Does LaCroix Break A Fast?

LaCroix is a flavored sparkling water beverage that is a welcome alternative to plain water when fasting. It is calorie-free and made of all natural sweeteners, but does that mean that it won’t cause your fast to break?

Straight to the point – no, it will not cause your fast to break. Let’s investigate why this is so.

Are There Calories In LaCroix?

LaCroix flavored sparkling water is calorie-free according to its label and nutritional databases.

LaCroix nutritional info

This makes it ideal for consumption while fasting as you will not be taking in any calories that could potentially cause it to break. Keep in mind that the consumption of calories defeats the purpose of a fast, regardless of your reason for the fast. 

Calories necessitate the digestion of the food from which they were obtained and impair the beneficial metabolic processes obtained from fasting.

Will La Croix Raise Blood Glucose Or Insulin Levels?

No, LaCroix will not adversely affect your blood glucose or insulin levels, as it is devoid of calories and sugar. This makes it very attractive to diabetics or when on a ketogenic type fast as it will allow for the production of ketone bodies.

Will LaCroix Affect Autophagy?

Drinking LaCroix will not affect autophagy, since no nutritional value is gained from its consumption. However, what might happen is increased hunger from the use of natural flavors and sweeteners.

This is quite the ironic development since you might actually feel hungry on the fast and this by itself could cause you to break yours.

Can I Use LaCroix on Fasting Days?

Yes, LaCroix can be consumed while fasting without breaking the fast. This is due to the fact that it contains no calories or sugar. However, you should be aware that regardless of the type of sweetener/flavor included (whether that be natural or artificial) there is the risk of an increase in hunger and cravings since the hormone ghrelin can be stimulated.

Ghrelin is known as the hunger hormone and can result in strong cravings while you are fasting, Therefore, it is best to consume LaCroix in moderation.

Also, consuming the beverage outside of your fasting window is absolutely fine as well.

Final Words

In short, LaCroix is a calorie-free and sugar-free sparkling water beverage that will not break your fast. However, the natural flavors and sweeteners in LaCroix might increase feelings of hunger. Therefore, it is best to consume in moderation.

It doesn’t matter whether you drink it during your fasting window or not, as long as you don’t go overboard with it. And finally, if you’re feeling particularly hungry while fasting, then LaCroix might not be the best beverage of choice.

Other than that, feel free to enjoy this sparkling water guilt-free!
