Prolon Fasting Bars are plant-based protein bars formulated to nourish during fasting windows while helping the body remain in a physiological fasting state, with 5g of plant-based protein and 7g of fiber per bar.
These bars are made for people who want a convenient option during a fasting routine, particularly when hunger or cravings make it harder to maintain a fasting window. Their portable format suits mornings, travel and the later hours of a fast, as well as keeping a fasting-focused snack available at home or at work.
Prolon uses patented Fasting Mimicking Nutrition technology in a formula designed to provide nourishment while helping the body remain in a physiological fasting state. The low-glycemic formulation is also designed to help the body remain in a fasting state of ketosis during fasting windows. Prolon’s fasting bars are based on more than 25 years of fasting-mimicking research.
Each bar contains 5g of plant-based protein and 7g of fiber. The formula combines these with healthy fats and carbohydrates to provide satisfying nutrition in a convenient snack format. Chocolate chips, nuts and a hint of salt create a familiar chocolate chip flavor.
Prolon Fasting Bars are gluten-free, dairy-free and soy-free, and are labeled non-GMO and keto-friendly. Their blend of carbohydrates, healthy fats, fiber and plant-based protein is designed for fasting-focused snacking. The recipe uses nutrient-dense nuts as part of that blend.
This pack contains 24 bars for keeping a fasting-focused option available in different parts of your routine. Their portable format makes them suitable to have at home, at work or ready for travel, including for mornings, cravings or later hours of a fast.
These bars are suited to people looking for a portable, chocolate chip snack formulated for fasting-focused routines and made with plant-based protein and fiber.
