Our 5-day nutrition program is the only program patented for promoting rejuvenation 
from within for healthy aging.

Discovered and developed at the Longevity Institute of the University of Southern California, our technology is plant-based nutrition that allows the body to enter into a beneficial fasting state without triggering the cells’ nutrient sensors. As the name suggests, it actually mimics fasting…while still allowing you to eat food. This nourished fasting fine-tunes cells, supports healthy aging, and eliminates the need to do a water-only starvation fast, which can have negative side effects. Take your body on a 5-day journey towards renewal.

DAY 1

Transforming to a Fasting State

The body transitions into a fasting state 
& fat-burning mode so it can begin 
cellular clean-up.
DAY 2

Fat burning & Ketogenesis

Fat-burning ramps up, contributing to the initiation 
of ketogenesis (ketone production). By the end of 
this day (48hrs), ketosis may occur.
DAY 3

Autophagy / Clean-up State

Cellular cleanup (autophagy) begins. 
Fat-burning and ketone production/utilization 
continues and increases.
DAY 4

Cellular Rejuvenation

Cellular cleaning/renewal & fat-burning continues. Your cells begin looking like younger versions of themselves. You're in the final stretch.
DAY 5

Renewal & Change

Fast completed, cellular renewal continues beyond day 5. Sustained cellular recycling, rejuvenation, 
and renewal. Sustained ketosis may occur.

Macro & micro precision nutrition keep you in a fasting state.

Trigger Autophagy - the magic of celluar rejuvenation.

What Experts have to Say

ProLon carries so many weight, metabolic and cellular benefits that not only do I recommend it, but I decided to join the company’s mission full time as Chief Medical Officer

Dr. William Hsu, M.D

I love the science supporting ProLon, and I love that the science has been published in multiple peer reviewed journals. It allows me to suggest ProLon with confidence. I have used fasting and time restricted eating in my practice for years; ProLon augments this and takes it to the next level.

Dr. Amy Savagian, MD

Not only do I recommend ProLon as a frequent nutritional intervention, I’ve done it myself numerous times. I love this product so much, I invested in the company
