ProLon is a 5-day meal program that aims to boost your health with ‘scientifically developed foods.’ Its proprietary blend of ingredients claims to put your body in fasting mode, which scientific evidence suggests might be an effective form of weight loss. That being said, this program is not for everyone, and it could be dangerous to people with a low BMI.
Due to its intensity, our research team found that the program has strict guidelines and needs the approval of a medical professional before use. We examined ProLon’s components, side effects, and the testimonials of its users to get to the bottom of this weight loss program. Here’s everything we discovered.
First of all, ProLon is a 5-day meal program designed to nourish the body while “promoting regenerative and rejuvenating changes through scientifically developed, plant-based foods.”
Each meal comes in a box- one for each day (around 750 to 1100 calories per day). Inside these boxes, you’ll find a cornucopia of healthy, plant-based energy bars, snacks, supplements, beverages, and soups.
After the five days, the dieter is supposed to “transition for one day” and then go back to their regular routine.
The website claims that all of their food is scientifically studied and proven to give your body exactly what it needs to be as healthy as it possibly can, but what does the science specifically say about fasting?
CMAJ – There are some concerns with fasting, as individuals may “binge” during periods of time when eating is allowed.
PLOS One – Periodic fasting between 4 – 21 days is considered safe and can provide some benefits to emotional and physical well-being.
This “Fasting Mimicking Diet” allows you to get all of the amazing benefits of fasting without skipping your meals. You stay fuller, longer. They also claim that their foods promote positive changes within your body while making the fasting-mimicking period fun and safe for the customer.
We have to say, at first glance, we’re hopping on this wagon – scientific research and natural foods are a pretty good start in our eyes. But if you know us at all, you’ll know we’re not done until we get all the facts.
This is how much it costs to start on the respective program. We always recommend trying a product before making a large investment.

We scoped out their website and were impressed by the outstanding claims of scientific research and support from the National Institute for Aging and the National Institute of Health.
Their meal plans emerged after 20 years of research from the University of Southern California. They also claim their preclinical and clinical trials are performed at institutes like the University of Berlin, Mayo Clinic, Leiden University, and the University of Genoa.
The company offers an affiliate program for their products.

Since this is a proprietary diet, there’s not a complete list of ingredients. As we do understand this, it leaves a slightly bitter taste in our mouths. We like to know exactly what we’re getting.
We did put in some work and came up with the most detailed ingredient list that we could.
They offer nut bars that list ingredients such as macadamia nut butter, pecan, almond meal, honey, coconut, flaxseed meal, coconut oil, vanilla extract, sea salt, citric acid, ascorbic acid, mixed tocopherol.
Their Kale crackers consist of Golden flax seeds, kale, cashews, sunflower seeds, sesame seeds, nutritional yeast, apple cider vinegar, hemp seeds, dill weed, pumpkin seeds, sea salt, black pepper, and onion powder.
Their drinks contain natural vegetable glycerin, purified water, potassium sorbate, and natural flavor.
They offer a bevy of soups, containing combinations of; tomato concentrate, rice flour, potato starch, leek, quinoa, onion, olive oil, parsley, peas, yeast extract, savoy cabbage, carrot, zucchini, garlic, spinach powder, broccoli powder, sage, Champignon mushroom powder, celery, and turmeric.
The second variety of soups are butternut, tomato, butternut quinoa, white bean & spinach, and black bean.
Their dessert (Choco crisp bar) is made of brown rice, inulin, almonds, almond butter, cocoa powder, brown rice syrup, chocolate chips, rolled oats, rice dextrin, flaxseed oil, salt, and grape juice.
We’ve seen some lists of ingredients that vary slightly from what we came up with; again, this is a proprietary diet, and the ingredients aren’t all that certain.
How to Use (Take) Prolon
The healthy diet Prolon and exercise are in collaboration and need be taken for five back-to-back days, after which the user will progress for a day and resume their ordinary eating routine.
Guidelines and proper instructions are given in each package. A particular blend of nourishment is given every day for lunch, breakfast, supper, etc.
All nutrition given on a particular day must be used that day, as it were.
While a healthy meal missed can be set aside a few minutes during that day, there should be no trace starting with one day then onto the next.
The 5-day Prolon diet needs to be taken as regularly as is prescribed by the guidelines on the box.
The 5-day Prolon FMD can be purchased from different suppliers. Prolon prices range from $200 to $270 depending on your location and distributor.
Prolon claims to be the primary Fasting Mimicking Diet that gives you a blend of ingredients and foods ready to reinvent the body into a recovering and restoring mode, bringing about a balance and aging healthy.
Benefits of ProLon
So, what are the benefits of this fasting diet? We’ll list a few for you:
Regenerate: ProLon triggers a “natural multi-system regeneration,” which includes various benefits from anti-aging and more.
Speedy Weight-Loss: No extraordinary claim would be complete without the promise of quick and easy weight-loss. This is exactly what ProLon offers – except they say they have some scientific research to back it up.
Convenience: Of course, this diet is as convenient as anything. Each meal comes in its own “grab-and-go” box, making it simple to follow and even easier to access.
All-Natural: As we stated earlier, the ingredients and foods in this diet are all-natural, using plant-based ingredients like fruits, nuts, seeds, and veggies.
Potential Prolon Side Effects
In the study and research analysis, most members proclaimed few minor or no unfavorable side effects for the fasting days, although none of these side effects were indicated.
In any case, the organization highlights in a few places that Prolon isn’t for everybody and should just be utilized by adults over age 18, and they should be healthy and strong.
Outside of what’s provided in each box, the organization underlines that no extra multivitamins or supplements must be taken within the fasting or diet period.
Also, unless stated by an authorized doctor, Prolon should never be used with any medications.
Details on Prolon and Weight Loss
The 5:2 diet (in taking just 600-700 calories two days per week) aids with weight loss and the company claims the body desires to fast for a good long period without eating so that it goes into safe and secure mode, which is how human beings survived for tens of thousands of years.
The advantages of ensuing an FMD are countless: although weight-loss will unquestionably happen, the key aim is to cover your Life Span-Aging – that is, just how long you live a comfortable and healthy life, before facing any aging disorders.

