1. Everybody is different, and there is no set “normal” when it comes to passing stools. That said, the normal range spans three times a day to once every three days, meaning the average person poops approximately once a day —about 1 ounce of stool for each 12 pounds of her or his body weight.That means a person weighing 160 pounds produces an average of just under a pound of poop each day.n contrast, sloths go only about once a week. Poop and poop habits are pretty varied in the non-human animal world, and the same is true for people. Despite being a universal act, this part of “going to the bathroom” is rarely discussed.
