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.
Smoothies with a proper dietary balance still have fiber. So yeah.
But even beyond that, waste products from the gut microbiome, and left over bits that the body doesn’t use. Best case scenario, you would have small, liquid poops.
Your best bet? Intravenous feeding. Not that Drag has any intention of doing this.
If the fiber is required for a proper diet, why isn’t it absorbed by the intestines?
