I’ve heard it repeated multiple times that carnivore-dieters have very few and small bowel movements because of this alleged fact.
Plant based foods contain a lot of bulking and indigestible parts (fibre, resistant starch etc) which bulk out stool, and help keep things working smoothly.
Meat doesn’t, so yes. It’s not really a good thing, though. Or really that negative barring constipation.
A balanced diet is usually better. Humans are meant to poop 2-3 times a day.
As an ileostomate I can confirm meat is generally fully emulsified when exiting. Absorption? I can’t really answer that. My blood numbers look solid though. I assume food that is fully broke down when exiting ileum has been more readily absorbed. Animal products are a staple of my diet because they break down a lot easier and generally less distress. Insoluble fiber and sugar are problematic for myself, usually causing more gas to form and watery discharge. With a colon there are benefits to the insoluble fiber as it helps with stool formation. So maybe it’s finding that balance that works for you.
