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.
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.

Yes — Amazingly, when you eat Fast Bar, your body thinks it's still fasting

Fasting 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.

Fasting 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.

Delicious + Healthy = Extraodinary

Fasting Bar is made with premium nuts like Macadamias. Nuts contain a variety of health-supporting nutrients like antioxidants, vitamins, minerals, fiber and Omega-3 fatty acids.

Fasting Bar’s recipe is designed to nourish your body while maintaining its fasting state. For that reason, it’s best enjoyed during either your morning intermittent fasting window or as a late-night snack to satiate you before bed.

Similar to water, our delicious flavors do not raise your blood glucose levels and keep your ketones in a fasting state*!
