How ProLon® works daily

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.


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

Cellular Rejuvenation

Cellular cleaning/renewal & fat-burning continues.


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

The Benefits Continue After The 5 Days End

Cell-Proliferation begins and continues for up to 5 days after you complete the ProLon® Fasting Mimicking Diet® and return to your regular healthy meal plan.
