ELI5 Why didn't humans develop the ability to store protein?

Since our ancestors relied on hunting to survive (before learning how to farm etc) and there wasn't a prey to hunt Everytime they would've benefited from being able to store protein to keep their muscles so that they can hunt effectively right? So why didn't we?

Muscle mass doesn't help you hunt. Look at any hunter gatherers around the world and they're all very slight and built for long range endurance not raw strength. Cleverness makes you a good hunter and our brains require a tremendous amount of energy to function properly, and the most efficient form of stored biological energy is in the form of fats, which is why our bodies pack on fat, rather than muscle. In fact, muscles are very hard to maintain from a physiological and dietary stand point. Just ask anyone who stopped going to the gym for a month, or more.
