I have done this fast 4 times. The good side is I have lost 4-5 lbs each time, the bad side is it’s truly hell and not because you’re suffering from hunger, but because the taste is so intolerable.... Toon meer

Geschreven door het bedrijf
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.

Hard to cancel and a very deceptive
Hard to cancel and a very deceptive, subscription plan. You will likely be signed up for a subscription, make sure to cancel as you will not likely do package again. The fast is not worth the money and could be done on your own. The meals are terrible.

So Far So Good
I had a discovery call with the dietition and that went very well. She was very knowledgeable, kind and helped solve things that would have been a block for me personally.
I later had a couple more questions, so I call the number she gave me, and I left a message. I received an email very shortly after, with a direct line to customer service. I call that number, spoke with the gentleman, he answered all my questions in detail. He also was knowledgeable. He was also kind and patient. Neither person put pressure on me, and were professionally friendly. I think customer service person's name is Manuel.
So I'm off to a great start.

Hi Brett,
Thank you so much for sharing your experience with us!
We're delighted to hear that you enjoyed your first 5-day fast and found the experience positive. It’s always wonderful to hear from customers who feel empowered and encouraged to continue incorporating Prolon into their wellness journey.
Many of the clinical studies on the fasting-mimicking diet were conducted using monthly cycles for the first three months, followed by less frequent maintenance cycles depending on individual goals. We're excited to hear that you're considering repeating the program every few months and making it part of your long-term health routine.
Thank you again for your kind words and for being part of the Prolon community. We look forward to supporting you on your future fasting journeys.

I haven’t received anything yet but email after email — you want me to recommend something I haven’t even received? So far this business has a 10/10 for being annoying and over-marketing. Unless that stops I’ll cancel my subscription.

Hi Susan,
Thank you for taking the time to share your feedback. We sincerely apologize for the frustration this experience caused.
To provide some context, Prolon sends an initial review request shortly after an order is placed to gather feedback on the ordering experience, website, shipping process, and customer support. A separate follow-up review is sent after customers have had the opportunity to receive and try the product, so they can share feedback on the program itself.
Our goal is to keep customers informed and supported throughout their journey. However, we completely understand that communication preferences vary. Customers can unsubscribe from marketing emails at any time using the link at the bottom of any email, though doing so may also prevent them from receiving fasting tips, educational resources, coaching updates, and other program-related support.
Our Customer Service Team has reached out directly to learn more about your experience and help address your concerns. We truly value your feedback, as it helps us continue improving the experience for all of our customers.
