Juice cleanses (along with fresh juices in general) have become a go-to for health nuts and normies alike. They’re taken up by many people looking to lose weight, but they’re most often used as a ‘reset’ button that detoxes the body. Some health geeks swear by juice cleanses after a long weekend or vacation of imbibing, or simply when you get that occasional sluggish, bloated feeling.

Juice cleanses are a new phenomenon, so a little skepticism is warranted if you haven’t done one yet. We’re here to help you fully understand this health trend and get you on track for a refreshing, health-boosting juice cleanse.

Benefits of Juice Cleanses

Most people who have embarked on a juice cleanse can attest to the benefits, but researchers seem to be finding more and more science behind these benefits. Here is the shortlist of juice cleanse benefits:

  • More energy
  • Better sleep
  • Better digestive health
  • Weight loss
  • Heart health
  • Better skin

These benefits are fairly wide-ranging, so let’s break them down a little bit.

The weight loss associated with juice cleanses is both straightforward and confusing. Obviously, you’ll probably be in a calorie deficit when you’re only consuming juices. However, juice cleanses can also be helpful with the mental side of weight loss, which is the real battle for many people looking to slim down. You’ll need to be tough with yourself, and you’ll need to cut out unhealthy junk food and sugar while doing the juice cleanse. After changing your habits with the cleanse, it might be easier to stay off the junk once you’re done.

The other primary benefit is improved digestive health, which might be the root of many other benefits. Juice cleanses give your gut and digestive tract a rest, which may heal and recharge the organs. This results in better vitamin and nutrient retention once the cleanse is over, providing energy, reducing acne and improving sleep.

How Juice Cleanses Work

Juice cleanses typically come in one, three, or seven-day packages, but go as high as 10-day package for real pros. Each day consists of several juices that are often tailored to different times of day (i.e. an energy-boosting blend for breakfast and a relaxing juice before bed). Some juice cleanse programs also suggest incorporating light vegetarian or vegan meals as well.

During a juice cleanse you should be limiting strenuous exercise and enjoying stress-free activities like nature walks, yoga, or writing. But before you jump headfirst into a juice cleanse, health experts suggest a period of preparation. After eating poorly, drinking alcohol, getting poor sleep, and being stressed, a sudden juice cleanse can be an uncomfortable shock to the body. An effective two-day preparation period and a gradual two-day finish not only makes the actual cleanse easier to handle but also much more effective.

For these two days on both ends of the juice cleanse, replace unhealthy foods, drinks and activities with healthy nutrition and light exercise. This means replacing animal products, alcohol, sugar and coffee with green tea, fruit, lentils and rice (click here for the full list). During these two days, you should also try to avoid stress as much as possible and get a good night’s sleep.

How to Pick a Juice Cleanse

There are now dozens of juice cleanse programs to choose from, so you’ll need to research a few before deciding. We’ve combed the web for some of the best juice cleanses, but there are still some decisions you’ll need to make before choosing.

The first choice is easy: how long do you want your juice to cleanse to be? The typical length is three days because it’s effective but not too challenging. One-day cleanses are great for beginners or anyone that just wants a quick detox, say, on a Saturday after a stressful week. Seven- and ten-day cleanses should only be used by people who’ve done a cleanse before.

You’ll also need to decide if you want ready-to-drink juices sent to your door or powder packets that you mix with water, orange juice or nut milk. There is also the option of a completely DIY juice recipe book. Powder packets and DIY options are usually cheaper and more convenient if you’re having juices while at work or on the road, but ready-to-drink juices make the whole process easier.

How to Prepare for a Juice Cleanse

The last piece of the puzzle is preparing for a juice cleanse. I would not recommend diving headfirst into three days of no eating with no prep whatsoever. None of the Spy editors are doctors or medical professionals, but we do recommend talking to one before embarking on a cleanse to make sure it’s a healthy choice for you and your body.

In order to prepare for a cleanse you’re going to want to embark on a pre-cleanse to prep your body so you don’t end up with uncontrollable cravings, sickness or lethargy. You’ll probably experience some of these regardless, but to give yourself the best shot at success, especially if you’re a newbie, it’s best to cut back on certain things 2-5 days before your cleanse starts.

This list of things includes — caffeine, processed foods, animal products in general and refined sugar. You should also start eating more fruits and vegetables and drinking more water. Sound straightforward? Don’t worry, it is.

Ready to take the plunge? Here are the best juice cleanses to try right now.


1. Pressed Juicery Cleanse 2


Pressed Juicery has become one of the biggest fresh juice brands in the country. They’ve been so successful because they make simple, healthy, and most importantly, tasty juices. This cleanse is their most popular because it’s effective for pros yet approachable enough for beginners. It’s by far the favorite amongst Spy readers on this list for its quality, taste and effectiveness. The cleanse consists of six juices per day that you drink every two hours. Each juice is made for a different time of day. This keeps your energy and mood as high as possible throughout the cleanse. And unlike most other cleanses, you can select how many days you want this one to last. Three days is an average cleanse, but definitely try five or even seven days if you’re up to it.

10. 10-Day Green Smoothie Cleanse


One of the healthiest (and most affordable) ways to nail a juice cleanse is by making your own smoothies at home. This book offers detailed instructions for shopping, making the smoothies and properly consuming them. The cleanse is one of the most intense at 10 days long, but because you’re using fresh ingredients, you’ll get slightly more nutrients. And with this cleanse the payoff is big, as you should lose 10-15 pounds in just 10 days. We were skeptical of this claim at first, but the book’s almost 10,000 reviews and a 4.7/5 star rating should help put you at ease. If you love smoothies and green tea, this may be the DIY juice cleanse you’ve been looking for.
