A carnivore’s intestines are only about 6 feet long, because meat isn’t meant to hang out in the gut forever. Our intestines are 20 feet long; when we eat meat, it takes a full 72 hours to pass through us. That’s 3 days, and your bod , my friend, is 98.6 degrees inside! It’s like having a steak sit out in the hot sun for 3 days straight. Eventually it will start to rot and putrefy. And that’s what’s happening inside of you.
