Smoothie King’s GLP-1 Menu: Are these smoothies a healthier choice?

Smoothie King has long positioned itself as a healthier alternative to traditional fast food, building its brand around customizable blends, functional ingredients, and goal-driven menus. Over the years, it’s even evolved alongside changing nutrition trends—moving from overly sweet smoothies toward options that emphasize protein, fiber, and fewer added sugars.

Now, the landscape has shifted again. As more people use GLP-1 medications for weight loss and metabolic health, expectations around food have changed, too. Many people are eating smaller portions, prioritizing protein, and looking for options that feel satisfying without being heavy or overly sweet.

In response, restaurants and chains are starting to rethink what “better-for-you” actually means. Coffee and smoothie brands have rolled out more protein-forward options—like Starbucks’ new protein drinks and Dunkin’s protein milk beverages—designed to deliver more nutrition per sip. Smoothie King’s GLP-1 Menu fits into that same trend, aiming to offer convenient, protein-focused choices that better align with how people on GLP-1s are actually eating.

In fact, Smoothie King was one of the first chains to create a menu designed specifically for people taking GLP-1s. Instead of blends with lots of added sugar, these smoothies focus on high-protein, fiber-rich ingredients and low to no added sugar.

Do Smoothie King’s GLP-1 smoothies actually support a balanced lifestyle for someone taking these medications? We reviewed the nutrition facts and asked Dr. Karen Mann, MD, Noom’s Medical Director, for her insights.

What is Smoothie King’s GLP-1 Support Menu?

Smoothie King’s GLP-1 Support Menu includes five smoothies that were created to support some of the most common challenges people experience on GLP-1 medications. People taking it for weight loss have lower appetites, and also contend with side effects like nausea, vomiting, diarrhea, and constipation. This can lead to people having trouble meeting their protein or fiber needs. While a calorie deficit is needed for weight loss, cutting calories and protein too much can lead to muscle loss and fatigue.

To help people get the nutrients they need while on these medications, each smoothie is designed to be:

• High in protein to support muscle maintenance and fullness
• Fiber-rich, to aid digestion and satiety
• Free of added sugars, which many people on GLP-1s find harder to tolerate (some include stevia)
• Moderate in calories, making them easier to drink when appetite is low

Smoothie King developed the menu in collaboration with a registered dietitian, with the goal of helping people meet nutritional needs even when eating less overall.

While the menu was designed with GLP-1 users in mind, these smoothies can also work for people who aren’t taking GLP-1 medications but are looking for healthier options.

Smoothie King’s GLP-1 Support Menu: What’s on the menu?

Each smoothie on Smoothie King’s GLP-1 Support Menu follows the same nutrition-forward framework—prioritizing protein, fiber, and manageable portions—while offering different flavors and use cases.

• Gladiator® GLP-1: A high-protein base available in chocolate, vanilla, or strawberry, with the option to add two ingredients like almonds, almond butter, berries, Ginger, carrots, or greens.
• Slim-N-Trim™ GLP-1 Mango Greens: A lower-calorie, fruit-forward blend made with mango, Greek yogurt, almond milk, kale, ginger, spinach, and protein powder.
• Keto Champ™ GLP-1 (berry or chocolate): A lower-carb option featuring almond milk, almond butter, berries—or cocoa and stevia in the chocolate version—plus a keto-friendly protein powder blend.
• The Activator® Recovery GLP-1 Almond Berry: A blend of berries, almond milk, coconut water, and protein powder, designed with hydration and digestibility in mind.
• Power Meal Slim™ GLP-1 (chocolate, vanilla, or strawberry): A lower-calorie, meal-replacement-style smoothie made with protein powder, fruit, and almond milk, with a smoother texture that may be easier to tolerate.

Smoothie King’s GLP-1 Support Menu: Nutrition facts and calories

Each of the GLP-1 smoothies provides protein—often 20 grams or more in a 20-ounce smoothie—with varying amounts of fiber, depending on the blend and add-ins. Calorie ranges stay relatively moderate for most options, making these smoothies easier to fit into a routine when appetite is lower. Here’s a look:

Smoothie (20-ounce size)	Protein (g)	Fiber (g)	Calories
Gladiator GLP-1	45–61 g	2–14 g	220–560 (depending on add-ins)
Slim-N-Trim Mango Greens	22 g	5 g	200
Keto Champ GLP-1	24 g	14–15 g	420–450
Activator Recovery Almond Berry	24 g	5 g	200
Power Meal Slim GLP-1	19–22 g	6–10 g	190–210

Are Smoothie King’s GLP-1 menu items good for people taking GLP-1s?

They can be. Smoothie King’s GLP-1 smoothies emphasize protein and fiber while keeping added sugar low. That focus is especially important for people using GLP-1 medications.

“When someone is on a GLP-1, appetite often drops significantly, which means it can become harder to get enough protein, fiber, and nutrients without being very intentional,” says Dr. Mann.

This is important because:

• Protein helps preserve muscle mass and support metabolism during weight loss.
• Fiber is important, too. General guidelines recommend about 25 to 38 grams per day. But most people fall short, even before GLP-1 medications, which can slow digestion and are often connected with constipation.

