Does Splenda Break A Fast?

Yes, Splenda breaks a fast. You should not consume Splenda while fasting.

Does Splenda Break A Fast – Further Details

Yes, Splenda breaks a fast. Many fasting experts have differing opinions on using a small amount of Splenda while fasting.

I believe in the power of clean fasting. Additionally, any food or beverages besides water, tea or black coffee stimulates digestive processes, the gut and may spike insulin levels. All of these processes pull you out of a fasted state.

Splenda is made from sucralose. Sucralose on its own does not have calories, however to make Splenda, dextrose and malodextrin are added to sucralose. Did you know that malodextrin has a higher glycemic index than table sugar? This means that maltodextrin can cause a spike in blood sugar shortly after eating foods that contain it. (1)

While blood sugar spikes are normal when eating, this means that your insulin levels will spike and Splenda WILL break your fast.

What Can I Consume While Fasting?

If you are following a clean fast, you can consume the following items when fasting:

  • Water (unflavored, no added fruit)
  • Black coffee
  • Plain green tea or black tea
