The Smoothie Diet Review 2026: Why We Passed
This Smoothie Diet review is a little different from most you’ll find in Google. We originally drafted a standard review of Drew Sgoutas’ 21-day smoothie program for this site — and then decided not to recommend it. Below is the honest breakdown: what the program actually is, what the science says about meal-replacement plans, why it didn’t clear our evidence bar, and what we suggest instead. As always: affiliate disclosure and medical disclaimer apply.
| The Smoothie Diet | At a Glance |
|---|---|
| What it is | Digital 21-day plan: replace 2 meals/day with smoothies, keep 1 solid meal + snacks |
| Creator | Drew Sgoutas, certified health coach (not a registered dietitian or physician) |
| Format | PDF/e-book bundle, one-time purchase, sold through ClickBank with a 60-day refund window |
| What’s real | More produce and fiber, simple structure, built-in calorie deficit for many people |
| Why we passed | Marketing leans on dramatic short-term weight-loss framing; no coaching or accountability; results depend entirely on the calorie deficit, not the smoothie format |
| Our verdict | Not recommended as a purchase — see the alternative we do recommend below |
What The Smoothie Diet Actually Is
The Smoothie Diet is a digital 21-day program created by Drew Sgoutas, a certified health coach. You replace two meals a day with a smoothie made from provided recipes, keep one regular “sensible” meal, and add one or two snacks. It ships as a downloadable e-book bundle — the main 21-day plan with 30+ recipes, weekly shopping lists, and a short getting-started guide. There is no app, no coaching, no community, and no physical product: you follow the PDFs on your own.
Does Replacing Meals With Smoothies Work? What the Science Says
Here’s the fair part: meal-replacement approaches are not pseudoscience. A 2019 systematic review and meta-analysis found that structured meal-replacement plans produced meaningfully greater weight loss at one year than comparable diets without them (Astbury et al., Obesity Reviews, PMID 30675990). Swapping a typical fast-food lunch for a portion-controlled smoothie usually creates a calorie deficit, and more fruit, vegetables, and fiber is hard to argue with.
But the mechanism is the deficit — not the blender. And liquid calories have a real downside: chewing and food texture contribute to satiety, and higher-protein solid meals in particular are consistently linked to better appetite control during weight loss (Leidy et al., American Journal of Clinical Nutrition, PMID 25926512). Fruit-forward smoothies are also easy to overload with sugar. In other words: the format can work for people who love smoothies, but nothing about it is metabolically special.

Why We Decided Not to Recommend It
- The marketing outruns the evidence. The sales page leans on dramatic short-term transformations. Rapid early weight change on a low-calorie liquid plan is mostly water and glycogen — presenting it as typical fat loss doesn’t meet the standard we hold products to on this site.
- You’re paying for structure, not substance. The core content — produce-heavy smoothie recipes and shopping lists — is genuinely fine, but it’s information you can assemble for free; there’s no coaching, community, or accountability included to justify the price for most people.
- The “metabolism reset” framing is marketing language. Rotating recipes week to week keeps the plan from getting boring — it does not stop your metabolism from “adapting” to a smoothie, because that’s not how metabolic adaptation works.
- Poor fit for a lot of readers. Anyone who dislikes liquid meals, has a history of disordered eating, or manages a condition like diabetes that requires closer control of meal composition should not be steered into a 2-shakes-a-day template by a sales page.
None of this makes The Smoothie Diet a scam — it’s a real product with a real 60-day ClickBank refund policy. It simply didn’t clear the bar we use for products we’re willing to put our name behind. We apply that same bar in our berberine vs. metabolism tonics breakdown.
What We Recommend Instead: Eat Stop Eat
If what attracted you to The Smoothie Diet was a simple, structured way to eat less without counting every calorie, the approach we do stand behind is Eat Stop Eat by Brad Pilon — a straightforward intermittent-fasting book by an author with a master’s degree in applied human nutrition. Instead of replacing meals with liquid ones, you simply take one or two 24-hour breaks from eating per week and eat normally the rest of the time. It’s flexible, it doesn’t demonize any food, and the fasting-and-metabolism research it’s built on is discussed honestly, limitations included. Read our full Eat Stop Eat review for the complete breakdown.

FAQ: The Smoothie Diet
Is The Smoothie Diet legit or a scam?
It’s a real digital product with a real 60-day ClickBank refund policy, so it isn’t a scam in the fraud sense. Our issue is value and framing: the marketing oversells what a smoothie format can do, and the substance is information most people can assemble for free.
Can you lose weight on The Smoothie Diet?
Many people would, at least short-term, because replacing two meals with portion-controlled smoothies typically creates a calorie deficit — the same mechanism behind every diet that works. Meal-replacement plans do show better one-year results than unstructured diets in research, but the effect comes from the deficit and the structure, not from smoothies being special.
Why don’t you recommend it if meal replacement works?
Because the sales page leans on dramatic transformation framing, liquid meals suit fewer people than the marketing implies, and the package includes no coaching or accountability. When we recommend a paid product, the marketing has to be as honest as the science — this one didn’t clear that bar.
What’s a better alternative to The Smoothie Diet?
For structure without liquid meals, we recommend Eat Stop Eat — Brad Pilon’s flexible intermittent-fasting approach. For free options, whole-food high-protein meals plus strength training remain the best-evidenced combination for fat loss that preserves muscle.
