Health experts and dietitians are warning against the ‘fibermaxxing’ trend, where individuals rapidly increase dietary fiber intake to improve skin or reduce body fat. While fiber is essential for reducing risks of heart disease, diabetes, and colorectal cancer, experts note that sudden increases without adequate hydration can cause the body to ‘rebel.’

Reported symptoms of excessive or improper intake include bloating, diarrhea, constipation, and frequent bowel movements. Professionals recommend a gradual transition to higher fiber levels and suggest following anti-inflammatory patterns, such as the Mediterranean diet, which emphasizes vegetables, legumes, and whole grains while limiting ultra-processed foods and sugar.
