So I heard a rumor a while back that bubblegum stays in your system for 7 years. I also heard that your stomach is about the size of both of your fists put together. It got me thinking. If you chew enough bubble gum the size of both of your fists combined and then swallow it instead of spitting it out then you'll be full for 7 years! Imagine all the diets that you could achieve just by staying full off one meal for 7 years!!!
