Body cleansing and detoxification have been referred to as an elaborate hoax used by con artists to cure nonexistent illnesses. Most doctors contend that the 'toxins' in question do not even exist.[16][17] In response, alternative medicine proponents frequently cite heavy metals or pesticides as the source of toxification, however no evidence exists that detoxification approaches have a measurable effect on these or any other chemical levels. Medical experts state that body cleansing is unnecessary as the human body is naturally capable of maintaining itself, with several organs dedicated to cleansing the blood and gut.[18]
In the first decade of the 21st century, the conceptualization of health as an ability opened the door for self-assessments to become the main indicators to judge the performance of efforts aimed at improving human health.[11] It also created the opportunity for every person to feel healthy, even in the presence of multiple chronic diseases, or a terminal condition, and for the re-examination of determinants of health, away from the traditional approach that focuses on the reduction of the prevalence of diseases.[12]

You’ve probably come across all kinds of cleansing and detox programs online. There is a whole industry based around selling these plans and supplies to people trying to live healthier. Unfortunately, doctors largely agree that most of these plans have no real health benefits. They might even be harmful. It's best to skip them and follow a healthier lifestyle instead.
