The claim “Clean 15 kilograms of waste from your colon in one night” is not supported by medical evidence.
Here’s why:
- A healthy colon does not normally contain 15 kg (about 33 lb) of “waste.” Stool is passed regularly through normal bowel movements.
- The body does not accumulate large amounts of toxins in the colon that need to be “flushed out.” The intestines, liver, and kidneys continuously process and eliminate waste.
- Products or recipes advertised as “colon cleanses” or “detoxes” may cause diarrhea, which leads to temporary water loss—not removal of years’ worth of waste or fat.
- Frequent use of laxatives or colon-cleansing products can cause dehydration, electrolyte imbalances, and, in some cases, damage to the intestines.
If your goal is better digestive health
The following habits are supported by evidence:
- Eat plenty of fiber from fruits, vegetables, whole grains, beans, and lentils.
- Drink enough water.
- Exercise regularly.
- Include fermented foods (such as yogurt with live cultures or kefir) if they agree with you.
- Avoid smoking and limit highly processed foods.
If you’re constipated
If you’ve gone several days without a bowel movement or have hard stools, increasing fluids and fiber may help. Some people benefit from an over-the-counter laxative, but it’s best to use these according to the instructions or after consulting a healthcare professional, especially if constipation is persistent.
When to seek medical care
See a healthcare provider promptly if you have:
- Blood in your stool
- Severe or worsening abdominal pain
- Persistent vomiting
- Unexplained weight loss
- Constipation lasting several weeks despite self-care
- A swollen abdomen with inability to pass stool or gas
