The Smoothie Diet is a 21-day rapid weight loss program created by health coach Drew Sgoutas. It replaces two daily meals with nutrient-rich smoothies while keeping one balanced whole-food meal. Based on user reviews, most people lose between 5 and 12 pounds in the first week. It is generally safe for healthy adults, though some report hunger and low energy in the first few days.
What Is The Smoothie Diet?

How Does The Smoothie Diet Work?
The program works on a straightforward principle — by replacing calorie-dense processed meals with low-calorie, high-nutrient smoothies, your body enters a natural calorie deficit while still receiving the vitamins, minerals, and fibre it needs to function properly.
Each day you drink two smoothies — one for breakfast and one for lunch — and eat one balanced whole-food meal in the evening. The smoothies are designed to keep you feeling full by combining fibre-rich fruits and vegetables with healthy fats and protein sources. One day each week is designated as a flex day, allowing you to eat three normal meals to prevent the metabolic slowdown associated with prolonged calorie restriction.

The Smoothie Diet for Weight Loss: What Do Real Users Say?
User feedback on The Smoothie Diet is broadly positive, particularly among people who have struggled with traditional calorie-counting diets. The most common results reported across verified reviews include noticeable weight loss within the first week, significantly reduced sugar cravings after day three or four, and improved energy levels once the body adjusts past the initial transition period.
Most users in the US and UK report losing between 8 and 21 pounds over the full 21-day program, with results varying based on starting weight, activity level, and how closely the plan is followed. The program tends to work best for people who are consistent with both the smoothies and the evening meal guidelines.
The Smoothie Diet Complaints: What Are People Saying?
No program is without its critics, and The Smoothie Diet is no exception. The most frequently raised complaints from real users include:
- Hunger in the first 2 to 3 days — the body takes time to adjust to liquid meals, and some people find the smoothies less filling than a solid breakfast initially
- Repetitive flavours — while 36 recipes sounds like plenty, some users feel the rotation becomes predictable by week two
- Requires a blender — this sounds obvious but is worth noting; without a good quality blender, the texture of some smoothies is less enjoyable
- Not suitable for very active lifestyles — people with high daily energy demands such as manual workers or serious athletes may find the calorie level too low
These are genuine complaints worth considering, but none of them represents a fundamental flaw in the program itself.
The Smoothie Diet Side Effects: Is It Safe?
For most healthy adults, The Smoothie Diet is safe when followed as directed. However, some users do experience mild side effects during the first few days as the body adjusts to a significant change in diet:
- Mild headaches — often caused by reduced caffeine or sugar intake
- Low energy in days one to three — common during any calorie reduction phase
- Digestive changes — increased fibre from fruits and vegetables can cause temporary bloating
These effects are typically short-lived and resolve on their own by day four or five. The program is not recommended for pregnant or breastfeeding women, people with diabetes or blood sugar conditions, or anyone with a history of eating disorders. If you have an existing medical condition, consult your doctor before starting.
