The power of fasting with food. Prolon 5-Day is a patented and scientifically-backed Fasting Mimicking Diet (FMD) that activates cellular clean-up pathways while allowing you to eat.

This program helps you clear out cellular waste, lose weight while protecting your muscle mass, and support your overall health while still nourishing your body.
