You know what else can tell you to eat more fiber?

Paying attention to your shit.

Is it coming out like curry sauce being shot through a hose? Time to eat more fiber!

Is it coming out like a large sausage? You get enough fiber.

There's possibly medical usage for this, by doctors, in certain scenarios, but there's no reason for the general consumer to require this beyond capitalism and consumerism.
