Does Chewing Gum Break A Fast?

Yes, chewing gum will break a fast. According to Dr. Jason Fung, “Sweeteners can certainly produce an insulin response, but generally, for gum, the effect is so small that there is likely no problem from it. So yes, technically it does break the fast, but no, it usually doesn’t matter.”

However, the one issue with chewing gum while fasting, Dr. Fung added, is that “gum is usually not recommended because the act of chewing and the sweetness usually triggers salivation and hunger.” So for some, even if you chew sugarless gum, it might actually make fasting more challenging.

So yes, chewing gum breaks your fast. You should avoid chewing gum while fasting.

Intermittent fasting expert Gin Stephens also agrees that chewing gum should be avoided while fasting. She advises to chew gum during your eating window if you desire to have gum.
