1. What is ProLon®?
ProLon® is the first Fasting Mimicking Diet® (FMD®) developed to provide the beneficial effects of fasting by making the fasting mimicking period safe and pleasant. ProLon®, which contains plant-based soups, bars, crackers, olives, drinks, and supplements, is a proprietary 5-day dietary program, providing approximately 750 to 1100 calories per day. It is based on innovative research carried out at two of the world’s leading centers for biomedical and longevity research located at the University of Southern California (USC), the Longevity Institute and the Diabetes and Obesity Research Institute. This revolutionary meal plan has been scientifically designed and clinically tested to mimic the effects of fasting, while providing the proper daily nourishment and the feeling of satisfaction.
2. What does a "Fasting Mimicking Diet®" mean?
A Fasting Mimicking Diet (FMD®) is a high nutrition, low protein, low carbohydrate meal plan, clinically proven to beneficially change a wide range of biomarkers associated with aging, poor health, and inflammation. (See Question 3).
3. Who should engage in the ProLon® dietary program?
ProLon® was shown in clinical trials to have beneficial effects on a wide variety of markers: it decreases abdominal fat while increasing relative lean body mass, decreases fasting glucose, reduces C-reactive protein (a marker of inflammation), and reduces IGF-1 (associated with increased DNA damage mortality and aging in humans).
4. How should the ProLon® Diet be taken?
The diet should be taken for 5 consecutive days, after which the patient will transition for 1 day and then resume their normal diet. Instructions are provided in every carton. A specific combination of food is provided on each day for breakfast, lunch, dinner and snacks. All food provided on a specific day should be taken on that day only. While a meal missed can be made up at any time during the same day, there should be no carryover from one day to the next. The 5-day diet should be taken as often as is recommended by the healthcare professional.
5. How much weight does one lose and will the individual be able to keep it off?
The amount of weight loss varies by individual. A healthcare professional will be able to discuss this during consultation and work with the patient on meeting weight goals.
6. Can ProLon® be used by individuals with chronic illness or disease?
Depending on the medical illness or disease, past medical history, and current medications, the ProLon® dietary program might be combined with the standard of care treatment; however, ProLon® cannot be prescribed to prevent or treat diseases. Contact the healthcare provider most familiar with the illness or disease to discuss the ProLon® dietary program.
7. Should routine intake of supplements during the dieting period be stopped?
As the ProLon® dietary program is designed to provide all of the supplements and nutrients needed, no additional multivitamins or supplements should be taken during the diet period; however, the options should be discussed with the supervising healthcare professional.
8. How does an individual participate in the ProLon® dietary program?
The ProLon® dietary program should be administered under the supervision of a licensed healthcare professional (HCP), e.g. Medical Doctor, Doctor of Osteopathic Medicine, Physician Assistant, Nurse Practitioner, a Doctor of Integrative Medicine, Anti-Aging Specialist, Naturopath, Chiropractor or Registered Dietitian. As this is a low calorie diet, that supervising HCP must clear the individual to participate in the program. If the HCP does not feel qualified to clear the patient, they should seek clearance from a qualified HCP, such as a medical doctor. In addition, they should determine if the individual has any known medical conditions, and if so, obtain medical clearance from the HCP treating the patient’s condition before initiating the ProLon® diet.
9. How does a physician sign up on the website?
We are currently working on a portal for HCPs, in the meanwhile please reach out to us by sending an e-mail to firstname.lastname@example.org
10. Why do some individual need "Supervision from a Health Care Provider"?
Healthcare professionals will determine if a low-calorie and low-protein diet lasting 5 days would be safe for individuals based on their medical history and health conditions. The supervising physician will educate the individual about potential side effects, and provide contact information to enable the patient to contact him/her if any medical condition arises.
11. How many ProLon® cycles can be consumed in a year?
This depends on the individual’s baseline markers and health measurements, assessment and recommendation of the healthcare professional; for the majority of relatively healthy individuals, 3 to 4 times a year is sufficient. By contrast, for individuals with high levels of multiple biomarkers for aging, cholesterol, IGF-1, CRP, blood pressure, abdominal fat, etc., the HCP may decide to recommend 6-12 ProLon® cycles a year. For very high risk individuals, it may be given as often as every 15 days.
