Yeah, just don't go overboard on them. Don't sit down and eat a whole bag or two... having a normal sized portion or two in a sitting won't make you "act up" and ooze uncontrollably (sorry, had to throw that in). The thing is that the olestra just isn't metabolized by your body, so it has to come out one way or another. If there is a lot of it in your GI track, it will cause loose stools.
