There’s a
Better Way to Fast

If you’re skipping breakfast during intermittent fasting, your body is missing out on essential nutrients during key daylight hours. Not only does the body use nutrients more efficiently earlier in the day, but many studies show that eating breakfast is crucial for cardiovascular and overall health.Prolon’s patented Fasting Bars are clinically shown to provide essential nutrients during critical daylight hours, when your body needs them most, without breaking your fast.

How do Fasting Bars work?

When we eat, our bodies use specific food radars, or Nutrient Sensing Pathways (NSPs) to help make decisions about what to do with the nutrients we consume. These pathways send signals to various parts of the body, instructing them to use energy, regulate metabolism, repair and grow cells, and so much more.

During fasting, however, the body downregulates the stimulation of NSPs, to minimize any growth activity and conserve energy. 

But Fasting Bars are crafted with a precise blend of macro and micronutrients designed to keep your body in a fasting state and your ketones elevated by staying below NSPs. This offers even more benefits than a water-only fast, because you aren’t starving your body and potentially increasing your risk for elevated stress, which has the potential to lead to other health issues.

Add Fasting Bars to your intermittent fasting routine as a…
