their genes they trans they're able to transmit to the next generation, which is if you want to win the evolutionary game, that's your goal. Um, which is different than living a lot longer, right?”
