‘Fibermaxxing’ Sweeps TikTok as Gen Z Fuels a High-Fiber Food Revolution

A new wellness trend called 'fibermaxxing' is taking off on TikTok, especially among Gen Z users. The movement focuses on boosting fiber intake for better stomach health. Now, major food brands and retailers are jumping on board with high fiber foods and marketing campaigns.

The trend follows earlier wellness crazes centered on hydration and protein. Medical experts recommend 25 grams of fiber daily for adult women and 35 grams for men. Many consumers see high fiber foods as healthier—42% believe the label signals better nutrition, while 52% want to try 'fibermaxxing' themselves.

Retailers are already seeing demand grow. Thrive Market reported a 30% rise in searches for high fiber snacks, bars, and supplements over the past year. Whole Foods predicts that by 2026, packaging will highlight fiber more prominently, with added fiber becoming a common feature in new products. Big food companies are rolling out high fiber options. PepsiCo is expanding its line-up with SunChips, Smartfood popcorn, and Propel hydration packets, building on the success of its gut-friendly soda. Even fast food could join in—McDonald’s CEO recently named high fiber as a major trend for 2026. Scientists note that high fiber helps regulate appetite by stimulating GLP-1, a hormone that reduces hunger. This benefit adds to its appeal for health-conscious shoppers.

The 'fibermaxxing' trend is pushing food brands to reformulate and market products with higher fiber content. With growing consumer interest and retailer support, high fiber is set to become a key focus in wellness products. Medical guidelines and appetite-regulating effects further strengthen its position in the health food sector.
