Eat any processed food? Ever crave carbs, drink coffee or diet soda, or use any artificial sweeteners for that matter? Do you sleep less than 8 hours a night? Have you ever taken ANY medications, wear makeup, use deodorant or clean your house with commercial cleaners? Ever feel stressed or sad?
If you answered “yes” to most, then Jennifer “JJ” Smith says you will benefit from detoxifying your body with the 10-Day Green Smoothie Cleanse, which she says could lead to weight loss and improved health and vitality. 
10-Day Green Smoothie Cleanse Claims
If you adhere strictly to the 10-Day Green Smoothie regime, you’ll lose 10 to 15 pounds, cravings will disappear, as will bloating, and your digestion will be improved. But that’s not all; on the JJ Smith 10-Day Green Smoothie Cleanse, the claim is, you’ll experience mental clarity, have increased energy and you will sleep better. 
Wow. Sign me up, right?
The 10-Day Green Smoothie Cleanse is a detox program where, if you do the full cleanse, you consume primarily smoothies—60 ounces a day—comprised of leafy green vegetables, fruits, and water. It’s best to drink a quarter every three hours or a third every four hours or so. Or sip throughout the day, as long as you get as close to that 60 ounces. Snack on crunchy veggies like carrots, cucumbers and celery or much on apples. And, include high-protein snacks like hard-boiled eggs, and a handful of raw, unsalted seeds or nuts. And don’t forget the water: a gallon a day in addition to the smoothie (don’t sub out smoothie for water; it’s not the same). And that is it. You are forbidden from eating refined sugars of any kind. No refined flours/carbs (white breads, pastas, rice, potatoes; you know the drill). No meat, and no dairy. Coffee, soda (even diet), and any alcohol are out. Absolutely nothing processed or fried.
If ten days of smoothies-only is just not doable, the modified plan has you eat one meal a day, though it must be a healthy one like a salad, sautéed vegetables, and a small piece of broiled or baked chicken or fish.
The 10-Day Green Smoothie Cleanse book has a ton of great tips from Smith, including shopping lists, 10-Day Green Smoothie cleanse recipes, and even advice on the type of blender you should use—and the latter is important because the idea is you want to “chew your smoothie.” Juicing takes out the fiber in fruits and vegetables and blending does not, she says. Although you should remove stems from all your greens because they are super bitter. Smith also lists brands that she suggests you use for ingredients like protein powder. She explains that the cleanse isn’t a panacea: your weight will fluctuate and it’s best to think of this “diet” as a way to cleanse your body and jump-start it to a better way of eating for life. 
Smith also wants you to “keep your bowels moving,” with at least one (or two or three) bowel movements every day. If you aren’t pooping at least once a day, she says you need to fix that by either drinking a saltwater flush—directions are in the book—or taking a good colon cleansing supplement. She strongly recommends Mag07 saying it will “work wonders.” 
And as an FYI, Mag07 is a superstar on Amazon where, with 1,777 reviews, it has an average rating of 4.7 stars. Wow. (I don’t know if she benefits from the sale of this product; probably does. But who cares?) 
But why a detox? Why a cleanse? JJ says one of the reasons we are overweight is our bodies are full of toxins:
When the body is overloaded with toxins, it transfers energy away from burning calories to work harder to detoxify the body. In other words, the body does not have the energy to burn calories. However, when the body is efficiently getting rid of toxins, the energy can be used to burn fat.
Simply put, traditional diets so often don’t work because they don’t address the toxic waste in the body. Counting calories does not detoxify and cleanse the body. Weight loss won’t be permanent if your body’s systems are sluggish or impacted with waste matter or toxins. You must first rid your body of toxins to ensure that your body can best metabolize the food you eat without leaving excess waste, which results in weight gain.
