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

Where do you think all the dead microorganisms from our GI tract go? Some bits are ‘recycled’ by their brethren, sure, but something is gonna be coming out when it’s all said and done.

Answer 2

Feces isn’t just food, it’s waste in general. So even without food and water, you’ll still shit until you die from starvation and dehydration.
