If you’ve ever dipped your toe into the seemingly infinite world of wellness trends, chances are you have come across the ‘detox’ fad.
Walk into any health food store and you’ll find them: green juices in Instagram-worthy bottles, capsules filled with mysterious powders, sticky foot pads and expensive ‘cleanse kits’ all promising to rid your body of ‘toxins’, some specified and some not.
The wellness industry has sold a simple, seductive story – that you need to pay a hefty price to purify your body.
But the truth is that your body already comes with a built-in detox system that works 24/7 – for free.
Your liver, kidneys, lungs and skin are constantly filtering waste, breaking down chemicals and eliminating what you don’t need. The real question isn’t which juice or supplement to buy; it’s what you can do to help your body’s natural detoxifiers work at their best.
Andrea Holwegner, a registered dietitian, told the Daily Mail: ‘The human body is already designed to detox itself. What most people actually need is not a harsh cleanse, but a return to consistent, nourishing habits they can sustain for life.’
Detoxing doesn’t involve fasting for days or drinking cayenne-pepper lemonade. Instead, it comes down to a handful of evidence-backed habits that help your organs do what they already do best.
Experts have shared with the Daily Mail tips on how to support your body’s natural detoxification process without falling for expensive – and potentially dangerous – gimmicks.

When you feel sluggish, bloated or foggy, more often than not, the real culprits are sleep disruption, too much alcohol, a diet heavy in ultra-processed foods, chronic stress and dehydration.
The fix isn’t a cleanse but rather getting back to basics.
Juice cleanse programs typically involve drinking anywhere from four to six juices per day for three, five or even seven days, and eating little to no solid food.
The promises are bold, including to flush out toxins, boost your energy, clear your skin, lose weight fast and give your digestive system a break.
Some claim to ‘reboot’ your liver or ‘alkalize’ your blood, though none of that is backed by science.
A three-day juice cleanse can cost $150 to $300 or more – coming to about $50 to $100 per day for what is essentially fancy, cold-pressed, fiber-free sugar water with some vegetable juice mixed in.
Johannah Katz, a registered dietitian, told the Daily Mail: ‘Juice cleanses may temporarily increase micronutrient intake but are typically low in protein, fiber and total energy, which can impair satiety, blood sugar regulation and lean mass maintenance.
‘There is no clinical evidence that juice cleanses remove toxins or improve endogenous detoxification capacity beyond a balanced diet.’
Supplements often promise to ‘flush toxins’ or ‘cleanse your gut,’ but these claims are rarely backed by science and usually rely on fear-based marketing rather than evidence (stock)
Holwegner added: ‘In my professional opinion, juice cleanses are mostly an expensive distraction. Some people feel temporarily better on them, but that is often because they are cutting back on ultra-processed foods, drinking more fluids and paying more attention to what they consume overall.
‘That does not mean the juice itself is “flushing toxins” from the body. In fact, replacing meals entirely with juice can leave people under-fueled, low in protein, low in fiber and more likely to experience fatigue, dizziness and rebound overeating later.’
Experts warn against any detox product that promises toxin removal without naming the toxins or explaining how, rapid fat loss without behavior change, reliance on laxatives or diuretics, extreme calorie cutting without enough protein or fear-mongering about parasites and hidden poisons.
Holwegner said: ‘I would also be cautious of anything that cannot realistically be followed long term. If it is extreme, expensive, or rooted in shame and restriction, it is unlikely to support lasting health.’
Activated charcoal is another popular yet dubious detox ingredient. It has one legitimate use: treating certain poisons in an emergency room.
Outside that setting, however, it’s risky. It binds to medications, supplements and fat-soluble vitamins, stopping the body from absorbing them.
That means a person could accidentally undo the benefits of a vital blood pressure pill or daily multivitamin.
For a healthy person, routine charcoal use offers no proven benefit, only potential harm.
A major marketing red flag, Katz said, is the use of charcoal as a cleansing agent.
Another, potentially dangerous gimmick is the parasite cleanse. Most of these cleanses are built on inducing consumer paranoia, not science.
Katz said: ‘Most commercial “parasite cleanse” protocols are not supported by clinical evidence in individuals without a confirmed parasitic infection.
‘In many cases, these products may reflect fear-based marketing rather than evidence-based medicine and can sometimes lead to unnecessary dietary restriction or GI disruption.’
Most people just need consistent, nourishing habits they can live with, not fasting or cayenne-pepper drinks. A few simple, science-backed practices are all it takes to support your liver and kidneys (stock)
For people looking to detox, they can do a simple, science-backed reset in as little as a weekend, Holwegner said.
‘Over a weekend, [people] might reduce alcohol, cook a few nourishing meals, step away from social media for a stretch and catch up on rest,’ she said.
Or, they can dedicate more time to solidifying healthy habits.
‘Over a week, the most powerful reset is re-establishing structure: consistent eating times, better hydration, more fiber-rich foods, enough sleep, and less “all-or-nothing” thinking around food.
‘Those changes are sustainable and far more evidence-based than a cleanse,’ Holwegner added.
She recommends making small changes at first.
That means increasing fiber and cruciferous vegetables to support gut health and natural waste elimination, ensuring adequate protein to fuel your liver’s detox enzymes, prioritizing sleep consistency so your body can do its nightly restoration and removing or reducing alcohol to decrease the burden on your liver.
Andrea Holwegner, a registered dietitian, explained to the Daily Mail that the human body doesn’t need outside help to detox. What it needs, she said, is a return to balanced, consistent habits that are sustainable over time
Fiber-rich foods such as oats, beans, lentils, apples, berries and whole grains bind to toxins and waste products in bile and sweep them out through the stool before they can be reabsorbed in the digestive tract.
They contain a compound called sulforaphane, which sends a chemical signal to your liver to ramp up production of its detox enzymes.
Together, fiber and sulforaphane don’t ‘cleanse’ your body in the gimmicky sense; they simply help the liver and gut do what they already do best, more efficiently.
The liver needs protein; specifically, the amino acids found in eggs, chicken, fish, tofu, beans and Greek yogurt, to produce its detox enzymes, which break down toxins and tag them for removal.
Protein-rich eggs, poultry and fish provide critical amino acids for glutathione, the body’s master antioxidant, while plant options add fiber to help carry toxins out through the stool.
Aim for a palm-sized portion of protein, about three to four ounces, at each meal.
Because the liver can’t store amino acids – it needs a steady, consistent supply throughout the day to keep its detox system running smoothly – more is not better, so stick to that palm-sized rule, nutritionists said.
Adults need seven to nine hours per night – and consistency matters. Going to bed and waking at the same time helps the body clear waste more efficiently.
Roughly eight cups of water daily helps kidneys flush out waste.
These habits aren’t glamorous and will require a trip to the grocery store. But they don’t require expensive pills, pads or potions.
