Does Monk Fruit Break a Fast? [Intermittent Fasting Tips]

Updated: Jan 19, 2022

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.

Why Do People Use Monk Fruit?

With the increased awareness of sugars detrimental effect on health, many people are looking for alternatives that won't raise blood glucose levels. Monk fruit has been found to have zero effect on glycemic load and blood glucose levels. This is also why you'll find monk fruit used in many protein powders. 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:

1. You're masking the reason that you're CRAVING sugar.

Stop and ponder that question - Why are you craving sugar? What is your body telling you? If you aren't sure how to answer this, I dive into the science behind this question with the video below.

2. You may induce further sugar cravings.

Because you're masking the reason why you're craving sugar in the first place, this will inspire further cravings for sugar in your body. And those cravings will most likely lead to snacks/meals that will not help you feel good or achieve your wellness goals.

Simply put, the more often you include added sugars of any type, the more your body will crave those sugars. Having a small amount of monk fruit in your Chocolate Bomb Bites from the Level Up Guide or occasionally adding it to your Keto Coffee won't hurt your goals. But it's important to still use this sweetener occasionally rather than in everything you consume. This will help to keep any further sugar cravings down and allow you to feel your BEST.

You say that monk fruit causes an insulin response in some, but not in others and "because this varies from person-to-person, it's important to test it out on yourself and see how your body responds". How will I know if my body's had an insulin response after having monk fruit?

Replying to

Hi! One "round about" way to test this is by testing ketones after having just monk fruit in the "fasted" state. If ketone production dips, then likely the body produced insulin as a response to monk fruit. If not, then it likely did not. This isn't 100% accurate, but it can be a way to monitor this on your own.
