A “detox” (or “cleanse”) involving a special diet, supplements, or a specific regimen to rid the body of toxins in order to improve health or promote weight loss is not necessary.

Detox, short for detoxification, is often suggested as a way to remove toxins from the body, lose weight, or promote health.

In medical terms, detox refers to the treatment of people with drug or alcohol addictions or a treatment to rid the body of poison. This type of treatment is usually done in a clinic or hospital and may involve the use of medications and other therapies depending on the type and severity of the toxicity.

There is no reason a healthy person should need to “detox” because the body eliminates toxins on its own through the liver, kidneys, skin, lungs, and digestive system. There is no need for supplements or special diets to do this. If the body is unable to remove toxins, they could accumulate and a person would need medical treatment.

In popular culture, the term “detox” (or “cleanse”) often refers to following a special diet, use of supplements, or a specific regimen to rid the body of toxins. They often claim that the removal of toxins will improve health and may promote weight loss.

What Does Detox Do for Your Body?

There have been only a small number of studies on “detoxification” programs and a 2015 review of existing studies showed there was no compelling research to support the use of “detox” diets for weight management or eliminating toxins from the body. Another review in 2017 review said juicing and some “detox” diets may cause initial weight loss because of low caloric intake but weight gain will recur after a person resumes a normal diet.

That said, there are ways to stay healthy and to support the organs that detoxify the body naturally.
