ProLon Professional FAQ

ProLon Professional is a 5-Day meal program that is designed to nourish the body while providing many of the positive effects of a fast. It’s only available to healthcare providers who offer metabolic health programs, and it has been thoroughly researched and clinically tested including a clinical trial of ProLon versus an everyday heart healthy diet.

ProLon Professional was designed to support metabolic and overall health for healthy aging. It is ideally suited to help those struggling to maintain healthy weight, reduce visceral (belly) fat & waist circumference*, improve body composition, and maintain overall metabolic health.

*Benefits seen in a clinical study of the 5-day ProLon cycle once a month for three months

Unlike ProLon Original and ProLon with Soup Variety 2, ProLon Professional contains less inulin, fewer grains and no nightshades. Every ProLon Professional kit contains an all NEW vegan dark chocolate bar, and new soups without inulin and nightshades that have been specially formulated for the benefits of metabolic health, healthy aging, weight loss, and more. ProLon Professional is only available to healthcare professionals who are able to manage metabolic health programs.

Fasting Mimicking Diets have been extensively researched and clinically tested. In a clinical trial of ProLon vs. a daily heart healthy diet, 4 monthly cycles of 5-day FMD achieved many of the benefits of 120 days of continuous heart healthy diet, including weight loss and reduction in waist circumference, and supporting metabolic health, as well as helping with hunger, cravings and satiety.

Additionally, 3 cycles of ProLon used over 3 consecutive months have been shown to help maintain lean body mass while reducing visceral fat, help healthy aging, and to initiate cellular clean-up (also known as autophagy).

Surveys conducted after 1 cycle of FMD show that people feel more motivated to adopt a healthier lifestyle, and have fewer cravings, more energy, and greater mental clarity and focus.

The diet should be used for 5 consecutive days per month (30 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 eaten 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. It is ultimately up to each healthcare provider to determine if a patient is healthy enough for a 5-day fast or FMD, and whether/how often you should consider repeating the diet.

The proprietary dietary formulation is based on decades of scientific research, including preclinical and clinical trials, and contains specific ingredients that were put together to mimic fasting, while optimizing nourishment.

ProLon Professional can only be purchased directly from a healthcare provider or through a healthcare provider's website using an HCP Code provided to you by a licensed healthcare professional. To find a healthcare professional offering ProLon Professional in their practice, patients can visit
