Constipation is a common concern for those starting a ketogenic diet. Low-carb diets are often low in fiber, which can slow digestion and make bowel movements irregular. But with the right high-fiber keto foods, you can maintain healthy digestion without compromising ketosis.
If you’re struggling with keto-related constipation, this guide will give you practical, problem-solving foods and tips to keep things moving naturally.
Why Constipation Happens on Keto
-
Lower fiber intake: Fewer fruits, whole grains, and starchy vegetables.
-
Dehydration: Low-carb diets often cause water loss.
-
Reduced gut motility: Fat-heavy meals can slow digestion in some people.
Getting enough fiber and hydration is essential to avoid discomfort, bloating, and irregularity.
