Question: how much weight can you lose if you poop?
Answer: You can lose weight from pooping, but it's very, very slight. “Most stool weighs about 100 grams or 0.25 pounds. This can vary based on a person's size and bathroom frequency. That said, poop is made up of about 75% water, so going to the bathroom gives off a little bit of water weight,” says Natalie Rizzo, MS, RD.
