I believe it does. When people get high colonics (enemas that go way, way up there) they can lose 15 or 20 pounds of poop (sorry, this is gross.) Apparently actors/actresses/models frequently get high colonics before photo shoots and award shows.

That's why some folks take laxatives - abuse them - because they get rid of an actual solid substance in your body that has weight and takes up space. If you're eating every day, and nothing's coming out, it's still taking up space.

If I don't go in a week or so, I won't lose the pound or two I expected. So I just take two or three psyllium seed husk capsules a day so I won't get bloated and cranky.