The following symptoms indicate the presence of excess toxins in the body: bloating, constipation, indigestion, low energy, fatigue/brain fog, depression, weight gain, chronic pain, infections, allergies, headaches, and gut/digestion problems.  (Page 2)
The theory is that if you:
- crave sweets, bread, pasta, white rice, and/or potatoes;
- eat processed foods;
- feel tired, fatigued, or sluggish or conversely anxious, antsy, or stressed;
- don’t get enough sleep;
- have breakouts;
- aren’t always “regular;”
- smoke (or ever smoked) or exposed to secondhand smoke;
- are overweight or have cellulite fat deposits;
- have a job where you’re exposed to environmental toxins;
- live in or near an urban area;
- ever been on antibiotics or birth control;
- and a list of about 20 other everyday life things,
You need a detox. JJ claims you’ll “significantly benefit from detoxifying your body, which could lead to weight loss and improved health and vitality. It is strongly recommended that you look into different ways to detoxify the body.”  (page 5)
Here’s the thing: she admits,
Although our bodies have the ability to eliminate toxins, it’s when the body gets overloaded with toxins that it stores them in fat cells. Fat cells don’t get broken down very easily, so they literally weigh down the body and make it bigger. As toxins accumulate, we begin to experience health problems like allergies, migraines, major diseases, and fatigue/low energy.  (page 5)
10-Day Green Smoothie Cleanse Ingredients
Nutrient-rich, hydrating and healthy, leafy veggies are at the heart of these smoothies, including vitamin- and mineral-rich arugula, beet greens, Chinese cabbage (bok choy), Swiss chard, collards, turnip, mustard and dandelion greens, kale (of course), lettuces with dark leaves, antioxidant-rich parsley, and the best of them all: spinach, packed with omega-3s, calcium, magnesium, and vitamins A, C, E, and K.
Then there’s the fruits—which JJ says do not have to be fresh; they can be frozen, like berries, mango, and peaches. Plus apples and bananas, and crunchy veggies like carrots and celery. 
Stevia is a permitted food and may be added to smoothies. Others permitted include flaxseed, seeds, eggs, raw, unsalted nuts, organic sea salt. and you may include a non-dairy/plant-based protein powder. 
JJ suggests brands, which you’ll find in the downloadable 10-Day Green Smoothie Cleanse .PDF file of her book online. It’s very easy to find.
The Science (or Lack Thereof) Behind the 10-Day Green Smoothie Cleanse
This is not astrophysics, people. Everything on the ingredient list for the 10-day cleanse is awesome, good-for-you food. And at only ten days, it’s probably safe. The question science has raised is this: “Do we need to detox our bodies when the body does it all by itself?” The jury is out on this one. Kind of.
MayoClinic.com says there is negligible evidence that detoxes or cleanses eliminate toxins from the body, rather, “the kidneys and liver are generally quite effective at filtering and eliminating most ingested toxins.” 
The Mayo Clinic does agree that people often claim to feel more focused, with more energy, healthier, and improved after a cleanse, but here’s why:
It may be due in part to the fact that a detox diet eliminates highly processed foods that have solid fats and added sugar. Simply avoiding these high-calorie low-nutrition foods for a few days may be part of why people feel better.
And most health professionals aren’t jumping up and down about colon cleansing, as is required with the 10-Day Green Smoothie Cleanse (and as is often the case with many different detox diets). Colon cleansing can cause cramping, bloating, nausea, and vomiting, and dehydration may also be an issue, the Mayo Clinic says. 
That all said, Katherine Zeratsky, R.D., L.D. says, “If you do choose to do a detox diet, you may want to use it as a way to jump-start making healthier food choices going forward every day.” 
Word on the Street about the 10-Day Green Smoothie Cleanse
My favorite part of this review is that I get to read “reader” reviews; JJ Smith’s book is what this diet is all about. So I went to GoodReads.com. There, from more than 3,000 reader ratings and 178 written reviews, Smith’s book earned a 4.1 star rating. 
The great thing is the vast majority of the 178 thoughtfully-written reviews were from people who read the book and did the cleanse. Real people like “Michele” (Mar 2016, 5 stars):
This smoothie cleanse actually works if you have the willpower to endure the first three days. I soldiered through the first ten days and it worked so well. I lost a pound a day. Around the fourth day, I literally felt light and free, like all of the world’s poisons has been washed from my body. I intend to keep doing this cleanse at least 3 to 4 times a year. My second go at it, I convinced my better half to try the cleanse. He loves it as well, losing 14 pounds in 10-Days. This is a great way to cleanse our bodies and lose weight! 
