Three weeks. Two smoothies a day. One structured plan.
That’s the whole 21 Day Smoothie Diet Plan. And if you’ve landed here, you’re probably wondering whether the 21 Day Smoothie Diet actually delivers on it or quietly joins the long list of programmes that sounded great until they didn’t.
Most smoothie plans fail for one of two reasons:
- They’re either nutritionally thin (basically flavoured water with fruit), or
- They’re so complicated that no one sticks past day four.
The 21 Day Smoothie Diet tries to solve both problems. Whether it succeeds depends a lot on who’s following it, and whether their expectations are realistic going in.
We went through the full programme, the real user reviews, the complaints, and the science behind meal replacement for weight loss. Here’s our honest take.

What Is the 21 Day Smoothie Diet?
The 21 Day Smoothie Diet is a digital weight loss programme — not a supplement, not a powder, not a subscription box. You pay once, download a PDF guide, and start the same day.
It was created by Drew Sgoutas, a certified health coach who originally developed it for his private clients.
The core method: replace breakfast and lunch with two nutrient-dense smoothies each day, eat one balanced whole-food dinner, and follow a specific schedule across three weeks designed to keep results moving.
The programme includes 36+ smoothie recipes, week-by-week shopping lists, a smoothie prep guide, and two free bonus programmes. Everything you need to run the full 21 days is included — no upsells, no ongoing subscription, no special equipment beyond a basic blender.
How the Programme Actually Works — Week by Week
This is what most reviews skip, and it’s the most important thing to understand before buying.
The 21 Day Smoothie Diet isn’t just “drink smoothies for three weeks.” The sequence of recipes and their nutritional composition is deliberately varied across each week. That’s the mechanism Drew calls the Custom 3-Week Weight Loss Schedule — and it’s genuinely what separates this from a generic smoothie recipe book.
Week 1: Focuses on transition, easing your system away from processed foods, stabilising blood sugar, and reducing cravings. The smoothies in this phase are designed to be filling and satisfying to prevent the energy crashes that derail most diets in the first few days.
Week 2: Shifts the nutrient ratios to accelerate fat-burning. Fibre increases, natural sugar is more carefully managed, and ingredient combinations are tuned for metabolic momentum built from week one.
Week 3: consolidates and maintains. Recipes in this phase are designed to support continued weight loss while preparing your habits for what comes after the programme, which is the question most people have and almost nobody answers. (We address it in the FAQ below.)
This week-by-week structure is backed by a principle well-supported in nutritional research: structured meal replacement, when nutritionally adequate, produces meaningful short-term weight loss compared to standard dieting.
What You Actually Eat in a Day
Here’s a realistic picture of a day on the programme — because “two smoothies and a dinner” tells you almost nothing useful.
| Meal | What You Eat | Details | Approx. Calories |
|---|---|---|---|
| Breakfast | Meal-replacement smoothie | Made with leafy greens, frozen fruit, a protein source (Greek yogurt, nut butter, or plant-based protein), fibre, and healthy fats. Designed to keep you full for 3–4 hours. | 300–400 calories |
| Lunch | Second smoothie | Uses a different recipe and nutrient profile than breakfast. Recipes rotate daily with different ingredients, textures, and flavors to provide variety. | Varies by recipe |
| Snacks | Low-calorie whole foods | Allowed between smoothies. The program provides an approved snack list. | Low-calorie |
| Dinner | Balanced solid meal | Real food, not a smoothie. Includes lean protein, vegetables, and complex carbohydrates. No calorie counting required; the guide provides approved meal ideas. | Varies by meal |
What You Get — Full Contents
📦 Everything Included in the 21 Day Smoothie Diet
- The Core 21-Day Programme: The full weight loss guide with the 3-week schedule, 36+ smoothie recipes, weekly shopping lists, and prep guide. The same programme Drew uses with his private coaching clients.
- Bonus #1 — The 3-Day Smoothie Detox (Free): A standalone 3-day reset programme you can use before the main plan to clear your system and prepare for better results. Also useful any time you need a quick reset — after holidays, a bad eating week, or going off track. One client lost 3 lbs in 3 days on this alone.
- Bonus #2 — Quick-Start Guide (Free): A condensed, print-ready version of the core guide — the 3-week schedule, shopping lists, and recipes in one fast-reference document. For people who want to start today without reading the full guide first.
What You Can Realistically Expect
- Improved relationship with food: Three weeks of structured eating resets portion awareness and reduces mindless snacking habits — benefits that outlast the programme itself.
- Faster initial weight loss: Replacing two calorie-dense meals with nutrient-rich smoothies creates a natural calorie deficit — most users report visible results within the first 7 days.
- Reduced bloating and digestive discomfort: The high fibre content from fruits and vegetables helps clear out sluggish digestion quickly — often noticeable within the first few days.
- More stable energy throughout the day: No heavy processed meals means no post-lunch energy crashes. Most users report feeling lighter and more alert by week two.
- Reduced sugar cravings: The structured schedule is specifically designed to break the processed sugar cycle — by week three, most users report significantly fewer cravings.
- Clearer skin: Multiple users mention this unprompted — a common secondary benefit of increased hydration, reduced processed food intake, and higher antioxidant consumption.
- Better sleep quality: Lower inflammation from a cleaner diet often translates into more restful sleep — another benefit users mention without being prompted.
21 Day Smoothie Diet Reviews & User Complaints
“After only 1 week on the Smoothie Diet I weighed myself and realised I had lost 8 pounds. I feel better and more confident than I have in a very long time. I don’t have to suck in my stomach to button my pants anymore.”
“I have just completed the Smoothie Diet — in a word, FAB. After only a few days I felt brilliant, full of energy. The smoothies are tasty and filling and never boring. I lost 14 pounds and wake up every day more confident.”
“I’ve been trying forever to lose the last 10–15 lbs. In 21 days my love handles are gone, I feel confident, and people have noticed. I couldn’t be happier. I recommend this to anyone looking to lose a little or a lot.”
“My skin is glowing and I have more energy than I’ve had in years. This is more of a life overhaul than a diet. The only thing I’d say is be prepared — week one is an adjustment. Stick with it. It’s worth it.”
The clearest pattern across reviews: energy improvements are the first thing people notice, usually within days. Visible weight loss follows by the end of week one for most users, with the biggest results reported at the 21-day mark.
We looked for the negatives, too. Here’s what real critics say:
“Week one was hard. I was hungry by mid-afternoon and the smoothies took longer to prepare than I expected. By week two it was much easier, but the first few days were a real adjustment. Would have helped to know that going in.”
“I lost weight during the 21 days but gained about half of it back in the following two weeks because the guide doesn’t really explain what to do after. There’s a bit about it but it felt vague. Would have liked a clearer transition plan.”
Is the 21 Day Smoothie Diet Legit?
Straight answer: yes, it’s a legitimate programme. Here’s the evidence:
- Created by a certified health coach with documented client results
- Backed by a clear 60-day money-back guarantee — full refund, no questions
- The meal replacement approach it uses is well-supported in nutrition research for short-term weight loss
- Tens of thousands of verified buyers with publicly available testimonials
The “scam” concern most often comes from people who expected permanent results from a 21-day programme — or who didn’t follow the plan consistently. No weight loss programme produces lasting results without some ongoing lifestyle effort. This one gives you the tools. Whether they stick is up to the person using them.

