A variety of “detoxification” (“detox”) diets and regimens—also called “cleanses” or “flushes”—have been suggested as a way to remove toxins from your body or lose weight. They may involve a variety of approaches, including fasting, consuming only juices or other liquids for several days, and cleansing the colon (lower intestinal tract) with enemas, laxatives, or colon hydrotherapy (also called “colonic irrigation” or “colonics”).
Be aware that there isn’t any convincing evidence that detox/cleansing programs actually remove toxins from your body or improve your health. Weight loss on a detox diet may occur simply because these diets are often very low in calories.
Even more important, some detox products or procedures may be harmful to your health. The side effects of some procedures, such as colon cleansing, can be serious. And diets that severely restrict calories or food choices usually don’t lead to lasting weight loss and may not provide all the nutrients you need.