“Keliana” (Aug 2014, 5 stars) was confused by some of the inconsistent information in the book:
I like it but the author confuses me. First she says don’t eat corn, then lists popcorn as a snack. She talks about how animal protein is hard for the body to digest and at this point I think she is a vegetarian, then the recipes in the back if the book all contain meat. I am a vegetarian and no way am I eating those things. She also says it’s not a starvation diet, which to me is exactly what felt like. They said it would get easier as u go but for me hunger just got worse. I am happy with the 5 lbs I lost but wish it was more like everyone else is claiming to lose. … Overall I liked it but I never want to see another smoothie again in my life. 
“Kristen” (Jul 2014, 3 stars), who was a little bit critical, was also sort of a fan:
There was a lot of questionable nutritional advice. I don’t think people need cleanses. Our bodies will cleanse themselves as soon as we stop putting poisons into them. The advice wasn’t all bad, but I wouldn’t refer people to this book for dietary information. However, I still rated this book three stars and would recommend it to others because it has a lot of great smoothie recipes and ideas that don’t involve difficult-to-find ingredients. 
To get a big-picture look at 10-Day Green Smoothie Cleanse reviews, I also stopped by to check in with Amazon and Walmart.
At Walmart.com, there were 56 reviews and an overall rating of 4.9 out of 5 stars. These folks loved the cleanse.
“Slady32” (Apr 2017, 5 stars) says,
“If you follow the program in this book, you can lose the weight. It is not a diet, but a lifestyle change. This book helps you with the changes you need. to make. I have lost weight by following the plan.”
And “Asiaboo” (Mar 2017), who also gave the cleanse a 5-star review, says it “works wonders I lost 10 pounds in 10-Days.” 
I saved the big guns for last. On Amazon, JJ Smith’s 10-Day Green Smoothie Cleanse book is an official “Amazon #1 Bestseller” and has 8,345 reviews with an overall average of 4.7 stars (81% 5-star). I have never seen any product with as many positive reviews. Ever.
One “Amazon Customer” (Aug 2017, 5 stars) had this to say:
I’ve tried everything possible. But this 10-day green smoothie cleanse is EVERYTHING. My husband and I start Monday of this week. We are on day 3. He has lost 6 pounds and I have lost 4. Believe it or not. Thank you JJ Smith. 
“Esmeralda Luv” (Aug 2017, 5 stars) says,
Easy to follow. Realistic ingredients. I lost 10 pounds! I used this to kick start the new eating habits my doctor recommended. The smoothie program was a break from my everyday not-so-great eating habits. When it was over, I began following my new way of eating (necessary due to my age changing body and my doctor’s recommendations). I don’t have the negative cravings I had prior to the cleanse. It’s like a fresh start to a better me. 
To be fair and balanced, I had to find a couple of real naysayers on Amazon, like verified and badge-wearing Amazon user “Knitting Ninja” (Jun 2017, 1 star), who says,
The author, who is a certified nutritionist not a registered dietician (for more information on the differences between the two search Google) cites no research to support her claims and some of the articles I have read that did cite scientific research directly contradicts what the author has said. I purchased this book because she appeared on Dr. Oz but in the future I will do my own research. 
Okay, but that’s not a critique of the cleanse itself. Hold on. Be right back.
Found one. “Kolleen Kholus” (May 2015, 1 star) says to “Proceed with caution.”
I followed the program to a T, and I did not lose any weight. The smoothies were not green, as the fruit in the recipes made them the color of the fruit. I was very tired throughout the cleanse. I think perhaps the fruit in the recipes was for me like getting a direct shot of sugar. I would not recommend this program for anyone who has issues with sugar. 
The Bottom Line: Is the 10-Day Green Smoothie Cleanse Worth a Try?
Yes. The best way to detox your body is arguably through good nutrition. But good nutrition that is not a diet, cleanse or temporary fix has to be—or become—a way of life. Enjoy guilty pleasures on occasion and don’t deprive or restrict yourself too much, because that will backfire. I have been there. Am there. I know this. It’s a fact.
I agree with the Mayo Clinic: if you simply need a jumpstart, or a foundation from which to build a new way of eating to live and not living to eat, the 10-Day Green Smoothie Cleanse sounds like a plan.
