Reply to comment by [deleted] in ELI5: What causes the stomach to make an audible grumble noise when it requires food? by bdcubedon12

But why does it seem to only happen when you're hungry, then?

I believe having contents in your stomach muffles it, and you produce more gases when food enters the bowels which takes a bit from the last time you ate. The time for food to pass through the stomach and small intestines is around 6-8 hrs, which is also somewhat close to the amount of time the average person takes between meals if they eat 3 meals a day.