The Science of ProLon
If I were writing a book right now, it would be called The Science of ProLon; I would have no shortage of scientific studies and research to fill my book to the brim.
The L-Nutra website claims there’s research backing everything – the company even offers relevant science, similar to the research backing the Sirtfood Diet.
It went on to say that three cycles of 5-day fasting-mimicking diet were deemed safe and effective.
Remember when ProLon claimed it could help regenerate your body? There is a study with some pretty interesting findings.
Now, we realize that not all of the studies are about this diet specifically, but if you’re anything like us, you seriously appreciate some solid research behind a product’s claims.
Where to Buy
Where to Buy Prolon
Things get a bit tricky when you consider purchasing this diet plan for yourself. You can’t exactly hop on Amazon and purchase this program – you need to pass a test of sorts. You can check the official website for more information.
That’s right; there are extraordinary claims and unbelievable scientific backing ProLon. But, not everyone can purchase it – there’s an exclusion criterion. Speak with a physician before starting anything.
After speaking with a doctor, approval for ProLon comes in four ways:
Take a Health Self-Assessment Survey
Take a survey to find out if ProLon mimicking diet is the right choice for you. After taking the survey, it may tell you that you need to speak with a doctor first. If you meet the criteria, the only other step is to schedule a phone call with a dietitian or nurse practitioner.
Health Care Provider Evaluation
You can call the ProLon information line, speak with a professional, or get approval from your physician.
Use the HCP Code from a Health Care Provider
Once you speak with a doctor, they will provide you with a code. Use this code to finish your registration and to order your ProLon.
Doctor’s authorizations and approval codes.
No Medical Conditions
There is an option to check that you have no medical condition or age restriction preventing you from trying Prolon.

What Users Are Saying
What Users Are Saying
“I truly loved the ProLon experience. The food was good for what it was and I was able to complete the five day fast with very little discomfort. The 2nd day was probably the worst. I can’t believe how clear headed I became. I felt like I could go on and on with the fast and I was almost sad to see it end. I can’t wait to do it again.”
“Too expensive for what it is. You can do this on your own in a more healthful, practical, and way less expensive manor. Eating all the powdered processed soup messed my system up pretty good. I was constipated and had headaches for days after finishing. I have since done calorie restricted ‘fasts’ with similar calorie counts and macro nutrients but incorporating real food and have had all of the benefit but none of the negatives. It is way over priced for what you get! Don’t waste your money.”
“I appreciate how great I feel at the end of this program and have done it three times. I think it would be great if we could choose our soups. By the end of the program I am a bit bored of the same choices repeated. It would be nice if we could pull from the other kit or mix and match.”
The Bottom Line on ProLon
If you asked yourself, “Is ProLon for me?” you wouldn’t be alone. We’ve noticed a large amount of interest surrounding this diet. There are also bloggers and reviewers chomping at the bit wanting to try it out for themselves. But, we’re just not 100% sure.
Of all the means of losing weight, making lifestyle changes tends to be the most effective. However, long-term lifestyles changes are difficult and can make it hard to stick with a plan. That’s where we found technology picks up offering continuous support.
