Fasting With Food™
The formulation of Fast Bar comes from science. After more than 20 years of research, scientists at the University of Southern California (USC) discovered a nutri-technology that nourishes the body while keeping it in a fasting mode known as the Fasting Mimicking Diet (FMD®).

L-Nutra took the delicious nut bar from the FMD and made it available as Fast Bar. It can help with intermittent fasting, allowing you to fast for 12 hours and then eat a Fast Bar to curb hunger until your next meal*. Or, it can be consumed on-the-go when you are short on time to eat.

*Benefits seen in a randomized, controlled study in 105 adults after a 15-hour overnight fast comparing the glucose and ketone results every hour for 4 hours in the Fast Bar group, breakfast group and water-fast group. Data on file.

The Same Glucose & Ketone levels as drinking water
Fast Bar’s proprietary formula of premium ingredients doesn’t trigger your body’s nutrient sensing system, so your body’s tricked into thinking it’s fasting. It's the only thing you can eat during your fasting window without breaking your fast — eat without your body even knowing
