Detoxification, or detox, is the process of removing toxic substances from the body. Diets that claim to achieve a full detox in a matter of days have been around for decades, and several methods exist. While not scientifically proven to remove any toxins from the human body, many people claim feeling more focused and energetic during and after detox diets, most likely because of avoiding processed foods.

Note: This article does not contain information on how to detoxify someone undergoing treatment for alcoholism or substance abuse. Detoxing from alcohol or other hard substances, particularly benzodiazepines, should always be conducted under the supervision of a medical professional.

Do a fruit detox. Fruit detoxes are a great way to fast without starving yourself. Getting enough fruit can increase your energy levels, help manage your weight, and even reduce the likelihood of stroke.^{[1]

Research source} You can either detox by eating a variety of different fruits, or by only eating one kind of fruit. For best results, choose a fruit that you enjoy eating so that you don't feel like you're suffering. Do not exceed 7 days in a row of a fruit-only diet.
- Eat citrus fruits. Oranges, tangerines, grapefruit, lemons, and limes have the highest detoxifying effects.^{[3]

- Try a grape detox. Grapes contain resveratrol, which can protect against cancer and diabetes, and potentially prevent blood clots.^{[5]

Do a liquid fast. Consume nothing but liquids (water, tea, fruit juice, vegetable juice, and/or protein shakes) for 2-3 days.^{[6]

- Be sure to include fruit and/or vegetable juices in your liquid fast to ensure that your body is getting the proper nourishment.

Eat only fruits and vegetables for 7 days. Fruits and vegetables contain the vitamins, minerals, and other nutrients your body needs to stay healthy. Be sure to eat a diverse combination of produce to ensure that you are getting the proper nutrients. Use the following guide to determine what to eat during your fast:
- Get fiber from kidney beans, black beans, apples, soybeans, blueberries, and artichokes.
- Get potassium from carrots, bananas, lima beans, white potatoes, cooked greens, and sweet potatoes.
- Get vitamin C from kiwis, strawberries, kale, cauliflower, tomatoes, oranges, Brussels sprouts, mangoes, and bell peppers.
- Get folate from cooked spinach, melons, asparagus, oranges, and black-eyed peas.
- Get good fats from avocado, olives, and coconut.

Eat organically-grown produce and meat. Conventional produce is grown with chemical fertilizers and synthetic insecticides, while organic produce is grown with natural fertilizers and pesticides. Organic meats have far fewer harmful antibiotics, growth hormones, and medications that are fed to animals on conventional farms.
- Check labels to determine whether or not a food is organic. Organic foods should have a green USDA Certified Organic Seal.

Drink enough water.^{[9]

- Drink lemon water. Add lemon, orange, or lime juice to your water throughout the day. Plus, adding flavor to your water can make it a lot easier to get those 8 daily cups in! Brush your teeth in between meals to prevent acid erosion from the citrus.
Research has suggested that alcohol may be linked with the onset of certain types of cancer, including breast cancer in women. Though you don't have to cut it out entirely, stick to one glass of wine or beer a night, at most.
. Consuming excess sugar on a regular basis can cause your blood sugar levels to spike, putting you at greater risk for heart disease, diabetes, and certain cancers in the long run.Read all nutrition labels and beware of added sugars in bread, salad dressings, and sauces.^{[11]

Meditate. Many religions and philosophies advocate fasting as a way of refocusing the mind and developing a sense of peace. While you're detoxifying your body, try to rid yourself of grudges, anger, sadness, and other negative feelings. Use the time you would usually spend eating or preparing food to think about your goals and aspirations. Distill your thoughts in a journal.
Above all, find a balanced, achievable program that combines daily exercise and changes to a healthy diet, with regular, qualified supervision. Remember you are trying to set the stage for healthy habits - not further stress your body with rapid, extreme and unsustainable change. Try to avoid binging as you come off of detoxing.

Expert Answer

It depends. Once the detox starts, be prepared to nurse the person like you would if they have the cold or a flu. Depending on the substance, they may feel hot one moment and cold in another; they may want to eat a lot or not at all; or they may want to sleep for 3 days. Just support whatever their needs are during that time.

Something interesting about juices is that when you make them, you remove the fiber from the fruits and vegetables, and fiber is one of the main elements supporting our “natural detox system”. Some foods have components that support the normal detox system that our body has: broccoli, brussel sprouts, bok choy, and foods containing lean protein in the diet. I often recommend including juice ingredients in an amount that represents the fruit and vegetables that you would normally eat. For example, drink 1 small cup of juice made from 1 orange and 2 carrots, instead of 1 liter made out of 6 oranges and 20 carrots.

Unfortunately, most juice detoxes give a quick, unsustainable fix and cause more sugar and carb cravings once the juice cleanse is done.

Eat slowly. During a detox, you can stretch out your meals by chewing thoroughly and without hurry. Slow eating also aids digestion.

Try to find time for light exercise. Yoga, Pilates, swimming or brisk walking is ideal. Don't attempt strenuous activities such as running or weight training while fasting.

Even if you feel great on your fast, don't continue detoxing for more than 10 to 14 days at most. Long-term fasting or starvation can do irreversible damage to your metabolism.

Don't fast to the point of passing out. If you faint or feel strongly that you will, your diet has gone too far. Immediately eat a piece of bread or a biscuit to improve your blood sugar, and try to consume an electrolyte-rich sports drink. Lie or sit down, and put your head between your knees if possible. Do not resume the diet.

Don't just follow any detox diet you find online. Many of these are unsafe under any circumstances. Always run your plan past your general practitioner or a licensed nutritionist.
