Fast Bar’s proprietary formula of premium ingredients doesn’t trigger your body’s nutrient sensing system, so your body’s tricked into thinking it’s fasting. It's the only thing you can eat during your fasting window without breaking your fast — eat without your body even knowing it.

Fast Bar - Intermittent Fasting Bars


Product options

Why to add fast bar to your day?
Fast Bar’s recipe comes from more than 20 years of research at the University of Southern California (USC). Scientists studied how unique blends of macronutrients and micronutrients could be consumed without kicking your body out of a fasting state. They used this formulation to create the Fast Bar, which provides the tasty nutrition of macadamias, pecans, almonds, and honey that has a similar fasting impact as a glass of water*. It’s also plant-based, Keto-friendly, and gluten-free.
Nutritional information
Fast bar secret ingredients
Fast bar nourishes your body with high quality plant base proteins, complex carbs (very low glycemic index) and is rich in healthy brain like healthy fats that we source from Macadamia, Pecans and Walnut, the most expensive ingredients that nature offers!
The secretive fast bar formulation is the fruit of two decades of collaboration between Nature and our Scientists who unlocked a natural nutri-technology of fasting with food or fasting mimicking diet. Recently, 14 global universities joined the research and helped us bring to the world the Fast Bar, Fasting Shake, Reset, and ProLon Five Days Fasting Nutirition.
