Blaze Pizza recently became the first national chain to announce a rollout of an official keto-diet-approved pizza crust. Blaze Pizza has a location at George Bush Intercontinental Airport (IAH) Terminal A7.

People adhering to keto diets limit their carbohydrate intake, pushing their bodies to switch into a fat-burning state called "ketosis." That means ditching sugar, wheat, and beans, and cutting back on alcohol. Red meat and cream are encouraged in the high-fat, low-carb diet.

The keto crust pizza contains just six grams of net carbs, swapping flour for ingredients like flaxseeds, eggs, and cheese.
