About the Creator

The author of the 21-Day Smoothie Diet Program is a certified fitness coach and nutritional expert Drew Sgoutas. Based in Boise, Idaho, he is passionate about helping others boost their health and well-being for better quality of life.

How Does It Work and What Are the Health Benefits?

The 21 Day Smoothie Diet recommends that you replace 2 of your 3 daily meals with a healthy smoothie according to the recipes provided. The third meal includes a regular, healthy regimen according to a recommended list of foods to eat and avoid.

Examples of foods that you should include are whole grains, fruits and vegetables, lean meat, fish, eggs, nuts and seeds, herbs and spices, and Greek yogurt. The Smoothie Diet stipulates that you should avoid refined grains, processed foods, and beverages with added sugar, similar to the Golo Diet.

Evidence published in the British Medical Journal indicates that diets high in processed foods increase the risk of cardiovascular disease and may decrease longevity [1].

The Smoothie Diet Detox plan involves replacing all three daily meals with smoothies for 3 days in a row, which is only meant as an occasional reset method.

The primary weight loss mechanism of the 21 Day Smoothie Diet is promoting a calorie deficit, and Drew Sgoutas recommends that you keep to 1500 calories daily. There is quite a bit of evidence supporting the effectiveness of this technique as a weight loss method.

A long-term study published in the New England Journal of Medicine by Frank Sachs, et al looked at the impact of several different diets and concluded that a low-calorie regimen led to the most meaningful weight loss [2].

Sachs explained,

This is important information for physicians, dieticians, and adults, who should focus weight loss approaches on reducing calorie intake.

The Smoothie Diet is high in fiber, which helps suppress hunger, so you take in fewer calories. It also helps lower blood sugar and cleanse the colon to promote healthy bowel movements and ease issues like gas and bloating, as we said in our review of Colon Broom.

A 6-month study of obese and overweight adults on a low-calorie diet by Derek C Miketinas, et al published in The Journal of Nutrition found that higher fiber consumption promoted weight loss and adherence to the diet [3].

The Smoothie Diet is high in nutrients that boost general health and antioxidants that strengthen the immune system by killing free radicals and lowering oxidative stress.

A review and discussion published by Daniyal Abdali, et al in Medical Principles and Practice concluded that antioxidants may be a helpful addition to a weight loss diet [4].

Verdict: According to the evidence a low calorie, high fiber diet may suppress appetite, promote weight loss, and offer other health benefits.

What Do the Reviews Say?

We give the Smoothie Diet Plan to Lose Weight program a high rating of 4.6 out of 5 stars. While we wouldn’t recommend it as a long-term diet, it’s an excellent and delicious way to start a weight loss journey and periodically boost your progress.

Some product reviewers critique the diet for having too little protein and too much sugar, however, we disagree as we think that as a short-term regimen, it has numerous advantages.

There are some excellent testimonials including before and after pictures on the official website. In addition, 50 users on Goodreads rate the program 4.28 out of 5 stars. The lowest rating on Goodreads is 3 stars, and none of the actual comments are critical.

One of the top 5-star comments is from Melissa Lambert, who writes in part about her 21 Day Smoothie Diet results:

Great book with great tips. Lost 30 pounds with smoothies supplementing my diet over 1.5 years. Love most of the smoothies and now have enough tips to create my own.

Easy to follow recipes and most are convenient. Four of my coworkers and two friends also bought the book because they saw my results. If you’re into clean, healthy eating, you can get all your nutrients in a well-made smoothie that fills you up. –Melissa Lambert

Verdict: While reviewers vary in their opinions of the diet, many of the customer reviews are very enthusiastic about the regimen and their 21 Day Smoothie Diet results.


In conclusion, we think that the 21-Day Smoothie Diet program is a delicious, high-nutrient short-term regimen that offers weight loss and other health benefits like improving digestion, balancing blood sugar levels, boosting energy, and promoting healthier skin.

The 21 Day Smoothie Diet review feedback from people who tried the diet is mostly highly positive, with many saying it really boosted their weight loss progress and offered other benefits like a glowing complexion.

Developed by fitness and nutrition expert Drew Sgoutas, the Smoothie Diet is a safe way to boost your weight loss efforts over the short term, and you can repeat it periodically to help with maintenance. At the very low current price of the program, you have nothing to lose!

Highly recommend it to anyone looking for a comprehensive health boost.
