Answer 1

I guess it could be possible but not sustainable in “the wild” because meat is a lot more calorically dense than fruit and veggies. You’d have to spend a lot more time/energy to eat just plant matter. There’s a reason grizzlies bulk on salmon before hibernation and not just eat grass and berries you know 🤔
