a bunny diet would almost kill us. There isn’t enough nutrients to sustain ourselves and we are omnivores. Meat increases out life span (look at specific african tribes that eat meat vs Vegetarians, HUGE difference between quality of life). We probably could eat more treats but that would be the only fat and sugar we would get. Rabbits are mainly muscle, very little fat. hypothetically let’s say humans and rabbits were the same size, Humans would have much more fat, much different needs and would need a lot more nutrients to sustain ourselves. Not to mention the amount of fiber we would be eating would clog us up. Think for the shoe box example:
You have lots of shoe boxes that you want to fit into a closet. Would you put them in empty? No because then how would you’re shoes fit in the closet as well. You’d put the shoes in the box and then in the closet. They same thing applies to fiber. If you put in just fiber, you fill up the stomach with no room left for nutrients. If you eat More nutrients than to a box of fiber you’ll fill up faster and more efficiently. However if we were eating the amount of fiber a bunny eats, we would have a lot of empty boxes in our closets, take up unnecessary space and not have enough nutrients. That would kill us, not to mention we can’t process fiber the way rabbits do.
So TL;DR
No we could not survive on a bunny diet, but if we could we would be eating a lot more treats.
