In-N-Out Burger calories: the best order for every goal
In-N-Out publishes its entire menu on one Nutrition Facts sheet, dated January 2026. Two modifications appear as their own rows in that official table, which almost no other chain does: Protein Style, which In-N-Out defines as the bun replaced with lettuce, and asking for mustard and ketchup instead of spread. Each saves real calories on any burger. Every figure below comes from that sheet.