“Protein helps protect muscle, and fiber supports the gut microbiome, fullness, digestion, and blood-sugar stability,” Dr. Mann explains.

Is Smoothie King’s GLP-1 menu healthy?

Whether Smoothie King’s GLP-1 menu is “healthy” depends on how—and how often—you get items from it. These smoothies are designed to be easy to drink and lower in calories. This can make them appealing to people taking GLP-1 medications who may feel full quickly or struggle with appetite. They are still drinks, not solid meals, and their nutritional value varies based on ingredients, portion size, and customization.

For those taking GLP-1 medications, Smoothie King’s GLP-1 smoothies might be a supportive option, particularly on days when appetite is low or eating a full meal feels overwhelming. While Smoothie King positions these blends as “meal-replacement smoothies,” they’re best viewed as occasional drinks rather than everyday replacements for meals.

“Whole foods are generally the best foundation for meals whenever possible,” Dr. Mann says. “But if you’re short on time, feeling nauseated, or struggling to eat, a smoothie that includes multiple macronutrients—like protein, fiber, and carbohydrates—can serve as a temporary substitute.”

Ingredient choices and customization matter:

What you add to a smoothie can significantly change its calorie content, fiber, fat, and how filling it is. Small customization choices can make the difference between a drink that leaves you hungry and one that actually supports energy and satiety.

• Choose fiber-boosting add-ins when possible. Ingredients like fresh or frozen berries and leafy greens add fiber and nutrients, which can help slow digestion and support gut health.
• Use healthy fats strategically. Add-ins like almond butter or whole almonds increase calories, but they also provide essential nutrients and can help you feel fuller longer. “Healthy fats play an important role in a balanced diet,” Dr. Mann notes. “Even though they’re more calorie-dense, including them can help support satiety—particularly when appetite is reduced.”
• Be mindful of sweeteners. Some smoothies use alternatives like stevia. While generally safe, these sweeteners can cause bloating or digestive discomfort for some people, so paying attention to how your body responds matters.
• Understand your protein options. Protein powders are a convenient way to increase protein when you’re short on time or not eating much. While whole-food protein sources often offer additional nutrients like fiber and healthy fats, protein powder itself isn’t inherently unhealthy—it’s simply a tool that can help you meet your needs on the go.

“No one ingredient is inherently bad,” Dr. Mann notes. “What matters is how they make you feel and whether you’re meeting your needs across the day.”

Is Smoothie King the only chain with a GLP-1 menu?

Smoothie King may have been one of the first large national chains to introduce a menu specifically labeled for GLP-1 users, but it’s far from the only restaurant responding to changing eating patterns.

Other examples:

• Shake Shack launched a Good Fit Menu highlighting higher-protein, simpler builds.
• Chipotle now offers a High Protein Menu focused on customizable, protein-forward bowls.
• Starbucks debuted a high-protein line of drinks for customers looking for protein-enriched lattes and protein cold foams. 
• Dunkin’ introduced protein milk to boost the nutrition of its drinks.

Together, these shifts show how protein—and GLP-1s—are reshaping menus to have options with a higher nutritional impact.

FAQ about Smoothie King’s GLP-1 smoothies

What are GLP-1 smoothies at Smoothie King?

Smoothie King’s GLP-1 smoothies are a set of five blended drinks created to support the nutritional needs of people taking GLP-1 medications. They prioritize higher protein and fiber, zero added sugar, and moderate calories, with ingredients and portion sizes designed to be smaller. 

Can I have a smoothie while taking a GLP-1?

You can have a smoothie while taking GLP-1 medications, but the nutritional quality is important. Smoothies that are balanced with whole foods like fresh or frozen fruits and vegetables and low-fat Greek yogurt can be a good way to keep your energy up, especially on days when your appetite is lower. What matters most is the overall nutrient quality and how that smoothie fits into your daily eating pattern.

What is the best smoothie at Smoothie King for weight loss?

There isn’t a one-size-fits-all “best” smoothie for weight loss, because what supports weight goals depends on your calorie needs, appetite, and overall eating pattern. Options that emphasise whole foods, higher protein, adequate fiber, and lower total calories (like the Slim-N-Trim™ GLP-1 Mango Greens or the Power Meal Slim™ GLP-1) may fit well into a balanced plan. For people needing more satiety or muscle support, the Gladiator® GLP-1 stands out because of its higher protein content. The best choice is the one that satisfies your hunger, fits your energy needs, and helps you maintain a sustainable, balanced routine.

The bottom line: Smoothie King’s GLP-1 smoothies can be healthy options

Smoothie King’s GLP-1 Support Menu reflects a larger change in how people want to eat: generally higher protein, more fiber, and to fill in nutritional gaps. And, any of these smoothies can fit into a balanced routine when they’re used as occasional options rather than default meals. They can be especially helpful for people navigating appetite changes due to GLP-1 medications.

Sustainable weight loss is about making small changes to your diet and lifestyle habits that fit into your life, not extreme overhauls.
