Summary

The average person eats 10-15 grams of fiber per day, according to the USDA. The problem? That’s WAY under the recommended daily amount.

Fiber – a type of carb that our bodies are unable to digest – is prevalent in foods like fruits, veggies, whole grains, and beans. And it’s key for everything from feelings of fullness, to gut health, to good poop. That’s why a lot of people online are “fibermaxxing”: trying to meet or exceed the daily recommendation of fiber, in hopes it’ll improve their health.

But how should YOU add fiber to your diet… and are the fibermaxxers overdoing it? Gastroenterologist Berkeley Limketkai is here to help parse the science on how little fiber is too little, how much fiber is too much – and, like Goldilocks, how we can figure out the amount that’s just right.
