Juice Cleansing Explained

I'm often asked to name one thing that can be done right away to get healthier. With respect to food choices, the best suggestion I have is to begin drinking freshly pressed vegetable juices. Drinking just one freshly pressed juice each day is a reliable way of infusing your body with a wide variety of vitamins, minerals, and phytonutrients that can protect your cells against premature aging and disease.

Making time to drink vegetable juices isn’t a problem for most people. It’s the time that's needed to wash fresh vegetables, feed them through a good juicer, and clean the juicer afterward that prevents most people from making fresh juices a regular part of their lives.

But if you understand how beneficial freshly pressed juices are to your health, it becomes easier to make the time to juice several times a week.

The Right Ingredients

The key to creating healthy vegetable juices is to make green vegetables the bulk of every batch. Green vegetables won’t spike your blood sugar and insulin like fruits and sweet vegetables like carrots and red beets will.

This isn't to say that you can’t juice fruits, carrots, and red beets. Fruits and sweet root vegetables can be healthy additions to your drinks, and they'll definitely add sweetness and flavour. You just want to make sure that they never make up more than one-third of each glass that you drink.

And if your blood sugar level tends to be high, you’ll want to use a blood sugar monitor to determine how much is acceptable for you. I’ve worked with many diabetics over the years who haven’t been able to handle even an ounce of fruit, carrot, or red beet juice in their drinks without negative health consequences, so please consider this point before you select your ingredients for juicing.

Romaine lettuce is one of the best green vegetables that you can juice. You can also juice other types of leafy lettuce like red or green leaf lettuce.

For variety, try adding large handfuls of kale, Swiss chard, collard greens, Bok Choy, and other dark green vegetables that you might steam before eating.

For another layer of flavour, you can add a tiny slice of lemon (including the rind for its flavonoids) to your vegetable juices.

Some people enjoy adding a clove of raw garlic for even more bite.

Be creative and add any vegetables you crave. You really can’t go wrong as long as you make sure not to use too many carrots, red beets, or fruits.

Clearly, organic vegetables are better than non-organic vegetables. But my experiences have led me to believe that the health benefits of drinking juices made with well washed, non-organic vegetables far outweigh not juicing at all. If you're only able to juice non-organic vegetables due to financial or other life circumstances, it’s still well worth doing.

Preparing to Juice

We like to fill up the kitchen sink with cold water and dunk all of our vegetables for a good five minutes. Before we pull all the vegetables out to sit in a colander to dry off a bit, we shake them around in the cold water to make sure that we’ve removed any dirt or even bugs that may be hiding in the vegetables, particularly in heads of celery and lettuce.



If we know that we need to make a few gallons of vegetable juice over several days, we store washed carrots and ribs of celery in containers full of water in the refrigerator.

We store leaves of lettuce spread out and stacked vertically in a container with layers of paper towel in between each layer of lettuce to help absorb excess moisture. Fresh lettuce can last a whole week or more when stored in this fashion.

If you’re really pressed for time and want to make enough juice to last three to four days, you can make a big batch and store it in an air-tight container in the refrigerator - not as good as drinking right after pressing, but still likely better than drinking store-bought fruit juices or even vegetable cocktails like V8.

The Art of Juicing

Juicing is, for the most part, quite easy to do. You make sure that your vegetables are small or crunch-able enough to fit through the feeding mechanism of your juicer, and you push them in one at a time.

It's best to juice soft vegetables like leafy greens first, as they're a bit harder to push through the extraction mechanism than firmer vegetables like carrots and celery. Firmer vegetables like carrots and celery can actually help push through any bits of softer vegetables that are deep within the feeding tube of your juicer but not yet
completely through the extraction mechanism.

With leafy greens, we like to roll them up into small balls before feeding them through the juicer. This helps prevent a single leaf from getting stuck between the feeding tube of the juicer and the plunger that you use to push the vegetables down.

Fruits, like firmer vegetables, can be added near the end, as you're unlikely to have a problem pushing them down and through the extraction mechanism with the plunger.

How To Experience An Effective Juice Fast

Now that we've reviewed the fundamentals of how to make healthy vegetable-based juices, let’s take a look at how to carry out an effective juice fast.

Some people call juice fasting juice dieting, preferring to reserve the word "fasting" for water-only fasting. Juice fasting and juice dieting are the same thing.

Why consider doing a juice fast?

Drinking only freshly pressed vegetable-based juices for a day or two or even a week at a time can give your body much needed rest and time to heal itself of chronic health problems.

