Unwrapped Fast Bar with Ingredients

Fasting has been a fascinating human practice across millennia. Its humble beginnings date back to early times when humans foraged and were forced to fast while finding food sources. Eventually, fasting took shape as a spiritual practice for forgiveness, soul or body cleanse, or even sacrifice and meditation. Medically speaking, fasting has been used to help relieve symptoms of specific conditions based on scientific breakthroughs of fasting in cell metabolism. At present, fasting rises as a powerful health and wellness trend to help our bodies stay healthy and enhance cellular function.

L-Nutra, our founding company behind Fast Bar, commercializes the Fasting Mimicking technology using the potential cellular renewal power of fasting and researched for over 25 years at the University of Southern California (USC). Exciting and promising scientific discoveries about fasting led L-Nutra to introduce the very first 5-day Fasting Mimicking Diet® (FMD®) under the brand ProLon® in 2016.

Today, L-Nutra is proud to announce the launch of Fast Bar™, the first nutrition bar in the world specifically formulated to allow you to fast while you eat. Fast Bar has been pre-clinically and clinically tested as part of the Fasting Mimicking Diet (FMD)®.

At L-Nutra we are pioneers helping to build a healthier world by bringing to market the Fasting Mimicking technology and products, which may help individuals prevent or delay the onset of chronic diseases.

We invite you to discover Fast Bar and L-Nutra to learn more about fasting as an easy, tasty, and convenient way to improve your health.
