In-N-Out Protein Style Burger Low-Carb Guide to Lettuce-Wrapped Burgers
In-N-Out Burger’s “Protein Style” has become a phenomenon in the low-carb and ketogenic diet communities since its introduction as an official menu option. Simply put, Protein Style refers to any In-N-Out burger served without a traditional bun and instead wrapped in fresh, crisp iceberg lettuce leaves. This modification transforms the classic burger experience into a low-carb alternative that maintains all the flavors customers love while dramatically reducing carbohydrate content.
The concept originated organically from customer requests in the 1990s when low-carb diets began gaining mainstream popularity. Rather than refusing these special requests, In-N-Out embraced this customization and formally added it to their accommodation options, training all staff to prepare lettuce-wrapped versions of any burger on the menu.
What sets In-N-Out’s Protein Style apart from similar offerings at other chains is the quality and preparation of the lettuce wrap. The restaurant uses fresh, crisp iceberg lettuce that’s carefully selected and prepared to provide structural integrity while maintaining the burger’s visual appeal and eating experience.
