The ProLon® Fasting Mimicking Diet® is the only 5-day dietary program shown through clinical trials to nourish your body while triggering the natural process of cellular clean-up and rejuvenation associated with fasting. Users typically experience greater energy and focus, better sleep, a slimmer waistline, and an improvement in their relationship with food, finding themselves satisfied with smaller portions and experiencing less cravings. ProLon® meals come in 5 small boxes (one for each day) that include plant-based energy bars, soups, a variety of snacks, drinks, and supplements, all studied and carefully designed to nourish your body while keeping it in a fasting state for benefits from the inside out.
