Fasting with Food?

The Fasting Mimicking Diet® (FMD®) is a carefully formulated nutrition program that nourishes the body with plant-based proteins, fiber rich carbs and healthy fats, and goes undetected by cellular food sensing paths to keep your body in fasting mode.

The Fasting Mimicking Diet®

Two decades of research on fasting has shown that four to five days of fasting are ideal to encourage cellular rejuvenation. Inventors from the University of Southern California developed this nutrition program to help you reap many benefits of a five-day fast without the deprivation. Experience weight loss*, metabolic balance and cellular rejuvenation. This is what makes the FMD unique and effective for healthy aging and prevention.

What Can You Expect from The Fasting Mimicking Diet®?

Some of the benefits you may experience include:


There is no faster way to lose fat (especially belly fat) while protecting lean body mass.


Enhances autophagy (the clean-up of worn out cells).


Enjoy greater focus, clarity, and energy.


In a clinical study, users lost weight and maintained healthy systolic blood pressure *.


Most of those who completed their first ProLon reported they felt more motivated to adopt a healthier lifestyle, establish better eating patterns, and be more mindful of what they eat.

*In a clinical study, ProLon is shown over three cycles to help individuals lose an average of 5.7 lbs and 1.6 inches off their waist circumference. Individual results may vary.


Meet the Creator of The FMD

Valter Longo, Ph.D

Dr. Valter Longo is the Director of the Longevity Institute at the University of Southern California. He is the grandfather of the science of fasting and was named by TIME among the top 50 most influential people in Health.

Prof. Longo was awarded for the Fasting Mimicking Diet® (FMD®) the first patent in history for ‘Promoting Longevity and Healthspan’. He discovered first how cells sense food and then devised the fasting mimicking formulation and finally conducted mice and human trials to test the health benefits of the Fasting Mimicking Diet® (FMD®).

Fasting Mimicking Diet® vs.
Intermittent Fasting vs. Ketogenic Diet

Intermittent Fasting is a practice of water-based fasting or eating less than 500-600 calories for a 24-hour period. Benefits can include weight loss and some metabolic balance. Its limitation is its need for frequency, and it doesn’t extend long enough to stress the cells to restructure and rejuvenate. Our FastBar® helps curb the hunger and nourish the body with intermittent fasting.

The Ketogenic Diet is rich in fat, low in carbs and normal or low in proteins. Some of its benefits include blood sugar balance, certain brain conditions, and more. Its limitation is that it needs to be observed every day for weeks. Also, because of the protein levels, the cells recognize food, so they don’t enter deep fasting stress in order to regenerate.

The Fasting Mimicking Diet® is carefully designed to closely mimic fasting, providing weight, metabolic and cellular benefits for healthy aging. Its limitation is that it shouldn’t be done for long periods of time, but can be done in cycles two to six times a year, with normal food intake after each five-day cycle.

Scientific Breakthrough Technology

The ProLon FMD is the result of more than 20 years of extensive preclinical and clinical studies spearheaded by Dr. Valter Longo. Funders include the National Institutes of Health (NIH), and research collaborators include Mayo Clinic, Keck Hospital, Indiana University, Leiden University, University of Genoa, IFOM, University of Heidelberg, Milan University and other top global research centers.

L-Nutra licenses the FMD technology they test to bring it to you as a life changing intervention. L-Nutra then donates a portion of our proceeds to the Create Cures Foundation for nonprofit and charity work around the world. Over $700k was donated in 2017-2019.
