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.

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.
