What is Fibermaxxing?
Fibermaxxing (also spelled fibremaxxing) is a wellness trend that took TikTok by storm in 2025, where people intentionally maximize their daily fiber intake. The trend was popularized by wellness creators like Pamela Corral, whose TikToks about chia seed puddings and high-fiber meals have received millions of views.
Unlike many viral diet trends, fibermaxxing has earned rare approval from nutritionists and dietitians. The New York Times, The Guardian, and CNBC have all covered the trend positively, noting that most Americans genuinely need more fiber — the average intake is only 15g per day, roughly half the recommended amount.
Is Fibermaxxing Safe?
Yes, with caveats. Increasing fiber intake is one of the best things most people can do for their health. However, the "maxxing" part requires some caution:
✅ Do
- • Increase fiber gradually (3-5g/week)
- • Drink plenty of water
- • Eat a variety of fiber sources
- • Aim for 25-38g per day
- • Include both soluble and insoluble fiber
❌ Don't
- • Jump from 10g to 50g overnight
- • Exceed 70g/day (can block mineral absorption)
- • Rely only on fiber supplements
- • Ignore digestive distress signals
- • Skip water (fiber needs it to work)
