Going to add to the chorus here. One of the reasons these things are so successful is that it kind of kills the crave factor of eating. You don't get that feeling where you feel like you want to keep eating something addictive like pizza or fries just because it's there. It's why the packaged food companies are freaking out - all their work to engineer snacks where they can "bet you can't eat just one" is defeated by these, at least for now.
