Fiber Training Gains Traction With 5 Tips for Raising Gut-Health Intake

1 articles · Updated · VICE · May 15

Five practical tips anchor the latest “fiber training” trend, which centers on gradually increasing fiber rather than making abrupt diet changes that can trigger digestive discomfort.
Avery Zenker, a registered dietitian at MyCrohnsandColitisTeam, said the approach helps the gut microbiome adapt because people who usually eat little fiber may need time to tolerate more.
Zenker’s advice starts with a “fiber five” of vegetables, fruits, legumes, whole grains, and nuts or seeds, plus a 5,4,3,2,1 daily target for variety across those groups.
The plan also emphasizes easy execution—mixing lentils or beans into familiar meals, swapping in higher-fiber staples, and using snacks like popcorn, hummus, roasted chickpeas, or granola to close the gap.
The broader message is personalization: fiber training should vary by fiber type, quantity, timing, water intake, and individual health needs rather than follow a one-size-fits-all social media formula.

With the 'fibermaxxing' trend on the rise, what are the hidden health risks of overdoing it?
