If you had to replace our diet with the diet of a different animal

Polar bear. Predators are awesome and i could maul people to death.

He said diet, not laws (nor insane claws, size and strength). xD

I mean, if our taste buds were to adapt, I'd be all over the rabbit/sheep/cow kinda diet. Grass. It's not like the world is lacking in that department.

Alternatively: Ants, flies and cockroaches. They eat pretty much anything and everything, right? And don't need much to survive? That'll do me nicely.

They don't need a small amount of food because of what they eat, but because of their own size. You're getting their diet, not their daily energy requirements. You'd have to eat like a bucket of trash a day.

Me going for a bear's diet doesn't mean I suddenly have to eat 20 pounds of food a day either

A bovine diet isn't a terrible idea, although they do have to eat a pretty huge amount of grass, and not all sorts of grass are equally tasty to them either.You have to account for the availability of grass in certain seasons, but luckily cows can eat potatoes or certain types of fruit too. Not sure of they get as much nutrition out of that as we do, however, as their digestive systems are optimized for cellulose rather than fructose and starch.

I guess if it wasn't for all the ink on newspaper and such, you could safely eat that for nutrition during winters.
