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

Like others have pointed out, your feces are 60% dead bacteria.

The rest is a mixture of indigestible fiber, water and waste materials resulting from cell renewal and other biological processes. The indigestible fiber is actually healthy for you, it gives your feces bulk, unless you want to poop like a baby for the rest of your life.

You can’t live without producing any waste.
