Signs You’re Eating Too Much Fiber and How to Fix It.
Wondering if it’s possible to get too much fiber? The recommended daily fiber intake is 25 grams for women and 38 grams for men, but around 95% of people don’t reach this amount. However, if you go overboard, you might experience bloating, stomach pain, gas, loose stools, constipation, temporary weight gain, reduced blood sugar (especially important for diabetics), or, in rare cases like Crohn’s disease, an intestinal blockage.
