Imagine the side effects of food passing through the gut without being broken down. Reminds me of Olestra, the zero calorie oil substitute that failed because of similar sounding side effects. Olestra wasn't consumed/absorbed in the gut so you'd just shit out oil and your half digested food would glide out with it since it didn't block stomach emptying like real food.
