Yes, But Only if It's Unsweetened
Can you drink iced tea on a keto diet? Yes, you can, but the critical distinction lies between unsweetened and sweetened varieties. Unsweetened iced tea, whether made from black, green, or herbal leaves, is naturally a zero-carb, calorie-free beverage and perfectly compliant with a ketogenic lifestyle. The issue arises with store-bought options and restaurant-style sweet teas, which are often loaded with sugar, high-fructose corn syrup, and other non-keto sweeteners. A single 16-ounce serving of commercial iced tea can contain over 20 grams of sugar, which is enough to knock many people out of ketosis.
The Problem with Conventional Iced Tea
The carbohydrates in a traditional iced tea come primarily from added sugars. For someone aiming for 20-50 grams of net carbs per day, a single sweetened tea can consume a significant portion of their daily limit. Even more problematic are those teas sweetened with fruit juice or honey, which are also high in natural sugars and carbohydrates. While these options might sound healthier, they are just as likely to sabotage your keto efforts as table sugar.
Your Guide to Keto-Approved Iced Teas
To ensure your iced tea is keto-compliant, you have two primary options: make it yourself or choose specific sugar-free, store-bought alternatives. Making your own allows for complete control over the ingredients, while careful label-reading is essential for purchased products. For those who enjoy a bit of sweetness, several keto-approved sweeteners can mimic the flavor of sugar without the carbs.
Types of Keto-Friendly Teas
- Black Tea: Robust and bold, black tea serves as a classic base for iced tea and is virtually carb-free.
- Green Tea: Known for its antioxidants, green tea provides a lighter, more floral flavor and is excellent for keto.
- Herbal Tea: Varieties like chamomile, peppermint, hibiscus, and rooibos are naturally caffeine-free and low-carb.
- Matcha: A finely ground green tea powder, matcha offers concentrated benefits and can be used to make a creamy, zero-carb iced matcha latte.
How to Make Your Own Keto Iced Tea
Creating your own delicious, low-carb iced tea is simple and only requires a few ingredients:
- Steep Your Tea: Brew your favorite unsweetened black, green, or herbal tea bags in hot water. Adjust the steeping time based on your desired strength.
- Add Sweetener: Stir in your preferred keto-friendly sweetener while the tea is still warm to ensure it dissolves completely. Some popular options include stevia, erythritol, or monk fruit.
- Chill and Serve: Let the tea cool to room temperature, then refrigerate for at least an hour. Pour over ice and add a squeeze of lemon or lime for extra flavor.

Finding Sugar-Free Iced Tea in Stores
If you prefer the convenience of store-bought iced tea, it's crucial to read the nutritional labels carefully. Look for brands that explicitly state "unsweetened" or "sugar-free". Some companies are now marketing keto-specific or low-carb teas that use approved sweeteners. Always check the ingredients list to confirm no hidden sugars or high-carb fruit juices are present. Popular brands like Southern Breeze offer zero-carb sweet teas, while others like Zest Tea have ready-to-drink options.
Additions to Boost Flavor (and Health)
To enhance your keto iced tea without adding carbs, consider incorporating these natural and healthy ingredients:
- Fresh Citrus: A squeeze of lemon or lime adds a bright, refreshing taste with minimal carbs.
- Mint Leaves: Fresh mint offers a cool, invigorating aroma and flavor.
- Ginger Slices: Adds a spicy kick and potential digestive benefits.
- Cinnamon Sticks: Infuses a warm, subtle spice flavor.
- MCT Oil or Heavy Cream: For those following a higher-fat keto plan, adding a tablespoon of MCT oil or a splash of heavy cream creates a rich, creamy beverage.
The Bottom Line
While a glass of sweet iced tea from a restaurant or a bottle from the convenience store is not keto-friendly, unsweetened iced tea is a versatile and refreshing beverage that fits perfectly into a ketogenic diet. By brewing it at home and using approved sweeteners, or by carefully selecting sugar-free commercial options, you can enjoy a delicious, cooling drink without the carb crash. The key to staying in ketosis is diligent label-reading and a preference for making your own sugar-free concoctions.
Conclusion
In summary, the answer to "Can you drink iced tea on a keto diet?" is a resounding yes, provided you avoid the sugar and high-carb additions found in most commercial versions. Homemade iced tea, sweetened with keto-approved alternatives like stevia or erythritol, is a zero-carb staple that can be customized with various herbs and citrus flavors. For store-bought options, always check the label for hidden sugars and opt for unsweetened varieties to maintain ketosis. This simple modification allows you to continue enjoying this classic refreshing drink while adhering to your low-carb, high-fat lifestyle.
