Blaze Pizza is about to became the first national pizza chain with an official Keto diet-approved crust.

On Monday, the fast-casual pizza chain announced the launch of the Keto Crust. The crust contains just six grams of net carbs, swapping flour for ingredients like flax seeds, eggs, and cheese.

"Pizza crusts are traditionally made mostly of flour, water and yeast," executive chef Brad Kent told Business Insider. "Removing the flour brings several challenges since the gluten and starches and sugars (carbohydrates) deliver the desirable light, crispy, and chewy texture in addition to its toasty and yeasty flavor."

Blaze is also rolling out a new cauliflower crust. The two new crusts serve as the bases for the line of Life Mode Pizzas, which will hit menus on Tuesday along with the crusts.

Here is the new lineup of pizzas, which will be available for order online and via app:

• Keto Pizza: Keto Crust, spicy red sauce, mozzarella, ovalini mozzarella, bacon, cherry tomatoes, mushrooms, spinach
• Protein Pizza: Keto Crust, red sauce, mozzarella, Italian meatballs, smoked ham, grilled chicken, black olives, green bell peppers, oregano
• Vegan Pizza: Original dough, red sauce, vegan cheese, spicy vegan chorizo, mushrooms, red onions, green bell peppers, basil, olive oil drizzle
• Vegetarian Pizza: Cauliflower Crust, red sauce, mozzarella, ricotta, artichokes, Kalamata olives, red onions, spinach

A number of brands have tried to win over people on the high-fat, low-carb Keto diet this year. In January, Chipotle rolled out a new line of bowls that included the Keto Salad Bowl, made with carnitas, romaine lettuce, red salsa, cheese, and guacamole.
