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?

Answer 1

Simple answer: No it’s not possible. There’s a lot more going on than “food that our body couldn’t digest or use” going on. Even with “human optimized” foods like Soylent or its EU variant JimmyJoy you still have waste, with the addendum of making your stomach and intestinal tract lazy because you don’t eat solid foods making “going back” to real food an actual pain.
