The ‘Fibermaxxing’ TikTok Trend: Here’s What’s Fact Versus Fiction

TikTok’s #fibermaxxing trend is pushing people to eat more fiber, with celebrities like Danielle Fishel and Lance Bass helping popularize it.

Nutrition experts say fiber can support digestion, cholesterol, blood sugar, and overall gut health, and the trend broadly matches established guidance.

Despite the hype, many Americans still fall short of recommended fiber intake, so the real challenge is increasing it safely and realistically.

Experts caution that fiber should be added gradually and with enough fluids to avoid discomfort or constipation.
