Detox diets are often touted as a way to cleanse the body after the excess food and drinks that come with the holidays. These diets promise quick results and can particularly entice people around the new year, when there tends to be a renewed focus on health and lifestyle habits.
There are a few different types of detox diets: fasting, juice cleanses, eating only certain foods, using dietary commercial detox supplements or “cleansing” the colon with enemas or laxatives.
Most of these diets have a few things in common: They are short-term and aim to eliminate allegedly toxic substances from the body. Typically, these diets include a period of fasting followed by an extremely restrictive diet for a number of days.
As a registered dietitian, I have seen clients attempt detox diets and experience a slew of negative side effects, including developing a negative relationship with food.
Research shows that there is little evidence to support the use of detox diets and that they are not needed anyway. The body is well-equipped to eliminate unwanted substances on its own, without expensive and potentially harmful supplements sold by the nutrition and wellness industry.
About toxins
What are toxins – and how do they get into the body in the first place?
Internal toxins include natural byproducts created by the body during metabolism, such as lactic acid, urea and waste from the gut microbes.
External toxic exposures enter the body through eating, drinking, breathing or penetration of the skin. These can come in the form of air pollutants, food or water contaminated with chemicals or heavy metals, household products such as laundry detergent and even beauty products like facial cleansers, body wash and makeup.
The body’s built-in detoxification system includes the liver and kidneys, with assistance from the lungs, lymphatic system, digestive tract and skin. Briefly, the liver breaks down harmful substances, which are then filtered out through the kidneys. The digestive tract also expels them through bowel movements.
But our bodies aren’t always functioning optimally. That’s why a proper diet and improved lifestyle behaviors, such as increased exercise and sleep, may have a significant – and positive – impact on the body’s detoxification system.
Having a diverse microbiome and an abundance of healthy gut bacteria also helps to rid the body of harmful substances. Fermented foods such as kefir, sauerkraut and cultured dairy products can benefit gut health. These foods contain probiotics, which are the beneficial bacteria that live in your gut.
Another category, called prebiotic foods, are also beneficial for gut health. They provide nutrition and energy for the healthy probiotics in the gut and are high in fiber. Examples of prebiotic foods are whole grains and fruits and vegetables, particularly bananas, greens, onions and garlic.
Although proponents claim that detox diets and juice cleanses lead to weight loss, improved liver function and overall better health, research shows they have little to no effect. What’s more, they can lead to side effects, including headaches, fatigue, weakness, fainting and irritability. However, studies show there is some evidence that certain foods and spices, such as coriander, may enhance the body’s natural detoxification pathways.
According to the Academy of Nutrition and Dietetics, other foods that may give the body’s own detox system a boost include cruciferous vegetables like broccoli and Brussels sprouts, berries, artichokes, garlic, onions, leeks and green tea. Eating adequate amounts of lean protein may also benefit the body’s natural system by maintaining adequate levels of glutathione, the body’s master detoxification enzyme, or catalyst. Glutathione is an enzyme produced by the liver that is involved in numerous processes within the body including building and repairing tissues, assisting in the natural detoxification process and improving immune system function.
Some detox diets and programs can have serious side effects, particularly those including laxatives or enemas, or those that restrict intake of solid foods. These approaches can lead to dehydration, nutrient deficiencies and electrolyte imbalances.
Instead, these types of diets often put the body into “starvation mode.” That means that rather than burning calories, your body holds on to them to use as energy.
Doing that repeatedly over a long period can lead to a chronic decrease in metabolism, which means that the number of calories you burn at rest may slowly decrease over time. This can make it more difficult to lose weight and balance blood sugar. It can also leave people more susceptible to chronic metabolic conditions such as cardiovascular disease and diabetes.
A healthy lifestyle, without the detox diet
Focusing on sustainable lifestyle shifts can make a huge difference – and unlike a detox diet, actually work.
Number one, eat a balanced diet. Aim to eat mostly whole grains, lean protein choices, fruits and vegetables of many colors, low-fat dairy, nuts and seeds. This way, you’re getting a variety of nutrients, antioxidants and a good amount of fiber.
Number two, hydrate. For women, the recommended daily water intake by the Academy of Nutrition and Dietetics is 11½ cups; for males, it’s 15½ cups. However, you get about 20% of that total from food, which leaves nine cups for women and 13 cups for men as the daily recommended water intake. This is comparable to 4½ 16-ounce water bottles for women and 6½ 16-ounce water bottles for men.
Lastly, move your body in a way that you enjoy. The more you enjoy being active, the more likely it will become a routine. Aim for at least 150 minutes, or 2½ hours of moderate-intensity physical activity every week.
Focusing on these types of long-term, sustainable healthy habits is the key to weight loss and overall health and wellness.

