Fats are quite difficult for the body to break down. But carbs, especially sugars, are really easy to digest. If one eats a lot of fat, it may actually make its way out unchanged.*
*I’m not a nutritionist, I just drank 250ml of olive oil after loosing a bet.
Maybe a bit late, but the worst thing about it was the texture while drinking and… wiping… because oil really needs soap to come off.
But other than that, it was pretty uneventful. But I also have a pretty non-problematic stomach that rarely complains.
