If feces is the bits of food that our body couldn’t digest or use, is it possible to eat a diet that our bodies can use 100% and never have to defecate? And, if so, could such a diet ever be healthy or would it always be deficient in some nutrients?

It always perplexes me when people claim that meat is difficult to digest, in the context of “I’m not feeling well, I’ll eat oatmeal instead”. It’s actually quite the opposite. If you ate nothing but meat you’ll still defecate, but your body is so efficient at digesting it, there’s much less waste and you’ll only go every few days. And no, it isn’t constipation.
