Craving something a little sweet?


If so, you may be looking to add monk fruit sweetener as a zero calorie option to your Intermittent Fasting routine. But does Monk Fruit Sweetener break a fast?


Recently, I've been getting a ton of questions on monk fruit as a form of sweetener and whether or not you can use it daily with Intermittent Fasting.


Today, I'm breaking down what you need to know about monk fruit sweetener and whether monk fruit sweetener breaks a fast!


What Is Monk Fruit?

Monk fruit sweetener is derived from the monk fruit plant. Traditionally, monk fruit has been used and grown in China. It has been found to be about 250-400x sweeter than regular cane sugar, but without the carbohydrates that will lead to increases in blood glucose levels. Instead, the sweetness comes from an antioxidant called mogrosides that is naturally in monk fruit.


Does Monk Fruit Break a Fast?

Monk fruit does not break a fast if you don't have an insulin response to it. There has been some research that monk fruit (and other non-nutritive sweeteners, such as stevia) can cause an insulin response in some individuals while in others it doesn't. Because this varies from person-to-person, it's important to test it out on yourself and see how your body responds. I personally prefer to err on the side of safety and not include monk fruit in my drinks while fasting to ensure it does not break a fast.

It provides the sweet flavor without the additional calories or carbohydrates that other sweeteners have.


Should You Use Monk Fruit?

This is a tricky one for me to answer. If you DO choose to use monk fruit sweetener, it's important to make sure that it only contains monk fruit. Some monk fruit sweeteners contain carbohydrate-containing sugars that will increase your blood glucose levels. There are also monk fruit sweeteners that add in sugar-alcohols, which technically don't increase your blood glucose levels but studies have found these sugar alcohols are tied to GI distress.


Ultimately, I want you to ask yourself - why am I craving something sweet? Although monk fruit sweetener doesn't raise blood glucose levels and therefore is technically fine to have (in small amounts) with Intermittent Fasting, it can be detrimental to your goals to use it throughout the day for two reasons:
