Fasting Nutri-Technology: A Groundbreaking Innovation


Nourishment for Our Skin's Longevity

The skin, the largest organ in our body, mirrors our inner health. Its vitality, radiance, suppleness, and healthy against aging rely predominantly on the nutrition we ingest, more so than the creams we apply. Optimal nutrition impacts the whole skin surface of our body, not just the face and neck, representing merely 3.5% of the total skin.

New Evidence: Skin, Confidence, & Happiness

On February 21, 2023, the Journal of Clinical Medicine published the skin and emotional results of a randomized clinical study on ProLon's 5-Day Fasting Nutrition. The study recruited 45 healthy women aged between 35 and 60 and found that the group that used ProLon three times over three months (5 days per month) reported significant improvements in skin hydration, health, texture, and roughness even after the first cycle. Moreover, study participants reported statistically significant improvements in confidence and happiness levels.

ProLon Regimen: The Science & Patents

ProLon's 5-Day Fasting Mimicking Diet, backed by over 30 clinical trials, is known for its benefits on metabolism, cardiovascular health, and supporting healthy aging. Recognized by the US and European patent offices with over 40 patents, including one for enhancing rejuvenation and longevity, the secret of ProLon lies in its formulation that does not spike pro-aging factors in the blood and goes undetected by the cells. Indeed this precision formulation is made of plant-based clean ingredients that do not trigger the Cellular Nutrient Sensing Pathways, tricking the cells into believing they are fasting while they are nourished. This Novel fasting with-food method induces physiological fasting and its benefits while the body is consuming nutrition.

Many ProLon users report emotional benefits such as improved confidence, happiness, mental clarity, energy, and sleep. Additionally, they often experience a change in their relationship with food, expressed as lower cravings, reduced late-night snacking, and less need for large food portions. The ProLon 5-Day Fasting Nutrition was even awarded in 2022 as one of the best three products for employee wellness.

Unveiling the Secret

The secret lies in Autophagy–a biological miracle rooted in our epigenetics, observed in our ancestors and contemporary centenarians (people living 100 and beyond). Autophagy, a cellular cleansing, detoxing, and rejuvenating process activated by fasting, is a practice that was prevalent in our ancestors' lives. With our current dietary habits, the practice of fasting has been lost, and our cells, including skin cells, have started to age biologically faster, losing their vibrance and hydration.

For over a decade, the National Institute for Health has sponsored researchers at the Longevity Institute of the University of Southern California to develop a specialized 5-day diet that supports people to eat a healthy plant-based, gluten-free, low glycemic index formulation that mimics fasting in the body and provides its benefits. This novel fasting-mimicking formulation was then examined by 18 universities to showcase its myriad health benefits.

L-Nutra Reports First-Ever Study Showing ProLon® Improves Skin Health, Happiness, and Confidence

SANTA MONICA, Calif., February 27, 2023 ( - L-Nutra Inc., a leading nutrition technology company that pioneers the discovery, design, and commercialization of novel nutrition programs that impact cellular rejuvenation and support healthy aging, announced the results of a first-ever study evaluating the impact of its Fasting Mimicking Diet (ProLon®) on skin hydration, texture, and psychological well-being in women.

The study, which was published in the Journal of Clinical Medicine, is the first randomized controlled trial demonstrating the efficacy of a five-day Fasting Mimicking Diet (FMD) Nutrition protocol on enhancing skin quality, smoothness, hydration, and key components of psychological well-being. Skin health and mental wellbeing are common concerns among women, and this research provides compelling evidence for the effectiveness of FMD Nutrition in improving overall health. 

"This study demonstrates the holistic and systemic impact of the Fasting Mimicking Technology affecting cellular rejuvenation from as deep as the inner organ systems to the surface tissue like skin. Together with other published FMD studies in diabetes and cancer, this research further validates that FMD Nutrition is a powerful tool in Lifestyle medicine to improve overall health," said William Hsu, MD, Chief Medical Officer of L-Nutra Inc. 

The researchers recruited 45 female participants, ranging from 35 to 60 years old. The group that used the FMD Nutrition five days per month for three consecutive months had significant improvements in skin hydration as measured by Corneometer, as well as maintenance of skin texture, smoothness and tone evenness, compared to individuals in the standard of care group. Participants also reported significant improvements in feelings of happiness, confidence and empowerment to take control of their health, as well as optimism about the future. 

 "This successful clinical trial is another testimony for the rejuvenative power of the Fasting Mimicking Diet. Our goal is to help everyone live a long and healthy life by keeping our biological age younger than our chronological age. Through this trial, we have demonstrated what many of our ProLon® consumers have reported for years, a healthier looking, glowing skin, which helps people around the world feel happy and confident about their lives," said Joseph Antoun, M.D., Ph.D., CEO and Chairman of L-Nutra Inc.
