ProLon® mitigates the burden and danger of water-only fasting while responding to the unmet need for a readily consumable, proven, and safe dietary program that does not require ongoing lifestyle changes. The meals come in five boxes that include plant-based energy bars, soups, various snacks, drinks, and supplements, all studied and carefully designed to nourish the body and promote weight loss and positive changes. The ingredients are 100% plant-based and do not contain any additives, preservatives, or chemicals. The daily caloric intake with ProLon® is between 770 and 1100 calories. The five-day meal program is recommended once a month for three consecutive months with a standard diet between the weeks of taking ProLon®.
