What is Fasting Mimicking?

Most people know the basic concept of fasting, but what is fasting mimicking?

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, however for many is to get through a prolonged fasting period (between 4-7 days) without food.

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

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


How it Works

Here’s what physical effects take place during the 5 days on the Fasting Mimicking Diet.

Fasting State

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

Fat Burning

ProLon guides your body to switch to a fat burning state. Cellular clean up (autophagy) begins.

Ketosis & Autophagy

Many reach a degree of the fat burning metabolic state known as ketosis. Cellular clean-up continues.

Cellular Rejuvenation

Cellular clean-up and fat burning continues.
