For most of this year, health-conscious folks have been pretty obsessed with how much protein they’re eating every day — and sharing it all on social media. But recently, a different essential nutrient has come into focus: Fiber.

These days on TikTok, users are #Fibermaxxing, or increasing their fiber intake to get, or exceed, the recommended daily amount, and encouraging others to do the same.

The U.S. Department of Agriculture’s Dietary Guidelines for Americans encourages getting 25 to 28 grams of fiber a day for women younger than 50, and 31 to 34 grams daily for men under 50.

On social media, users are loading bowls up with chia seeds and fresh fruits and mixing together salads with vegetables and nuts to get as much fiber as possible, touting benefits like decreased bloating.

“People are doing that because it probably helps with digestion, weight management, weight loss [and] gut health,” says Mia Syn, registered dietitian and author of the cookbook, “Mostly Plant-Based.”
