The ProLon Journey

Just 5 days to better health! What happens to the body over the 5 days of 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 & 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

Stem cell-based rejuvenation continues for up to 5 days once you complete the ProLon Fasting Mimicking Diet
and return to your regular healthy meal plan.

“I have now dropped 14 pounds… I have stayed on a very healthy diet after my first ProLon as it was the springboard for my transition to health and happiness. I had my blood test done pre and post and the results are very encouraging and I wasn’t unhealthy to start.”

Jake Orville
President and CEO at Cleveland HeartLab

“I love this program! I lost a few pounds to get ready for a photo shoot, but even better than that, I went 5 days without any added sugar. It felt like a miracle! During the 5 days on the program, I slept normally, had enough energy, & found the food absolutely delicious.”