12. Once someone starts the ProLon® cycle can they split up the days?
Splitting up days is not recommended since this method is believed to be much less effective than the 5 consecutive days.
13. Is there a 'Transition Day' diet for patients after completing the ProLon® diet?
On Day 6, after the ProLon® diet ends, users should avoid binge eating and resume their normal diet gradually. They should start with liquid foods, such as soups and fruit juices, followed by light meals, including rice, pasta and small portions of meat, fish and/or legumes. A normal diet can be resumed on day 7, or 24 hours after the end of the ProLon® diet.
14. Is there scientific data to prove the ProLon® dietary program allows patients to reach as "fasting state"?
The results achieved with ProLon® in clinical trials were very similar to those achieved with fasting. However, ProLon® is safer, providing vital nutrition during the 5 day diet.
15. How should an individual monitor themselves?
We suggest you track your weight, blood pressure, and abdominal circumference before starting and after each cycle of the diet.
16. Is there scientific data supporting ProLon® ingredients and formulation?
The proprietary dietary formulation is based on decades of scientific research, including pre-clinical and clinical trials and contains specific ingredients that were put together to mimic fasting, while optimizing nourishment.
17. Are all the components of the diet considered organic?
The meal plan contains some products that are made with organic ingredients, but they are not certified organic. Our food products are all plant based, with the exception of honey in our bars.
18. What other foods can one consumed while on ProLon®?
The ProLon® dietary program provides all one needs for nourishment during the 5 days, while letting the powerful self-repair and rejuvenation mechanisms work, no extra foods or drinks (other than water and decaffeinated tea) should be consumed while on ProLon® to avoid reducing its efficacy.
19. Can one consume coffee while on ProLon®?
Decaffeinated coffee is OK on the diet, but do be mindful as some do contain small amounts of caffeine which can interfere with the beneficial effects of the diet.
20. What can patients do if they are hungry during the 5 days?
Because the ProLon® diet is low in calories, hunger may occur during the 5 day diet period. Most clinical trial participants only experienced a low level of periodic hunger. If hunger is severe, the patient should contact their healthcare professional. In such cases, one may want to consume a food that is not highly caloric, such as a slice of an apple. Remember, this diet is only for 5 days. Feeling hungry is normal if one’s normal diet consists of high calories. People generally reported that the hunger subsided by day 3 or 4.
21. If extra calories throughout the day are needed, what should one consume?
One should not eat anything extra while on the ProLon® dietary program. Since this diet is low calorie, one may experience the feeling of slight weakness and possible dizziness as the body adjusts, especially on Day 2. This is normal. Usually by day 3 this decreases; however, should the symptoms be severe, one can drink fruit juices and call your doctor. The supervising healthcare professional should then review if it is safe for the patient to continue on the diet. The energy drink provided in the diet boxes, to be taken throughout the day, provides not only nutritional support during the diet, but can be specifically helpful in these instances.
22. Can one substitute different flavours of tea while on ProLon®?
There are different flavors of teas provided with the diet. Although not recommended, since the ProLon® teas are selected for specific properties and have been clinically tested, if for some reason one does not want to consume one of these flavors, a substitution can be made. A substitute tea should have no caffeine or additives, and should be taken without sugar or cream.
23. If all of the food is not eaten for the day, is it ok?
Yes; however, since this diet has been clinically tested, one should make every effort to follow the program to minimize malnourishment and safety issues. Just document the foods not eaten and inform the supervising healthcare professional.
24. What if one meal is missed, can it be taken later on the same day?
Yes, if a meal is missed, it can be taken later on the same day; but do not take a missed meal on a different day. (See Question 25.)
25. If all the food is not eaten on one day can it be eaten on the next day?
This is not advised; the foods provided should only be consumed on the day for which they are designated; however, if feeling lightheaded, dizzy or having any other side effects, consuming one of the leftover diet foods would be preferable to consuming something else. Note: the ProLon® diet does not have extras in the meal box. (See Question 21.)
