Why ProLon fasting bar?

Fast on your own terms. You can eat a Fasting Bar and extend your fasting window! Who wouldn’t want to actually eat something as opposed to just drinking water?

Intermittent Fasting Bar was scientifically formulated with these ingredients so that it doesn’t trigger the food sensing system, unlike your usual meals. We call this the fasting mimicking effect and it means that when you eat it during your fasting window, it curbs your hunger without breaking your fast, so you can fast for longer*!

How to enjoy a Fast Bar® and experience the health benefits that come with it

Why and when to use a Fasting Bar

  • Fasting Bar is ideal for those who skip breakfast, practice intermittent fasting, or follow a paleo, keto or fasting diet;
  • Give your body heart-healthy nuts;
  • Enjoy one as a snack anytime during the day to fuel your body when on the go;
  • Fasting bars can be purchased in boxes of 10.

Fasting Bar’s recipe is designed to nourish your body while maintaining its fasting state. For that reason, it’s best enjoyed during either your morning intermittent fasting window or as a late-night snack to satiate you before bed.

Similar to water, our delicious flavours do not raise your blood glucose levels and keep your ketones in a fasting state!