"If you're reading this article, kudos to you for thinking about reevaluating social media," Agarwal said Trying to meet your goals is all about celebrating the small wins.
At the least, set small benchmarks for yourself like spending 10 minutes less on social media than the day before. The right amount of social media time is different for everyone since some people actually use these apps to brand and help market themselves. Find your own social media sweet spot, and remember, even if you scroll too much on social media one day, you can try and meet your goal tomorrow.
Another way to keep you on track is to share your goal with someone you trust. A friend or loved one who can kindly nudge you when they notice you've been on social media for awhile.

Scrolling through social media while hanging out with friends isn't uncommon nowadays, but when you think about how unengaged you are in those moments, it can put social media use into perspective.
Agarwal suggests the next time you're in a room with others at a family or friends gathering and you see yourself scrolling through social media instead of engaging with others, take a minute to physically remove yourself from the room and isolate in another room. Listen and feel how much you may be missing out on.
"What that does is it gives your brain a signal. If you force yourself to leave the room, you realize how much you're using that app and missing out on other people," Agarwal said. "It's a good physical reminder of being present in the moment and not on your on your phone and scrolling through social media."

Most smart phones nowadays track your screen-time and usage already. It's a good idea to figure out your average screen time per day so you have a benchmark that you can work on.
On iPhone, you can go into your "Screen Time" settings, which displays the amount of time you spend on each app and allows you to put timers on specific apps to limit how long you're on them. Android phones have similar features in the "Digital Wellbeing" settings. Additionally, Facebook, Instagram and TikTok offer the same features within the app settings themselves.

When you're at home and have free time, put your phone in a drawer or somewhere you can't see it. Oftentimes limiting the ability to quickly and easily pick up your phone is enough to keep you off of social media, said Agarwal. If your phone is what keeps your hands from fidgeting, try to have some objects around the house that relieve stress, like a stress ball, fidget toy or yarn and crochet hooks.
Hide your social media apps on your phone by placing the app on the second or third page of your home screen or bury the app inside an "app folder" with a bunch of others. When you're waiting in line or have a free five minutes, instead of grabbing your phone — take in the view, practice some breathing exercises or read a book.

Ever hear of "text neck?" It's the result of looking down at our phones when scrolling or texting, straining the neck muscles over a long period of time. Taking a break from social media helps relieve neck pain and gives your eyes a break from bright screens.
People may also be more connected than ever through social media, but a 2018 University of Pennsylvania study found that people who limit their time on social media experience less depression and feelings of loneliness.
Taking a break from social media will give you better sleep, too. Research suggests that nighttime use of social media is driven by FOMO (fear of missing out), and keeps people scrolling longer at night instead of going to sleep.

What is the reason that brought you onto social media? This is the question Agarwal said to ask yourself when trying to figure out if it's time to take a social media break. If you're not getting the same satisfaction from the reason you use social media, it may be time to look for alternatives.
If you joined social media to...
1. Find community: Look for clubs and groups in your neighborhood where you can meet and interact with others IRL (in real life).
2. Be inspired: Consume other forms of media like magazines, books, podcasts, movies or live events.
3. Buy and sell things: Try using other apps, like OfferUp or NextDoor, or visiting local events and marketplaces in person.

Two and a half hours — that's the average amount of time people spend on social media each day.
It may not sound like a lot, but that time can really add up — and at what cost? Social media has proven negative effects on mental health (especially for teens), self-image and for some is a huge time-waster.
University of Penn's Anish Agarwal, an emergency physician, researcher, and deputy director for the Center for Digital Health, said it's important to constantly be reevaluating the role social media plays in daily life.
The bottom line: taking a break from social media is healthy for you. Read on for guidance and tools to help you limit screen time on these apps.
