ProLon® Benefits

Convenient

ProLon meals come in 5 grab-and-go boxes (one for each day) that include plant-based energy bars, soups, a variety of snacks, drinks, and supplements.

Weight Loss

ProLon has been tested to help people lose an average of 5.7 lbs. and 1.6 inches of waist circumference, while preserving lean body mass.*

*Benefits seen in a clinical study of the 5-day ProLon cycle once a month for three consecutive months. 

Plant-Based

ProLon is gluten-free and uses healthy, mostly plant-based ingredients including olives, vegetables, fruit, nuts, seeds, and herbal teas.

Rejuvenate

ProLon supports your body’s natural process of cellular clean-up which naturally gets triggered when your body is in a prolonged (3 or more days) fasting state.

Great Taste

ProLon was created in collaboration with some of the world’s best food scientists and chefs to provide delicious food that incorporates the science of FMDs.

Nourishing

ProLon provides the body with a scientifically developed combination of micro and macro-nutrients designed to keep the body nourished while in a fasting state.

The best fasting product out there.
...I felt renewed and ready to continue my journey to a healthier me.

This was my first 5 day.
I was amazed about how I was rarely hungry and how much energy I had.*
*Most ProLon users report increased energy after completion of their fast.
Round 2 please.
What a wonderful plan and support team. I was nervous and a little skeptical but am so glad I made the decision to try this. I can't wait to start my second one please.

Trigger Autophagy — Cellular Clean Up

ProLon Fasting Mimicking Diet triggers “autophagy,” your body’s natural way of cleaning house. Your cells clean and recycle old and damaged parts, resulting in a profound benefit — cellular rejuvenation.

Day 1

Transforming to
a Fasting State

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

Day2

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.

Day3

Autophagy
Clean Up State

Cellular clean-up (autophagy) begins. Fat-burning and ketone production/ utilization continues and increases.

Day 4

Cellular
Rejuvenation

Cellular cleaning/renewal & fat-burning continues. You're in the final stretch!

Day 5 and Beyond

Renewal & Change

Fast completed, cellular renewal continues beyond Day 5.
