The ProLon Journey

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.


Your transformational journey is complete. Re-feeding beyond Day 5 will fuel a Better You.

The Benefits Continue After The 5 Days End

Emotional and physiological benefits continue after using ProLon.

I'm hooked!

What a lovely way to "fast." The meals were tasty and satisfying and felt like a wonderful reset that I was looking for. I purchased another cleanse box the day after I finished! If that doesn't speak for itself...


Feeling great!

Feeling light and reset after my first fast. Going to make this diet a part of my life on a regular basis now. I highly recommend Prolon!


It's my third time using ProLon

This is my third time using ProLon. I love everything included in the box. I feel fantastic after I do it. I will definitely continue to use the program.


Very doable fasting diet

Very doable fasting diet. Eighty percent of the time I wasn’t hungry. I was able to cook meals and not feel tortured by the cooking smells. The prepared soups and snacks are tasty and it’s surprising how little you need to feel relatively satisfied on this fast.
