Low Calorie Smoothie King: 13 Options Rated By Nutritionist

Despite many of the Smoothie King drinks being packed full of calories and sugar, there are some options that are lower in calories than others.  

The 13 lowest-calorie smoothies at Smoothie King are: 

• Slim-N-Trim Strawberry (150 calories)  
• Lean1 Strawberry (200 calories) 
• Pure Recharge Mango Strawberry (210 calories) 
• Gladiator Strawberry (220 calories)  
• Angel Food Slim (220 calories) 
• The Shredder Chocolate (230 calories)

• Metabolism Boost Strawberry Pineapple (270 calories) 
• Greek Yogurt Pineapple Mango (280 calories) 
• MangoFest (300 calories) 
• Veggie Lemon Ginger Spinach (310 calories) 

Below, I’m going to explain how you can customize each of these drinks to get them even lower calories, as well as explain a few smoothies that you should avoid if you want to watch your calories.

What Is Considered A Low-Calorie Smoothie At Smoothie King? 

A smoothie that has fewer than 300 calories can be classed as a low-calorie option at Smoothie King. 

What Increases Calories In A Smoothie At Smoothie King?  

The main things that increase the calorie content at Smoothie King are: 

• Fruits 
• Nutritional Enhancers 
• Fruit Juice Blends  

Fruits 

Depending on the fruits that are used in the smoothie, the calories will be different. Most of the smoothies at Smoothie King contain at least one fruit but some have multiple different fruits. 

If you’re trying to reduce your calorie intake, go for the smoothies that contain more veggies than fruits, as vegetables are generally lower calories than fruits.

Alternatively, stick to the smoothies that mainly consist of berries instead of banana or passionfruit, because berries are lower in calories and sugar. 

Here’s a list of the common fruits at Smoothie King and their calories:

Nutritional Enhancers 

Smoothie King offers a range of nutritional enhancers that can be added to your drink, including Muscle Builder, Whey Protein, Gladiator Protein, and Keto Protein. 

Although the “Nutritional Enhancers” add extra nutrients to the smoothie, such as protein, creatine monohydrate, or collagen peptides, they aren’t calorie-free. 

For example, the Keto Protein contains 70 calories per serving, whereas the whey protein has 30 calories.

So I’m not suggesting skipping the “Nutritional Enhancers”, but definitely be mindful of the calories each one has.

Here’s a summary of the lowest to highest calorie enhancers at Smoothie King:

Fruit Juice Blends 

Many of the Smoothie King drinks contain a mixture of fruits and fruit juice blends. This was shocking to me because of how high-calorie the fruit juice blends can be.

The fruit juice blends enhance the flavor and sweetness of the drink but they also add to the calories. 

For example, the Apple Pineapple Juice Blend contains 130 calories and 31 grams of carbohydrates. 

To save calories, you can always swap the fruit juices with water, which contains no calories.

Alternatively, you can ask for “half water” and “half fruit juice”, which will cut the calories in half, but still maintain most of the sweetness/flavor of the smoothie.

You could also substitute the fruit juice with almond milk, which contains 60 calories per cup, but this will change the flavor of the smoothie.

Since there aren’t any ingredients that you can remove or swap in this drink without compromising the taste, I recommend going for the smallest-sized drink (20 oz) to keep the calories down.

If you want to lower the calories in this drink, ask for it without the Papaya Juice Blend or White Grape Lemon Juice Blend and substitute with either water or plant-based milk.

More Tips For Ordering Low-Calorie Smoothies At Smoothie King 

Here are some additional tips to keep the calories down when you’re ordering a drink at Smoothie King:

• Ask For Non-Fat Milk Or Greek Yogurt 
• Choose A Stay Slim Blend 
• Choose a Kids’ Blend 

1. Ask For Non-Fat Milk Or Greek Yogurt 

Whole milk contains 150 calories per cup. In comparison, non-fat milk and Greek yogurt contain around 86 calories and 80 calories per cup, respectively. 

By making the switch to non-fat milk or Greek yogurt, you could be saving around 65 to 70 calories per cup. 

2. Choose A Stay Slim Blend 

All of the Stay Slim Blends contain less than 350 calories. 

By ordering from this menu, you can rest assured knowing that you aren’t consuming any more than a few hundred calories.

3. Choose a Kids’ Blend 

Many of the Kids’ Blends are relatively low in calories compared to some of the adult blends.

This is mostly because the adult blends come in 20, 32, and 40-ounce cups whereas the kids’ blends come in 12-ounce cups.

For example, the Strawberry Bluegurt Blitz contains just 160 calories and the Choc-A-Laka contains 190 calories. 

However, it’s important to note that a few of the Kids’ Blends contain more calories than some of the adult drinks that are listed in this article.

The CW Jr has 240 calories. While this is still considered lower than our threshold of what’s considered “low calorie”, just know that you can find a few adult blends that are lower than 240 calories.

Make sure to look at the menu before you order to check the relative calorie content of each drink.
