Scientifically identify cellular radars that detect nutrition, called Nutrient Sensing Pathways, and to develop a 5 day Nutrition Program that nourishes the body while the pathways are not triggered and therefore providing the prolonged fasting benefits.

Mostly Plant Based



Gluten Free

Rooted in Science

Over 20 years of extensive preclinical and clinical studies sponsored by the National Institutes of Health (NIH) and conducted at the Longevity Institute and Diabetes and Obesity Research Institute of The University of Southern California (USC) resulted in the development of the Fasting Mimicking Technology which is shown:

  • • High level of protection and stress resistance in cells
  • • Supports metabolic health
  • • Triggers autophagy - the clean-up of cellular debris
  • • Helps reduce visceral fat for a trimmer waistline

Backed by 20 years and $36 million in research & development

Clinical Study Methodology

Randomized controlled trial of subjects, completed 3 cycles of the ProLon Fasting Nutrition Program either in a randomized (n=39) or after being crossed over from a control diet group to the Fasting Mimicking Program group (N=32). Control subjects continued their normal diet. ProLon participants consumed the fasting mimicking diet for 5 consecutive days per month for three months. Measurements were performed prior to the diet (Before) and during the recovery period after the third cycle (After).
