The Smoothie Diet (21-Day Program) Review

A 21-day meal-replacement plan built around structured smoothie recipes.

4.2/5 Recommended By Reviews-Supplements Editorial Team Updated August 2026

Bottom line: The Smoothie Diet is one of the more honest weight-loss products we've reviewed: it works through a sensible calorie deficit and more produce, not hype. For a low one-time price you get structure that makes eating less genuinely easier for three weeks. Treat it as a kick-start, build lasting habits afterward, and it's easy to recommend.

What is The Smoothie Diet (21-Day Program)?

The Smoothie Diet is a digital weight-loss program by health coach Drew Sgoutas, not a supplement. It provides a 21-day plan in which you replace two of three daily meals with specific smoothie recipes while eating one balanced whole-food meal.

As a program, it's refreshingly sensible: the results come from a structured calorie deficit and more fruits and vegetables, not from any magic ingredient. That honesty, plus the low price and detailed shopping lists, make it one of the stronger picks in the weight category.

How it works

The plan works through simple, well-established mechanics: replacing higher-calorie meals with nutrient-dense, portion-controlled smoothies creates a calorie deficit (around 1,500 kcal/day), which drives weight loss. Structure — set recipes, shopping lists, a 3-day detox, and a quick-start guide — is what makes it easier to stick to than 'just eat less.'
