Fibermaxxing Is a Diet Trend Even Nutritionists Can Love

For decades, nutrition experts have been urging Americans to eat more fiber. For decades, Americans have ignored them. But now it looks like they’re finally paying attention.

First came healthier sodas, boasting not just lower sugar than regular pop but added fiber too. In January 2025, the creator of the famously indulgent Jeni’s Splendid Ice Creams unveiled a fiber bar brand called Floura, which joined a growing list of new packaged-food products for the digestion-conscious consumer. Then we were deluged by TikTok “fibermaxxing” tutorials, with influencers talking up chia seeds, avocado and chickpeas. In restaurants, 45% of Americans are now actively seeking high-fiber options on menus, according to a recent survey from consultant firm Revenue Management Solutions, and even Chris Kempczinski, the chief executive officer of McDonald’s Corp., which has close to zero fiber on its menu, has predicted it will be a major food trend this year.
