How to use the numbers
Protein Style replaces the bun with lettuce, but it does not make every configuration nutritionally identical. Onion, spread, cheese and other changes can alter the listed values. For an order that differs from the table, use In-N-Out's official nutrition page rather than estimating from a similarly named item.
