New people introduced to eating wild edibles presume they can live off them, when the whole reason agriculture began 10,000-12,000 years ago was you were lucky to barely survive in tiny groups as hunter-gatherers. That only worked in history as so few in a group existed and the herds migrated and were abundant. It also means premature death by the very young and very old, and most likely in winter starving time.

An expert in summer and autumn when these seasonal plants are abundant might get 800-1000 calories but you need 2000, thus starvation is inevitable. Realize that most game is very lean and you can't absorb excess protein unless you are a bodybuilder whose biochemistry changes as they are exercising muscles intensely.

YOU MUST EAT FAT when starving. That is the historical way to survive. Some people were lucky as the fish around them were loaded with fat. But that has its own issues as that makes for fatty stools. That is ordinarily a peculiar medical condition except for certain indigenous people.
