The Wellness Habit Some Experts Secretly Avoid Themselves

It gets rebranded with impressive regularity. Sometimes it is called a cleanse. Sometimes a reset. Sometimes a detox, a flush, or a gut protocol. Whatever the current name, the product is largely the same, and the market for it is enormous.

What is less often advertised is that the doctors and dietitians whose credentials appear in the promotional copy rarely do it themselves, because they know what the research actually says.

The Habit in Question

The juice cleanse and detox industry has operated for decades on a promise that the body accumulates toxins it cannot process on its own and needs external help to purge them. The appeal is obvious, the promise clean and simple, and the marketing around it expertly designed to feel medical without being medicine.

The problem, as a review of detox research put it plainly, is that no rigorous clinical investigations of detox diets have been conducted, and no evidence supports any of the health claims attached to them.

What the Body Is Already Doing

The liver, kidneys, gut, lymphatics, and skin are working continuously to remove waste and process what the body encounters every day. This is not a weekend project. It is a permanent biological function that does not require juice or supplements to operate.

A liver specialist quoted by Kaiser Permanente explained that the appeal of cleanses is mostly psychological, driven by the desire for a quick fix rather than genuine evidence of results. The feel-better effect people often report comes from cutting out the processed food, alcohol, and excess sugar that the cleanse temporarily replaces, not from any detoxifying ingredient in the drink itself.

The Risks Nobody Mentions in the Marketing

The industry’s preferred framing is that cleanses are at worst neutral and at best transformative. Physicians tell a different story. Juice cleanses can spike blood sugar, deplete electrolytes, and stress the gut lining, while liquid-only protocols remove almost all protein and fat from the diet, exactly the nutrients the body needs to function and repair.

There are documented cases of kidney damage linked to high-oxalate green smoothie cleanses, with the American Journal of Kidney Disease publishing a case report specifically on the phenomenon. That is not a footnote most cleanse companies include on the label.

What Experts Actually Do Instead

What registered dietitians recommend privately, and practice themselves, is considerably less photogenic. Eating a diet rich in fruits, vegetables, soluble fiber, beans, nuts, and whole grains while limiting alcohol gives the liver precisely what it needs to do its job well. Drinking water, sleeping enough, and avoiding highly processed food does the rest.

None of that sells very well in a bottle. But it is what the people who understand the research are actually doing at home, even while the cleanse market continues to grow around them.