Who It’s Best For — and Who Should Skip It
Best fit if you:
- Want a structured, guided approach rather than figuring it out yourself
- Have 10–40+ lbs to lose and want to see fast, early results that motivate you to continue
- Are you comfortable replacing two meals daily with blended food for three weeks
- Want a low-cost, no-subscription solution with a safety net guarantee
Probably not right if you:
- Have diabetes, a metabolic condition, or are on medication that requires consistent carbohydrate intake, consult your doctor first
- Are pregnant or breastfeeding

- Strongly dislike smoothies or blended food in any form
21 Day Smoothie Diet — HBMag Editorial Score
Our Final Verdict on the 21 Day Smoothie Diet
The 21 Day Smoothie Diet is a well-structured, genuinely affordable weight loss programme that does what it promises for most people who follow it. The week-by-week progression is smarter than it looks on the surface, the recipes are practical, and the results reported by real users are consistent and credible.
Its limitation is the post-programme phase — it’s strong on getting you through 21 days and lighter on what comes next. That’s worth knowing going in. Plan your transition before you finish, not after.
At $27 with a 60-day refund guarantee and two useful free bonuses, there is almost no financial reason not to try it if you’re genuinely committed to making a change. The 3-Day Smoothie Detox alone is worth the price of entry as a standalone reset.
Frequently Asked Questions
What is the 21 Day Smoothie Diet?
It’s a digital weight loss programme created by certified health coach Drew Sgoutas. You replace breakfast and lunch with two nutritionally designed smoothies each day, eat one balanced whole-food dinner, and follow a specific 3-week schedule of recipes and shopping lists. It costs $27, downloads instantly, and comes with two free bonuses.
Does the smoothie diet actually work?
For most consistent followers, yes — especially in the short term. The meal replacement approach reduces calorie intake while maintaining nutrient density, and the structured week-by-week schedule prevents the adaptation plateau that derails many diets. Real user results of 8–14 lbs in 21 days are commonly reported. Individual results vary based on starting weight, adherence, and lifestyle factors.
Is the 21 Day Smoothie Diet legit or a scam?
It’s legitimate. Sold through ClickBank with a 60-day money-back guarantee, created by a certified health coach with documented client results, and backed by nutrition science supporting structured meal replacement for weight loss. The “scam” label most often comes from people with unrealistic expectations or who didn’t follow the plan.
How much does the 21 Day Smoothie Diet cost?
Currently $27 — discounted from $47. This is a one-time payment with no subscriptions, no recurring charges, and no physical shipping. You get instant PDF access plus two free bonus programmes.
Is there a free PDF version of the 21 Day Smoothie Diet plan?
Not legitimately. Free versions circulating online are either incomplete, pirated, or fake. The full programme — including the week-by-week schedule, 36+ recipes, shopping lists, and bonuses — is only available through the official website for $27.
What happens after the 21 days? Will I gain the weight back?
This is the most important question and the one most reviews skip. The programme includes guidance on continuing beyond 21 days by cycling through the recipes and maintaining the smoothie-replacement habit for one or two meals daily. Weight regain is most common in people who return entirely to their pre-programme eating habits. The goal of the 21 days is to reset your palate, break sugar dependency, and establish a baseline — what you build on that depends on the choices you make after.
How long should you use a smoothie diet?
The structured programme is 21 days. Many users continue past that by cycling through the recipes and using one smoothie per day as a long-term meal replacement habit. Drew designs the programme to be extendable — you’re not limited to three weeks if you want to keep going.
Do I need an expensive blender?
No. The recipes are designed for everyday blenders. A basic $30–$50 blender handles everything in the programme. Ingredients are standard supermarket items — the weekly shopping lists tell you exactly what to buy.
