“I love the science supporting ProLon, and I love that the science has been published in multiple peer reviewed journals. It allows me to suggest ProLon with confidence. I have used fasting and time restricted eating in my practice for years; ProLon augments this and takes it to the next level.”

“ProLon carries so many weight, metabolic and cellular benefits that not only do I recommend it, but I decided to join the company’s mission full time as Chief Medical Officer”

What does the 5-Day Meal Kit contain?

The meal kit comes with 5 days of ready-to-eat food, with 4 meals each day. Plant-based, it includes crackers, healthy food bars, soups, and others.


It offers great convenience and minimal cooking (only with the soups), meaning that each day you can simply grab a box and eat anytime and anywhere, be it at the office or at home. 

ProLon is offered in 2 flavors - with the only difference being the choice of soups. Both lead to the same clinical benefits.

A house-cleaning for your body at the cellular level

In simple terms, ProLon induces a "house-cleaning" in your body by removing old, sluggish components and recycling them into creating new, healthy cells. This "repairing" at the most fundamental cellular level leads to the many benefits such as fat loss, improved metabolic health and improved blood glucose. Users also report better concentration and reduced food cravings during and after the diet.
