The ProLon® Fasting Mimicking Diet® is a proprietary plant-based restricted-calorie meal program that has been scientifically designed to provide the rejuvenative effects of fasting at the cellular level, while still providing the body with nourishment.

ProLon® is intended for use by healthy individuals who want to enhance their health and well-being and by individuals who struggle with weight and want to proactively manage their weight in an easy and healthy way.

FMD® provides the body with a scientifically developed combination of macronutrients (fats, carbohydrates, proteins) and micronutrients (essential vitamins and minerals) designed to keep the body nourished while going through the rejuvenating process of the fasting state.

The diet should be taken for five consecutive days, after which the individual will transition on the 6th day and then resume their normal diet. The program provides a meal card that recommends how to consume the items for each day, but each day’s items can be consumed in any order you wish, as long as you only eat each day’s items during that day (do not carry them over to the next).

While the purpose of the diet is to trigger rejuvenation, weight loss may occur. Everyone is different, and weight loss depends on a number of factors. In a clinical study of participants who completed a 5-day ProLon® cycle once a month for three months, the average weight loss at the end of the study was about 5.1 pounds. This was primarily abdominal fat, while lean body mass was preserved.”

It is best to avoid non-prescribed additions to the protocol, including dietary supplements. The clinical studies did not include additional ingredients, and we are still learning what effect these additions may have on the protocol. For prescribed medications and dietary supplements, we recommend consulting with your physician or healthcare provider.

If you have a medical condition, then you must reach out to a healthcare provider to determine your suitability for ProLon®.

Fasting on a restricted diet for 5 days is not for everyone. In certain situations, a healthcare professional can help determine if ProLon® is a safe choice.

We recommend to follow the clinical trial once per month for three consecutive months. After completing the 1st three cycles, you can do the program from time to time when you are looking for rejuvenation.

The ProLon® diet has been carefully curated and scientifically tested to be consumed consecutively. Therefore, we do not recommend rotating boxes or food items between days.
