A full fasting day, while you eat

Extends your fasting window

Plant-based, nutrient-dense

Made with almonds, macadamias and pecans, rich in healthy fats, fiber and omega-3s, with a low glycemic index.

Like magic—but proven by science
The results of a randomized controlled study show that the Fasting Bar has comparable effects on ketones and blood glucose levels as a water-only fast, meaning that it doesn’t disrupt the fasting state. This shows the effectiveness of the Fasting Bar in extending your fasting periods while allowing you to enjoy a nutritious and satiating snack.