Because vegetable juices are extremely easy to digest, your body can spend much of its resources on healing damaged or exhausted tissues instead of spending its energy on digesting heavy meals.

You should only do a juice fast after consulting with your health care provider and confirming that your current health status should allow for a safe and effective juice fast.

A properly conducted juice fast may help you experience:

  • More energy

  • Healthier skin

  • Better quality sleep

  • Improved cardiovascular health

  • Reduction or elimination of aches and pains in muscles and joints

  • Decrease or elimination of headaches

  • Stabilization of blood pressure

  • More efficient digestion

  • Stabilization of bowel movements

  • Loss of excess weight

  • Elimination of stored toxins

  • Improvement with a wide variety of chronic degenerative health
    conditions, including autoimmune disorders

What’s the difference between a juice fast and a water fast?

People detoxify and heal more quickly with a water fast than with a juice fast. This is because with a water fast, your digestive passageway and organs are able to rest completely, which allows almost all of your energy to be used for cleansing and repair of damaged tissues.

With a juice fast or a cleansing diet of fruits and vegetables, your body must use energy (a minimal amount compared to when you are eating heavier meals) to digest nutrients, leaving less available energy for detoxification and healing.

Another significant difference is that more fat tissue is burned during a water fast, as your body must rely exclusively on fat reserves to supply its energy needs after the first one to three days of water fasting. Your body stores the bulk of incoming toxins in your fat reserves. As these reserves are burned for energy during a fast, any stored toxins will be released into your circulation, to be eliminated from your body through channels like your urine and respiratory tract. This mechanism of detoxification also occurs with juice fasting, but at a slower pace.

All of this considered, both types of fasting can be helpful to your health. The choice you make should take into consideration your circumstances and goals.

Generally, juice fasting allows for more gentle detoxification than water fasting. Juice fasting also allows you to have enough energy to keep up with most of your activities of daily living while you detoxify your tissues, whereas an effective water fast requires almost complete physical rest.

Another significant difference is that juice fasting is much easier for most people to stick with. Water fasting is best carried out in a supervised setting while juice fasting is relatively easy to do from your own home.

How long should you juice fast for?

It really depends on your health status and goals. If you’re looking to give your body a short but beneficial break, it can be helpful to do a juice fast for 48-72 hours over a weekend.

If you’re looking to experience significant detoxification and improvement in your overall health, you might consider doing a longer juice fast, somewhere in the ball park of one to two weeks.

Although it’s optimal to prepare for a juice fast by eating raw fruits and vegetables for 24 hours prior to beginning with juices only, most people do just fine in starting with juices without a pre-fasting routine.

You can drink however many juices your appetite calls for throughout the day. I have found that most people do well with an average of five freshly pressed juices per day.

You can use any of the juice recipes that are listed above, or any similar recipes that you create following your tastes.

While I generally recommend that people use fruit-based juices early on in the day and turn to vegetable-based juices as the day goes on, there’s really no requirement to stick to a specific order of juices.

A typical day of juice fasting might look like this:

Honeydew (cut into strips)
Lemon wedge

2 carrots
2 ribs of celery
8 leaves of romaine lettuce

3 ribs of celery
2 apples
Small handful of strawberries

2 tomatoes
3 ribs of celery
1 carrot
Lemon wedge

Large bunch of kale
2 carrots
2 ribs of celery

If necessary, it’s fine to make all of your juices for the day in the morning and to carry a few with you to work in air-tight bottles.

If you take a green food supplement, it would be an added bonus to include a tablespoon of such a product to one of your vegetable-based juices. The only caveat is that your green food product should not contain any fillers like lecithin, apple pectin, whole grains, or ground flax seeds. Any green food powder that is used during a juice fast should be composed of 100 percent green vegetables if you are looking for optimal results.

I have found that it's best not to take supplements that provide concentrated amounts of high quality fat during a juice fast, such as fish oil, cod liver oil, or flax seed oil.

The key guiding principle with juice fasting is to follow your instincts. Your body will tell you how many drinks you need per day and what types of vegetables and fruits you need to incorporate into your juices.

Ending Your Juice Fast

You should end your juice fast by eating whole fruits and vegetables. Good examples include:

  • Small bowl of watermelon

  • Small bowl of honeydew

  • 1 apple

  • 1 pear

  • Handful of grapes

  • Cucumber

  • Tomato

  • Celery sticks

Be sure to chew your food until liquid. This is critical to maintaining the positive changes that you will have created in your GI tract with your juice fast.

