The claim “Clean 15 kilograms (33 pounds) of waste from your colon in one night” is not supported by scientific evidence.
Here’s why:
- Your colon is not designed to store 15 kg of old waste. In healthy people, it continuously moves stool out of the body.
- Even if you take a strong laxative or undergo bowel preparation before a colonoscopy, the weight lost is mostly stool, water, and intestinal contents—not years of accumulated “toxins.”
- There is no evidence that the average person has large amounts of hardened waste coating the colon that need to be “detoxed.”
What actually promotes a healthy colon?
- Eat plenty of fiber from fruits, vegetables, whole grains, beans, and legumes.
- Drink enough water.
- Get regular physical activity.
- Don’t ignore the urge to have a bowel movement.
If you’re constipated
Safe, evidence-based options include:
- Gradually increasing fiber intake.
- Drinking more fluids (unless your doctor has advised otherwise).
- Prunes or kiwi, which can help some people.
- If needed, over-the-counter laxatives used according to the directions or a healthcare professional’s advice.
Be cautious of “colon cleanse” products
Products marketed as colon cleanses or detoxes may cause:
- Diarrhea
- Dehydration
- Electrolyte imbalances
- Abdominal cramps
