As a wellness editor, I’m curious to try all the things—I throw a little colostrum and collagen protein powder in my smoothies, for example. Come to find out, according to the latest TikTok craze, I’ve been neglecting a basic food category that’s kept me from feeling (and er, pooping) my best. The craze is known as fibermaxxing, the practice of consuming a large amount of dietary fiber every day. It’s supposed to not only optimize your energy but also forestall all sorts of diseases. However, I’m a skeptic at heart, so I checked with a nutritionist about how many leafy green vegetables I need to eat in an hour. Or something.