You can have another similar meal about two hours after the first one, and continue to eat small portions of fruits or vegetables for the rest of the day.

The second day of eating whole foods can include some steamed vegetables along with raw fruits and vegetables.

On the third day, you can add a cooked starch, such as a steamed potato or sweet potato. You can also add a grain dish if your appetite calls for it.

Beginning on the fourth day of re-feeding, you can add legumes, such as chickpeas or black beans.

Beginning on day five, you can add small portions of clean animal foods, such as organic eggs or wild salmon.

Beginning on day six, you can return to eating a well balanced diet that includes any healthy plant and animal foods that your body craves.

Over the long term, I've found that it is best for most people to follow a diet that consists of approximately 80 percent plant-based foods and 20 percent animal-based foods. But again, I always recommend listening to your own instincts and cravings.

Please keep in mind that this re-feeding schedule should take into account the length of your juice fast.

If you do a three-day juice fast, you probably won’t have any problems following this re-feeding schedule.

If you fast for more than a week, you may find that you won’t want to add cooked foods or animal foods back to your regimen until after you spend a few weeks eating raw fruits and vegetables.

One last time, the guiding principle is to follow your instincts.

If you don’t do a juice fast, you can still experience significant health benefits by including vegetables juices in your daily routine on top of your regular food choices.

If you don't have a juicer, two that I can recommend are:

The Champion Juicer

The L'Equip Pulp Ejector Juicer

If you prefer stainless steel appliances, here's an excellent choice at Amazon:

Breville 800JEXL Juice Fountain Elite 1000-Watt Juice Extractor

To close, here are a few photos that I took the other day as I juiced up a favorite blend of lettuce, celery, peppers, red beet, and lemon:






When you're finished juicing, you'll find a layer of bubbles at the top of your bowl - you can drink these right up with your juice, or if you prefer, you can skim them away with a spoon.



This is some serious, life-sustaining stuff, so drink with gratitude and enjoy knowing that you're taking great care of yourself.

In addition to the garlic or lemon to vary and enhance flavors, some veggies are complemented by the burst of flavor from a knob of raw ginger.

Sunchokes are noted for their prebiotic nutrients, and I wonder if, in moderation, they might be a useful ingredient in a juice regimen ...

When I don't feel like pulling out my juicer as I don't have space on my counter to leave it, I pull out my Vitamix and "juice" in it. I add enough water so I have a full Vitamix full and drink that through the day. I always put greens in with my fruits, though don't use sweet fruits like banana's or dates but stick to apples, pears, grapefruit, cranberries, blueberries, etc.

I am Emmanuel from Uganda.we have lots of fruits in this topical country.I have been an ardent reader of your blog but i must say i live a better healthy life because of your health professional advise .Am going to make it a point and make juices from your juice recipes.

Thanks so much Mr Kim.


It's always a bliss to be in a tropical country; you won't have any problem finding the freshest organic fruits and vegetables.

I'm a believer of juicing but too few people embrace this lifestyle in my part of the world; people here still enjoy the American / Western diet, burgers, fastfood, etc. too few understand that they can get healthy by eating healthy; it's no brainer but the majority just don't get it or maybe preparation is just too much of a hassle.

...Or maybe the high price on produce at the supermarket forbid people to eat healthy :(

David- If you are buying only organic produce, maybe you're right, but in many cases, pound-for pound, whole foods are cheaper than processed foods. Except for items on Environmental Working Group's Dirty Dozen list (incl apples, celery, etc.) you are safe to buy conventional non-organic produce, and some are very cheap. Potatoes are cheap (much more so than potato chips pound for pound), broccoli (a superfood) is cheap, and bananas are super-cheap!!! I could list more. Eating healthy won't necessarily break the bank. But it WILL save money on doctor's bills, prescriptions, time off work, etc..

Well I am suffering from fats ! Can you suggest me any juicy formula to help reduce my weight?

My favorite juice concoction, which I drink almost every day: A bunch of cilantro, a handful of spinach, 2 cucumbers, a stalk of celery, some lemon and a little ginger root. There is a serious noticeable difference in my mood and energy level if I skip juicing for several days. Once you get used to feeling that good, you don't want to go back.

I just wish cleaning all the individual components of the juicer every day wasn't such a pain. :( It's a small sacrifice though.

