ProLon Professional FAQ

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

ProLon Professional is for metabolic health. It is ideally suited to help those struggling to maintain healthy weight, visceral fat & waist circumference, body composition, and overall metabolic health.

Unlike ProLon Original and ProLon with Soup Variety 2, ProLon Professional contains less inulin, fewer grains and no night shades. Every ProLon Professional kit contains an all NEW vegan dark chocolate bar, and new soups without inulin and night shades that have been specially formulated for metabolic health. 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. Mediterranean Diet, 4 monthly cycles of 5-day FMD achieved many of the benefits of 120 days of continuous Mediterranean Diet, including significant 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 have been shown to help maintain lean body mass while reducing visceral fat, help promote 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 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. It is ultimately up to you and your healthcare provider to determine if you're 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 your healthcare provider or on using an HCP Code given to you by a licensed healthcare professional. To find a healthcare professional offering ProLon Professional in their practice, visit
