How many calories are in a Sonic diet cherry limeade?

A Sonic diet cherry limeade is a popular low-calorie beverage option at the famous Sonic drive-in restaurant chain. With its tangy cherry and lime flavors, this drink provides a refreshing, guilt-free treat for health-conscious customers watching their calorie intake. But just how many calories are in a Sonic diet cherry limeade? In this comprehensive guide, we will examine the nutritional facts and ingredients that make up this diet-friendly beverage to determine its calorie count and how it fits into a balanced diet.

Overview of the Sonic Diet Cherry Limeade

The Sonic diet cherry limeade is a variation of their classic cherry limeade, made with low-calorie sweeteners instead of high fructose corn syrup. It combines the tart, sweet taste of cherries with the zesty kick of fresh lime juice. The main ingredients are carbonated water, cherry and lime flavoring, citric acid, and non-nutritive sweeteners like aspartame or sucralose. This gives it the sweet citrus flavor of a regular cherry limeade, without all the extra calories from sugar. The diet version contains 0g fat, 200mg sodium, 43mg potassium, 39g total carbohydrates, 2g protein, and 0g fiber per 20 fl. oz Route 44 size. With its bright red color and refreshing flavor profile, the diet cherry limeade offers the appeal of Sonic’s signature drink with a fraction of the calories.

Determining the Calorie Count

So how many calories are actually in Sonic’s diet cherry limeade? Let’s take a look at the nutritional information to find out.

Sonic provides complete nutrition facts for all of their menu items online. For a 20 fl. oz Route 44 size diet cherry limeade, they list the calorie count as 160 calories.

This calorie amount is for the total 20 oz beverage. However, when dining at Sonic, diet cherry limeades are typically customized and mixed by hand when ordered. So the calorie count can vary slightly depending on the exact ingredients and proportions used.

Some key factors impacting the calories in a diet cherry limeade include:

Size of Drink

Sonic offers diet cherry limeades in different sizes:

Size Calories
Regular (12 fl oz) 100 calories
Large (20 fl oz) 160 calories
Route 44 (40 fl oz) 270 calories

As shown, the calorie count scales up accordingly with larger sized drinks. The nutritional information is based on exact measured ounces, so calorie amounts may vary slightly when mixed by hand. But in general, expect a diet cherry limeade to contain around 100 calories per 12 oz serving.

Sweetener Used

Sonic uses non-nutritive zero calorie sweeteners to give their diet drinks a sweet taste without added sugar. The main sweeteners used in diet cherry limeades include aspartame and sucralose. Both provide the same sweet taste with no calories or carbs, so the type of sweetener does not significantly impact the calorie amount. However, other diet soft drinks sometimes use alternative natural sweeteners like stevia or monk fruit extract. These may contain slight variations in calories, but the differences are negligible.

Ice Content

More ice in a diet cherry limeade will slightly dilute the beverage and lower the calorie density. While ice itself contains no calories, changing the ice-to-beverage ratio can cause small variations in calorie amounts for customized mixed drinks. However, for the standard 20 oz drink size, Sonic factors in average ice content when calculating total calories. So ice differences when mixing individual servings only create minor calorie fluctuations.

Customization and Mix-Ins

Part of the appeal of Sonic drinks is customizing your own unique flavors. Some popular additions to diet cherry limeades include:

  • Flavored syrups (e.g. raspberry, peach, coconut)
  • Fruit purees (e.g. strawberry, mango, pineapple)
  • Whipped cream
  • Maraschino cherries

These mix-in options can add additional calories on top of the base diet limeade. For example, a pump of flavored syrup may contain around 15 calories. A dollop of light whipped cream could add 20-30 calories. While the increases are relatively small, they can quickly add up if multiple mix-ins are added. To keep your diet cherry limeade guilt-free, opt for no or light mix-ins when customizing your drink.

Diet Cherry Limeade Calories in Context

To put the 160 calories in a Sonic diet cherry limeade into perspective, let’s compare it to some other menu options:

Menu Item Calories
Regular Cherry Limeade, 20 oz 310 calories
Classic Burger 420 calories
Chicken Strip Dinner (3 strips) 530 calories
Shakes, regular 20 oz 530-880 calories

As shown, the diet cherry limeade contains far fewer calories than regular sugar-sweetened beverages and indulgent food options. With only 160 calories, it provides a flavorful drink choice that won’t break your daily calorie budget.

To put that in the context of daily nutrition needs:

  • A 2,000 calorie diet would allot about 270 calories for beverages or desserts.
  • A 1,600 calorie diet would allot around 133 calories for indulgent drinks.

So the diet cherry limeade fits comfortably into a balanced eating plan. It satisfies that craving for something sweet and flavorful, while still limiting calories and sugar intake compared to less healthy options.

Nutritional Pros and Cons

Now that we know a Sonic diet cherry limeade contains around 160 calories, how does it stack up in terms of overall nutritional value? Here is a look at some of the key pros and cons:


  • Low calorie for a beverage, allowing it to fit into most diet plans
  • Provides hydration and satisfies thirst with its liquid content
  • Contains no fat, cholesterol, or protein
  • Offers a good source of vitamin C
  • Sweetened with non-nutritive sweeteners instead of sugar
  • Gives a flavorful, sweet treat without excessive calories
  • Customizable to control calories and nutrition


  • High in carbohydrates despite being sugar-free
  • Minimal fiber and nutrient content beyond vitamin C
  • Artificial sweeteners may cause digestive issues for some
  • Higher sodium content than alternative diet drink options
  • Added mix-ins can boost calories and sugar intake

Overall, while not the most nutrient-dense beverage choice, a Sonic diet cherry limeade can be a sensible option for an occasional low-calorie treat. Just be mindful of extra add-ins and enjoy in moderation as part of an overall healthy diet.

Tips for Ordering

Here are some tips to keep in mind when ordering a Sonic diet cherry limeade to lighten up your calorie and sugar intake:

  • Ask for the 20 oz “large” size or smaller to control calories
  • Request light ice if you want more beverage volume per sip
  • Skip high-calorie whipped cream and syrup pumps
  • Ask for sugar-free flavors like raspberry or peach if customizing
  • Substitute a wedge of fresh lime for maraschino cherries
  • Pair with a grilled chicken sandwich or salad to balance the meal

Sticking to size small or medium, avoiding heavy mix-ins, and pairing with lighter food can help keep your Sonic run guilt and calorie-free!

The Bottom Line

So how many calories are in a Sonic diet cherry limeade? According to Sonic’s nutrition information, a standard 20 oz (large) size contains approximately 160 calories. This calorie count is based on the total drink size including ice, rather than just the concentrated beverage. Factors like size, sweetener, and custom add-ins can slightly influence the calories in an individual serving when mixed by hand. But you can generally expect a 12 oz (small) diet cherry limeade to clock in around 100 calories, providing a flavorful low-calorie drink option. Moderating portion size and avoiding heavy add-ins allows this sweet treat to fit into a balanced, calorie-conscious diet.