Always there is this concern about diabetics or near-diabetics when discussing juicing. I wish someone would advise hypoglycemics how to handle juicing. I mean some really good, accurate proven advice, not speculation.

Yes, Elle, I too wish there was a way to not have to clean & wash the juicing machine. This task is somewhat onerous after washing a whole sinkful of dishes...

Your recipe sounds so good (especially as cilantro is an anti-inflammatory). Of course, first I need to buy a juicer which I'm now looking for. Then I'll try this tasty recipe.

You need to add a slice of fresh ginger to all of these recipes. Nothing perks up juice more than a touch of ginger.

Awesome article, thanks Dr. Kim !!! I started juicing a couple of months ago, and I love it. I started with a spin basket juice extractor, and quickly learned they are not efficient, produce much waste, and are an absolute nightmare when it comes to cleanup. I now have an Omega, which I did not see on your recommended list. I would encourage you to check out the Omega and consider promoting it as well. Set up is easy, juicing is easy, it handles all the greens easily, and cleanup is a snap. It also has attachments for making pasta or bread sticks. It is priced very competitively. It is much quieter than the other piece of junk I had.

I also have the Omega juicer and I love it. Cleanup is a couple minutes max. The most time consuming part for me is prepping the vegetables.

There are many kinds of Omega juicers out there. What model do you have? I would really like a quicker clean up time! Thanks

Hi, Lynda, I have the Omega J8006. There are at least three I know of, and from the ones I've researched, I know the J8006 and VRT350 are highly rated. In fact, they're in the top 10 best juicers that I've looked up. It's a masticating juicer with a slow gear (I forget what that's called), so it is quieter and doesn't break down the nutrients or enzymes of the veggies. :)

How is a blender like Nutri Bullet for juicing...? Someone told me it is better as it does not separate the pulp to be discarded. I do not own either but am looking. THanks

Hi, the Nutri Bullet is more for blending. Please check out the differences of juicing and blending here:

Nutri Bullet is best for juicing.

Rather than juicing "gallons" I believe it is important to consume fresh juices quickly, even within 15 minutes. This is why chewing and swallowing whole foods is nutritous. Another benefit for a juicer / blender is that the foods are ground up finer than teeth are capable, but again the food needs to be consumed immediately to get the best nutrition. So forget buying juices at the store!

Interesting to suggest juicing bok choy that has never crossed my mind. I always have it in stir frys but never juiced it myself will have to give it a try :)

I went with the Omega as well, masticating or low speed juicing does not whip oxygen into your juice so the nutrients keep longer. I really got into juicing while I was liver cleansing, doing gb/liver flushes for a years time. Juicing=goodness, and a little fast never hurt anyone. Start slow, work your way up if you like, I used to fast all weekend, you don't have to do it all the time either. Other times just eat the vegetables lightly cooked, or also raw, chew up good. Also, when drinking your juice let your saliva work into it as well, chewing is often over looked when we toss our meals down in a hurried state, eating is more enjoyable when you eat well.

Thank you for the excellent primer on juicing. There is so much information out there, it's easy to get overwhelmed, and intimidated. Your instructions and caveats and clear, concise and direct and gave me the courage to start.

Of the citrus fruit family, only limes do not give me allergies. Recently I purchased a Nutribullet blaster, now I can tolerate kale and spinach along with my well cleaned vegetables and drink the resulting mix not just the juice. I wash all of my vegetables in food grade hydrogen peroxide (3.0%) 1/4 cup to 1 gallon of distilled water. The vegetables I cannot use immediately keep fresher and longer.

Good service.

I did a juice fast for 40 days 3 years ago and I am again on day 6 day of a juice fast 3 years later. First time around I saw so many benefits in my body by juice fasting. I must admit the first week was insane, I call it the food withdrawal week. First week consist of headaches, fatigue, sleepiness but week 2 the changes are priceless. I felt super energized, only needing 6 hours of sleep, I didn't feel sluggish or my eyes didn't feel that burning dry sensation when it was time to sleep plus I lost 36 lbs in 40 day!!!! Can't go wrong in trying this. I'm on day 6 and this second time around has been easier since I guess the body is use to it. I've lost 12 lbs in 6 days and I feel amazing, my breathing is back to normal as prior to starting the juice fast my breathing was heavy and short at times. This time I will doing the juice fast for 30 days and of course drink plenty of water as well. I think our bodies need rest from time to time, a break from all the toxins we consume everyday just kind of the same way our brain needs rest to rejuvenate its self.
