Diet Limeades
Sonic’s Diet Limeades is my last healthy drink option. It’s made from freshly squeezed lime juice, and Sprite Zero, and is delicious. It has only 5 to 15 calories, depending on how large you choose. This makes it a great low-calorie option. If you’re looking for a refreshing, flavorful, and low-calorie drink with just 5 calories, ask for the small size.
These drinks are low in calories, sugars, and carbs and can provide some sodium for your body. Sonic offers a low-carb diet of cherry limeade. It isn’t sugar-free but it has a lot less sugar than the regular version.
A Diet Cherry Limeade is the best keto drink at Sonic. It is refreshing and delicious, with just 4 g net carbs. One serving of Diet Limeade Large contains 4g total carbohydrates, 4g gross carbs, and 20 calories. A former employee who loves everything Sonic said a Diet Cherry Limeade has sugar unless you specify.
They are available in lemon, cherry, or lime flavors.
Bottled or tap water
You can cut down on calories by getting bottled or tap water if you plan to eat a burger or a dog.
This is not an easy task with all the additional items on your list. However, it can make a big difference in your calorie intake, sugar intake, and carb intake.
You will also be a blessing to your waistline and body.
Unsweet Iced Tea

Sonic offers a refreshing alternative to limeades, slushies, and unsweet iced teas.
You can be sure you made the right choice by choosing water that is more flavorful than water and has the same amount of calories and sugar (0).
The RT 44 has only 35 mg of sodium and 0 calories.
Coffee

There are many healthy compounds in coffee that help prevent a range of diseases, including polyphenols, which may help to prevent type 2 diabetes, heart disease, and cancer. Drinking one cup of coffee can pack in 200-550mg of these helpful micronutrients. Most of the antioxidants in coffee fall into two categories:
- Hydrocinnamic acids: These micronutrients energize the body and prevent oxidative stress.
- Polyphenols: These plant compounds help to lower blood pressure, improve cholesterol levels, and may have anti-aging properties.
Do you know what’s great? Black coffee. If you’re on the hunt for a sugar-free drink, black coffee will do the trick 99% of the time. And, if it’s during the middle of summer, it might be refreshing to ask for your black coffee over ice.
Their “Green Mountain Coffee Roasters” is one of the most healthful options on their menu. It will give you a boost and provide you with energy for the day ahead.
Your body will get antioxidants from the coffee and zero sugar. Don’t add sugar or creamers to make it worse.
Their cold brew coffee has only 12 grams of sugar, and their French Vanilla cold-brew iced coffee has only 17 grams and 210 calories.
Milk
A 1% milk is a great option if you are looking for something more than water.
You can get your body vitamin D and protein from milk. It is also low in calories and sugars, which makes it a healthier choice than other drinks.
You might need to order the kids’ menu if you really want milk.
