What is Fasting Mimicking?

Enter the concept of fasting mimicking—an approach that tricks the body into thinking it is fasting while allowing for food.

ProLon Fasting Mimicking Diet is a 5-day meal program that provides scientifically researched micro- and macro-nutrients in precise quantities and combinations that nourish the body, but are not recognized as food, and therefore mimics a fasting state.

Until recently, the idea of fasting with food was incomprehensible. After all, the definition of fasting is to abstain from food for a specific period of time. And it’s during this period that the body experiences various fasting modes, each offering a range of life-enhancing, physical effects. The benefits of these effects can increase with longer fasts. The challenge for many, however is to get through a prolonged fasting period (between 4-7 days) without food.

Here's How it Works

Here’s what physical effects take place during the 5 days on the Fasting Mimicking Diet combined with the food and drinks you will consume on that day.

Day 1

Transforming to
a Fasting State

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


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.


Clean Up State

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

Day 4


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

Day 5 and Beyond

Renewal & Transformation

Your transformational journey is completed. Re-feeding beyond day 5 will fuel a better you.

Only through a prolonged fast can all these physiological effects be achieved, which is why the concept of fasting with food is so appealing.
