Yes, you can drink iced tea while fasting, as long as it is not flavored with something that makes it taste sweet.
Understanding Fasting and Beverages
Fasting protocols often involve abstaining from calorie-containing foods and beverages for a set period. The goal is typically to keep insulin levels low and encourage the body to use stored fat for energy. Consuming drinks that don't trigger an insulin response is key to maintaining a "clean fast."
Why Unsweetened Iced Tea is Acceptable
Based on information regarding clean fasting principles, plain iced tea brewed from black or green tea is generally considered permissible. The critical rule is that it must be unsweetened and free from any flavorings that add sweetness.
According to the provided reference: "Yes as long as it is not flavored with something that makes it taste sweet."
The Effect of Sweetness on Your Fast
Even if a drink contains zero calories or carbohydrates, a sweet taste can potentially interfere with your fast. The reference notes that:
- "Even if a tea has zero calories or carbs, it can trigger an insulin response in some people which isn't great for a fast."
This highlights that even sugar-free sweeteners or artificially flavored beverages might raise insulin levels in certain individuals, potentially disrupting the metabolic state you aim for during a fast. A clean fast seeks to avoid this by sticking to truly non-sweetened options.
Recommended Beverages for a Clean Fast
To ensure you maintain a clean fast, the reference suggests consuming simple, non-sweetened drinks:
- Water
- Black coffee (with no sweeteners)
- Plain black/green tea
Unsweetened iced tea fits within the scope of plain black or green tea served cold, making it a suitable option provided no sweeteners or sweet flavorings are added.

To help you make choices that support your fast, here's a simple breakdown:
- ✅ Drink During Fast:
