Prolon is a science-driven nutrition brand focused on supporting healthy aging and longevity through evidence-based nutritional programs. Its flagship product, the Prolon 5-Day Diet, is a patented Fasting Mimicking Diet (FMD) developed from more than 25 years of research and 40+ published clinical studies conducted in collaboration with USC, Mayo Clinic, and Stanford, to help the body enter a fasting-like state while still providing carefully formulated nourishment that supports natural cellular renewal. The 5-Day Diet is a complete, pre-packaged nutrition program that includes portioned meals, snacks, and beverages for each day, making the experience simple to follow without calorie counting or meal planning. Clinical research published in peer-reviewed journals, including Nature Communications, found that participants completing three consecutive monthly cycles experienced an average 2.5-year reduction in biological age markers, while also supporting healthy metabolism, preserving lean muscle, and promoting fat loss. But the 5-Day Diet is only the beginning. The same decades of longevity research that gave rise to the FMD also informed Prolon's broader ecosystem of science-backed products designed for everyday life. This includes L-Biome, a precision probiotic formulated to support gut health and metabolic function; fast bars, developed to extend the fasting state between meals; nutrition shakes built around longevity-supporting protein ratios; and guided reset programs that combine multiple Prolon products into structured, longer-term health protocols. Every product in the Prolon line shares the same origin, rigorous peer-reviewed science, and the same goal: to give your body what it needs to function better for longer. Founded on the belief that nutrition should be grounded in rigorous scientific research rather than trends, Prolon develops all of its products using a research-first approach. Prolon is part of L-Nutra, a nutrition technology company dedicated to advancing evidence-based nutrition for healthy aging and longevity. Our mission is to make cutting-edge longevity science accessible to everyone because how you age is not simply something that happens to you. It is something you can actively shape.

This fast was excellent
This fast was excellent. I didn't love all of the foods, but the quality was there. It definitely helped me reset and get on track in order to get my GLP-1 journey going. I really liked having a fast that you actually eat foods with! Much more doable.

A good easy to follow weight loss tool…
Loved how the program was individually packaged by day and very easy to follow. It really did seem to burn fat as advertised and two months later I have kept off the 5 pounds I lost. I feel it did reset my metabolism, as I struggled to lose weight no matter what I did previously.

Started using FMD back in 2018
I started using FMD in 2018 when breast cancer was first found. I used for 6 consecutive months and I found it to be easy and I felt well. I used it every now and then, more to 'clean up my eating' which is easier to do after a 5 day FMD. Once I became metastatic (I'll always wonder if I kept with FMD if I could have avoided that 2nd diagnosis but life if full of 'woulda, coulda, shoulda' questions) I have found that side affects to the infusions are greatly decreased. Now, there are new flavors of soup which I love...and the 1 day fasts which I now do also. I love that I know that I am doing something good...not only for my body, but for my cells! And...it is easy, well researched and well supported with customer service people, texts, videos and FB.

Hi Sally,
Thank you for taking the time to share your experience.
We’re very happy to hear that you found the program easy to follow and complete, that most of the foods were surprisingly tasty, and that you did not experience excessive hunger during your round. At the same time, we completely understand your disappointment regarding the results and not noticing the level of changes you were hoping for.
Please know that our goal is always to ensure our customers feel supported and satisfied, and we are fully committed to finding the best possible resolution for you. I would really appreciate the opportunity to better understand the challenges you experienced with the program so that we can address them appropriately.
Each person is unique, and weight loss between rounds may vary based on several factors, including stress levels, dietary practices before or after the round, hydration, sleep, activity levels, or even the timing of your cycle. We also often hear from individuals who do not notice weight loss or changes until well after their round is completed.
It’s also important to note that the primary benefits of the 5-day Prolon fast are centered around cellular rejuvenation and metabolic support, while weight loss is considered a beneficial side effect. So even if you did not experience dramatic weight changes, your body may still have been receiving many of the fasting benefits.
In clinical studies, participants who completed one 5-day ProLon cycle per month for three consecutive months experienced an average weight loss of approximately 5.7–6 pounds by the end of the study, primarily from abdominal fat while helping preserve lean body mass.
Please feel free to reach out to us if you need any further support or if there is anything else we can do for you. You can contact us anytime at customerservice@l-nutra.com or by phone at +1 (888) 926-5370. We are here for you and happy to support you throughout your journey.

Hi Robbin,
Thank you for sharing your feedback with us. We understand that our program can be a significant investment in your health, and we truly appreciate you taking the time to share your thoughts.
We are committed to enhancing our offerings and making them as cost-effective as possible. We're dedicated to finding ways to ensure this product, based on 20+ years of scientific research, is as accessible as possible so more people can benefit from it. Please also keep an eye out for any promotions we may run in the future.
We also understand your feedback regarding variety. While we always aim to improve taste and diversity, it’s important to note that the soups were specifically designed and carefully formulated to help mitigate the potential adverse effects of intermittent fasting. Our research showed that carefully controlling energy intake and macronutrient composition can extend physiological ketogenesis similar to a water fast, while still providing energy and nutrients to increase fullness and satiety.
We truly appreciate your input and will continue working to improve both the experience and variety offered.
