“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?

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, so each day has its own unique and important role in that process. Typically by day 2 the body enters ketosis, burning fat for fuel, and by day 3, autophagy kicks in. As your body's natural process of recycling or removing damaged cells, autophagy is like a deep, internal spring cleaning - and will continue working throughout the rest of your fast (even going until two days after it’s completed).. However, the FMD’s effects may go beyond autophagy to support complete cellular reprogramming.

The science behind your FMD

Phase 1: 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.

Phase 2: 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.

Fat-focused weight loss

Unlike many weight loss products and drugs, Prolon allows you to lose visceral fat while protecting muscle.

Improved skin health & radiance

Three consecutive cycles of Prolon 5-Day can lead to increased skin hydration and a more radiant complexion.

Mental clarity & focus

With cells refreshed after completing the 5-day cycle, many users report improved energy levels and vitality after the fast. 

Healthy aging through cellular rejuvenation

The Prolon FMD is the only nutrition program proven, in landmark research, to trigger autophagy in humans. This cellular renewal process is a game-changer for health and longevity. Research shows that three consecutive monthly cycles of the Fasting Mimicking Program can reduce your biological age.

Renewed energy

20 days of Prolon is as effective as 120 days of the Mediterranean diet on heart health, and supports healthy metabolic markers.

Metabolic reset

Three consecutive cycles of Prolon 5-Day can lead to increased skin hydration and a more radiant complexion.
