You might know that artificial sweeteners like Splenda and aspartame are pro-inflammatory for some people. So, the more sensitive your gut and metabolism, the more likely you are to experience negative side effects when consuming them.
So, are you looking for the answer to the question: Does Splenda Break a Fast?
The short answer is: Yes, Splenda will break your intermittent fast.
But, let’s take a deeper look at how Splenda and the other artificial sweeteners affect your fasting response. If you’re new to intermittent fasting IF or want to learn more about this lifestyle approach, check out our blog post.
What Exactly Is Splenda?
Splenda is a brand of artificial sweetener found worldwide, and it is often used as a sugar substitute in lower-calorie foods instead of table sugar. Sugar substitutes are trendy in foods marketed towards people on a diet and can be found in diet sodas, zero-calorie treats, and sugar-free candy.

Does Splenda Break a Fast?
Splenda is made from Sucralose, Dextrose and Maltodextrin, which is different from other sweeteners in that it’s made from sugar. However, Sucralose has a different chemical structure than sugar, which means that your body isn’t recognizing it as a carbohydrate.
Sucralose is incredibly sweet, up to 600 times sweeter than regular sugar. With Sucralose, Splenda has managed to make a sweetener that is just as sweet as sugar – and calorie-free.
But the real question is: Does Splenda Breaks a Fast?
Does Splenda Break a Fast?
Sucralose itself is non-caloric and won’t have an insulin response, so it won’t break your fast, but the other components in Splenda will raise your blood glucose, which means using Splenda to sweeten your beverages will break your fast.
Which Sweeteners Can You Consume While Fasting?
Are you looking for ways to satisfy your sweet tooth while still adhering to your intermittent fasting diet? It’s possible! With the right sweetener, you can stay fasting without feeling guilty about it.
Here are some of the greatest sweeteners for satisfying your sweet appetite:
1- Stevia: Stevia is a natural, zero-calorie sweetener made from the stevia plant. It has become increasingly popular as it is a healthier alternative to sugar. Though it is not as sweet as sugar, it can still help satisfy that sweet tooth.
2- Monk Fruit: Monk fruit is a zero-calorie, plant-based sweetener that is about 150 times sweeter than sugar. It is the perfect choice for those fasting and looking to stay in ketosis.
3- Coconut Sugar: Coconut sugar is a low-glycemic sweetener made from the sap of the coconut tree. It is considered a healthier alternative to regular sugar and is a great option for those looking to break a fast and still enjoy a sweet treat.
4- Erythritol: Erythritol is a sugar alcohol having a molecular structure comparable to (but yet distinct from!) glucose. Erythritol’s calorie intake is so low that it does not break a fast for weight reduction. However, if you’re attempting to fast for gut rest, you should be cautious since 90% of this sugar alcohol gets absorbed in the stomach.
These are just a few of the sweeteners that those fasting can enjoy. Though, it is important to be mindful of the amount of sweeteners consumed, the right sweetener can make all the difference in making fasting easier and more enjoyable. So, if you’re looking for a way to make your fasts easier, consider one of these sweeteners.
What Can I Eat During a Fast?
You may eat the following things while fasting if you are keeping a clean fast:
1- Water (Unflavored) or Unflavored Sparkling Water
2- Black Tea or Green Tea
3- Black Coffee
Conclusion
You may use artificial sweeteners throughout your window of intermittent fasting since the majority of them contain no calories.
However, it is advised to avoid the majority of popular artificial sweeteners, such as aspartame and Splenda, since they have been shown to have neurotoxic consequences.
Use natural sugar substitutes with no calories instead, such as stevia or monk fruit, which also taste nice but don’t have the negative health impacts that most artificial sweeteners have.
