Assume the smoothies have the same nutrient profile as a regular diet. Like if you drank runny mashed potatoes and protein powder to simulate a normal food intake.
If you do poop because of the nutrients, is there a healthy diet at which waste products are no longer left in the intestine to turn into poop?
Drag has no intention of doing this, drag is just curious about the science.
Yes. But it would be the same consistency coming out as it went in eventually. Unless your body uses 100% of what goes in, you’ll always poop. And since you can’t absorb 100% of what you take in, even if you only take in what you need, you will never not poop unless you stop eating entirely. And you wouldn’t not poop while alive very long until you’re not pooping while dead.