26. Can the diet be stopped at day 4?
The positive effects of the ProLon® dietary program tested in the clinical trials require 5 consecutive days. Therefore, the diet should be maintained for the full 5 days. If the diet must be discontinued earlier, however, the healthcare professional should be informed.
27. What if food outside the ProLon® diet was eaten during one day of the diet because of circumstances (e.g. social events)?
The diet is formulated based on specific nutritional, scientifically proven benefits. Therefore, it’s very important to follow the diet closely. However, if this happens on one occasion, do not worry—continue with the ProLon® dietary program for the rest of the 5 days.
28. What are the options if one does not like certain ProLon® food items?
It depends on the food item. For example, if a soup is disliked, lemon/lime and herbs can be added in small quantities. If a tea is disliked, a different tea can be substituted, provided it is non-caffeinated, non-sugared, preferably with no added color or preservatives.
29. Can fresh herbs be added in the soups?
Yes, herbs and lemon in small quantities may be added to taste. Please note that the diet is specially formulated to provide a specific amount of nutrients and calories.
30. What is DHA?
DHA stands for docosahexaenoic acid and is an omega-3 fatty acid. DHA is essential for normal brain function.
31. What is the energy drink for?
The energy drink is specially formulated to provide vegetable-based nutritional support during the diet.
32. What is the energy drink made from?
The energy drink is made from plant-derived glycerol and water. This selection is the result of years of studies to maximize safety and nourishment without interfering with the beneficial effects of the diet.
33. What is it in the food that makes it "anti-ageing"?
The unique design and combination of ingredients in ProLon® enables the diet to promote the generation of an increased number of stem cells and a wide range of “anti-aging” effects, some caused by nourishment and some caused by triggering rejuvenating effects.
34. Can I participate in the program if I have a history of allergy or may be gluten or lactose sensitive?
Our ProLon® Fasting Mimicking Diet is Lactose and Gluten Free. Individuals with allergies to nuts, soy or tomato should avoid consuming the current version of ProLon®.
35. What is the recommended "healthy" or "normal" daily calorific intake?
We recommend you discuss your ongoing diet with your healthcare professional. They can review your current intake and give you specific guidelines to follow based on your height, weight and gender. During the 5 day ProLon® dietary program, approximately 1100 calories are consumed on Day 1 and 750 calories on Days 2-5.
36. If an individual buys multiple boxes of ProLon® for several cycles at once and after the first cycle using ProLon® they do not wish to continue, will this individual get a refund for the remaining boxes of ProLon® purchased?

37. What are the potential side effects of a 5-day fasting mimicking diet?
While many people do not experience significant side effects during the 5-day fasting mimicking diet, by the second or third day, some individuals report experiencing symptoms frequently seen with other prolonged fasting or ketogenic diets that may include:
Less common side effects may include:
- Brain fog
- Gut changes including constipation or diarrhea, and rarely nausea
- Muscle soreness
- Sleep difficulty
- Sugar cravings
Most of these symptoms are self-limiting and resolve either during or immediately after completion of the diet; however, for some they can last up to two weeks.
While autophagy—the breakdown and recycling of old damaged cells—may be responsible for some of these side effects, another probable cause can be what’s known as the keto flu.
The keto flu and its ill effects are caused by the body’s transition from burning sugar to burning fat for energy. Although it’s a temporary and natural reaction to entering ketosis, the symptoms can be too debilitating for some to get through.
Potential Remedies for the Keto Flu
Methods you can use that may ease symptoms of keto flu:
1) Stay hydrated (drink at least 64 fluid oz of water each day)
2) Increase electrolytes like sodium, potassium and magnesium, which will help you hold onto the water you’re drinking (you can add Himalayan sea salt to the soups, or drink a zero-calorie electrolyte water)
3) Get plenty of sleep on a consistent schedule (do your best, but it isn’t a problem if you don’t stay asleep the entire night)
4) Avoid strenuous exercise and activities, as these may increase the demand for energy and worsen symptoms.
