Overview

• The TikTok wellness community is split on fibermaxxing, with supporters praising energy and gut health gains and detractors warning of digestive distress.
• Fibermaxxing typically entails consuming 30 to 50 grams of dietary fiber per day, exceeding the USDA recommendation of 25 to 30 grams.
• Dietary fiber supports blood sugar control, cholesterol reduction, regular bowel movements, extended satiety and reduced chronic disease risk.
• Experts caution that sudden jumps in fiber intake can lead to gas, bloating, abdominal pain, diarrhea or constipation, especially if hydration is insufficient.
• Dietitians recommend a low-and-slow approach by adding fiber gradually to meals, drinking plenty of water and avoiding high-fiber diets during gastrointestinal surgery recovery or inflammatory bowel disease flare-ups.
