Fasting Mimicking Diet
What is the Fasting Mimicking Diet?
The first and only patented nutrition program to support healthy aging through cellular rejuvenation.
The Fasting Mimicking Diet (FMD)
Fasting benefits — without the water-only fast
A revolutionary five-day nutrition program scientifically formulated to mimic the effects of a prolonged water fast while still allowing nourishment — supporting the benefits of fasting without the challenges and risks that come from water-only fasts.

Autophagy ends with a full reprogramming of new cells. When you reprogram, you are impacting the DNA. We are reprogramming the cells to behave younger.

How does FMD work?
Five days that build on one another
Each day of the Prolon fast is carefully formulated to activate your body's natural cell-rejuvenating processes. The five days build upon one another to trigger the various stages of fasting that contribute to cellular renewal.
Typically by day 2 the body enters ketosis, burning fat for fuel, and by day 3, autophagy kicks in — your body's natural process of recycling or removing damaged cells. It continues throughout the rest of your fast, and the FMD's effects may go beyond autophagy to support complete cellular reprogramming.

The science behind your FMD
Two phases of cellular renewal
Autophagy
Autophagy, the first phase of rejuvenation, begins around day 3 of the FMD. During this process, the body clears out damaged cellular components, recycling essential materials and preparing for renewal.
Cellular reprogramming
Following autophagy, new, healthier cells emerge, reprogrammed to function more efficiently. This cellular reset impacts DNA, promoting a youthful cellular profile that can support healthy aging and a healthy immune system.
One program. Many benefits.

The creator of Fasting Mimicking Technology
Dr. Valter Longo, Ph.D
Dr. Valter Longo, Director of the Longevity Institute at the University of Southern California, was recognized by TIME as one of the top 50 most influential people in health. As the pioneering mind behind the Fasting Mimicking Diet, Dr. Longo was awarded the first-ever patent for Healthspan.
His groundbreaking work revealed how cells sense nutrients, leading him to develop the FMD formulation. Through extensive mouse and human trials, he demonstrated the powerful benefits of this approach — the foundation of the Prolon product line.
