Protein Style
The In-N-Out Protein Style burger is a famous and secret menu item that replaces traditional buns with fresh, crisp, and healthy lettuce leaves. The burger contains a freshly cooked beef patty, American cheese, tomato slices, onions, and the brand’s signature spread, wrapped securely in lettuce. This variation provides a lower-calorie and reduced-carb alternative while retaining the classic In-N-Out flavor profile.
My first experience with the Protein Style burger occurred in 2018. Since that time, consistent enjoyment of this option has led to a preference for it over standard buns. The burger delivers high protein content with fewer calories, making it suitable for keto and low-carb diets. Its combination of freshness and flavor continues to appeal to health-conscious consumers.
